MEAL PREP TIP: During your Sunday meal prep, cook this entire casserole IN ADVANCE. Then during the week, you can dish it out for lunch or dinner without having to cook again! You can do this up to five days in advance. But you might want to double the recipe so that you have enough for leftovers for lunch!
Need an Easy Button? Are you short on time and need a shortcut to make this recipe easier? Cook the chicken in the Instant Pot. Instead of having to stand over the sauté pan and stir the chicken, just set the Instant Pot to 8 minutes and walk away!

Cheesy Chicken Fajita Casserole
- 4 chicken breasts, boneless and skinless cut into 1" pieces
- 2 bell peppers sliced or chopped
- 1/2 onion sliced or chopped
- 1 packet fajita seasoning (or taco seasoning)
- 1 cup low fat sour cream
- 4 oz low fat cream cheese
- 2 cups low fat cheddar cheese shredded
- Preheat the oven to 350F.
- Sauté the chicken until cooked through. (For an easier fix-it-and-forget-it open, cook the chicken in an Instant Pot for 8 minutes.)
- Remove the chicken from the pan and set aside. Sauté the onions and peppers in the same pan until tender.
- Add the chicken, peppers, and onions to a baking dish. Stir in sour cream, cream cheese, and fajita seasoning. Cover with shredded cheddar cheese. (If you are using a oven safe sauté pan, you can simply add everything back to the pan and put it in the oven.)
- Bake for approximately 20 minutes or until the cheese is melted.
