Ingredients for Oven Baked Chicken Fajitas
This fajita recipe uses everyday pantry spices and fresh ingredients you may already have on hand:
- 1 1/2 pounds boneless skinless chicken breast (cut into thin strips)
- 1 teaspoon chili powder
- 1/8 teaspoon cayenne pepper (optional for spice)
- 1/4 teaspoon paprika
- 1/2 teaspoon onion powder
- 1/2 teaspoon garlic powder
- 1/4 teaspoon cumin
- 1/2 teaspoon salt
- Dash of black pepper

How to Make Sheet Pan Chicken Fajitas
Follow these easy steps to make flavorful oven fajitas in just one pan:
Step 1: Preheat Oven
Preheat oven to 400°F (200°C).
Step 2: Prepare Chicken, Onions & Peppers
Slice chicken, peppers, and onion into even strips. You can use either regular bell peppers or mini bell peppers, both work great and add vibrant color to the dish.
Just be sure to remove the seeds and slice them thinly for even roasting.
Step 3: Fajita Seasoning
Add everything to a large baking sheet. Drizzle with oil and sprinkle all spices evenly over the top.
Toss to coat well so all ingredients are seasoned.
Step 4: Bake Chicken Fajitas
Spread into an even layer and bake for 30–35 minutes, stirring once halfway through. I cook on two different pans and keep the fajitas in the oven for the full 35 minutes to achieve extra crispy fajitas.
You can cook this recipe to your liking but keep in mind that the chicken should be cooked to an internal temperature of 165°F and the veggies should be roasted and tender.
