11 High Protein Spaghetti Squash Recipes That Actually Fill You Up

High protein spaghetti squash recipes take the same smart base, a roasted squash scraped into tender strands, and pair it with chicken, turkey, shrimp, beef, eggs, or chickpeas so your bowl has real staying power. The squash brings lightness without tasting watery, and the toppings deliver the sauce, salt, and texture that make dinner feel complete. The versions below run from classic meat sauce to a bright Thai peanut bowl, all built on that same foundation.

Start with the turkey meat sauce if you want the crowd-friendly classic. Go for the Cajun skillet when you want heat, the buffalo casserole if creamy and spicy sounds right, and the green chile breakfast bowls when you need meal prep that reheats well.

Which High Protein Spaghetti Squash Recipe Should You Make?

Classic Turkey Meat Sauce Spaghetti Squash

This is the version I keep coming back to when a weeknight meal needs to be sturdy and unfussy. A slow-simmered turkey meat sauce gives you plenty of protein over a big pile of squash strands, with just enough Parmesan to round the tomato.

Ingredients (makes 4 servings)

• Spaghetti squash, halved lengthwise and seeded: 1 large, about 1.2 kg (2.6 lb)
• Olive oil: 2 tbsp, divided
• Kosher salt: 1 tsp, divided
• Lean ground turkey: 450 g (1 lb)
• Yellow onion, finely diced: 1 medium
• Garlic cloves, minced: 4
• Crushed tomatoes: 794 g (28 oz)
• Dried oregano: 1 tsp
• Red pepper flakes: 1/4 tsp
• Parmesan cheese, finely grated: 50 g (1/2 cup)

Instructions

Step 1: Heat the oven to 400°F (200°C). Brush the cut sides of your squash with 1 tbsp olive oil and sprinkle with 1/2 tsp salt. Place them cut side down on a sheet pan and roast for 40 to 45 minutes, until a fork slides through the skin with no resistance. You’ll know it’s ready when the strands pull away easily at the edges.

Step 2: While the squash roasts, warm the remaining 1 tbsp oil in a large skillet over medium-high. Add the 450 g ground turkey and cook for 6 to 8 minutes, breaking it up as it browns. You want it fully cooked and starting to crisp at the edges before you add the onion.

Step 3: Stir in the onion and cook 5 minutes more, until it softens and the raw edge is gone. Add the 4 minced garlic cloves, 1 tsp oregano, 1/4 tsp red pepper flakes, and the remaining 1/2 tsp salt. Cook for 30 seconds, just until you can smell the garlic.

Step 4: Pour in the 794 g crushed tomatoes, stir, and lower the heat. Let it simmer for 10 minutes, stirring now and then, until the sauce thickens and you can taste that the flavors have settled. Adjust the salt if the tomatoes were sharp.

Step 5: Scrape the roasted squash into strands and pile it into a serving dish. Spoon the turkey sauce over the top and finish with the 50 g Parmesan. Serve hot, with extra cheese on the side if you like.

Chicken Pesto Mozzarella Spaghetti Squash Bake

If you want a casserole that feels rich but still light, this baked version folds pesto and ricotta right into the squash. I go a little heavy on the mozzarella so the top gets those stretchy golden edges.

Ingredients (makes 5 servings)

• Spaghetti squash, halved and seeded: 1 large, about 1.4 kg (3 lb)
• Olive oil: 2 tbsp, divided
• Skinless chicken breast, cubed: 680 g (1.5 lb)
• Kosher salt: 3/4 tsp
• Garlic cloves, minced: 3
• Basil pesto: 113 g (1/2 cup)
• Ricotta cheese: 150 g (2/3 cup)
• Shredded mozzarella: 170 g (1.5 cups)
• Parmesan cheese, finely grated: 30 g (1/3 cup)
• Fresh basil leaves, torn: 1/4 cup

Instructions

Step 1: Heat the oven to 400°F (200°C). Halve and seed your squash, brush the cut sides with 1 tbsp oil, and roast cut side down for 45 minutes. You’ll know it’s ready when a knife meets no resistance and the strands look tender.

Step 2: While that roasts, pat the 680 g chicken dry and season with 3/4 tsp salt. Warm the remaining 1 tbsp oil in a large skillet over medium-high, add the chicken, and cook for 7 to 9 minutes, turning once, until golden on the outside and cooked through. Take the pan off the heat and let the chicken cool while you scrape the squash.

Step 3: Once the squash is cool enough to touch, scrape the strands into a large bowl. Fold in the cooled chicken, 3 minced garlic cloves, 113 g pesto, 150 g ricotta, and half of the 170 g mozzarella. You want the filling streaked with green and creamy in spots, not one uniform color.

Step 4: Pile the mixture back into the squash shells or into a 2 L baking dish. Scatter the remaining mozzarella and all 30 g Parmesan over the top, then bake for 15 to 20 minutes, until the cheese melts and the edges bubble. Finish with the 1/4 cup torn basil and serve right from the dish.

Garlic Butter Shrimp Spaghetti Squash Scampi

This is the one to make when you want dinner fast but it still feels special. The shrimp cook in lemon butter while the squash roasts, and the garlic hits hard in the best way.

Ingredients (makes 4 servings)

• Spaghetti squash, halved and seeded: 1 medium, about 1.1 kg (2.4 lb)
• Olive oil: 1 tbsp
• Unsalted butter: 3 tbsp, divided
• Large shrimp, peeled and deveined: 680 g (1.5 lb)
• Kosher salt: 1/2 tsp
• Garlic cloves, thinly sliced: 5
• Lemon: 1, zested and juiced
• Fresh parsley, chopped: 1/4 cup
• Red pepper flakes: 1/4 tsp
• Parmesan cheese, finely grated: 30 g (1/3 cup)

Instructions

Step 1: Heat the oven to 425°F (220°C). Rub your squash cut sides with 1 tbsp olive oil, set them cut side down on a sheet pan, and roast for 35 to 40 minutes. The squash is ready when you can twist a fork and the strands separate cleanly.

Step 2: Once the squash is cool enough, scrape the strands into a bowl and keep them warm. You can leave the shells for serving or discard them.

Step 3: Melt 2 tbsp of the butter in a large skillet over medium-high. Pat the 680 g shrimp dry, season with 1/2 tsp salt, and sear them for 90 seconds per side. You want golden edges but not fully cooked centers, because they finish in the sauce.

Step 4: Add the remaining 1 tbsp butter, 5 sliced garlic cloves, and 1/4 tsp red pepper flakes to the skillet. Cook for 30 seconds, until the garlic smells toasty and you see it turn pale gold, then pour in the lemon juice and zest. Return the shrimp and toss for 1 to 2 minutes, until they curl and turn opaque throughout.

Step 5: Toss the buttery shrimp and sauce with the squash strands and the 1/4 cup parsley. Finish with the 30 g Parmesan and serve hot, with extra lemon wedges if you have them.

Cajun Chicken Sausage Spaghetti Squash Skillet

A skillet version for nights when you want serious Cajun flavor and very little washing up. I brown the chicken sausage until it sticks to the pan, then build the sauce right on those crispy bits.

Ingredients (makes 5 servings)

• Spaghetti squash, halved and seeded: 1 large, about 1.4 kg (3 lb)
• Olive oil: 2 tbsp, divided
• Chicken sausage, sliced into coins: 340 g (12 oz)
• Red bell pepper, thinly sliced: 1
• Green bell pepper, thinly sliced: 1
• Yellow onion, thinly sliced: 1 medium
• Garlic cloves, minced: 4
• Cajun seasoning: 1 tbsp
• Crushed tomatoes: 411 g (14.5 oz)
• Kosher salt: 1/2 tsp

Instructions

Step 1: Heat the oven to 400°F (200°C). Rub the cut sides of your squash with 1 tbsp oil and roast cut side down for 40 to 45 minutes, until the flesh gives when you press the skin. Set it aside to cool slightly.

Step 2: Warm the remaining 1 tbsp oil in a large oven-safe skillet over medium-high. Add the 340 g chicken sausage coins and cook for 5 to 6 minutes, turning once, until deeply browned on both sides. You want those browned bits on the bottom for flavor.

Step 3: Add the red bell pepper, green bell pepper, and onion to the skillet. Cook for 8 minutes, stirring every few minutes, until the vegetables soften and pick up the sausage drippings. You’ll see the onion turn translucent and the peppers collapse a little.

Step 4: Stir in 4 minced garlic cloves and 1 tbsp Cajun seasoning and cook for 30 seconds, just until you smell the spice. Pour in the 411 g crushed tomatoes and 1/2 tsp salt, scraping the bottom of the skillet with your spoon.

Step 5: Simmer the sauce for 8 to 10 minutes, until it is thick enough to coat the back of your spoon. Scrape the roasted squash strands into the skillet and fold everything together over medium heat for 2 minutes, just until the squash is hot and coated.

Step 6: Serve straight from the skillet while the sauce is still loose and shiny. Pass extra hot sauce at the table if you like that kind of heat.

Taco Beef Spaghetti Squash Boats

Taco night, but you eat the bowl. These boats are packed with seasoned beef, cheese, and a cold sour cream finish, so nobody misses the tortillas.

Ingredients (makes 4 servings)

• Spaghetti squash, halved lengthwise and seeded: 1 large, about 1.5 kg (3.3 lb)
• Olive oil: 1 tbsp
• Lean ground beef: 450 g (1 lb)
• Yellow onion, diced: 1 small
• Garlic cloves, minced: 3
• Mild taco seasoning: 2 tbsp
• Tomato sauce: 340 g (1.5 cups)
• Shredded cheddar cheese: 113 g (1 cup)
• Sour cream: 120 g (1/2 cup)
• Fresh cilantro, chopped: 1/4 cup

Instructions

Step 1: Heat the oven to 400°F (200°C). Brush the cut sides of your squash with 1 tbsp olive oil and roast cut side down for 40 to 45 minutes, until a fork pierces the skin with no effort. Set it aside until it’s cool enough to handle.

Step 2: While the squash roasts, warm a large skillet over medium-high and add the 450 g ground beef. Cook for 7 to 8 minutes, breaking it up with your spoon, until no pink remains and the edges start to crisp. Stir in the onion and cook 4 minutes, until it softens.

Step 3: Add the 3 minced garlic cloves and 2 tbsp taco seasoning. Cook for 30 seconds, until the spice darkens and smells toasted, then pour in the 340 g tomato sauce. Simmer for 8 minutes, so your beef is shreddy and the sauce clings to it.

Step 4: Scrape the squash into strands with your fork, leaving them attached in the shells. Fold half of the 113 g cheddar into the beef, then pile the meat into the two squash boats. Scatter the remaining cheddar over the top.

Step 5: Broil the boats on high for 3 to 4 minutes, until the cheese melts and you see browning at the edges. Top with dollops of the 120 g sour cream and the 1/4 cup cilantro, and serve warm.

Thai Peanut Chicken Spaghetti Squash

This peanut sauce clings to the squash in a way that makes the whole bowl taste glossy and bright. I add a little extra lime at the end because the tang cuts through the nuts.

Ingredients (makes 4 servings)

• Spaghetti squash, halved and seeded: 1 medium, about 1.1 kg (2.4 lb)
• Olive oil: 1 tbsp
• Skinless chicken breast, sliced thin: 450 g (1 lb)
• Kosher salt: 1/2 tsp
• Natural peanut butter, unsweetened: 80 g (1/3 cup)
• Lime: 1, juiced
• Low sodium soy sauce: 3 tbsp
• Fresh ginger, grated: 1 tbsp
• Garlic cloves, minced: 3
• Fresh cilantro, chopped: 1/4 cup

Instructions

Step 1: Heat the oven to 400°F (200°C). Rub your squash cut sides with 1 tbsp olive oil, set them cut side down on a sheet pan, and roast for 35 to 40 minutes. You’ll know it’s done when the strands separate with a fork.

Step 2: While the squash roasts, pat the 450 g chicken dry and season with 1/2 tsp salt. Warm a large skillet over medium-high, add the chicken, and cook for 6 to 7 minutes, turning once, until golden and cooked through. Move the chicken to a plate while you whisk the sauce.

Step 3: In a small bowl, whisk together the 80 g peanut butter, lime juice, 3 tbsp soy sauce, 1 tbsp grated ginger, and 3 minced garlic cloves. You want the sauce thick but pourable, so add 2 tbsp water if it feels clumpy.

Step 4: Return the chicken to the skillet over medium heat and pour in the peanut sauce. Cook for 3 minutes, stirring gently, until the sauce clings to the chicken and you see a little sheen on the surface.

Step 5: Scrape the roasted squash into strands and pile them into bowls. Top with the saucy chicken and the 1/4 cup cilantro, and serve hot with extra lime wedges if you have them.

Buffalo Chicken Spaghetti Squash Casserole

For anyone who likes their comfort food spicy, this casserole brings buffalo heat with yogurt and cream cheese to keep it creamy. You can use rotisserie chicken to shave off ten minutes.

Ingredients (makes 6 servings)

• Spaghetti squash, halved and seeded: 1 large, about 1.5 kg (3.3 lb)
• Olive oil: 1 tbsp
• Shredded cooked chicken breast: 450 g (3 cups)
• Buffalo sauce: 120 ml (1/2 cup)

• Crumbled blue cheese: 30 g (1/4 cup)
• Green onions, sliced: 2

Instructions

Step 1: Heat the oven to 400°F (200°C). Brush your squash cut sides with 1 tbsp olive oil and roast cut side down for 45 minutes, until a knife slips through easily. Let it cool while you prep the filling.

Step 2: In a large bowl, stir together the 113 g cream cheese, 113 g Greek yogurt, 120 ml buffalo sauce, and 1 tsp garlic powder until smooth. You want the sauce thick enough to coat the chicken without turning watery.

Step 3: Fold in the 450 g shredded chicken and half of the 113 g mozzarella. Scrape the cooled squash strands into the bowl with your fork and stir until every strand has a little sauce on it.

Step 4: Transfer the mixture to a 2 L baking dish, scatter the remaining mozzarella and the 30 g blue cheese on top, and bake for 20 to 25 minutes. You’re looking for bubbling around the edges and a golden top. Let it sit for 5 minutes before you scoop it, then top with the 2 sliced green onions and serve hot.

Mediterranean Chickpea Feta Spaghetti Squash

A vegetarian version that still holds its own, thanks to crispy chickpeas and plenty of feta. I roast the squash hot so the strands keep a little snap under the creamy yogurt.

Ingredients (makes 4 servings)

• Spaghetti squash, halved and seeded: 1 medium, about 1.1 kg (2.4 lb)
• Olive oil: 3 tbsp, divided
• Chickpeas, drained and rinsed: 425 g (15 oz)
• Kosher salt: 1/2 tsp
• Smoked paprika: 1 tsp
• Cherry tomatoes, halved: 1 cup
• Kalamata olives, pitted and sliced: 1/3 cup
• Feta cheese, crumbled: 113 g (1 cup)
• Plain Greek yogurt: 80 g (1/3 cup)
• Lemon: 1, juiced

Instructions

Step 1: Heat the oven to 425°F (220°C). Rub your squash cut sides with 1 tbsp of the olive oil and roast cut side down for 35 to 40 minutes, until the flesh shreds easily. Set the shells aside while you crisp the chickpeas.

Step 2: Pat the 425 g chickpeas dry with a towel. Warm the remaining 2 tbsp oil in a large skillet over medium-high and add the chickpeas. Cook for 8 to 10 minutes, shaking the pan now and then, until they are crisp and you hear them rattle.

Step 3: Lower the heat to medium, add the 1 cup cherry tomatoes and 1 tsp smoked paprika, and cook for 3 minutes. You want the tomatoes to split and release a little juice without turning to mush.

Step 4: Turn off the heat and stir in the 1/3 cup olives, half of the 113 g feta, and the lemon juice. Scrape the squash strands into the skillet and fold everything together with your fork, so the chickpeas and tomatoes mix through.

Step 5: Spoon the mixture onto plates, dollop with the 80 g Greek yogurt, and scatter the remaining feta over the top. Serve warm, with a little extra lemon if you like it brighter.

Chicken Parmesan Spaghetti Squash Boats

All the parts of chicken Parmesan you love, served in a roasted squash boat. The broiler does the work at the end, giving you that blistered cheese top.

Ingredients (makes 4 servings)

• Spaghetti squash, halved lengthwise and seeded: 1 large, about 1.4 kg (3 lb)
• Olive oil: 1 tbsp
• Kosher salt: 1/2 tsp
• Shredded cooked chicken breast: 340 g (2.5 cups)
• Marinara sauce: 411 g (14.5 oz)
• Garlic powder: 1/2 tsp
• Dried Italian seasoning: 1 tsp
• Mozzarella cheese, shredded: 113 g (1 cup)
• Parmesan cheese, finely grated: 30 g (1/3 cup)
• Fresh basil leaves, torn: 1/4 cup

Instructions

Step 1: Heat the oven to 425°F (220°C). Rub the cut sides of your squash with 1 tbsp oil and sprinkle with 1/2 tsp salt. Roast cut side down for 35 to 40 minutes, until the flesh is tender but the shells still hold their shape.

Step 2: While the squash roasts, stir together the 340 g chicken, 411 g marinara, 1/2 tsp garlic powder, and 1 tsp Italian seasoning in a bowl. You want the chicken coated but not swimming, so drain the tomatoes a little if your sauce is thin.

Step 3: Once the squash is cool enough to handle, scrape the strands with your fork, leaving them in the shells. Fold half of the 113 g mozzarella and half of the 30 g Parmesan into the chicken mixture.

Step 4: Divide the chicken mixture between the squash boats, pressing it in gently so it reaches the edges. Top with the remaining mozzarella and Parmesan.

Step 5: Bake for 15 to 20 minutes, then broil for 2 to 3 minutes if you want a blistered top. Keep your eye on it so the cheese does not burn.

Step 6: Finish with the 1/4 cup basil and serve the boats whole, with extra marinara warmed on the side if you like yours extra saucy.

Air Fryer Turkey Meatball Spaghetti Squash

Turkey meatballs in the air fryer stay browned outside and juicy inside, and they cook while the squash finishes in the oven. I make a double batch of meatballs because they freeze so well.

Ingredients (makes 5 servings)

• Spaghetti squash, halved and seeded: 1 large, about 1.4 kg (3 lb)
• Olive oil: 2 tbsp, divided
• Lean ground turkey: 450 g (1 lb)
• Egg: 1 large
• Parmesan cheese, finely grated: 40 g (1/2 cup)
• Garlic cloves, minced: 3
• Dried oregano: 1 tsp
• Kosher salt: 1/2 tsp
• Panko breadcrumbs: 40 g (1/2 cup)
• Marinara sauce: 411 g (14.5 oz)

Instructions

Step 1: Heat the oven to 400°F (200°C). Brush the cut sides of your squash with 1 tbsp of the oil and roast cut side down for 40 to 45 minutes, until tender. You can also cook the squash in your air fryer at 380°F for 25 minutes if you want to keep it all in one appliance.

Step 2: While the squash roasts, mix the 450 g turkey, 1 egg, 40 g Parmesan, 3 minced garlic cloves, 1 tsp oregano, 1/2 tsp salt, and 40 g panko in a bowl. Stop mixing as soon as the ingredients come together, or your meatballs will be tough.

Step 3: Roll the mixture into 12 meatballs, each about 4 cm across. Arrange them in your air fryer basket in a single layer, brush with the remaining 1 tbsp oil, and cook at 400°F (200°C) for 10 to 12 minutes, shaking halfway. The meatballs should reach 74°C (165°F) in the center.

Step 4: Warm the 411 g marinara in a small saucepan over medium heat. Once the squash is done, scrape the strands into bowls with your fork and top each with 3 meatballs and a ladle of sauce.

Step 5: Finish with a little more Parmesan from the same block if you have it, and serve hot. The meatballs stay juicy, and the squash soaks up the marinara underneath.

Green Chile Egg Scramble Spaghetti Squash Bowls

Breakfast bowls that work just as well at 6 p.m. as at 9 a.m. Scrambled eggs, green chiles, and turkey sausage fold into squash strands for a plate that keeps you full for hours.

Ingredients (makes 3 servings)

• Spaghetti squash, halved and seeded: 1 medium, about 1.1 kg (2.4 lb)
• Olive oil: 2 tbsp, divided
• Lean ground turkey sausage, casings removed: 340 g (12 oz)
• Yellow onion, diced: 1 small
• Garlic cloves, minced: 2
• Large eggs: 6
• Diced green chiles, drained: 113 g (4 oz)
• Kosher salt and black pepper: 1/2 tsp and 1/4 tsp
• Shredded Monterey Jack cheese: 85 g (3/4 cup)
• Fresh cilantro, chopped: 1/4 cup

Instructions

Step 1: Heat the oven to 400°F (200°C). Rub your squash cut sides with 1 tbsp of the oil and roast cut side down for 35 to 40 minutes, until the flesh gives easily when you press it. Set it aside.

Step 2: While the squash roasts, warm the remaining 1 tbsp oil in a large skillet over medium-high. Add the 340 g turkey sausage and cook for 6 to 7 minutes, breaking it into small crumbles, until browned and cooked through. You’ll see it shrink and pick up color on the edges.

Step 3: Stir in the onion and cook 4 minutes, until it softens, then add the 2 minced garlic cloves and the 113 g green chiles. Cook for 1 minute so the chiles warm through and the garlic loses its raw bite. You’ll smell it right around the 1-minute mark.

Step 4: Crack the 6 eggs into the skillet, add the 1/2 tsp salt and 1/4 tsp black pepper, and reduce the heat to medium. Stir slowly for 2 to 3 minutes, folding the eggs through the sausage, until they are just set but still glossy. You want them slightly underdone because they keep cooking off the heat. Scrape the squash strands into the skillet or into bowls, scatter the 85 g Monterey Jack and 1/4 cup cilantro over the top, and fold once more. Serve hot.

The one step that matters across every version is roasting your squash until it shreds cleanly but still has a little bite. Soggy squash turns dinner into a bowl of mush, while slightly underdone strands hold up under sauce and cheese.

Pull it when a fork slides through the skin, not when the flesh is collapsing. Pick the version that sounds right tonight and let the squash do the light lifting.
