Bold Fajita Flavor Without Extra Work

A squeeze of fresh lime juice at the end wakes everything up. The cilantro adds freshness, and the toppings let everyone customize their fajitas.
Ingredients You’ll Need
Chicken, Peppers, Onions, and Tortillas
Chicken breasts: Use 1 1/2 pounds boneless skinless chicken breasts. Slice the chicken against the grain into 1/2-inch thick strips so it cooks quickly and stays tender.
Bell peppers: A mix of green, yellow, and red bell peppers adds color, sweetness, and classic fajita flavor. Slice them into strips.
Yellow onion: Thinly sliced onion roasts with the peppers and adds sweetness.
Garlic: Fresh minced garlic gives the fajitas a savory base.
Olive oil: Olive oil helps coat the chicken and vegetables so the seasoning sticks and everything roasts evenly.
Lime: Fresh lime juice adds brightness after baking.
Cilantro: Chopped cilantro adds fresh flavor before serving.
Flour tortillas: Small flour tortillas are soft, warm, and perfect for filling with chicken and vegetables.
Toppings: Sour cream, sliced avocado, guacamole, pico de gallo, and shredded cheese all work well.
Homemade Fajita Seasoning
The seasoning is simple but flavorful. You will need:
- 1 tablespoon chili powder
- 1 1/2 teaspoons paprika
- 1 1/2 teaspoons cumin
- 1/2 teaspoon onion powder
- 1/2 teaspoon garlic powder
- 1/4 teaspoon dried oregano
- 1/4 teaspoon cayenne pepper, optional
- 1 1/2 teaspoons salt
- 3/4 teaspoon freshly ground black pepper
Cayenne adds heat, but you can leave it out for a mild family-friendly version. You can also make the seasoning several days ahead and store it in a small jar at room temperature.
How to Make Sheet Pan Chicken Fajitas
Season the Chicken and Vegetables
Lightly grease a large sheet pan with nonstick cooking spray. Slice the chicken and vegetables into strips.
Spread the vegetables evenly on the sheet pan, then place the chicken strips on top. Preheat the oven to 425°F.
In a small bowl, combine the chili powder, paprika, cumin, onion powder, garlic powder, oregano, cayenne if using, salt, and black pepper. Stir until well mixed.
Sprinkle most of the seasoning over the chicken and some over the vegetables. Spoon the minced garlic over the chicken, then drizzle olive oil over the entire pan.
Toss everything well until the chicken and vegetables are evenly coated. Spread the mixture into an even layer across the sheet pan.
Bake, Finish, and Serve
Bake for 15 to 20 minutes, or until the chicken is cooked through and reaches 165°F. During the last 5 minutes of baking, wrap the flour tortillas in foil and place them in the oven to warm.
Remove the sheet pan from the oven. Squeeze fresh lime juice over the chicken and vegetables, then sprinkle with chopped cilantro.
Serve the fajitas in warm tortillas with sour cream, avocado, guacamole, pico de gallo, shredded cheese, or any toppings you like.
Tips, Variations, Storage, and FAQs
Tips for the Best Results
Slice the chicken against the grain. This helps keep the chicken tender instead of chewy.
Cut the chicken and vegetables into similar-sized strips so they cook evenly.
Do not overcrowd the pan. If the ingredients are piled too high, they may steam instead of roast. Use two sheet pans if needed.
Check the chicken for doneness. Chicken should reach 165°F for safe serving.
Warm the tortillas before serving. This makes the fajitas softer, more flexible, and easier to fold.
