Make a smooth, restaurant-style nacho cheese dip at home in under 10 minutes using simple ingredients. This versatile sauce is perfect for nachos, fries, or as a party dip.

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 to create a smooth paste (a roux). Cook for one minute, stirring constantly.
  3. Slowly whisk in the milk until the mixture is smooth and begins to thicken slightly. Continue cooking until the sauce coats the back of a spoon, about 3 to 4 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 continuously until the cheese is completely melted and the sauce is smooth and velvety.
  5. If the sauce is too thick, add a splash more milk until you reach your desired consistency.
  6. Serve immediately over nachos, fries, or use as a dipping sauce.

Notes

  • Shred your own cheese for the best melting quality; pre-shredded cheese often contains anti-caking agents that can make the sauce grainy.
  • For a spicier dip, increase the cayenne pepper or add a dash of hot sauce.
  • If you are planning your weekly meals, this sauce is a great addition to your meal planning for game day snacks.
