Step‑by‑Step Instructions for Low Carb Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is perfect for our Low Carb Chicken Casserole to bake thoroughly, ensuring the cheese melts beautifully. While the oven warms up, gather your mixing bowls and cooking utensils, preparing for a delightful cooking experience that will fill your kitchen with mouthwatering aromas.
Step 2: Prepare the Chicken and Veggies
In a large mixing bowl, combine 2 cups of shredded cooked chicken, 1 cup of broccoli florets, 1 cup of diced bell peppers, and 1 cup of cauliflower rice. Use a spatula to gently fold the ingredients together until they are evenly mixed, creating a colorful and nutritious base for your casserole. Set this mixture aside as we craft the creamy sauce.
Step 3: Make the Creamy Sauce
In another bowl, whisk together 1 cup of heavy cream, 2 teaspoons of garlic powder, 1 teaspoon of onion powder, ½ teaspoon of paprika, ½ teaspoon of black pepper, and salt to taste. Continue whisking until the mixture is smooth and fragrant, with a creamy texture that will envelop the chicken and vegetables. This step is vital for infusing our Low Carb Chicken Casserole with rich flavors.
Step 4: Combine and Mix
Pour the creamy mixture over the chicken and vegetable blend in the first bowl. Mix everything thoroughly until all ingredients are well coated with the creamy sauce, ensuring each bite of the casserole is packed with flavor and nutrition. The combination of the chicken and veggies with the sauce will create a tempting mixture that’s ready for the oven.
Step 5: Transfer to Baking Dish
Grease a baking dish and carefully transfer the combined mixture into it. Spread it out evenly to ensure even cooking. This is the moment to create a hearty and comforting base for your Low Carb Chicken Casserole, so take your time to make it as even as possible.
Step 6: Add the Cheese Topping
Sprinkle 1 cup of shredded cheese—either cheddar or mozzarella—generously over the top of the casserole. Make sure the cheese covers the entire surface to create that delicious, golden-brown crust while baking. This layered topping will melt in the oven and add a delightful finish to your dish.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on the casserole as it bakes; it’s ready when the cheese is golden brown and bubbly, filling the kitchen with its savory scent. This baking time allows the flavors to meld beautifully together, creating a scrumptious Low Carb Chicken Casserole.
Step 8: Cool Before Serving
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. This brief resting period allows the dish to set slightly, making it easier to serve. Enjoy the comforting flavors that have come together in this delightful casserole!

Make Ahead Options
These Low Carb Chicken Casserole preparations are perfect for meal prep enthusiasts! You can combine the shredded chicken, broccoli, bell peppers, and cauliflower rice up to 24 hours in advance, storing the mixture in an airtight container in the refrigerator. To maintain quality, prepare the creamy sauce and pour it over the chicken and veggies just before baking, which ensures that the vegetables stay crisp and the flavors fresh. When you’re ready to serve, simply transfer the mixture into a greased baking dish, sprinkle with cheese, and bake for 35-40 minutes in a preheated oven. This makes getting a delicious, wholesome meal on the table a breeze, even on your busiest days!
