- 2 cups cooked (shredded) chicken: Supplies lean protein to keep the dish filling and satisfying.
- 4 slices bacon: Crispy bacon bits introduce a smoky, salty depth to the casserole.
- 3 cups grated cheddar cheese (divided): Adds creamy richness and a golden cheesy crust when baked.
- 2 large eggs: Bind the casserole together for perfect slice-ability and texture.
- 1 teaspoon salt: Enhances all the natural flavors.

How to Make Low Carb Chicken Casserole Recipe
Step 1: Prep Your Oven and Veggies
Begin by preheating your oven to 350 degrees Fahrenheit. Meanwhile, steam the riced cauliflower and broccoli florets until they’re tender but not mushy—this helps keep the textures distinct and pleasing in the final casserole.
Step 2: Cook and Crumble the Bacon
Fry your bacon slices until they reach that perfect crispiness. Once cooled slightly, crumble them into small, flavorful pieces. The bacon will add that irresistible crunch and smokiness to the dish.
Step 3: Combine Ingredients in a Bowl
In a large mixing bowl, bring together your steamed cauliflower and broccoli, shredded chicken, crumbled bacon, eggs, 2 1/2 cups of grated cheddar cheese, and all the spices: salt, garlic powder, mustard powder, and cracked pepper. Give everything a thorough stir until all ingredients are evenly combined and coated with a cheesy, savory mixture.
Step 4: Assemble the Casserole
Transfer the mixture into a 9×13 inch baking dish, spreading it out in an even layer. Sprinkle the remaining 1/2 cup of cheddar cheese on top—this layer will melt and brown beautifully in the oven, creating a mouthwatering crust.
Step 5: Bake to Perfection
Place your casserole uncovered in the preheated oven and bake for about 30 minutes. The cheese will bubble and turn golden, and the casserole will be heated through and set—ready to serve right away.
How to Serve Low Carb Chicken Casserole Recipe

Garnishes
To elevate the dish even further, consider a sprinkle of fresh chopped parsley or chives for a burst of color and an herbal note that brightens every bite. If you like a little heat, a dash of crushed red pepper flakes makes an exciting addition too.
Side Dishes
Since this casserole packs protein and veggies, light and fresh side dishes work wonderfully. A crisp green salad with a tangy vinaigrette or steamed asparagus spears dressed with lemon are perfect partners that keep the meal balanced and refreshing.
Creative Ways to Present
Serve the casserole straight from the baking dish for a cozy family-style meal or slice it into neat squares to plate individually for a lovely presentation. You can also transform this into a low carb pot pie by topping it with almond flour pastry for an extra special treat.
Make Ahead and Storage
Storing Leftovers
This casserole keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors deepen with time, making leftovers taste just as good—if not better—the next day.
Freezing
You can freeze uncooked Low Carb Chicken Casserole Recipe by assembling it in a freezer-safe dish and covering tightly with foil. Freeze for up to 2 months, then thaw overnight before baking as usual. This makes meal prep a total breeze!
Reheating
Reheat leftovers gently in the oven at 325 degrees Fahrenheit to keep the cheese melty and the texture just right. Alternatively, microwave individual portions, but watch closely to avoid drying out the dish.
FAQs
Can I use other vegetables instead of cauliflower and broccoli?
Absolutely! Zucchini, spinach, or even green beans make great low-carb alternatives that complement the chicken and cheese flavors nicely.
Is it possible to make this recipe dairy-free?
Yes! Swap out cheddar cheese for a dairy-free cheese substitute and use coconut or almond-based milk replacers if needed. The casserole will still be delicious and creamy.
Can I use raw chicken instead of cooked chicken?
Using cooked, shredded chicken is best for this recipe to ensure even cooking and the right casserole texture. If starting with raw chicken, cook it thoroughly before mixing it in.
How spicy is this casserole?
It’s mild and comforting with just a subtle hint of spice from the cracked pepper and mustard powder. You can always add more seasoning to suit your personal taste.
Can I make this recipe vegetarian?
To make it vegetarian, omit the bacon and chicken and add extra vegetables or a plant-based protein like tofu or tempeh for added texture and flavor.
