Ingredients
2 large chicken breasts, skinless, boneless, cut into cubes
2 bell peppers (red, green, or yellow), seeded and sliced into strips
1 medium onion, minced
8 oz (225 g) cream cheese, softened
1/3 cup tomato sauce (marinara, crushed tomatoes, or your favorite)
1/4 cup chicken stock (or substitute water + 1 teaspoon instant bouillon)
1 packet fajita seasoning (or homemade blend)
1/2 teaspoon salt and black pepper
1 tablespoon vegetable oil
1 cup shredded mozzarella cheese (or Pepper Jack, Monterey Jack, cheddar)
Fresh chopped cilantro or parsley for garnish
Instructions
Preheat your oven to 400°F (200°C). Lightly oil a baking dish.
In a bowl, beat together the softened cream cheese, tomato sauce, chicken stock, half the fajita seasoning, salt, and pepper until smooth.
Add the cubed chicken to the prepared baking dish. Sprinkle with the remaining fajita seasoning and toss to coat evenly.
Pour the creamy fajita mixture over the chicken and stir well to coat all pieces.
Arrange bell pepper strips and minced onion evenly over the top.
Sprinkle shredded cheese generously over the veggies.
Bake for 15-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Optional: Broil for 2 minutes at the end for a golden, crispy cheese topping.
Serve hot over cauliflower rice, steamed veggies, zucchini noodles, or enjoy as-is. Garnish with fresh cilantro or parsley.
Notes
DIY Fajita Seasoning: Mix 1 teaspoon chili powder, ½ teaspoon paprika, ½ teaspoon cumin, ¼ teaspoon garlic powder, ¼ teaspoon onion powder, and a pinch of cayenne.
Swap chicken breasts for chicken thighs for extra juiciness.
Try different cheeses for a fun twist—Pepper Jack for heat, cheddar for extra richness.
Leftovers taste even better the next day and make delicious wraps!
