Easy Low Carb Chicken Casserole Recipe
Introduction
This easy low carb chicken casserole is a comforting, cheesy dish packed with broccoli, bacon, and tender chicken. It’s perfect for a quick weeknight dinner or meal prep when you want something satisfying without the carbs.

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 (such as Hidden Valley Original Ranch)
- For the topping:
- 1/2 cup shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
Instructions
- Step 1: Preheat your oven to 375°F (191°C). Prepare the vegetables by boiling the broccoli florets for 1–2 minutes until bright green, then drain well. If you prefer, you can use 1 pound of thawed frozen spinach instead—just thaw it completely and squeeze out any excess water.
- Step 2: In a large bowl, combine the cooked chicken, chopped bacon, prepared vegetables, minced garlic, ranch dressing, and the 1/2 cup each of shredded mozzarella and cheddar cheese. Mix everything thoroughly. You can also mix all ingredients directly in a 9×13 inch (23×33 cm) casserole dish to save on cleanup.
- Step 3: Transfer the mixture to the casserole dish if you haven’t mixed it there already. Spread it out evenly.
- Step 4: Sprinkle the remaining 1/2 cup shredded mozzarella and 1/2 cup shredded cheddar cheese evenly over the top of the casserole.
- Step 5: Bake in the preheated oven for about 15 minutes, or until the cheese topping is melted, hot, and bubbly. Let the casserole cool slightly before serving.
Tips & Variations
- For extra flavor, add a pinch of ranch seasoning mix to the filling. You can also swap out the broccoli for well-drained frozen spinach.
- Use rotisserie chicken to save time on cooking the chicken from scratch.
- Try adding a handful of chopped green onions or a sprinkle of crushed red pepper flakes for a subtle kick.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the casserole in the oven at 350°F (175°C) for about 10-15 minutes until heated through, or microwave individual portions until hot.
