Ingredients

Scale
  • 1 lb boneless, skinless chicken breasts or thighs, thinly sliced
  • 1 lb flank steak or skirt steak, thinly sliced
  • 2 bell peppers, assorted colors, sliced into strips
  • 1 large onion, thinly sliced (yellow or red)
  • 2 teaspoons 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)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons olive oil
  • Juice of 1 lime
  • Fresh cilantro, chopped (optional)
  • Flour or corn tortillas, warmed, for serving

Instructions

  1. Preheat the oven to 425°F (220°C).
  2. Slice the chicken breasts or steak into thin strips about 1/2-inch thick. Slice bell peppers and onion into similar-sized strips.
  3. In a small bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne pepper, salt, and black pepper.
  4. Place sliced meat and veggies in a large mixing bowl. Drizzle olive oil and lime juice over them. Sprinkle the seasoning blend on top and toss until evenly coated.
  5. Spread the meat and veggies out in a single layer on a baking sheet, avoiding overcrowding.
  6. Bake for 20-25 minutes, flipping halfway through, until meat is cooked through and veggies are tender but crisp.
  7. Remove from oven and let rest for a few minutes. Sprinkle with chopped cilantro if desired.
  8. Warm tortillas while fajitas rest. Serve meat and veggies in warm tortillas with your favorite toppings.

Notes

Do not overcrowd the pan to avoid steaming. Slice meat and veggies evenly for uniform cooking. Flip halfway through baking for even browning. Rest fajitas after baking to lock in juices. For gluten-free, use almond flour tortillas. For vegetarian, substitute meat with portobello mushrooms or tofu. Use avocado oil for higher smoke point if preferred.
