Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or avocado oil spray.

Step 2: Make the Alfredo Sauce

In a saucepan over medium heat, melt the butter. Add minced garlic and cook until fragrant (about 1 minute). Stir in the cream cheese until softened.

Add the heavy cream, almond milk, onion powder, and nutmeg. Simmer for 5 minutes, stirring occasionally until the sauce thickens slightly.

Step 3: Add Cheese

Whisk in the parmesan and mozzarella cheeses. Keep stirring until melted and smooth. Season with salt and pepper.

Step 4: Assemble the Casserole

In a large mixing bowl, combine shredded chicken, steamed cauliflower, and Alfredo sauce. Mix well until everything is coated.

Step 5: Bake It

Transfer the mixture to your greased baking dish. Sprinkle a bit of extra mozzarella on top. Bake for 20-25 minutes until bubbly and golden on top.

Step 6: Garnish and Serve

Let cool for 5 minutes. Top with chopped parsley. Serve hot and enjoy!
