Ingredients

  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour
  • 2 cloves garlic, finely minced
  • 1 cup whole milk, warmed
  • 1/2 cup heavy cream, warmed
  • 4 ounces cream cheese, cubed, room temperature
  • 8 ounces sharp cheddar, freshly grated (about 2 packed cups)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon Dijon mustard

Instructions
 

Instructions

  • Gently warm the milk and cream until just warm to the touch.
  • Melt the butter in a medium saucepan over medium heat, add the minced garlic, and sauté until fragrant without browning, 30 to 45 seconds.
  • Whisk in the flour and cook, whisking, for about 1 minute until slightly foamy and toasty.
  • Slowly stream in the warm milk and cream while whisking constantly, and cook 2 to 3 minutes until lightly thickened and velvety.
  • Reduce heat to medium-low, add the cream cheese, and whisk until fully melted and smooth.
  • Whisk in the garlic powder, Dijon mustard, smoked paprika, and a pinch of salt and black pepper.
  • Turn heat to low and add the shredded cheddar in small handfuls, whisking until each addition is melted before adding more; keep the sauce warm, not hot.
  • Adjust thickness by simmering gently 1 to 2 minutes to thicken or whisking in a splash of warm milk to loosen.
  • Taste and adjust salt, pepper, and garlic to your liking, then remove from heat.
  • Serve immediately over hot fries with optional toppings.

Notes

Makes about 2 cups. For best texture, freshly grate the cheddar and keep heat low when adding cheese. Whisk constantly to prevent lumps. Store cooled sauce in an airtight container up to 4 days; reheat gently on low, whisking and adding milk as needed. Sauce can be frozen up to 1 month but may slightly separate; whisk in a teaspoon of cold milk off heat to fix. Variations: add extra garlic or roasted garlic paste, stir in hot sauce or cayenne for heat, swap part of the milk for lager for beer-cheese vibes, or mix cheddar with pepper jack for a smoky nacho style. For gluten-free, use a 1:1 GF flour or thicken warm dairy with 2 teaspoons cornstarch mixed with 2 tablespoons cold milk.
