Step 1: Place a large skillet or saucepan over medium-low heat and melt the butter slowly until it begins to foam.
Step 2: Add the minced garlic to the melted butter and sauté for about 1 minute, ensuring it stays translucent and does not brown.
Step 3: Pour in the heavy whipping cream and whisk gently. Bring the mixture to a very light simmer for 3-5 minutes until it begins to slightly thicken.
Step 4: Reduce the heat to low. Add the grated Parmesan cheese one handful at a time, whisking continuously until the cheese is completely melted and the sauce is smooth.
Step 5: Stir in the ground nutmeg, salt, and black pepper. Taste and adjust seasonings as needed.
Step 6: Remove from heat immediately and toss with your favorite cooked pasta, adding a tablespoon of pasta water if the sauce is too thick.
