Instructions

1. Prep the Ingredients
Slice chicken, bell peppers, and onion. Lightly grease a large sheet pan and spread the vegetables evenly across it. Place chicken strips on top.

2. Preheat Oven
Preheat your oven to 425°F (220°C).

3. Season Everything
In a small bowl, mix all fajita seasoning ingredients. Sprinkle most of it over the chicken and the rest over the vegetables. Add minced garlic and drizzle oil over the entire pan. Toss everything to coat and spread into an even layer.

4. Roast
Bake for 15–20 minutes, or until the chicken reaches 165°F internally and is fully cooked. Wrap the flour tortillas in foil and place them in the oven during the last 5 minutes to warm.

5. Finish & Serve
Remove the sheet pan from the oven. Squeeze fresh lime juice over the chicken and veggies, and sprinkle with chopped cilantro. Serve warm in tortillas with your favorite toppings.

Make-Ahead Tips & Storage

• Prep Ahead: Slice the chicken and veggies and mix the seasoning in advance. Store in the fridge until ready to cook.
• Leftovers: Store cooked fajitas in an airtight container in the fridge for up to 4 days.
• Reheat: Warm in a skillet or microwave. Great for wraps, rice bowls, or quesadillas.

Variations

• Spicier Fajitas: Add extra cayenne pepper or sliced jalapeños.
• Vegetarian Option: Use portobello mushrooms or tofu in place of chicken.
• Low-Carb: Serve in lettuce wraps or over cauliflower rice.
• Cheesy Version: Sprinkle shredded cheese over the fajitas and broil for 2–3 minutes.

What to Serve With Sheet Pan Chicken Fajitas

These fajitas are great on their own but even better with:

• Chips and salsa or guacamole
• Corn salad or grilled street corn (elote)
