Ingredients You’ll Need

The magic of this creamy low carb chicken casserole comes from a few simple, high-quality ingredients. Here’s what you’ll need:

Chicken: Cooked and shredded chicken breast is the star. A rotisserie chicken works as a fantastic time-saver!
Broccoli: Fresh, crisp broccoli florets add texture, nutrients, and a vibrant color.
Cream Cheese: This is the secret to an ultra-creamy, rich sauce. Make sure it’s softened for easy mixing.
Heavy Cream: Thins the sauce to the perfect consistency, adding to the luxurious feel.
Cheddar Cheese: We use sharp cheddar for its bold flavor, both in the sauce and on top for that irresistible golden crust.
Seasonings: Garlic powder, onion powder, salt, and black pepper create a deep, savory flavor base.

Step-by-Step Instructions

Making this cheesy keto chicken bake is as simple as mix, pour, and bake. Follow these steps for perfect results every time.

Preheat and Prep: First, preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish. This ensures nothing sticks and cleanup is a breeze.
Make the Creamy Sauce: In a large bowl, combine the softened cream cheese, heavy cream, half of the shredded cheddar, garlic powder, onion powder, salt, and pepper. Mix until everything is smooth and well-incorporated.
Combine Ingredients: Add the shredded chicken and broccoli florets to the bowl with the sauce. Gently stir until the chicken and broccoli are fully coated in the creamy mixture.
Assemble the Casserole: Pour the mixture into your prepared baking dish and spread it into an even layer.
Top and Bake: Sprinkle the remaining shredded cheddar cheese evenly over the top. Bake for 20-25 minutes, or until the casserole is hot and bubbly and the cheese on top is melted and golden brown. For a crispier top, you can broil it for the last 1-2 minutes—just watch it closely!
Rest and Serve: Let the casserole rest for 5-10 minutes before serving. This helps it set up, making it easier to serve.

Tips for a Perfect Casserole

While this recipe is simple, a few expert tips can take it from great to absolutely perfect. For a similar dish with a different flavor profile, check out our Chicken Cordon Bleu Casserole.

Use Softened Cream Cheese: Ensure your cream cheese is at room temperature. It will mix into a lump-free, silky-smooth sauce.
Don’t Overcook the Broccoli: The broccoli will cook in the oven, so start with fresh, raw florets to ensure they are tender-crisp, not mushy.
Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can make the sauce gritty. Shredding a block of cheddar will result in a much smoother, meltier sauce.

Variations and Substitutions

Spice It Up: Add a pinch of red pepper flakes or a dash of hot sauce to the cream cheese mixture for a little heat.
Change the Cheese: Try a blend of Monterey Jack and cheddar, or add some Gruyère for a nutty flavor.
