Making Comforting Gluten-Free Holiday Mac and Cheese is as easy as pie if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the gluten-free elbow macaroni and cook according to the package instructions until al dente. Drain and set aside.

1. Make the Cheese Sauce: In a large saucepan over medium heat, melt the butter. Once melted, whisk in the gluten-free flour until smooth, creating a roux.

1. Add the Milk: Gradually whisk in the whole milk, stirring continuously to avoid lumps. Continue to cook until the mixture thickens (about 5-7 minutes).

1. Incorporate the Seasonings: Stir in the garlic powder, onion powder, mustard powder, salt, and black pepper into the thickened milk mixture.

1. Melt the Cheese: Remove the saucepan from heat and add the shredded cheddar and mozzarella cheese, stirring until melted and creamy.

1. Combine Pasta and Sauce: Add the cooked elbow macaroni to the cheese sauce, stirring thoroughly to coat the pasta evenly.

1. Transfer to Baking Dish: Pour the mac and cheese into a greased 9×13-inch baking dish. Smooth out the tops for even baking.

1. Add the Breadcrumbs: If desired, sprinkle gluten-free breadcrumbs over the top of the mac and cheese for a crunchy texture.

1. Bake the Dish: Preheat the oven to 350°F (175°C). Bake for 20 minutes, or until bubbly and golden on top.

1. Serve and Enjoy: Once baked, let it sit for a few minutes before serving. Garnish with chopped fresh parsley for a pop of color.

Following these steps will guide you in creating a comforting gluten-free holiday dish that everyone will adore. Enjoy the warmth and love that comes with every bite of this amazing mac and cheese!
