Low Carb Chicken Casserole Ingredients
For the Casserole
• Chicken – 4 cups diced or shredded cooked chicken breast; a great main protein source, rotisserie chicken can speed up your prep time.

• Broccoli florets – 5 cups or 1 pound thawed frozen spinach, well-drained; packed with nutrients, cauliflower can be swapped in for variety.
• Garlic – 3 cloves minced; enhances flavor and aroma; garlic powder works in a pinch if you’re short on time.
• Ranch dressing – 1 cup; adds moisture and flavor that ties the casserole together; a homemade mixture of mayo and sour cream can be just as tasty.

• Shredded cheddar cheese – 1 cup total, divided; adds sharpness and depth to flavors; feel free to use Colby cheese as a substitute.
For the Topping
• Additional mozzarella cheese – Use the remaining mozzarella for a bubbly and golden topping; adding it towards the end of baking gives the perfect melty finish.

Step‑by‑Step Instructions for Low Carb Chicken Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (191°C). This essential step ensures your Easy Low Carb Chicken Casserole bakes evenly and achieves that golden, bubbly top you’re aiming for. Set your oven timer while you prep the ingredients; this will save you time and keep everything moving smoothly.
Step 2: Prepare the Vegetables
If you’re using frozen spinach, be sure to thaw it and squeeze out as much excess liquid as possible for the best texture. For fresh broccoli, par-boil the florets in salted water for about 2-3 minutes until they are just tender but still bright green. Draining the vegetables thoroughly is key to a deliciously creamy casserole.
Step 3: Combine the Ingredients
In a large mixing bowl, combine the diced or shredded cooked chicken, chopped cooked bacon, drained veggies, and minced garlic. Pour in the ranch dressing, mixing everything until well combined. Add half of the shredded mozzarella and cheddar cheese, blending these cheesy layers into your Easy Low Carb Chicken Casserole for creamy perfection.
Step 4: Transfer the Mixture
Carefully pour the chicken and vegetable mixture into a greased 9×13 inch casserole dish. Use a spatula to spread it evenly throughout the dish, ensuring an even cooking process. This step is crucial for achieving the wonderfully creamy texture that makes your casserole so delightful.
Step 5: Add Toppings
Once your mixture is evenly spread, sprinkle the remaining mozzarella and cheddar cheese evenly over the top. This extra layer of cheese creates a deliciously gooey topping that will bubble and brown beautifully in the oven, making your Easy Low Carb Chicken Casserole irresistible.
Step 6: Bake the Casserole
Place your casserole in the preheated oven and bake for about 15-20 minutes. Keep an eye on it until the top is hot and bubbly, signaling that it’s perfectly cooked through. You want that melted cheese to be golden and slightly crisped for the best flavor experience.
Step 7: Serve and Enjoy
Once baked, allow the casserole to cool for a few minutes before serving. This resting time helps everything set a bit, making it easier to serve. Dive into your home-cooked Easy Low Carb Chicken Casserole, savor the comforting flavors, and enjoy the smiles it brings to your dinner table!

Low Carb Chicken Casserole Recipe FAQs
What is the best way to select chicken for this casserole?
When selecting chicken, opt for fresh, high-quality chicken breasts that are pink and plump, without any dark spots. If you’re short on time, a rotisserie chicken is a fantastic option for ease of prep. Just shred the chicken and it will blend seamlessly with the other ingredients.
How long will leftovers stay fresh in the fridge?
Absolutely! Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. It’s essential to let the casserole cool to room temperature before sealing it to maintain its texture and prevent condensation inside the container.
Can I freeze the Low Carb Chicken Casserole?
Yes, you can! Portion your casserole into airtight containers and freeze it for up to 3 months.

What should I do if my casserole turns out too watery?
If you find your casserole is watery, that’s often due to excess moisture in the vegetables. To prevent this, ensure to thoroughly drain spinach and par-boil broccoli only for 2-3 minutes. If it still seems watery post-baking, consider serving it with a slotted spoon to drain excess liquid.
