Ingredients

  • 4 slices bacon
  • 3 cups grated cheddar, divided
  • 2 large eggs
  • 1 teaspoon salt
  • 1 teaspoon garlic powder
  • 1/2 teaspoon mustard powder
  • 1/2 teaspoon cracked pepper

Notes & Substitutions

Equipment

You won’t need many specialized tools for this simple recipe.

  • Large mixing bowl
  • 9×13-inch baking dish
  • Large skillet (for bacon)
  • Steamer basket or microwave-safe dish
  • Measuring cups and spoons

Instructions

Follow these simple steps to create your delightful Easy Low Carb Chicken Casserole:

Step 1: Prep the Veggies

Preheat your oven to 350°F (175°C). Steam the cauliflower rice until it’s tender-crisp. You can use a steamer basket on the stovetop or a microwave-safe bowl. Next, steam the broccoli florets until they are tender. Ensure both the cauliflower and broccoli are thoroughly drained to prevent a watery casserole. Excess moisture is your enemy here!

Step 2: Cook the Bacon

Fry the bacon in a large skillet over medium heat until it’s wonderfully crispy. Once cooked, remove the bacon from the skillet and place it on a paper towel-lined plate to drain any excess grease. Once cooled slightly, crumble the crispy bacon into small, savory pieces. This adds a fantastic textural and flavor component to your low-carb chicken bake.

Step 3: Combine Ingredients

In a large mixing bowl, combine the cooked shredded chicken. Add the thoroughly drained steamed cauliflower rice, steamed broccoli, and the crumbled bacon. Stir in 2 1/2 cups of the grated cheddar cheese. Next, add the two large eggs and all of your spices: salt, garlic powder, mustard powder, and cracked pepper. Mix everything thoroughly until all the ingredients are well combined and evenly distributed. This ensures every bite of your chicken casserole is packed with flavor.

Step 4: Bake the Casserole

Evenly spread the combined mixture into your prepared 9×13-inch baking dish. Sprinkle the top with the remaining 1/2 cup of grated cheddar cheese. Bake the casserole uncovered for 30 minutes, or until the cheese on top is bubbly and golden brown. Once baked, let the casserole rest for a few minutes before serving. This allows it to set up nicely and makes for easier serving.

Pro Tips & Troubleshooting

  • Prevent a Watery Casserole: Always thoroughly drain all steamed vegetables, especially the cauliflower rice. Pat riced cauliflower dry with paper towels for best results.
  • Achieve Crispy Bacon: Cook bacon to your desired crispness. Drain excess fat properly by patting it with paper towels after frying.
  • Ensure Proper Binding: Do not omit the eggs; they are crucial for holding the casserole together. Ensure all ingredients are well combined before baking.
  • Flavor Boosts: For extra richness, add a touch of cream cheese to the mixture. Experiment with different cheese blends like Monterey Jack or colby for varied flavor. Adjust seasonings to taste before baking.

Serving, Storage, & Variations

This Easy Low Carb Chicken Casserole is wonderfully versatile for all your meal planning needs.

  • Serving Suggestions: Serve this hearty casserole as a complete standalone meal. For a fresh contrast, pair it with a simple side salad tossed in a light vinaigrette.
  • Storage Instructions: Store any leftover portions in an airtight container. Refrigerate for up to 3-4 days. Reheat gently in the microwave or oven until warmed through.
  • Freezing Guidelines: This low-carb chicken casserole freezes beautifully. Divide it into individual portions for quick, convenient meals later. Thaw overnight in the refrigerator before reheating.
  • Recipe Variations: Get creative! Add other cooked meats like ground turkey or cooked sausage. Mix in different low-carb vegetables such as spinach, bell peppers, or mushrooms. Experiment with various cheese combinations for unique flavors. For a creamier texture, stir in a low-carb creamy sauce base like Alfredo before baking.
