Instructions to Prepare Low Carb Chicken Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or non-stick spray to prevent sticking and make cleanup easier.

Step 2: Prepare the Vegetables

Steam the broccoli (or cauliflower) for about 3–4 minutes, just until tender but still firm. Overcooking can make the casserole watery, so keep the veggies slightly crisp.

Step 3: Make the Creamy Sauce

In a medium saucepan over low heat, melt butter and add softened cream cheese. Stir continuously until smooth and creamy. Gradually pour in the heavy cream, whisking until well combined. Add garlic powder, onion powder, salt, pepper, and paprika. Continue stirring for 2–3 minutes until the sauce thickens slightly.

Step 4: Combine Chicken and Vegetables

In a large mixing bowl, add the cooked chicken, steamed broccoli, and optional spinach. Pour the creamy sauce over the top and toss until everything is evenly coated. Mix in half of the shredded cheddar cheese for extra creaminess.

Step 5: Transfer to Baking Dish

Pour the mixture into your prepared baking dish, spreading it evenly with a spatula. Sprinkle the remaining cheddar and mozzarella cheese on top to form a golden, bubbly crust.

Step 6: Bake

Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese on top is fully melted and slightly browned. The casserole should be hot and bubbling around the edges.

Step 7: Cool Slightly Before Serving

Remove from the oven and let it rest for about 5 minutes before serving. This allows the casserole to set and makes it easier to slice.
