Make this smooth and creamy nacho cheese sauce quickly using simple ingredients. This recipe is perfect for chips, fries, or as a topping for tacos.

Ingredients

Scale
  • 1 tablespoon unsalted butter
  • 1 tablespoon all-purpose flour
  • 1 cup whole milk
  • 8 ounces sharp cheddar cheese, shredded
  • 1/4 teaspoon salt
  • 1/8 teaspoon cayenne pepper (optional)

Instructions

  1. Melt the butter in a small saucepan over medium heat.
  2. Whisk in the flour and cook for one minute, stirring constantly to create a roux.
  3. Gradually whisk in the milk until the mixture is smooth. Continue cooking, stirring often, until the sauce thickens enough to coat the back of a spoon, about 3 to 5 minutes. Do not let it boil rapidly.
  4. Remove the saucepan from the heat. Add the shredded cheddar cheese, salt, and cayenne pepper (if using). Stir until the cheese is completely melted and the sauce is smooth.
  5. Serve immediately over your favorite snacks.

Notes

  • Shred your own cheese for the smoothest melt; pre-shredded cheese often contains anti-caking agents that can make the sauce grainy.
  • If the sauce becomes too thick while sitting, whisk in a tablespoon of milk or water until you reach your desired consistency.
  • This recipe makes a great copycat version of fast-food cheese dip.
