Ingredient Breakdown

Cooked Chicken

Shredded or diced chicken forms the protein base of the dish. Rotisserie chicken works well and saves time. Chicken breast keeps the casserole light and lean.

Broccoli Florets

Broccoli adds nutrients, color and texture. Its mild flavor blends beautifully with the sauce and cheese. You can use fresh or frozen broccoli.

Cream Cheese

Cream cheese provides the rich, creamy base. It melts into the sauce and gives the casserole its signature comforting texture.

Cheddar Cheese

Shredded cheddar cheese melts on top and inside the casserole, creating a cheesy, golden crust. Use sharp cheddar for stronger flavor.

Greek Yogurt or Sour Cream

Greek yogurt adds protein and creates a creamy sauce without heaviness. Sour cream works as well for richer flavor.

Garlic Powder and Onion Powder

These seasonings enhance the flavor without adding carbs. They blend smoothly into the sauce.

Chicken Broth

Used to thin the sauce while adding depth of flavor.

Cooked Bacon (Optional)

Adds smoky crunch and extra flavor. Totally optional but highly recommended for additional richness.

Optional Add Ins
