Instructions:
- Preheat your oven to 400°F (200°C) and lightly grease a baking dish.
- Season chicken breasts on both sides with cumin, chili powder, garlic, paprika, salt, and pepper.
- Set aside some of the spices for later.
- Place chicken breasts in the prepared baking dish and drizzle with oil.
- Top with bell peppers and onions, and sprinkle with remaining fajita seasonings. Finish with shredded mozzarella cheese.
- Bake the fajita chicken casserole for 20-30 minutes (depending on the thickness), or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C). You can broil the casserole for 2 minutes in the end to crisp up the top if desired.
- Serve immediately over cauliflower rice, steamed vegetables, zucchini noodles, or on its own.
Enjoy!
