A quick and flavorful sheet pan fajitas recipe featuring juicy chicken or beef with roasted peppers and onions, perfect for busy weeknights and minimal cleanup.

Ingredients

Scale
  • 1.5 pounds boneless, skinless chicken breasts or thighs, thinly sliced (chicken thighs are juicier!)
  • OR 1.5 pounds flank steak or skirt steak, thinly sliced across the grain
  • 2 bell peppers (any colors), thinly sliced
  • 1 large yellow or white onion, thinly sliced
  • 2–3 cloves garlic, minced
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon dried oregano
  • ½ teaspoon garlic powder
  • ¼ teaspoon cayenne pepper (optional)
  • Salt and freshly ground black pepper to taste
  • 2 tablespoons olive oil or avocado oil
  • Juice of 1 lime
  • Fresh cilantro, chopped, for garnish (optional)
  • Warm flour or corn tortillas, for serving

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Slice your protein and vegetables thinly. For steak, slice against the grain; for chicken, thin slicing ensures juicy bites.
  3. In a large bowl, combine chili powder, cumin, smoked paprika, oregano, garlic powder, cayenne (if using), salt, and pepper.
  4. Add the sliced chicken or beef to the bowl, drizzle with 1 tablespoon olive oil, and toss to coat thoroughly.
  5. Add sliced peppers, onions, and minced garlic to the same bowl. Drizzle with remaining tablespoon of oil and toss again with the meat and seasoning.
  6. Spread everything evenly on your sheet pan in a single layer, avoiding overcrowding.
  7. Roast in the preheated oven for 20-25 minutes. Halfway through, use tongs to flip and toss everything for even browning.
  8. Once cooked through and browned, remove from the oven. Squeeze fresh lime juice over the top and sprinkle with chopped cilantro.
  9. Serve immediately with warm tortillas and your favorite toppings like sour cream, guacamole, shredded cheese, or salsa.

Notes

Use thin, even slices for faster cooking and better texture. Avoid overcrowding the pan to prevent steaming. For extra char, broil 1-2 minutes at the end but watch closely. Check chicken internal temperature reaches 165°F (74°C). For gluten-free, use corn tortillas. For dairy-free, skip cheese and sour cream or add avocado slices.
