Cheddar Cheese Sauce ~This 4 ingredient recipe only needs 3-4 minutes to cook and is best started once the water for your noodles starts boiling. Butter, flour, milk and grated cheddar cheese is all you need! This sauce goes great on veggies, in queso, or over macaroni and cheese. Anywhere to want to add a bit of cheddar will do. Sure beats Velveeta! Sorry Velveeta lovers just my opinion.
