Make this smooth, creamy nacho cheese sauce quickly. It uses simple ingredients and is ready in under five minutes, perfect for chips or topping snacks.

Ingredients

Scale
  • 1 tablespoon butter
  • 1 tablespoon all-purpose flour
  • 1 cup 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 and whisking until the sauce thickens slightly, about 2 to 3 minutes.
  4. Remove the saucepan from the heat. Add the shredded cheddar cheese, salt, and cayenne pepper, if using.
  5. Stir until the cheese is completely melted and the sauce is smooth and creamy.
  6. Serve immediately over tortilla chips, tacos, or fries.

Notes

  • Shred your own cheese for the smoothest results; pre-shredded cheese contains anti-caking agents that can make the sauce grainy.
  • If the sauce becomes too thick upon cooling, whisk in a tablespoon of milk or water until you reach your desired consistency.
  • For a flavor similar to Taco Bell nacho cheese sauce, substitute half of the cheddar cheese with Monterey Jack cheese and add 1/4 teaspoon of white vinegar or a dash of mild green chili powder.
