Step-By-Step Cooking Instructions of this Low-Carb Chicken Casserole

 1: Preheat the Oven

Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch casserole dish with a bit of butter or olive oil to prevent sticking.

2: Prepare the Vegetables

• If using broccoli, steam or blanch it for 1-2 minutes until slightly tender. Drain and set aside.
• If using frozen spinach, thaw completely and squeeze out any excess moisture.

 3: Cook the Turkey Bacon

• In a skillet over medium heat, cook the turkey bacon until crispy, about 5-7 minutes.
• Let it cool slightly, then chop into small pieces.

 4: Mix the Ingredients

In a large mixing bowl, combine:

• Shredded chicken
• Cooked turkey bacon
• Broccoli and spinach
• Minced garlic
• Heavy cream
• Sour cream
• Salt, black pepper, smoked paprika, garlic powder, and onion powder

Stir everything together until well coated.

5: Assemble the Casserole

• Transfer the mixture to your prepared casserole dish.
• Sprinkle the shredded mozzarella and cheddar cheese evenly over the top.

6: Bake the Casserole

• Place the dish in the preheated oven and bake for 20-25 minutes, until the cheese is melted and bubbly.
• If you like a crispy, golden top, broil for an additional 2-3 minutes at the end.

 7: Let It Rest & Serve

Remove from the oven and let the casserole sit for 5 minutes before serving. This helps the flavors meld together and makes it easier to cut.

How to Serve this Low-Carb Chicken Casserole

This casserole is incredibly versatile. Here are some delicious ways to serve it:

• Over Cauliflower Rice – Keeps it low-carb while adding texture.
• With a Side Salad – A crisp Greek salad with cucumbers, tomatoes, and feta complements the richness.
• With Roasted Vegetables – Try roasted zucchini, asparagus, or bell peppers.
• Wrapped in Lettuce Leaves – A fresh and fun way to enjoy leftovers.

Pairing Suggestions

This dish pairs well with:

• A refreshing cucumber and tomato salad with olive oil dressing
• Roasted Brussels sprouts or green beans for an extra veggie boost
• A warm bowl of soup, like creamy mushroom or tomato basil

Storage, Freezing & Reheating Instructions

Storing Leftovers:

• Keep leftovers in an airtight container in the fridge for up to 4 days.

Freezing Instructions:

• Place cooled portions in freezer-safe containers and store for up to 3 months.

Reheating Instructions:

• Oven: Reheat at 350°F for 10-15 minutes until warmed through.
• Microwave: Heat in 30-second intervals, stirring in between to prevent uneven heating.

Common Mistakes to Avoid

1. Not Draining the Spinach – Excess moisture makes the casserole watery.
2. Overcooking the Chicken – Dry chicken ruins the texture, so use pre-cooked or rotisserie chicken.
3. Skipping the Cheese Topping – The golden, melty cheese layer adds incredible flavor.
4. Using Too Much Salt – Since cheese and turkey bacon are salty, taste before adding extra salt.

Pro Tips

• Use rotisserie chicken for extra flavor and convenience.
• Shred your own cheese instead of using pre-packaged shredded cheese for better meltability.
• Broil for 2-3 minutes at the end for a crispy, golden cheese crust.

Creative Ways to Customize This Casserole

One of the best things about this low-carb chicken casserole is how versatile it is. With a few simple tweaks, you can completely transform the dish to match your taste preferences or dietary needs. Here are a few creative ideas:

• Make it Spicy: Add a dash of cayenne pepper, jalapeños, or red pepper flakes for some heat. A drizzle of hot sauce before serving also adds a kick.
• Try Different Cheeses: While mozzarella and cheddar create the perfect melt, you can experiment with pepper jack, gouda, or parmesan for a new flavor profile.
• Go Mediterranean: Add black olives, sun-dried tomatoes, and feta cheese to give the casserole a Mediterranean twist.
• Make It Extra Creamy: Stir in a little cream cheese or Greek yogurt to the mixture for a richer texture.
• Add More Veggies: If you love vegetables, mix in bell peppers, mushrooms, zucchini, or cauliflower to boost the nutritional content.
• Use a Different Protein: Swap out the chicken for ground turkey, shredded beef, or even shrimp for a fresh take on the dish.

This casserole is a blank canvas—you can get creative with seasonings, proteins, and vegetables to make it perfect for your family’s preferences.

Best Side Dishes to Serve with This Casserole

While this low-carb chicken casserole is hearty enough on its own, pairing it with the right sides can make the meal even better. Here are some tasty, low-carb-friendly options:

How to Make This Casserole Dairy-Free

If you’re avoiding dairy but still want to enjoy this low-carb chicken casserole, don’t worry—there are easy substitutions that keep the dish creamy and flavorful:
