Equipment

  • Saucepan
  • Whisk

Ingredients

  • 2 T Butter
  • 1/2 T Garlic Powder or 1 T Crushed Garlic
  • 1/4 tsp. Salt
  • 1/8 tsp. Pepper
  • 3 oz Cream Cheese
  • 1 cup Heavy Cream
  • 1/2 cup Parmesan

Instructions

  • Place the butter and your chosen garlic in a pan over medium heat, stirring as the butter liquefies. The garlic should smell fragrant without developing dark brown spots.
  • Work the cream cheese into the warm butter with steady stirring until no pieces remain. The mixture should look cohesive, with no pale lumps clinging to the spoon or whisk.
  • Stir the heavy cream, Parmesan, salt, and pepper into the cream cheese mixture until evenly blended. Look for a uniform sauce without visible cheese shreds or pockets of seasoning.
  • Maintain a gentle simmer for 5–10 minutes, stirring continuously and adjusting the heat as needed. The finished sauce should feel slightly more resistant to stirring and leave an even coating on a spoon.

Notes

Texture tip: Freshly grate Parmesan from a wedge using a fine grater. Packaged pre-shredded cheese contains anti-caking agents that can cause a sandy, gritty texture.
Heat management: Maintain a gentle simmer with small bubbles rather than a rolling boil. High heat can cause the cheese and butterfat to break into an oily layer.
Reheating: Warm chilled sauce in a small saucepan over low heat while whisking. Add a small splash of heavy cream if it needs to loosen, and avoid high-power microwave heating.
