Melt the Butter:Place a medium saucepan over medium heat. Add the butter and let it melt completely, ensuring it doesn’t brown.
Sauté the Garlic:Once the butter is melted, add the minced garlic. Stir and sauté for about 1 minute until fragrant. Be careful not to burn the garlic, as it can turn bitter.
Add the Cream:Slowly pour in the heavy cream while whisking. This helps to incorporate the butter and cream smoothly.
Season the Sauce:Add salt, black pepper, and nutmeg (if using). Stir to combine.
Simmer and Thicken:Bring the mixture to a gentle simmer. Allow it to cook for 4-5 minutes, stirring occasionally. The sauce will start to thicken as it heats.
Incorporate the Parmesan:Gradually add the grated Parmesan cheese, whisking continuously to melt it into the sauce. Ensure the cheese is fully incorporated for a silky texture.
Taste and Adjust:Taste the sauce and adjust the seasoning if necessary. Add more salt, pepper, or nutmeg to suit your preferences.
Serve and Garnish:Remove the sauce from the heat and use it immediately. Sprinkle with freshly chopped parsley before serving for a pop of color and freshness.
