Ingredients

For the Chicken

• 4 boneless, skinless chicken breasts
• 2 tbsp olive oil
• 1½ tsp chili powder
• 1 tsp paprika
• 1 tsp smoked paprika
• 1 tsp ground cumin
• ½ tsp garlic powder
• ½ tsp onion powder
• ½ tsp dried oregano
• ½ tsp salt
• ¼ tsp black pepper
• ¼ tsp cayenne pepper, optional

For the Fajita Vegetables

• 1 large red bell pepper, sliced
• 1 large green bell pepper, sliced
• 1 medium yellow onion, sliced
• 2 cloves garlic, minced
• 1 tbsp olive oil
• ½ tsp salt
• ¼ tsp black pepper

For the Cheese Topping

• 1 cup shredded Monterey Jack cheese
• 1 cup shredded cheddar cheese
• ½ cup shredded mozzarella cheese

For Serving

• Fresh cilantro, chopped
• Lime wedges
• Sliced jalapeños, optional
• Sour cream, optional
• Avocado or guacamole, optional

Directions

1. Prepare the oven

Preheat your oven to 400°F (200°C).

Lightly grease a large baking dish or oven-safe skillet.

2. Prepare the fajita seasoning

In a small bowl, combine the chili powder, paprika, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, black pepper, and cayenne pepper.

Mix well.

3. Season the chicken

Pat the chicken breasts dry with paper towels.

Rub each chicken breast with olive oil, then generously coat both sides with the fajita seasoning.

For thicker chicken breasts, gently pound them to an even thickness. This helps them cook evenly.

4. Prepare the vegetables

Place the sliced bell peppers and onions in a large bowl.

Add the olive oil, minced garlic, salt, and black pepper.

Toss until the vegetables are evenly coated.

Spread them around the chicken in the prepared baking dish.

5. Bake the chicken

Place the seasoned chicken breasts in the center of the baking dish.

Bake uncovered for approximately 20–25 minutes, depending on the thickness of the chicken.

The chicken should reach an internal temperature of 165°F (74°C) at the thickest part.

6. Add the cheese

Remove the baking dish from the oven.

Generously sprinkle the cheddar, Monterey Jack, and mozzarella over the chicken and vegetables.

Return the dish to the oven and bake for another 5–7 minutes, until the cheese is completely melted and bubbling.

For a golden, slightly browned cheese topping, switch the oven to broil for 1–2 minutes, watching carefully.

7. Rest and garnish

Remove the chicken from the oven and let it rest for 5 minutes.

Sprinkle with fresh chopped cilantro and serve with lime wedges.

Tips for Juicy Fajita Chicken

• Don’t overcook the chicken. Use a meat thermometer for the most reliable result.
• Pound thick chicken breasts to an even thickness.
• Allow the chicken to rest before slicing so the juices redistribute.
• For extra flavor, marinate the seasoned chicken for 30 minutes to 4 hours before baking.
• Use freshly shredded cheese for the smoothest melting.
• Add sliced mushrooms or zucchini for extra vegetables.

Make It Extra Creamy

For a creamy version, spread 2–3 tablespoons of cream cheese or sour cream over each chicken breast before adding the shredded cheese. The result is rich, creamy, and incredibly satisfying.
