Step 2: Mix the Ingredients

  • In a large bowl, combine the shredded cooked chicken, instant rice, cream of chicken soup, sour cream, frozen onion and bell pepper blend, diced tomatoes with chilies, chicken broth, fajita seasoning, and about half of the shredded Mexican blend cheese. Mix until all the ingredients are well combined.

Tips and Shortcuts

Recipe Variations

Pair your Fajita Chicken Casserole with a crisp, refreshing salad, and a side of guacamole and sour cream for a complete Mexican-inspired meal. As for drinks, consider serving it with a cold glass of iced tea or a margarita for a fiesta-inspired dinner.
