Ingredients

Units Scale

Sauce Ingredients

  • 2 Tbsp. butter
  • 4 garlic cloves, grated with a microplane
  • 2 Tbsp. all-purpose flour
  • 2 cups half and half (not fat free)
  • Zest of 1 lemon, about 1 tsp.
  • 2 Tbsp. fresh lemon juice
  • 1/3 cup grated Parmesan cheese
  • 1 Tbsp. finely chopped parsley
  • Kosher salt and fresh black pepper to taste

Instructions

  1. Melt Butter and Cook Garlic: In a 12-inch non-stick skillet, melt butter over medium heat. Add grated garlic and cook for 30 seconds or until fragrant, stirring constantly to prevent burning.
  2. Add Flour and Cook: Stir in all-purpose flour and cook for 1 minute until lightly golden, stirring constantly to remove the raw flour taste without burning.
  3. Incorporate Half and Half and Season: Gradually pour in the half and half while stirring. Season with kosher salt and fresh black pepper to taste. Reduce heat to medium-low and cook until the sauce thickens, about 1-2 minutes. Whisk out any lumps to ensure a smooth consistency, and the sauce should coat the back of a spoon.
  4. Add Lemon and Cheese: Whisk in fresh lemon juice and lemon zest. Stir in the grated Parmesan cheese and chopped parsley; the cheese will immediately melt into the sauce. Serve immediately over pasta or use as a base for other dishes.

Notes

  • For a smoother sauce, grate garlic and Parmesan cheese using a microplane for better texture and melting quality.
  • This recipe yields about 2 cups of sauce, enough to coat 8 ounces of dry pasta.
  • Leftovers may thicken when standing; thin with white wine, reserved pasta water, milk, or additional half and half as needed.
  • Store leftovers in an airtight container for up to 5 days in the refrigerator.
