  • Veggie Power-Up: Toss in extra vegetables like corn, zucchini, or spinach to boost nutrition and add colorful texture. Roast these veggies beforehand for a more concentrated flavor profile.

Ingredients

Scale
  • 4 cups (950 mL) shredded cooked chicken (about 2 large breasts)
  • 1 (8 oz/226 g) package shredded Mexican blend cheese (about 2 cups)
  • 2 cups (400 g) instant rice

  • 1 ½ cups (360 mL) chicken broth
  • 1 (1.12 oz/32 g) packet fajita seasoning (McCormick)

Instructions

  1. Prepare Oven and Dish: Preheat to 350°F and lightly spray a 9×13 inch baking dish with nonstick coating to ensure easy release.
  2. Create Flavor Base: In a large mixing bowl, combine shredded chicken, raw rice, cream of chicken soup, sour cream, chopped onions, diced bell peppers, tomatoes with chilies, chicken broth, and fajita seasoning, mixing until ingredients are fully integrated and evenly distributed.
  3. Cheese Integration: Fold approximately half of the shredded cheese into the mixture, ensuring a uniform distribution that will provide pockets of melted goodness throughout the casserole.

  5. Initial Baking Phase: Place in preheated oven and bake for 35-45 minutes, allowing rice to become tender and absorb the flavorful liquid while maintaining a moist texture.
  6. Final Cheese Topping: Remove foil, sprinkle remaining cheese over the surface, and return to oven for 3-5 minutes until cheese melts into a golden, bubbling layer.
  7. Rest and Serve: Allow casserole to rest for 5 minutes, enabling ingredients to set and flavors to meld before serving a comforting, cheesy dish.
