Ingredients for the Low Carb Chicken Casserole

To make this deliciously creamy bake, you’ll only need a few pantry and fridge staples. Every ingredient plays a role in making this dish rich, flavorful, and low in carbs.

Cooked Chicken – Use shredded or cubed chicken breast or thigh, seasoned and cooked.

Cream Cheese – Brings the creamy texture and helps bind everything together.

Sour Cream – Adds tang and lightens up the cheese blend.

Shredded Cheddar Cheese – Melts beautifully and gives that gooey cheesy goodness.

Garlic Powder – Infuses the casserole with subtle, savory flavor.

Onion Powder – Adds depth and a little sweetness to balance the tangy ingredients.

Salt and Pepper – Essential for balancing all the flavors.

Steamed Broccoli or Cauliflower – Optional but perfect for adding nutrients and crunch.

How To Make the Low Carb Chicken Casserole

Step 1: Preheat and Prep

Preheat your oven to 375°F. Lightly grease a casserole dish with olive oil or butter.

Step 2: Mix the Filling

In a large mixing bowl, combine the cooked chicken, cream cheese, sour cream, garlic powder, onion powder, salt, pepper, and half of the shredded cheddar cheese. Stir until everything is evenly coated and creamy.

Step 3: Add the Veggies

If you’re including broccoli or cauliflower, fold it into the chicken mixture until well distributed.

Step 4: Assemble the Casserole

Transfer the mixture to the greased casserole dish. Spread it out evenly and top with the remaining shredded cheese.

Step 5: Bake to Perfection

Bake uncovered for 20-25 minutes, or until the cheese is melted and bubbly with a light golden crust on top.

Step 6: Cool and Serve

Let it rest for a few minutes before serving to allow the casserole to set. This also enhances the flavors.
