Quick Sheet Pan Shrimp Fajitas
Sheet pan shrimp fajitas turn a weeknight dinner into something that feels a little celebratory, without piling up dishes. The whole meal roasts on a single pan under the broiler, so cleanup barely exists and the shrimp cook in minutes.
The peppers and onions get soft and charred, the seasoning is bold but simple, and you pile everything into warm tortillas with whatever toppings you have around. It comes together in about 25 minutes, tastes like more work than it is, and leaves you with just one pan to wash.
What Makes These Fajitas So Good
The broiler does all the heavy lifting. It blisters the pepper skins and gives the onions those dark, sweet edges while the shrimp turn pink and juicy on the same pan. You get real fajita flavor without a screaming-hot skillet or a grill.
The spice blend uses pantry staples you probably already own, and the whole thing is forgiving. Use whatever color peppers you like, swap the toppings around, and in twenty minutes you have a meal that feels pulled together, not rushed.
Ingredients
- 1 lb large shrimp, peeled and deveined: tail-off makes them easier to eat in tacos, but tails add a little flavor if you leave them on
- 2 bell peppers (any color): sliced into thin strips
- 1 medium red onion: sliced into thin wedges
- 2 tbsp olive oil: divided
- 1 1/2 tsp chili powder
- 1 tsp ground cumin
- 1/2 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/4 tsp dried oregano
- 1/8 tsp cayenne pepper (optional): skip it for mild fajitas
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1 lime: juiced
- 8 small flour or corn tortillas: warmed
- Toppings: sour cream, diced avocado, chopped cilantro, salsa, crumbled cotija or queso fresco
Variations / Substitutions
- Corn tortillas: use them instead of flour for a gluten-free option; warm them especially well so they don’t crack
- Spice level: add an extra pinch of cayenne or a few slices of fresh jalapeño tossed with the vegetables
- Dairy-free: skip the sour cream and cheese, and add extra avocado or a spoonful of dairy-free crema
- Different protein: thinly sliced chicken breast or thighs work great; increase the cook time and check for doneness

How to Make Sheet Pan Shrimp Fajitas
Step 1: Toss and Roast the Peppers and Onions
Preheat your broiler with a rack set about 6 inches from the heat. In a small bowl, stir together the 1 1/2 teaspoons chili powder, 1 teaspoon cumin, 1/2 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon oregano, optional 1/8 teaspoon cayenne, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Place the 2 sliced bell peppers and 1 sliced red onion on a large sheet pan. Drizzle with 1 tablespoon of the olive oil and sprinkle over half of the spice mixture. Toss everything with your hands until evenly coated, then spread it into a single layer.
Roast the vegetables under the broiler until they soften and the edges start to char. This usually takes about 5 to 7 minutes, but check at the 4-minute mark because broilers vary a lot. You want visible dark spots but not burning.
Step 2: Season the Shrimp
While the vegetables roast, pat the 1 pound of shrimp very dry with paper towels. In a medium bowl, toss them with the remaining 1 tablespoon olive oil and the rest of the spice blend you set aside. Use your hands to make sure every shrimp gets coated.
Let the shrimp sit while the peppers finish. Even a few minutes lets the spices cling and the salt start to season the surface, which helps the shrimp taste more savory once they hit the heat.
Step 3: Broil the Shrimp
Pull the sheet pan out of the oven and scatter the seasoned shrimp over the peppers and onions in a loose single layer. If the veggies are crowded in one spot, push them apart a little so the shrimp have room. Return the pan to the broiler and cook just until the shrimp turn pink and opaque, about 3 to 4 minutes.
Keep a close eye on them. Shrimp curl into a gentle “C” shape when they are done, and if they start to look tight and wrinkled, they have gone a step too far. The residual heat from the pan will keep cooking them for a minute after you pull them out, so err on the side of pulling them early.
Step 4: Assemble the Fajitas
Remove the pan from the oven and squeeze the juice of 1 lime over everything right away. Warm the 8 tortillas on a dry skillet for about 20 seconds per side or directly over a gas flame for a few seconds. Pile the shrimp, peppers, and onions into the tortillas and add whatever toppings you like.
Bring the pan to the table and let everyone build their own. The contrast of the hot, charred filling with cool sour cream and creamy avocado is what makes each bite work, so don’t skip the cold toppings.
Tips for the Best Sheet Pan Fajitas
- Patting the shrimp completely dry before they hit the seasoning keeps them from steaming under the broiler. Even a little water makes them less likely to char.
- Use the biggest sheet pan you have so the vegetables and shrimp roast in a single layer with a little space between pieces. Crowding makes everything soggy.
- Broil just until shrimp turn pink and curl loosely. Any longer and they go rubbery fast, so set a timer and check a minute early.
- Tortillas taste best with a few charred spots. A dry skillet or an open gas flame gives them that warm, toasty edge in seconds.
Keeping Leftover Fajitas Fresh
- Refrigerate: Store the shrimp and vegetables together in an airtight container for up to 2 days. Keep tortillas and toppings separate so nothing gets mushy.
- Reheating: Gently warm the shrimp and veggies in a skillet with a small splash of water over medium heat. They won’t be as tender as fresh but will still taste good. Avoid the microwave, which can make shrimp tough.
What to Serve With Sheet Pan Shrimp Fajitas
A side of cilantro-lime rice soaks up the pan juices and rounds out the plate without needing extra dishes. Creamy black beans or refried beans bring some heartiness, and a quick cabbage slaw with lime and a pinch of salt adds crunch that plays off the warm, soft filling.
Frequently Asked Questions
Can I use frozen shrimp?
Yes, just thaw them completely under cold running water, then pat very dry before seasoning. Any leftover moisture will steam the shrimp instead of letting them char.
Can I swap in chicken instead of shrimp?
Absolutely. Use thin strips of boneless skinless chicken breast or thigh, increase the vegetable roast time by a couple of minutes to account for the longer cook, and broil the chicken until cooked through, roughly 6 to 8 minutes.
What if I don’t have a broiler?
You can roast at 450°F instead. The vegetables will take about 12 to 15 minutes to brown and soften, and the shrimp will need around 5 to 6 minutes, though you won’t get the same quick char.
My shrimp turned out rubbery. What went wrong?
Shrimp cook extremely fast and keep cooking from the heat of the pan once you pull them out. Remove them the moment they turn opaque, and serve right away to avoid overdoing it.
