How to Make Sheet Pan Chicken Fajitas

Get ready to turn these simple ingredients into a mouthwatering dish in just six easy steps!

1. Preheat Your Oven

Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper or grease lightly.

2. Season Chicken and Veggies

Combine the sliced chicken, bell peppers, and onion in a large mixing bowl.

Drizzle with olive oil, then sprinkle with chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, and pepper. Toss everything until evenly coated.

3. Arrange on the Sheet Pan

Spread the seasoned chicken and vegetables in a single layer on your sheet pan for even cooking.

4. Bake

Roast in the oven for 20–25 minutes, stirring halfway through. The chicken should reach an internal temperature of 165°F (74°C) when done.

5. Add Lime and Garnish

Once removed from the oven, squeeze fresh lime juice over the fajitas and sprinkle them with chopped cilantro for an extra burst of flavor.

6. Serve and Enjoy

Serve hot with your favorite tortillas and toppings like guacamole, sour cream, or salsa.

Tips and Tricks for Perfect Fajitas

• Uniform Slicing: Slice chicken and veggies evenly for consistent cooking.
• Avoid Overcrowding: Spread ingredients evenly in a single layer; overcrowding can lead to steaming instead of roasting.
• Prep Ahead: Marinate the chicken and veggies the night before for even more flavor.

Storing and Reheating Leftovers

Storage

• Place leftovers in an airtight container and refrigerate for up to 3 days.

Reheating

• Reheat in a skillet over medium heat for crispy edges, or microwave in 30-second intervals until warmed through.

Freezing

• Freeze cooked fajitas in portions for up to 2 months. Defrost in the fridge overnight before reheating.

Common Mistakes to Avoid

• Overcooking the Chicken: Use a meat thermometer to check for 165°F (74°C). Overcooked chicken can turn dry.
• Skipping the Lime: Fresh lime juice enhances the flavors and balances the spices.
• Crowding the Pan: Overcrowding leads to steaming rather than roasting, resulting in soggy veggies.
