• 1/2 cup shredded mozzarella cheese: Melts beautifully, giving smooth texture and mild flavor.
• 1/2 cup shredded cheddar cheese: Adds sharpness and a rich, golden finish.
• 1/2 cup shredded mozzarella cheese (for topping): Ensures a delectably cheesy crust on top.

How to Make Easy Low Carb Chicken Casserole

Step 1: Prepare Vegetables

Start by preheating your oven to 375°F (191°C) to get everything ready for baking. If you’re using spinach, be sure it’s fully thawed and squeeze as much water out as possible to keep the casserole from becoming soggy. For broccoli lovers, boil the florets briefly—just 1 to 2 minutes until they turn a bright green—and then drain them well to preserve that lovely crunch and vibrant color.

Step 2: Combine the Main Ingredients

In a large bowl, toss together the diced or shredded chicken, chopped bacon, your prepared vegetables, and the minced garlic. Add in the cup of ranch dressing along with half a cup each of shredded mozzarella and cheddar cheese. If you like, sprinkle in 1 to 3 teaspoons of ranch seasoning mix to amplify that herby goodness. Mixing everything thoroughly ensures that each bite bursts with balanced flavor and a creamy texture. To save time and dishes, you can even stir everything directly in your casserole dish if you prefer.

Step 3: Transfer to Casserole Dish

Next, spread the combined mixture evenly into a 9×13 inch casserole dish. This gives it enough space to cook uniformly, letting the flavors meld beautifully while giving you that classic casserole look.

Step 4: Add the Cheese Topping

Sprinkle the remaining half cup of mozzarella and cheddar cheeses evenly over the top of the casserole. This step is what turns the dish into a cheesy masterpiece with a golden, bubbly crust that’s simply irresistible.

Step 5: Bake and Serve

Pop your casserole into the oven and bake for about 15 minutes, or until the cheese topping is hot and bubbling nicely. Once it’s out of the oven, give it a few minutes to cool slightly—it helps everything set perfectly. Then, slice it up and enjoy the creamy, savory goodness of your Easy Low Carb Chicken Casserole right away.

How to Serve Easy Low Carb Chicken Casserole

Garnishes

Adding a sprinkle of freshly chopped parsley or green onions on top brightens the dish with a pop of color and a subtle fresh flavor. A little cracked black pepper or a dusting of paprika can also enhance both visual appeal and taste.

Side Dishes

To complement the richness of the casserole, serve it alongside a crisp green salad dressed with lemon vinaigrette or some roasted veggies to keep dinner light and well-rounded. Cauliflower rice or a simple cucumber and tomato salad also pairs beautifully, maintaining the low-carb spirit of the meal.

Creative Ways to Present

If you want to impress guests or meal prep with style, try serving the casserole in individual ramekins or small cast-iron skillets. Layering with extra veggies or even adding a dollop of sour cream or avocado on top can add fun textures and flavors that keep this classic dinner exciting.
