A vibrant and easy-to-make Sheet Pan Chicken Fajitas recipe featuring tender strips of chicken breast and colorful bell peppers baked together with flavorful spices. Perfect for a quick weeknight dinner that requires minimal cleanup.
Preheat Oven: Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper to prevent sticking and facilitate easy cleanup.
Prepare Ingredients: Slice the chicken breasts into thin strips. Chop the red and green bell peppers and the large onion into bite-sized pieces to ensure even cooking.
Toss with Seasonings: In a large bowl, combine the sliced chicken, olive oil, cumin, chili powder, garlic powder, salt, and pepper. Toss everything thoroughly to coat the chicken and vegetables evenly with the spices and oil.
Arrange on Sheet Pan: Spread the seasoned chicken and vegetables evenly over the prepared baking sheet in a single layer to ensure proper roasting.
Bake: Place the sheet pan in the preheated oven and bake for 20-25 minutes or until the chicken is cooked through and has a nice golden brown color, and the vegetables are tender.
Finish with Lime Juice: Once out of the oven, drizzle the lime juice over the fajitas to add a fresh, tangy brightness before serving.
Notes
For added flavor, let the chicken and vegetables marinate in the seasoning mix for 15-30 minutes before baking.
Serve with warm tortillas, guacamole, sour cream, or salsa for a complete fajita meal.
You can substitute chicken breasts with chicken thighs for juicier results.
Adjust spice levels by adding more chili powder or a pinch of cayenne pepper if desired.
If you don’t have parchment paper, lightly grease the baking sheet instead.
