01 - In a medium saucepan over medium heat, melt the butter until it begins to foam slightly.
02 - Add the minced garlic and shallot. Sauté for 2–3 minutes until fragrant and translucent, being careful not to brown the garlic.
03 - Pour in the heavy cream, stirring gently to combine with the aromatics.
04 - Bring the mixture to a gentle simmer—do not let it boil. Cook for 5–7 minutes, stirring occasionally, until the cream slightly thickens and coats the back of a spoon.
05 - Stir in the grated Parmesan cheese until completely melted and the sauce becomes smooth and velvety.
06 - Add salt, pepper, and nutmeg. Stir well to distribute the seasonings evenly throughout the sauce.
07 - Remove from heat. Taste the sauce and adjust seasoning with additional salt or pepper as needed.
08 - Toss immediately with hot, cooked pasta of your choice. Garnish with chopped fresh parsley before serving.
