Cook The Chicken 

Cut the chicken breast into 1-inch cubes and season them with onion powder, garlic powder, salt, and pepper.

Heat the olive oil in a large skillet over medium-high heat and cook the chicken bites for about 5 minutes on each side until golden brown.

Prepare The Broccoli

While the chicken is cooking, cut the broccoli into bite-size florets.

Assemble The Casserole

Spread ½ cup of keto alfredo sauce on the bottom of a casserole dish. Then add the cooked chicken and broccoli florets.

Top with the rest of the alfredo sauce and mix until everything is well combined.

Sprinkle the mozzarella cheese on top of the casserole.

Bake The Casserole

Garnish with fresh parsley, and enjoy.

Tips For Chicken Alfredo Casserole

• Ensure you don’t overbake the casserole because the chicken will dry out, and the broccoli will become mushy.
• You can add other vegetables to the casserole, like cauliflower or bell peppers.
• Add one tbsp of red pepper chili flakes for a spicy chicken alfredo casserole.
• I like to use mozzarella cheese in this recipe, but cheddar cheese or a cheese mix works amazing.
• For a golden and crispy topping, sprinkle some extra Parmesan cheese and breadcrumbs on top of the casserole before baking.

Variations

• Spinach and Artichoke: Add chopped spinach and canned artichoke hearts to the casserole.
• Buffalo Chicken: Use buffalo sauce and shredded chicken to add a spicy kick.
• Sun-Dried Tomato: Add chopped sun-dried tomatoes to the casserole.
