Scale

2 pounds boneless, skinless chicken breasts, sliced
3 bell peppers (red, yellow, green), sliced
1 large onion, sliced
2 tablespoons olive oil
1 packet fajita seasoning (or homemade blend)
1 teaspoon chili powder
½ teaspoon smoked paprika

1 cup sour cream
1 can (10 oz) diced tomatoes with green chilies, drained
1½ cups shredded Mexican blend cheese
½ cup shredded mozzarella (optional)

Instructions

Step 1:

Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

Step 2:

In a large bowl, toss sliced chicken with olive oil, fajita seasoning, chili powder, paprika, salt, and black pepper until evenly coated.

Step 3:

Spread the seasoned chicken evenly in the baking dish. Top with sliced bell peppers and onions.

Step 4:

In a separate bowl, mix sour cream and drained diced tomatoes. Spoon this mixture evenly over the chicken and vegetables.

Sprinkle shredded cheese over the top. Bake uncovered for 30–35 minutes, until chicken is cooked through and cheese is bubbly and golden.

Notes

Slice chicken evenly to ensure uniform cooking. If pieces are too thick, they may require additional baking time.
