Ingredients

Scale

Protein & Dairy

  • 3 cups Shredded Cooked Chicken (rotisserie recommended)
  • 1 can (10.5 oz) Cream of Chicken Soup (can substitute with cream of mushroom soup)
  • 1 cup Sour Cream (low-fat options available)
  • 2 cups Shredded Mexican Blend Cheese (sharp cheddar or pepper jack works well)

Grains & Legumes

  • 1 cup Instant Rice (uncooked)

Vegetables

  • 16 oz Frozen Diced Onion and Bell Pepper Blend (fresh can be used for extra crunch)
  • 1 can (10 oz) Diced Tomatoes with Chilies (undrained for saucier casserole)

Liquids & Seasoning

  • 1 cup Chicken Broth (low-sodium recommended)
  • 2 tbsp Fajita Seasoning (McCormick’s recommended)

Instructions

  1. Preheat the oven: Set your oven temperature to 350°F (175°C) and prepare a 9×13 inch baking dish by spraying it with nonstick cooking spray to prevent sticking.
  2. Combine ingredients: In a large mixing bowl, thoroughly mix the shredded cooked chicken, uncooked instant rice, cream of chicken soup, sour cream, frozen diced onion and bell pepper blend, undrained diced tomatoes with chilies, chicken broth, and fajita seasoning until evenly combined.
  3. Transfer to baking dish: Pour the mixture into the prepared baking dish and spread it out evenly to ensure uniform cooking.
  4. Bake covered: Cover the baking dish tightly with aluminum foil and bake for 35 to 45 minutes. This allows the rice to absorb liquid and become tender while the flavors meld together.
  5. Add cheese and continue baking: Remove the foil and sprinkle the shredded Mexican blend cheese evenly over the top. Return the dish to the oven, uncovered, and bake for an additional 5 to 10 minutes until the cheese is fully melted and bubbly.
  6. Serve: Remove from the oven and let the casserole sit for a few minutes before serving warm. Enjoy your hearty and cheesy chicken fajita casserole!

Notes

  • Using rotisserie chicken saves time and adds flavor.
  • Fresh diced onion and bell pepper can be substituted for frozen for a crisper texture.
  • Low-fat sour cream and low-sodium chicken broth options make this dish lighter.
  • If cream of chicken soup is unavailable, cream of mushroom soup is a good substitute.
  • For spicier casserole, consider using pepper jack cheese and additional fajita seasoning.
  • Allow casserole to rest for 5-10 minutes after baking to set for easier serving.
