Last weekend, I decided to host a casual family lunch after a long week of errands and work. My grandchildren were running around the house, my daughter was unpacking groceries, and my husband was trying to sneak a few quiet moments with his newspaper. I wanted something hearty and comforting that could please everyone without keeping me tied to the stove.
That’s when I remembered a casserole recipe I had tweaked over the years—a low-carb chicken casserole that’s rich, cheesy, and packed with vegetables. As I started prepping, the aroma of sizzling garlic and bacon filled the kitchen, instantly lifting the mood.
My granddaughter peeked into the oven, asking when she could taste the cheesy goodness, and my husband joked about “double-checking the cheese-to-chicken ratio.” Mixing the ingredients, I felt that familiar warmth that comes from cooking meals that bring everyone together.
By the time it baked, the top was bubbly, golden, and inviting—just what I needed for a stress-free family lunch. Each bite was creamy, flavorful, and satisfying, proving that comfort food can still be low-carb.
This casserole has become a go-to in my household. It’s practical, simple, and doesn’t require fancy ingredients—but it makes everyone smile, which is exactly why I keep making it.
Short Description
A creamy, cheesy low-carb chicken casserole packed with broccoli (or spinach), bacon, and garlic, topped with a golden layer of mozzarella and cheddar cheese. Perfect for a quick family meal or a cozy weekend lunch.
Key Ingredients
For the casserole:
- 4 cups diced or shredded cooked chicken breast
- 8 slices cooked and chopped bacon
- 5 cups broccoli florets OR 1 pound thawed frozen spinach (well-drained)
- 3 cloves garlic, minced
- 1 cup ranch dressing
- ½ cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
For the topping:
- ½ cup shredded mozzarella cheese
- ½ cup shredded cheddar cheese
Optional:
-
1–3 teaspoons ranch seasoning mix for added flavor
Tools Needed
- Large mixing bowl
- 9×13-inch casserole dish
- Knife and cutting board
- Garlic press (optional)
- Cheese grater
- Spoon or spatula
Cooking Instructions
Step 1: Prepare Vegetables
Preheat your oven to 375°F (191°C) to get it ready for baking. Prepare your vegetables depending on what you’re using.
For frozen spinach, make sure it’s fully thawed and squeeze out all excess water so the casserole doesn’t become watery. For fresh broccoli, give it a quick boil for 1–2 minutes until it turns a bright green, then drain thoroughly.
Step 2: Combine Main Ingredients
In a large bowl, mix together the diced or shredded chicken, chopped cooked bacon, prepared vegetables, minced garlic, ranch dressing, and both the mozzarella and cheddar cheeses.
You can add 1–3 teaspoons of ranch seasoning if you want extra flavor. To save time and reduce dishes, you can also mix everything directly in your casserole dish.
Step 3: Transfer to Casserole Dish
Pour the combined mixture into a 9×13-inch (23×33 cm) casserole dish, spreading it evenly so it bakes uniformly.
Step 4: Add Cheese Topping
Sprinkle the remaining ½ cup mozzarella and ½ cup cheddar cheese evenly over the top to create a golden, bubbly layer when baked.
Step 5: Bake and Serve
Bake for about 15 minutes, or until the cheese topping is melted and the casserole is heated through. If the top starts browning too fast, cover loosely with foil and continue baking. Remove from the oven, let it cool slightly, and serve warm for a comforting, cheesy meal.
