01 - In a medium saucepan set over medium heat, melt the unsalted butter until fully liquefied.
02 - Add the minced garlic to the melted butter and sauté for approximately 1 minute, until it becomes fragrant but avoids browning.
03 - Pour in the heavy cream and bring the mixture to a gentle simmer, ensuring to stir frequently to prevent scorching.
04 - Reduce the heat to its lowest setting. Gradually whisk in the freshly grated Parmesan cheese until it is completely melted and the sauce achieves a smooth, uniform consistency.
05 - Season the sauce with fine sea salt, freshly ground black pepper, and the optional pinch of nutmeg according to your taste.
06 - Continue to simmer the sauce for 2 to 3 minutes, stirring constantly, until it thickens to your desired coating consistency.
07 - Remove the saucepan from the heat and serve the Alfredo sauce immediately over freshly cooked pasta or as desired with other dishes.
