This creamy low carb chicken casserole is the answer to those nights when you need something hearty and comforting but do not want to fuss in the kitchen or load up on carbs. Packed with tender chicken broccoli smoky bacon and a blend of gooey cheeses it is a crowd pleaser that even the pickiest eaters ask for again and again.
I created this dish out of a need to please both the kids and adults at dinner and it quickly landed in my rotation especially on busy weeknights.
Ingredients
- Diced or shredded cooked chicken breast: Use leftover roast or rotisserie for speed and flavor
- Cooked and chopped bacon: Adds smoky richness try using thick cut for extra bite
- Broccoli florets or thawed frozen spinach: Both give bulk and nutrition Broccoli brings crunch while spinach makes it creamy Be sure to drain spinach thoroughly for best texture
- Minced garlic: Brightens the dish It is worth using fresh cloves
- Ranch dressing: Forms the creamy base Pick a good quality one with real herbs for best results
- Shredded mozzarella cheese: Melts beautifully and makes the casserole gooey
- Shredded cheddar cheese: Offers sharpness and bold flavor Choose extra sharp for more kick
- Optional ranch seasoning mix: Kicks up the flavor For quality go with a blend without fillers
Step-by-Step Instructions
- Prepare Vegetables:
- If using fresh broccoli chop into bite-size pieces and boil for one to two minutes until just vibrant green then drain well If using frozen spinach let it thaw fully then squeeze out all water using a clean kitchen towel so your casserole is not watery
- Combine the Main Ingredients:
- In a large mixing bowl place the cooked chicken chopped bacon prepared vegetables minced garlic ranch dressing and half of both cheeses Use a large spoon to really fold it all together so the ranch coats everything evenly If you want extra tang add ranch seasoning to taste Optionally you can mix all this directly in your baking dish to cut down on cleanup
- Transfer to Casserole Dish:
- Lightly grease a nine by thirteen inch baking dish then spread the mixture in an even layer
- Add the Cheese Topping:
- Scatter the remaining mozzarella and cheddar evenly over the surface so every bite gets that bubbling cheese lid
- Bake and Serve:
- Place dish in a 375 degree oven and bake for fifteen minutes or until the cheese on top is melted and golden with some bubbly edges Let it settle two to three minutes before scooping to help the pieces hold their shape

Broccoli remains a favorite in my kitchen not only for its flavor but because it soaks up all that cheesy sauce so well My grandma used to sneak extra vegetables into casseroles and I carry on that tradition now with my own spin
Storage Tips
Let the casserole cool completely then cover tightly and store in the refrigerator for up to four days It also freezes surprisingly well Spoon leftovers into individual containers and freeze for up to three months For reheating use the oven to keep the topping crisp or the microwave for speed
Ingredient Substitutions
You can swap chicken for turkey ham or even cooked ground sausage with great results If you prefer a non dairy option look for coconut based ranch and plant based cheeses If broccoli or spinach is not your favorite cauliflower or kale are good alternatives
Serving Suggestions
This casserole works as a stand alone meal for lunch or dinner I love serving it with a crisp green salad and sliced avocado for a fresh element For gatherings offer it alongside roasted vegetables or even atop mashed cauliflower for double comfort

A Comfort Classic With A Twist
Traditional chicken casseroles often rely on pasta or rice but this version lets you enjoy the same creamy texture without the carbs It is a recipe that bridges the gap between nostalgic flavors and modern eating I love that it brings everyone to the table no matter their diet preferences
