Ingredients
  

For the Shrimp and Vegetables
  • 1 pound large shrimp peeled and deveined
  • 3 bell peppers thinly sliced (red, yellow, and green)
  • 1 medium red onion thinly sliced
  • 2 tablespoons olive oil
  • Juice of 1 lime
For the Fajita Seasoning
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon crushed red pepper flakes optional
For Serving
  • 8 small flour or corn tortillas
  • Fresh cilantro chopped
  • Lime wedges
  • Sour cream
  • Sliced avocado
  • Salsa or pico de gallo

Method
 

  1. Preheat your oven to 425°F and prepare a large sheet pan with parchment paper or a light coating of oil. Spread sliced peppers and onions evenly across the pan to encourage roasting instead of steaming.
  2. Toss the vegetables with olive oil and half of the fajita seasoning until fully coated. Roast them for about 8 minutes so they soften slightly and begin caramelizing before the shrimp are added.
  3. Pat the shrimp dry and coat them with olive oil, lime juice, and the remaining seasoning blend. This helps the shrimp roast properly while building bold Tex Mex flavor.
  4. Add the shrimp to the hot sheet pan and return everything to the oven for 5 to 7 minutes. Cook until the shrimp turn pink and opaque while the vegetables develop lightly charred edges.
  5. Warm the tortillas in a skillet or oven and fill them with the cooked shrimp and vegetables. Add toppings like avocado, cilantro, salsa, sour cream, and lime wedges before serving immediately.

Notes

  • Roast the vegetables first because peppers and onions take longer to soften than shrimp. This keeps the shrimp from overcooking while still giving the vegetables proper texture and color.
  • Patting the shrimp dry before seasoning helps them roast instead of steam. This simple step improves flavor concentration and gives better texture overall.
  • Use a large enough sheet pan so the ingredients stay in a single layer. Proper spacing allows heat to circulate evenly and creates lightly caramelized vegetables.
  • Warm tortillas just before serving because soft warm tortillas hold the filling better and make the fajitas much more enjoyable to eat.
