• 1 teaspoon chili powder

• 1 teaspoon ground cumin

• 1/2 teaspoon garlic powder

• 1/2 teaspoon onion powder

• Salt and black pepper, to taste

• 1 red bell pepper, diced

• 1 green bell pepper, diced

• 1 cup shredded cheddar cheese

• 1 cup shredded mozzarella cheese

Instructions

Follow these simple steps for perfect results every time:

Step 1: Preheat the Oven

• Preheat your oven to 375°F (190°C).

• Lightly grease a baking dish with nonstick spray or a little olive oil.

Step 2: Prepare the Chicken

• Arrange the chicken breasts in a single layer in the baking dish.

• Drizzle 1 tablespoon of olive oil evenly over the chicken.

Step 3: Mix the Fajita Seasoning

• In a small bowl, combine:

  • 1 teaspoon chili powder

  • 1 teaspoon cumin

  • 1/2 teaspoon garlic powder

  • 1/2 teaspoon onion powder

  • Salt and pepper to taste

• Stir until all spices are well blended.

Step 4: Season the Chicken

• Sprinkle the spice mixture evenly over the chicken breasts, gently patting it down so it sticks to the olive oil.

Step 5: Add the Bell Peppers

• Scatter the diced red and green bell peppers over and around the chicken.

Step 6: Bake Covered

• Cover the baking dish with aluminum foil.

• Bake in the preheated oven for 25 minutes to keep the chicken moist.

Step 7: Add Cheese and Bake Again

• Carefully remove the foil.

• Sprinkle 1 cup shredded cheddar cheese and 1 cup shredded mozzarella cheese evenly over the chicken and peppers.

• Return the dish to the oven, uncovered, and bake for an additional 10–15 minutes, or until:

  • The cheese is melted and bubbly.

  • The chicken reaches an internal temperature of 165°F (74°C).

Step 8: Optional Broil

• For a crispy, golden cheese topping, set your oven to broil.

• Broil for 2–3 minutes, watching closely to prevent burning.

Step 9: Rest and Serve

• Remove the baking dish from the oven.

• Let it rest for 5 minutes before serving.

• Garnish with fresh cilantro or parsley, if desired.

• Spicy Kick:

  • Add sliced jalapeños or a pinch of cayenne pepper to the spice mix.
