Description

A flavorful Chicken Fajita Casserole combining tender chicken, sautéed bell peppers, creamy cheeses, and seasoned rice, baked to bubbly perfection. This easy, one-dish meal brings the bold flavors of fajitas in a comforting casserole ideal for weeknight dinners.


Ingredients

Scale

Chicken and Seasoning

  • 1 1/2 pounds chicken breast cut into bite-sized pieces
  • 3 tablespoons olive oil divided
  • 1 packet fajita seasoning
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper

Vegetables

  • 1 red bell pepper diced
  • 1 green bell pepper diced
  • 1 yellow bell pepper diced
  • 1 yellow onion diced

Dairy and Rice

  • 1 cup sour cream
  • 1 8-ounce block cream cheese softened
  • 1 cup instant rice (Minute Rice)
  • 1 1/4 cups chicken stock
  • 2 cups shredded Colby Jack cheese divided

Instructions

  1. Preheat Oven: Preheat the oven to 375°F (190°C) to prepare for baking the casserole.
  2. Season Chicken: In a large bowl, coat the chicken pieces with 1 tablespoon olive oil and the fajita seasoning, tossing evenly to ensure full coverage.
  3. Cook Chicken: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Cook the seasoned chicken pieces for 5-7 minutes until browned and cooked through. Remove from the pan and set aside.
  4. Sauté Vegetables: Add the remaining 1 tablespoon olive oil to the skillet. Sauté diced red, green, yellow bell peppers and yellow onion for 5-6 minutes until slightly tender. Remove from heat.
  5. Mix Casserole Base: In a large bowl, combine softened cream cheese and sour cream until smooth. Stir in chicken stock, instant rice, 1 cup shredded Colby Jack cheese, cooked chicken, sautéed vegetables, salt, and black pepper. Mix thoroughly; the mixture will be liquidy but will thicken during baking.
  6. Assemble: Lightly grease a 9×13-inch baking dish and pour the mixture in, spreading evenly. Top with the remaining 1 cup shredded Colby Jack cheese and cover tightly with aluminum foil.
  7. Bake: Bake covered for 20 minutes. Remove foil and bake an additional 15 minutes until cheese is melted and bubbly.
  8. Rest and Serve: Let the casserole sit for 5 minutes to set before serving. Enjoy your flavorful chicken fajita casserole!

Notes

  • Use instant rice for quicker cooking and a tender texture; regular rice would require longer cooking time and more liquid.
  • You can substitute Colby Jack cheese with Monterey Jack or a Mexican cheese blend for different flavor profiles.
  • For extra heat, add diced jalapeños with the bell peppers during sautéing.
  • If preferred, use low-fat sour cream and cream cheese to reduce fat content.
  • Covering the casserole tightly during the first baking stage helps the rice cook properly in the steam.
  • Allowing the casserole to rest before serving helps it to firm up for easier slicing and serving.
