A quick and easy sheet pan shrimp fajita recipe featuring smoky, charred peppers and onions, perfect for busy weeknights and fuss-free dinners.

Ingredients

Scale
  • 1 pound large shrimp, peeled and deveined
  • 2 medium bell peppers, mixed colors, sliced (about 1 cup each)
  • 1 medium yellow onion, thinly sliced
  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons fajita seasoning (blend of chili powder, cumin, smoked paprika, garlic powder, onion powder, and a pinch of cayenne)
  • 1 tablespoon fresh lime juice
  • Salt and pepper to taste
  • Optional garnishes: chopped fresh cilantro, sliced avocado, sour cream

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice 2 bell peppers and 1 yellow onion into thin strips, about 1/4-inch wide.
  3. In a large mixing bowl, toss the sliced peppers and onions with 1 tablespoon of olive oil and a pinch of salt and pepper. Spread them out evenly on half of your sheet pan.
  4. In the same bowl, add the shrimp. Drizzle 1 tablespoon olive oil over the shrimp, sprinkle with 2 tablespoons fajita seasoning, and toss well to coat evenly.
  5. Spread the shrimp out on the empty half of the sheet pan in a single layer.
  6. Place the sheet pan in the oven and roast for 10 minutes. At the 5-minute mark, use tongs or a spatula to stir and flip the shrimp and veggies gently.
  7. After 10 minutes, check if shrimp are opaque and pink with a slight golden edge. They should be firm but not rubbery.
  8. Remove the pan from the oven and immediately squeeze 1 tablespoon of fresh lime juice over everything. Toss gently to combine.
  9. Serve with warm tortillas, guacamole, or a side of black beans. Garnish with fresh cilantro if desired.

Notes

Do not overcrowd the pan to ensure even roasting and char. Use fresh shrimp if possible and pat dry if using frozen. Flip ingredients halfway through cooking for even color. Watch shrimp closely to avoid overcooking. Let shrimp and veggies rest briefly after roasting to meld flavors. For more heat, add jalapeños or cayenne pepper. Leftovers keep well for up to 2 days and reheat gently on stovetop or microwave.
