Ingredients

Makes one 9x13 inch casserole · serves 6

Main

  • 2 lb chicken breast, cooked and shredded
  • 2 cups long grain white rice, cooked
  • 2 cups bell peppers, diced

Topping

  • 2 cups shredded mozzarella cheese

Sauce

  • 2 tbsp fajita seasoning
Contains: milk

Why this recipe works

The method of combining all primary ingredients into a single bowl before baking ensures that the fajita seasoning is perfectly distributed throughout the mixture.

This technique prevents pockets of unseasoned rice or chicken, creating a balanced flavor profile in every scoop. The ingredients work together to keep the chicken and rice moist during the baking process while preventing the rice from drying out in the oven's heat.

Baking the casserole in a single dish allows the flavors to meld together effectively while the cheese creates a protective layer that keeps the interior succulent. The high heat of the oven melts the cheese into a luscious, stretchy topping that adds a contrasting texture to the tender filling. This approach minimizes the number of pots and pans needed, making the cleanup process as straightforward as the preparation itself.

Notes and substitutions

For the best results, use a high-quality shredded mozzarella that melts well. If you prefer a more complex flavor, you can blend the mozzarella with a small amount of Monterey Jack or cheddar.

Ensure the chicken is shredded into manageable pieces to allow for a better mouthfeel, as large chunks can make the casserole difficult to serve evenly. If the chicken is too dry, add a splash of chicken broth to the mixture to restore moisture.

The equipment required is minimal, consisting primarily of a reliable 9x13 inch baking dish and a sturdy mixing bowl. If you find the casserole is browning too quickly, you can cover it with aluminum foil for the first half of the cooking time.

The choice of bell peppers can also be customized; using a mix of red, yellow, and green peppers not only improves the visual appeal of the dish but also adds a subtle variety of sweetness to the final flavor.
