How to Make Sheet Pan Chicken Fajitas

Step 1: Prepare the chicken and vegetables

Start by slicing chicken breasts into thin strips, then cut bell peppers and onions into similar-sized slices to ensure even cooking.

Step 2: Mix the seasoning and coat

Combine olive oil with fajita seasoning and lime juice in a large bowl. Toss chicken and vegetables in the mixture until everything is evenly coated.

Step 3: Arrange on the sheet pan

Spread the coated chicken strips and vegetables in a single layer on a large rimmed baking sheet to allow roasting without steaming.

Step 4: Roast until cooked

Place the sheet pan in a preheated oven at 425°F (220°C) and roast for 20-25 minutes, stirring halfway through to evenly brown and cook the chicken thoroughly.

Step 5: Warm the tortillas

While the chicken and veggies finish roasting, warm your tortillas in a dry skillet or wrapped in foil in the oven to make them soft and pliable.

Step 6: Assemble and serve

Spoon the sizzling chicken and roasted vegetables into warm tortillas, then add your favorite toppings like salsa, guacamole, or sour cream, and enjoy.

Pro Tips for Making Sheet Pan Chicken Fajitas

• Uniform slicing: Cut chicken and veggies into similar sizes for even cooking.
• Use parchment paper: Line your sheet pan for easier cleanup and to prevent sticking.
• Don’t overcrowd the pan: Leave space between ingredients to let them roast rather than steam.
• Marinate briefly: Toss the chicken and vegetables in the seasoning mix at least 10 minutes before roasting to boost flavor.
• Check doneness: Ensure chicken reaches an internal temperature of 165°F (74°C) before serving.

FAQs

Can I use chicken thighs instead of chicken breasts?

Absolutely! Boneless, skinless chicken thighs work well and tend to be juicier and more flavorful, though they may require slightly longer cooking time.

Is this recipe gluten-free?

Yes, as long as you use gluten-free tortillas and check your seasoning blends for hidden gluten ingredients, this recipe is naturally gluten-free.

Can I make this recipe vegetarian?

Definitely! Swap the chicken for sturdy vegetables like mushrooms or tofu, and use vegetable broth or seasoning to enhance flavor.

What if I don’t have all the spices for the fajita seasoning?

You can improvise by mixing chili powder, paprika, garlic powder, onion powder, and cumin, or use a pre-made fajita or taco seasoning blend.

How do I keep the veggies crisp and not soggy?

Make sure to slice vegetables evenly and avoid overcrowding the pan so they roast and caramelize instead of steaming.
