Directions: Low Carb Chicken Casserole

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step is crucial for achieving that perfect bubbly, golden top.
Step 2: Prepare the Chicken and Broccoli
In a large mixing bowl, combine your cooked and shredded chicken with the cooked broccoli florets. Season with salt and pepper to taste.
Step 3: Mix in the Cheesy Goodness
Add in 2 cups of the shredded cheese, the light sour cream, garlic powder, dried parsley, and Italian seasoning. Stir everything together until well combined. This mix should be creamy and packed with flavor.
Step 4: Transfer to Baking Dish
Spread the mixture evenly into a greased 9×13 inch baking dish. This ensures even cooking and makes for easy serving.
Step 5: Top with Remaining Cheese
Sprinkle the remaining 1 cup of shredded cheese on top of the casserole. This will create a delicious, cheesy crust as it bakes.
Step 6: Bake to Perfection
Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
Step 7: Let it Rest
Once out of the oven, let the casserole rest for about 5-10 minutes before serving. This allows the flavors to meld together and makes it easier to scoop out portions.
Substitutions by Category

- Protein: Use cooked turkey or rotisserie chicken for a different flavor.
- Vegetables: Swap broccoli for cauliflower, spinach, or mixed vegetables.

Don’t Do This
- Don’t skip seasoning! Proper seasoning elevates the flavor of your Low Carb Chicken Casserole.
- Avoid overcooking the chicken beforehand; it should be moist for the best texture.
- Don’t use frozen broccoli without thawing it first, as it can release excess moisture during baking.
