Step‑by‑Step Instructions for Low Carb Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (191°C). This ensures a perfectly cooked Low Carb Chicken Casserole when you’re ready to bake. A well-prepared oven will help create that deliciously bubbly and golden top you’ll want for this hearty dish.
Step 2: Prepare the Broccoli
If using fresh broccoli, bring a pot of water to a boil and add the florets for just 1–2 minutes until they’re bright green. Drain and set aside to cool. Alternatively, if using frozen broccoli, make sure to thaw it completely and squeeze out any excess water to prevent a soggy casserole.
Step 3: Combine Ingredients
In a large mixing bowl, combine the cooked chicken, crispy bacon, broccoli, minced garlic, ranch dressing, and both shredded mozzarella and cheddar cheeses. Stir the ingredients together until everything is evenly coated. This step ensures every bite of your Low Carb Chicken Casserole is bursting with flavor and richness.
Step 4: Transfer to Casserole Dish
Spray a 9×13 inch casserole dish with non-stick cooking spray for easy cleanup, then transfer the mixture into the dish. Spread it out evenly to ensure even cooking throughout the casserole. At this point, you can opt to mix the ingredients directly in the casserole dish to save on bowl washing.
Step 5: Add Topping
Once the main ingredients are spread evenly in the casserole dish, sprinkle additional mozzarella and cheddar cheese generously over the top. This will create a wonderfully melty and golden crust as it bakes, enhancing the deliciousness of your Low Carb Chicken Casserole.
Step 6: Bake the Casserole
Place the casserole in your preheated oven and bake for about 15 minutes. You’ll know it’s done when the cheese is hot, bubbly, and slightly golden on top. This delightful visual cue means your Low Carb Chicken Casserole is ready to be enjoyed!
Step 7: Cool and Serve
After baking, carefully remove the casserole from the oven and let it cool for a few minutes. This helps the flavors meld beautifully and makes serving easier. Once slightly cooled, scoop out portions of your hearty Low Carb Chicken Casserole, and get ready to savor a fulfilling meal with your loved ones!

Easy Low Carb Chicken Casserole Recipe FAQs
What type of broccoli should I use for the casserole?
Absolutely, you can use either fresh or frozen broccoli! If using fresh, boil the florets for just 1–2 minutes until they’re bright green before draining. For frozen, make sure to thaw completely and squeeze out any excess water to avoid a soggy casserole.
How long can I store leftovers in the fridge?
Leftovers from your Easy Low Carb Chicken Casserole can be stored in an airtight container in the fridge for up to 3 days. When reheating, I recommend using the oven at 350°F (175°C) to maintain that delicious texture, which usually takes about 20 minutes.

If you find your casserole is a bit dry, it might be due to using lean chicken without enough moisture. For future batches, I recommend using shredded rotisserie chicken for added juiciness or adding a touch more ranch dressing to keep it creamy.
Is this casserole suitable for dietary restrictions?
Absolutely! This Easy Low Carb Chicken Casserole is keto-friendly, making it a great choice for those on a low-carb diet. However, if you have any specific allergies, be sure to check the labels for ranch dressing and cheese, as some brands may contain allergens like dairy or preservatives.
