Making a roux is an essential step for creamy mac and cheese! Start by melting equal parts butter and flour in a saucepan—usually about 2 tablespoons each. Stir constantly over medium heat for about 2-3 minutes until it looks smooth and golden. This simple base thickens your cheese sauce beautifully. Have you tried making a roux before, or is this a first for you? What kind of cheeses are you thinking of using for your mac and cheese?
