This cheesy ground turkey casserole goes from stovetop to oven in a single skillet, so you get a hot, bubbly dinner with very little cleanup. The pasta cooks right in the tomato sauce, which saves time and makes every bite saucy.

It is the kind of meal you can count on when you need something hearty that does not ask for a lot of fuss.

Why This One Stays in the Rotation

The turkey stays tender because it simmers in a rich, herby sauce instead of drying out. A double hit of cheese gives you a gooey middle and a golden, almost crispy top.

I love that it works with pantry ingredients and whatever short pasta I have on hand. It tastes like you planned ahead even on nights when you definitely did not.

Ingredients

1 tbsp olive oil: for browning the turkey
1 lb (450g) ground turkey: 93% lean keeps it light without drying out
1 small yellow onion, diced: white onion works too
2 garlic cloves, minced: or ½ tsp garlic powder in a pinch
1 can (15 oz) tomato sauce: plain, not seasoned
1 can (14.5 oz) diced tomatoes, undrained: the juice builds the sauce
1 cup chicken broth: vegetable broth or water both work
2 cups uncooked elbow macaroni: any short pasta like rotini or penne is fine
1 tsp dried oregano: or Italian seasoning
½ tsp salt
¼ tsp black pepper
1 cup shredded mozzarella: whole-milk melts best
½ cup grated Parmesan: adds a salty, nutty bite
Fresh basil for garnish: optional, but it brightens the dish

Variations / Substitutions

Swap the protein: lean ground beef or ground chicken both work. Drain any extra fat after browning if needed.
Change up the cheese: a sharp cheddar or Monterey Jack gives a different flavor. Use the same total amount.
Add vegetables: stir in a handful of baby spinach at the end of cooking, or a diced bell pepper with the onion.
Make it spicy: a pinch of red pepper flakes added with the oregano wakes everything up.
Dairy-free: use your favorite plant-based shredded mozzarella and skip the Parmesan, or swap in nutritional yeast.

You might also like a creamy chicken and rice casserole if you’re in the mood for something with a different texture.

How to Make One-Pan Cheesy Ground Turkey Casserole

Step 1: Brown the Turkey and Onion

Heat the 1 tbsp olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Add the 1 lb ground turkey and cook for about 6 minutes, breaking it up with a wooden spoon, until it loses its pink color. Toss in the diced onion and cook until softened, about 4 more minutes, then stir in the 2 minced garlic cloves and let them go for 30 seconds until fragrant.

The turkey will release some moisture at first. That is fine, keep cooking until the liquid cooks off and the meat starts to sizzle. You want a little bit of browning on the bottom for deeper flavor.

Step 2: Build the Sauce and Add the Pasta

Pour in the 15 oz can of tomato sauce, the 14.5 oz can of diced tomatoes with their juices, 1 cup chicken broth, 1 tsp dried oregano, ½ tsp salt, and ¼ tsp black pepper. Stir everything together and bring the mixture to a simmer. Let it bubble gently for 5 minutes so the flavors come together.

Add the 2 cups uncooked elbow macaroni and stir to coat the pasta in the sauce. Lower the heat to medium-low, cover the skillet, and cook for 8 to 10 minutes, stirring once halfway through. The pasta will soak up a lot of the liquid and turn just tender, with a little sauce still pooling around it.

Step 3: Top with Cheese and Bake

While the pasta finishes, preheat your oven to 375°F (190°C). When the pasta is ready, remove the skillet from the heat. Sprinkle the 1 cup shredded mozzarella and ½ cup grated Parmesan evenly over the top.

Slide the skillet into the oven and bake, uncovered, for 20 minutes. You will see the sauce bubbling around the edges and the cheese fully melted. At that point the casserole is hot through and the pasta is perfectly cooked.

Step 4: Broil and Serve

Switch the oven to broil and let the top get golden and spotty brown, about 2 to 3 minutes. Watch closely because the cheese can go from golden to burnt quickly.

Pull the skillet out and let it rest for 5 minutes off the heat so everything sets up. Scatter fresh basil over the top if you like, then spoon the casserole right from the pan onto plates. It is creamiest when it is still warm and the cheese is stretchy.

Tips for the Best Casserole

Do not overcook the pasta on the stovetop.: It should still have a little bite before going into the oven because it will continue to soften as it bakes.
Use a skillet that can handle the broiler.: If you are not sure, transfer the mixture to a greased 9×13 baking dish before topping with cheese.
Let the casserole rest.: Those few minutes off the heat keep the sauce from running all over the plate.
Watch the broiler.: Leave the oven light on and check every 30 seconds after the first minute. A dark spotty top is perfect; black is not.

Storing Leftover Casserole

Refrigerate: Cool completely, then cover and store in the fridge for up to 4 days.
Reheating: Warm individual portions in the microwave, or reheat the whole dish in a 350°F oven covered with foil until heated through, about 15 minutes.
Serve cold: This is not great cold because the cheese firms up and the sauce thickens, so reheating is best.

What to Serve with One-Pan Cheesy Ground Turkey Casserole

A bright, lemony arugula salad cuts the richness of the cheese and sauce. The peppery greens and a sharp vinaigrette balance every creamy bite. If you want something more substantial, a loaf of warm garlic bread is always welcome for swiping up any leftover sauce.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble it through the stovetop step, transfer to a baking dish if needed, top with cheese, and refrigerate overnight. The next day, bake at 375°F for 25 to 30 minutes until bubbly, then broil.

Can I freeze it?

You can freeze the baked, cooled casserole in an airtight container for up to 3 months. Thaw overnight in the fridge and reheat in the oven.

What if I don’t have an oven-safe skillet?

After the pasta simmers, pour everything into a greased 9×13 inch baking dish. Top with cheese and bake as directed.

Can I use a different pasta shape?

Yes. Any short cut like rotini, penne, or shells will work. Avoid long noodles or very small shapes like orzo, which can overcook.
