Cook the pasta according to the package directions. It’s important to not overcook it. Gluten-free pasta can get really soggy if overcooked. I rinse it less than 5 seconds under cold water.
12 ounces (3 cups or 340 grams) gluten-free elbow macaroni
Meanwhile, in a medium saucepan over medium heat, melt the butter.
1/4 cup (56 grams) butter
Stir in the flour, salt, pepper and garlic until combined.
3 tablespoons (26 grams) gluten-free baking flour, 1/4 teaspoon salt, 1/4 teaspoon garlic powder, 1/8 teaspoon black pepper
While stirring constantly, gradually add the milk.
2 cups (473 ml) whole milk
Once the mixture starts boiling, turn down the heat to low and let simmer for 1 minute, while continuing to stir constantly.
Slowly add the cheese and stir until totally combined.
1 2/3 cups (188 grams) cheddar cheese, 1/3 cup (33 grams) Parmesan
Add the pasta and stir until totally coated.
Serve immediately.
If you plan to make it in advance, it’s best to keep the macaroni and the cheese sauce separate if you know you’ll be reheating it later.
