Ingredients

• 1.5 pounds Boneless, skinless chicken breasts
• 3 medium Bell peppers (red, yellow, green, or a mix)
• 1 large Yellow onion
• 2 tablespoons Olive oil
• 2 tablespoons Fajita seasoning
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 2 cups Cooked white or brown rice
• 2 cups Shredded Mexican blend cheese
• 1 cup Sour cream
• 2 tablespoons Cilantro (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish and set aside.

Step 2

Cut the chicken breasts into thin strips, about 1/2-inch wide. Slice the bell peppers and onion into thin strips as well.

Step 3

Heat a large skillet over medium-high heat and add 2 tablespoons of olive oil. Once hot, add the chicken strips and cook for 5–6 minutes, or until the chicken is no longer pink on the outside.

Step 4

Add the sliced bell peppers and onions to the skillet with the chicken. Sprinkle in the fajita seasoning, salt, and black pepper. Stir and sauté for another 5–7 minutes until the vegetables are slightly softened and the chicken is fully cooked.

Step 5

Spread the cooked rice evenly across the bottom of the prepared casserole dish.

Step 6

Layer the chicken and vegetable mixture on top of the rice, spreading it out evenly.

Step 7

In a small bowl, mix the sour cream with 1 cup of the shredded cheese. Spread this mixture evenly over the chicken and vegetables in the casserole dish.

Step 8

Sprinkle the remaining 1 cup of cheese over the top of the casserole.

Step 9

Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. Then, remove the foil and bake for an additional 10–15 minutes, or until the cheese is melted and bubbly.

Step 10

Remove the casserole from the oven and let it rest for 5 minutes before serving.

Step 11

Garnish with chopped cilantro, if desired, and serve warm. Enjoy!
