Creating gluten-free mac and cheese is a straightforward process when you follow these simple steps:

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

2. Make the Roux: In a medium saucepan, melt the unsalted butter over medium heat. Once melted, whisk in the gluten-free flour and cook for about 2 minutes until it forms a paste (this is your roux).

3. Add Milk: Gradually whisk in the milk, ensuring there are no lumps. Continue to whisk until the mixture thickens, about 5-7 minutes.

4. Add Cheese: Remove the saucepan from the heat and stir in the shredded cheddar and mozzarella cheese. Keep stirring until the cheese is completely melted and the sauce is smooth.

5. Season: Add garlic powder, onion powder, salt, and pepper to the cheese sauce. Stir well to combine the seasonings evenly.

6. Combine Pasta and Sauce: Add the cooked gluten-free macaroni to the cheese sauce. Stir well to ensure every piece is coated in the creamy sauce.

7. Transfer to Baking Dish (Optional): If you prefer a baked version, transfer the mac and cheese to a greased baking dish. You can sprinkle gluten-free breadcrumbs on top for an added crunch.

8. Bake (Optional): Preheat your oven to 350°F (175°C) and bake for 15-20 minutes or until the top is golden and bubbly.

9. Serve: Remove the macaroni from the oven (if baked) and let it cool slightly before serving.

These steps will guide you in creating a wonderfully creamy and flavorful gluten-free mac and cheese that’s sure to satisfy all.
