Ingredients

  • 2 large chicken breasts, sliced into thin strips

  • 3 bell peppers, sliced

  • 1 large yellow onion, sliced

  • 2 tablespoons olive oil

Fajita Seasoning

  • 2 teaspoons chili powder

  • 1/2 tablespoon cumin

  • 2 teaspoons garlic powder

  • 1 teaspoon onion powder

  • 1 teaspoon paprika

  • 1/2 teaspoon black pepper

  • 2 teaspoons salt

Optional Topping

  • Chopped fresh cilantro

How to Make Sheet Pan Chicken Fajitas

1. Prepare the Chicken and Vegetables

Preheat your oven to 400°F.

Add the sliced chicken, bell peppers, onion, and olive oil to a large mixing bowl.

Add all of the fajita seasoning and toss until the chicken and vegetables are evenly coated.

2. Roast the Fajitas

Spread the chicken and vegetables onto a large baking sheet in a single, even layer.

Bake for 10 minutes.

Carefully remove the baking sheet from the oven and use a spatula to stir the chicken and vegetables, spreading everything back into an even layer.

Return the pan to the oven and bake for another 5 minutes.

3. Broil for Caramelized Edges

Switch the oven to High Broil and broil for 2–3 minutes, watching closely, until the chicken is cooked through and the peppers and onions have lightly charred around the edges.

The broiling step is what gives these fajitas those delicious caramelized edges and that classic sizzling fajita flavor.

4. Serve

Serve immediately over Mexican rice or in warm flour or corn tortillas.

Top with your favorite fajita toppings and a squeeze of fresh lime juice.

Tips for the Best Chicken Fajitas

  • Slice the chicken evenly. Thin, uniform pieces will cook more quickly and evenly.

  • Don't overcrowd the pan. Spread everything into a single layer so the chicken and vegetables roast instead of steam.

  • Don't skip the broiling step. A few minutes under high broil creates those delicious browned and slightly charred edges.

  • Use a large baking sheet. If your pan is too crowded, divide everything between two pans.

  • Warm your tortillas. Warm tortillas are softer and make the fajitas easier to assemble.

  • Finish with fresh lime. A squeeze of lime right before serving brightens all of the flavors.

Frequently Asked Questions

Can I make these ahead of time?

Yes! You can slice the chicken and vegetables ahead of time and store them separately in the refrigerator. Toss everything with the oil and seasoning just before baking.

You can also cook the entire recipe ahead of time and reheat it for meal prep.

Can I double this recipe?

Absolutely! This recipe doubles easily. For the best results, use two sheet pans so the chicken and vegetables have plenty of room to roast instead of steam.

Can I use different vegetables?

Definitely! Mushrooms, poblano peppers, zucchini, or sliced jalapeños are all delicious additions.

Can I use chicken thighs?

Yes! Boneless, skinless chicken thighs are a great substitute for chicken breasts. Slice them into thin, even strips and cook until they reach an internal temperature of 165°F.

How do I store leftovers?

Store leftover chicken fajitas in an airtight container in the refrigerator for up to 4 days.

Reheat in a skillet, microwave, or oven until warmed through.
