How to Make Sheet Pan Chicken Fajitas

This method is easy, fast, and perfect for beginners.

Step 1. Prep the Chicken and Vegetables

Slice chicken breasts into thin strips. Cut bell peppers and onions into uniform slices for even cooking.

Place everything on a large sheet pan.

Step 2. Season Generously

Drizzle with olive oil.

Sprinkle fajita seasoning mixture over the chicken and vegetables.

Use tongs or clean hands to toss until everything is well coated.

Spread evenly across the pan for proper roasting.

Step 3. Roast Until Tender

Bake at 400°F (205°C) for 20–25 minutes, or until the chicken is cooked through and vegetables are tender.

For charred edges that mimic restaurant-style fajitas, broil for the last 2–3 minutes.

Step 4. Finish with Fresh Lime

Remove from the oven and squeeze fresh lime juice over the top.

Toss lightly to coat.

This brightens the dish and enhances the spices.

Step 5. Serve Warm

Load chicken and vegetables into warm tortillas and top with your favorite garnishes.

Serve with:

• Avocado or guacamole

• Sour cream

• Pico de gallo

• Cheese

• Cilantro

• Jalapeños

 

Why Oven-Roasting Works So Well for Fajitas

Roasting at high heat caramelizes the vegetables and allows the chicken to cook quickly while staying tender. The dry heat also helps the spices become more fragrant, adding depth and warmth to the overall dish.

The sheet pan method also ensures even cooking, eliminating the need for constant stirring or grilling.
