How To Make the Sheet Pan Chicken Fajitas

Step 1: Preheat and Prep

Preheat your oven to 400°F. Line a large sheet pan with parchment paper or lightly oil it for easy cleanup.

Step 2: Slice Everything

Thinly slice the chicken, bell peppers, and red onion. Uniform size helps everything cook evenly.

Step 3: Season Well

In a large bowl, combine the sliced chicken and veggies with olive oil, chili powder, cumin, paprika, garlic powder, salt, and pepper. Toss until everything is coated in the spice blend.

Step 4: Bake to Perfection

Spread the mixture evenly on your sheet pan. Bake for 20–25 minutes, stirring halfway through, until the chicken is cooked through and the veggies are tender with charred edges.

Step 5: Add a Zesty Finish

Squeeze fresh lime juice over the hot fajitas right after they come out of the oven.

Step 6: Serve It Up

Serve with warm tortillas and your favorite toppings like sour cream, salsa, guacamole, or shredded cheese.
