Step‑by‑Step Instructions for Creamy Low Carb Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This crucial step ensures that your Creamy Low Carb Chicken Casserole bakes evenly, resulting in a perfectly cooked dish with a beautifully melted cheese topping. While the oven heats up, you can prepare your baking dish.
Step 2: Prepare the Baking Dish
Grease a 9x9-inch baking dish with cooking spray or a light coating of olive oil to prevent sticking. This creates a non-stick surface, allowing the casserole to come out effortlessly once baked. Set the dish aside while you sauté your vegetables.
Step 3: Sauté the Vegetables
In a large skillet, over medium heat, add a drizzle of olive oil and toss in the broccoli florets, chopped cauliflower, and diced bell peppers. Sauté for about 4-5 minutes, stirring occasionally, until they are tender but still vibrant. Add the chopped spinach last, stirring until it wilts, then remove from heat.
Step 4: Mix the Creamy Sauce
In a mixing bowl, combine the softened cream cheese and sour cream, stirring well until you achieve a smooth consistency. Next, add the heavy cream along with garlic and onion powder, mixing thoroughly. The velvety sauce serves as the heart of your Creamy Low Carb Chicken Casserole, so make sure there are no lumps.
Step 5: Incorporate Chicken and Vegetables
Take your cooked chicken breast and shred it into bite-sized pieces, then fold it gently into the creamy mixture. Incorporate the sautéed vegetables, ensuring they are evenly distributed. This blend of ingredients provides a hearty base for your casserole, bursting with flavor and nutrition.
Step 6: Assemble the Casserole
Carefully pour the cohesive mixture into the greased baking dish, spreading it evenly to ensure it cooks uniformly. As the final touch, sprinkle the shredded cheddar and mozzarella cheeses generously on top. This melty topping will give your casserole a delightful golden brown crust as it bakes.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and let it bake uncovered for 20-25 minutes. Keep an eye on the casserole; when the cheese is melted and slightly golden brown, it’s time to take it out. The bubbly cheese should signal that your Creamy Low Carb Chicken Casserole is ready to impress.
Step 8: Rest and Serve
Once removed from the oven, allow the casserole to sit for 3-5 minutes before serving. This resting time helps the dish set slightly, making it easier to portion. When you serve it, enjoy the comforting blend of flavors and textures that make this recipe a family favorite!

How to Store and Freeze Creamy Low Carb Chicken Casserole
Fridge: Store the casserole in an airtight container for up to 5 days. Make sure it's completely cooled before sealing to maintain freshness.
Freezer: Wrap the casserole tightly with plastic wrap and aluminum foil, or use a freezer-safe container for up to 2 months. This helps preserve the creamy texture and flavors.
Reheating: For the best results, reheat in the oven at 350°F (175°C) for 20-25 minutes, or until heated through. You can also use a microwave, but the oven keeps the Creamy Low Carb Chicken Casserole creamy and delicious.
Thawing: If frozen, thaw overnight in the fridge before reheating to ensure even warming without compromising texture.

Creamy Low Carb Chicken Casserole Recipe FAQs
What should I look for when selecting ingredients for this casserole?
When choosing your ingredients, especially the broccoli and cauliflower, look for vibrant colors and firm textures. Avoid any with dark spots or wilting leaves. Fresh bell peppers should be crisp and free of blemishes, while the chicken should be cooked and shredded evenly for the best flavor integration.
How can I store leftovers of the Creamy Low Carb Chicken Casserole?
You can store the casserole in an airtight container in the fridge for up to 5 days. Make sure to let it cool completely before sealing to maintain its freshness. If you want to enjoy it later, you can freeze it—just wrap it tightly in plastic wrap and foil for up to 2 months.
Can I freeze the Creamy Low Carb Chicken Casserole, and how should I do it?
Absolutely! To freeze your casserole, allow it to cool completely, then wrap it tightly in plastic wrap and aluminum foil to protect it from freezer burn.

What if my casserole turns out watery after baking?
If your casserole is watery, it might be due to excess moisture from the vegetables. To prevent this, make sure to sauté the vegetables until they are tender but not overcooked.

Last but not least, always use full-fat dairy products, as they contribute to a creamier texture and richer flavor.

Yes, if you or your guests have dietary restrictions, make sure to use gluten-free products for the cream cheese and sour cream.
