Juicy chicken thighs, colorful bell peppers, and onions roast together on one pan in this easy Sheet Pan Chicken Fajitas recipe, perfect for serving with homemade guacamole and warm tortillas.
Slice the chicken, bell peppers, and red onion into thin strips. Spread everything evenly onto a large baking sheet. Lightly spray with avocado oil, then season generously with the taco seasoning, tossing everything together until evenly coated.
Bake for 20-25 minutes, or until the chicken is fully cooked and the vegetables are tender with lightly browned edges.
While the fajitas bake, make the guacamole by mashing the avocados with the lime juice, diced red onion, salt, pepper, and garlic powder until well combined.
Warm the tortillas in a dry skillet over medium-high heat for about 30 seconds per side, or until soft and lightly toasted.
Fill each tortilla with the chicken and vegetable mixture, then top with the guacamole, salsa, and any of your favorite toppings.
