Ingredients You’ll Need
Let’s dive into the short but powerful list of ingredients you’ll need. Each one plays an important role, adding not just nutrition but heartiness, color, and crowd-pleasing flavor to your Easy Low Carb Chicken Casserole.
- Cooked Chicken Breast (4 cups diced or shredded): The star of the show, bringing lean, satisfying protein to every bite.
- Bacon (8 slices, cooked and chopped): For irresistible smokiness and a delightful crunch that ties the casserole together.
- Broccoli Florets (5 cups) or Frozen Spinach (1 pound, well-drained): Choose your favorite to add a pop of color and a healthy dose of greens.
- Minced Garlic (3 cloves): For that savory, aromatic boost that rounds out the entire casserole.
- Ranch Dressing (1 cup): It’s the creamy, tangy base that infuses everything with bold flavor—plus, it keeps things super easy!
- Shredded Mozzarella Cheese (1 cup total, divided): Melts into irresistible gooeyness, inside and on top.
- Shredded Cheddar Cheese (1 cup total, divided): Adds sharp, classic cheddar notes both mixed in and as a golden topping.
- Optional Ranch Seasoning Mix (1–3 teaspoons): Kick up the ranch flavor even more—especially good if you want extra zing.
How to Make Easy Low Carb Chicken Casserole
Step 1: Prepare the Vegetables
Start by getting your veggies ready. If you’re using fresh broccoli, give it a quick boil for just a minute or two until it turns a bright green, then drain promptly to keep it crisp-tender. For frozen spinach lovers, thaw and squeeze firmly to get rid of any excess water. This simple prep ensures your Easy Low Carb Chicken Casserole has perfect texture—never soggy!
Step 2: Combine the Main Ingredients
Grab a big mixing bowl (or save on cleanup and use the casserole dish itself). Add your diced or shredded chicken, chopped bacon, prepared veggies, minced garlic, ranch dressing, half of the mozzarella, and half of the cheddar. If you want even bigger ranch flavor, toss in 1 to 3 teaspoons of ranch seasoning mix. Stir everything together so all that flavor is blended and every bite is a winner.
Step 3: Transfer to Casserole Dish
Spoon the well-mixed filling into a 9×13 inch casserole dish, spreading it out evenly. This helps the casserole bake consistently and ensures every serving is balanced with meat, veg, and cheesy bits.
Step 4: Add the Cheese Topping
Top your casserole with the remaining shredded mozzarella and cheddar. This layer turns golden and bubbly in the oven, inviting everyone to the table with that irresistible, melty-cheese look and aroma.
Step 5: Bake and Serve
Bake in a preheated 375°F (191°C) oven for about 15 minutes—just long enough for the cheesy top to get beautifully melted and bubbling. Let it rest a few minutes before serving, so you get those perfect creamy-yet-sliceable portions.
How to Serve Easy Low Carb Chicken Casserole

Garnishes
For a fresh flourish, shower the casserole with chopped parsley, sliced green onions, or even extra crispy bacon bits right before serving. Not only does this add a pop of color, but it gives every plate a lovely finishing touch that looks as good as it tastes.
Side Dishes
This Easy Low Carb Chicken Casserole pairs beautifully with light, crisp sides like a tangy green salad, roasted asparagus, or zucchini noodles. These sides keep things low carb while giving you a satisfying variety at dinnertime.
Creative Ways to Present
Feeling playful? Spoon the casserole into individual ramekins for a dinner party, or serve it over cauliflower rice for a heartier meal. You can also tuck scoops into low-carb wraps or lettuce leaves for fun, portable leftovers.
Make Ahead and Storage
Storing Leftovers
Leftover casserole will keep happily in the fridge for 3–4 days. Just cover the dish tightly with foil or transfer portions to airtight containers, and you’ll have a grab-and-go lunch or effortless dinner at your fingertips.
Freezing
To freeze, let the Easy Low Carb Chicken Casserole cool completely. Wrap the whole dish (or individual portions) well with plastic wrap and aluminum foil, then freeze for up to 2 months. Thaw overnight in the fridge before reheating for best texture.
Reheating
To reheat, pop your casserole (covered) into a 350°F oven until warmed through and the cheese is melty again, about 15–20 minutes. A microwave works for single servings, just use a lower power setting to keep things creamy.
