Ingredients You’ll Need

The beauty of this Easy Low Carb Chicken Casserole lies in how uncomplicated yet complementary the ingredients are. Each element contributes essential flavors and textures—creating layers of savory delight without fuss.

• 4 cups diced or shredded cooked chicken breast: The protein-packed base that keeps this casserole hearty and filling.
• 8 slices cooked and chopped bacon: Adds smoky crunch and irresistible flavor that elevates every bite.
• 5 cups broccoli florets OR 1 pound thawed frozen spinach (well-drained): Fresh green veggies bring color, nutrients, and a light, satisfying texture.
• 3 cloves minced garlic: Introduces a subtle punch of aromatic savory goodness.
• 1 cup ranch dressing: Creamy, tangy binder that melds all ingredients into one cohesive dish.
• 1/2 cup shredded mozzarella cheese (plus extra for topping): Melts beautifully for gooey cheesiness throughout.
• 1/2 cup shredded cheddar cheese (plus extra for topping): Adds sharpness and a golden 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). If you’re working with frozen spinach, make sure it’s completely thawed and squeeze out excess water to avoid a watery casserole. For those using fresh broccoli, blanch the florets in boiling water for 1 to 2 minutes until they turn bright green, then drain well to keep them crisp-tender. This step ensures that your veggies retain their freshness and vibrant texture inside the casserole.

Step 2: Combine the Main Ingredients

In a large bowl (or directly in your casserole dish if you want fewer dishes), mix together the diced or shredded chicken breast, chopped bacon, prepared broccoli or spinach, and minced garlic. Pour in the ranch dressing and sprinkle in the mozzarella and cheddar cheeses, saving half of the cheese for the topping. For an extra flavor kick, feel free to fold in 1 to 3 teaspoons of ranch seasoning mix. Stir everything gently until all ingredients are evenly combined and ready for baking.

Step 3: Transfer to Casserole Dish

Once mixed, spoon your delicious chicken and vegetable mixture into a 9×13 inch (23×33 cm) casserole dish. Spread it out evenly to ensure every bite will have a perfect balance of all the tasty ingredients.

Step 4: Add the Cheese Topping

Sprinkle the remaining 1/2 cup of shredded mozzarella and 1/2 cup cheddar cheese evenly over the top of your casserole. This step creates a beautifully golden, bubbling cheese crust that adds irresistibly gooey texture and rich flavor.

Step 5: Bake and Serve

Place your casserole in the preheated oven and bake for about 15 minutes until the topping is hot, melted, and bubbly with occasional golden spots. When out of the oven, let it rest for a few minutes to settle, then scoop out generous servings and enjoy the comforting warmth of this easy low carb chicken casserole.

How to Serve Easy Low Carb Chicken Casserole

Garnishes

Adding a fresh garnish can brighten up the dish and add an extra layer of flavor. Sprinkle chopped fresh parsley, chives, or green onions on top just before serving. A light drizzle of hot sauce or a squeeze of lemon juice also works wonders if you enjoy a little zing.

Side Dishes

This casserole is wonderfully filling on its own but pairs beautifully with crisp, refreshing sides. Consider serving it alongside a simple mixed green salad, cauliflower rice, or roasted asparagus for an extra low carb boost that complements the richness of the casserole.

Creative Ways to Present

For an inviting presentation, serve portions in individual ramekins or bake the casserole in smaller dishes for single servings. You can also accompany it with homemade keto-friendly garlic breadsticks or use colorful vegetables as edible “dippers” for a fun sharing experience.

Make Ahead and Storage

Storing Leftovers

Leftover Easy Low Carb Chicken Casserole stores wonderfully in an airtight container in the refrigerator for up to 3–4 days. The flavors actually meld even more as it sits, making for great next-day lunches or dinners.

Freezing

This casserole freezes well, making it an excellent option for meal prepping. Freeze in portions or as a whole in a freezer-safe container for up to 2 months. Be sure to let it cool completely before freezing to maintain the best texture and flavor.

Reheating

To reheat, place a portion in the oven at 350°F (175°C) for around 15 minutes until warmed through and the cheese topping becomes bubbly again. You can also microwave single servings, though reheating in the oven helps retain that lovely crispy cheesy crust.

FAQs

Can I use frozen broccoli instead of fresh?

Yes, you can use frozen broccoli as a substitute. Just be sure to thaw and drain it thoroughly to avoid excess moisture in your casserole, which can make it soggy.

Is this casserole suitable for keto diets?

Absolutely. With its focus on protein, healthy fats, and low carb vegetables, this recipe fits well within keto guidelines while delivering satisfying flavors.

Definitely. Vegetables like bell peppers, mushrooms, or cauliflower can be added, but keep in mind they may affect the cooking time and overall moisture content. Adjust accordingly for best results.

How can I make this dish dairy-free?

To make this dairy-free, replace the cheeses with dairy-free alternatives and use a ranch dressing free of dairy products, or substitute with a creamy avocado or cashew-based sauce.
