How to Make Creamy Low Carb Chicken Casserole

Preheat Oven: Set your oven to 375°F (190°C) while you prepare your ingredients. Greasing a 9×13 inch casserole dish now will ensure an easy cleanup later.
Cook Veggies: In a skillet, sauté minced garlic until fragrant. Then, add thawed spinach and cook until the moisture evaporates, about 3-4 minutes. This helps to avoid a soggy casserole.
Mix Casserole Base: In a large bowl, combine the cooked chicken, broccoli florets, sautéed spinach, ranch dressing, half of the cheddar cheese, and half of the mozzarella cheese. Stir gently until everything is well-coated.
Assemble: Pour the cheesy mixture into your greased casserole dish, spreading it out evenly. Top it off with the remaining cheeses and crispy turkey bacon for an extra flavor kick.
Bake: Place the casserole in your preheated oven and bake uncovered for 20-25 minutes. Look for the cheese to be melted and bubbly, with golden edges that promise deliciousness.
Serve: Allow your casserole to rest for about 5 minutes before slicing. This helps the flavors meld together beautifully, making it easier to serve.

Optional: Garnish with fresh parsley for a pop of color before serving.

Creamy Low Carb Chicken Casserole Recipe FAQs

What type of chicken is best for this casserole?
For this creamy low carb chicken casserole, I recommend using cooked chicken breast, as it’s the main protein source. Shredded rotisserie chicken is an excellent time-saver since it doesn’t require any cooking and is already flavorful. However, any cooked chicken will work, including grilled or baked chicken, as long as it is tender and easy to shred.

How long can I store leftovers in the fridge?
Absolutely! You can store leftovers of this delicious casserole in an airtight container for up to 3 days. Just make sure to let it cool completely before sealing it up to help maintain freshness. When you’re ready to enjoy again, simply reheat in the microwave or oven until it’s heated through.

Can I freeze the casserole, and how do I do it?
Yes, you can freeze this creamy low carb chicken casserole! To do this, assemble the unbaked casserole and tightly wrap it in plastic wrap followed by aluminum foil to prevent freezer burn. It will maintain its quality for up to 2 months in the freezer. When you’re ready to bake it, you can either thaw it overnight in the refrigerator and bake as usual, or bake directly from frozen, adding an extra 10-15 minutes to the baking time at 375°F.

What should I do if my casserole turns out watery?
If you find yourself facing a watery casserole, there are several steps you can take. Firstly, ensure your spinach is thoroughly thawed and well-drained; any excess moisture here can really affect the end result. If you’re still concerned, consider incorporating a thickener like a bit of cream cheese or even some almond flour to help absorb the excess liquid. Cooking the spinach longer to evaporate moisture is another handy trick!

Are there any dietary considerations for this recipe?
This creamy low carb chicken casserole is perfect for those following a keto-friendly or low-carb diet. However, if you have dietary restrictions, you can easily customize it. For a dairy-free version, substitute the cheese with dairy-free alternatives and choose a cashew-based dressing instead of ranch. If you have concerns about specific allergies, be sure to check all ingredient labels, especially for bacon, cheeses, and any pre-packaged ranch options.

Can I add different vegetables to the casserole?
Very! Feel free to customize your creamy low carb chicken casserole with additional vegetables to enhance flavor and nutrition. Veggies like zucchini, bell peppers, or even cauliflower rice are wonderful additions. Just sauté or blanch them lightly before mixing them in, so they blend nicely with the creamy base and don’t release too much moisture during baking.
