Ingredients & Equipment
Ingredients
- 1 pound shrimp, peeled and deveined
- 2 bell peppers, sliced (mixed colors if possible)
- 1 onion, sliced (yellow or red)
- 2 tablespoons olive oil
- 2 teaspoons chili powder
- 1 teaspoon cumin
- 1 teaspoon garlic powder
- Salt and pepper to taste
- Tortillas, for serving (flour or corn)
- Lime wedges, for serving
Notes
- Use medium to large shrimp for best texture; if using frozen shrimp, thaw completely and pat dry.
- Bell peppers add sweetness and color — a mix of red, yellow, and green looks lovely.
- Adjust the chili powder to taste; use smoked paprika for a milder, smoky note.
Helpful tools and equipment
- Large rimmed baking tray (sheet pan) — choose one with a rim to contain juices
- Mixing bowl (large)
- Tongs or spatula
- Sharp knife and cutting board
- Paper towels (to dry shrimp)
- Optional: instant-read thermometer (useful for checking protein doneness)
- Optional: blender or small food processor if you want to make a quick sauce or marinade
Step-by-Step Instructions (with tips)
1. Preheat and prep
- Preheat the oven to 400°F (200°C). A hot oven is key to getting a slight roast on the peppers while cooking the shrimp quickly.
- Rinse shrimp under cold water if needed, then pat completely dry with paper towels — dry shrimp sear and roast better than wet shrimp.
- Slice bell peppers and onion into even strips so everything cooks at the same rate.
Tip: For more caramelized vegetables, cut them slightly thinner. If you prefer your veggies a little crisper, cut them a touch thicker.
2. Season the shrimp and vegetables
- In a large bowl, combine the shrimp, bell peppers, onion, olive oil, chili powder, cumin, garlic powder, salt, and pepper.
- Toss until everything is evenly coated. Taste a tiny piece of raw pepper (not shrimp) tossed in the seasoning to check salt and spice balance before adding the shrimp.
Tip: If you like extra brightness, add the zest of one lime to the mixture before roasting. For a touch of heat, sprinkle a pinch of cayenne or add sliced jalapeño to the pan.
3. Spread on the sheet pan
- Spread the mixture evenly on a sheet pan in a single layer. Give the ingredients enough room — crowding causes steaming rather than roasting.
- If you want some char on the vegetables, arrange the peppers and onions on one half of the tray and place the shrimp on the other so you can easily broil the veggies for a minute at the end if desired.
Tip: Line the sheet pan with parchment paper or a silicone liner for easier cleanup. If using aluminum foil, lightly oil it to prevent sticking.
4. Bake until cooked through
- Bake for 15–20 minutes or until the shrimp are cooked through and vegetables are tender. Shrimp should turn opaque and firm to the touch.
- If you like a little extra color, broil for 1–2 minutes at the end, watching closely so nothing burns.
Variation: Roast vs. Sear — If you prefer, roast the peppers and onion for 12–15 minutes first, then add shrimp for the final 6–8 minutes so the shrimp stay extra tender. Alternatively, you can cook the vegetables in a hot skillet on the stovetop until charred and then toss with quickly sautéed shrimp for a slightly different texture.
Tip: If swapping proteins, this pan method works beautifully with chicken thighs or breasts. For a tested chicken idea and timing inspiration, see the original sheet pan chicken pitas recipe.
5. Serve
- Transfer the shrimp, peppers, and onions to a serving dish or directly to warm tortillas.
- Squeeze lime wedges over the top, and offer extra lime for folks who love a bright finish.
Flavor suggestions: Top with chopped cilantro, a dollop of Greek yogurt or labneh (for a creamy twist), sliced avocado, or pickled onions. Sprinkle with crumbled feta or cotija if you use dairy, or go dairy-free with an herbed tahini drizzle.
Storage, Freezing & Make-Ahead Tips
Storing leftovers
- Refrigerate cooked shrimp fajitas in an airtight container within two hours of cooking. They’ll keep well for 2 days in the fridge. Shrimp texture softens over time, so consume sooner rather than later for best quality.
- Store tortillas separately, wrapped in foil or a sealed container to avoid drying out.
Freezing
- You can freeze the cooked shrimp and vegetables in a single layer on a sheet tray first, then transfer to freezer bags for up to 2 months. Reheat from frozen in a 350°F (175°C) oven until warmed through.
- For longer-term freezing, freeze raw seasoned shrimp (before roasting) in a sealed bag for up to 3 months; thaw overnight in the fridge before roasting.
Make-ahead advice
- Prep the vegetables and seasoning mix up to a day ahead and store them in the refrigerator. Keep the shrimp separate and add them to the vegetables when you are ready to roast.
- If bringing this to a potluck, roast on-site or keep warm in an insulated carrier. Reheat gently to avoid overcooking the shrimp.
Portioning tips
- This recipe with 1 pound shrimp typically serves 3–4 as a main with sides or 4–6 with generous sides like rice and beans.
- For meal prep, divide into individual containers with tortillas and lime wedges for easy reheats.

FAQ
Q: Can I use frozen shrimp?
A: Yes. Thaw frozen shrimp completely in the refrigerator overnight or under cold running water. Pat dry before seasoning and roasting to avoid excess moisture that prevents browning.
Q: How can I make this recipe milder or spicier?
A: For milder fajitas, reduce the chili powder or omit any added hot peppers. For more heat, add sliced jalapeños, a pinch of cayenne, or a drizzle of spicy sauce after cooking.
Q: What if I don’t have a sheet pan?
A: Use a rimmed baking dish or two smaller baking sheets to spread the ingredients out in a single layer. The key is not to overcrowd the pan so the shrimp and vegetables roast rather than steam.
Q: How do I know when the shrimp are done?
A: Shrimp are done when they’re opaque and firm, with no translucent center. Overcooking makes them rubbery, so rely on visual cues and feel rather than just time.
Q: Can I make this gluten-free?
A: Absolutely. Use gluten-free corn tortillas or certified gluten-free flour tortillas. Check any spice mixes for hidden gluten.
