Ingredients

Scale
  • 1 pound large shrimp, peeled and deveined
  • 2 medium bell peppers, sliced into thin strips (mix of red, yellow, and green)
  • 1 large yellow or sweet onion, sliced into thin wedges
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (optional)
  • Salt and pepper to taste
  • Juice of 1 lime
  • A handful of fresh cilantro, chopped (optional)
  • Flour or corn tortillas, for serving

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice bell peppers and onion into thin strips and wedges, respectively.
  3. In a small bowl, combine chili powder, smoked paprika, ground cumin, garlic powder, onion powder, cayenne pepper, salt, and pepper to make fajita seasoning.
  4. In a large mixing bowl, toss the sliced peppers, onions, and shrimp with olive oil and fajita seasoning until evenly coated.
  5. Spread the shrimp and veggies evenly on a rimmed sheet pan, avoiding overcrowding.
  6. Roast in the oven for 12-15 minutes, stirring or flipping halfway through at about 7 minutes, until shrimp are pink and opaque and veggies have slight charred edges.
  7. If some veggies need more time, remove shrimp earlier to prevent overcooking and continue roasting veggies.
  8. Finish with a squeeze of fresh lime juice and sprinkle chopped cilantro on top.
  9. Serve immediately with warm tortillas and optional toppings like sour cream or guacamole.

Notes

Do not overcrowd the pan to avoid steaming; flip halfway through cooking for even browning. Remove shrimp as soon as they turn pink to prevent rubberiness. Warm tortillas just before serving. For gluten-free, use corn tortillas and check seasoning ingredients. Leftovers keep up to 2 days refrigerated; freeze shrimp and veggies separately for up to 1 month.
