Easy Low Carb Chicken Casserole Recipe
Introduction
This easy low carb chicken casserole is a creamy, comforting dish perfect for busy weeknights. Packed with broccoli, bacon, and cheese, it’s simple to make and sure to satisfy your cravings while keeping carbs in check.

Ingredients
- 5 cups broccoli florets
- 8 slices cooked bacon, chopped into 1/2-inch pieces
- 4 cups cooked chicken, shredded or diced into 1/2-inch pieces
- 3 cloves garlic, finely minced
- 1/2 cup shredded mozzarella cheese
- 1/2 cup shredded cheddar cheese
- 1 cup ranch dressing (Hidden Valley Original Ranch recommended)
- 1/2 cup shredded cheddar cheese (for topping)
- 1/2 cup shredded mozzarella cheese (for topping)
Instructions
- Step 1: Preheat your oven to 375°F (191°C). If using fresh broccoli, boil the florets for 1–2 minutes until bright green, then drain well. (If using frozen spinach, thaw completely and squeeze out excess water.)
- Step 2: In a large bowl, combine the cooked chicken, chopped bacon, prepared broccoli, finely minced garlic, ranch dressing, and the 1/2 cup each of shredded mozzarella and cheddar cheese. Mix everything thoroughly. You can also mix directly in the casserole dish if you prefer fewer dishes.
- Step 3: Transfer the mixture into a 9×13 inch (23×33 cm) casserole dish, spreading it evenly.
- Step 4: Sprinkle the remaining 1/2 cup each of shredded cheddar and mozzarella cheeses evenly over the top of the casserole.
- Step 5: Bake in the preheated oven for about 15 minutes, or until the top is hot, bubbly, and lightly golden. Remove from oven, let cool slightly, then serve warm.

- Feel free to add ranch seasoning mix for more intense flavor if desired.
- Using pre-cooked chicken and bacon saves time for a quick weeknight meal.
- The casserole can be reheated gently in the oven or microwave for leftovers.
- For a crispier top, broil the casserole for the last 1-2 minutes, watching carefully to prevent burning.
