Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. Prepare 1/2 cup yellow onion, finely diced, and 2 cloves garlic, minced. Ensure 4 cups broccoli florets are ready for assembly.

In a large skillet over medium heat, sauté the 1/2 cup yellow onion until softened, about 3-5 minutes. Add the 2 cloves garlic, minced, and cook for another minute until fragrant, being careful not to burn.

Reduce heat to low. Add 8 oz cream cheese, softened, 1/2 cup heavy cream, 1/2 cup chicken broth, 1/4 cup sour cream, and 1 tbsp Dijon mustard to the skillet. Whisk until smooth. Stir in 1 tsp garlic powder, 1/2 tsp dried thyme, and season with salt and black pepper to taste. This forms the heart of your Creamy Low Carb Chicken Casserole.

Remove the skillet from heat. Fold in 2 lbs cooked chicken breast, shredded or diced, and 4 cups broccoli florets. Add 1 cup of the 1 1/2 cups shredded cheddar cheese and mix well to coat all ingredients evenly with the creamy sauce.

Transfer the chicken and broccoli mixture into the prepared baking dish. Sprinkle the remaining 1/2 cup shredded cheddar cheese and 1/2 cup grated Parmesan cheese evenly over the top. This golden crown will complete your Creamy Low Carb Chicken Casserole.

Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the cheese topping is melted and golden brown. For the perfect Creamy Low Carb Chicken Casserole, ensure it's heated through.

Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to set slightly, making it easier to portion and enjoy its rich, creamy texture.
