Step 1: Cook the Fettuccine Pasta

1. Bring a large pot of water to a boil over high heat. Add the salt to season the water.
2. Cook the fettuccine according to the package instructions until al dente (firm to the bite). Reserve 1 cup of pasta water, then drain the pasta and set aside.

Step 2: Make the Alfredo Sauce

1. In a large skillet or saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute, or until fragrant.
2. Pour in the heavy cream and stir gently. Bring the mixture to a gentle simmer and cook for 2-3 minutes, allowing the cream to thicken slightly.
3. Gradually whisk in the Parmesan cheese, stirring constantly until the cheese is fully melted and the sauce is smooth.
4. Season with salt, black pepper, and a pinch of nutmeg (if using). Taste and adjust the seasoning as needed.

Step 3: Combine the Pasta and Sauce

1. Add the cooked fettuccine to the skillet with the Alfredo sauce. Toss gently to coat the pasta evenly with the sauce. If the sauce is too thick, add the reserved pasta water, 1-2 tablespoons at a time, until the desired consistency is achieved.

Step 4: Serve and Garnish

1. Divide the Fettuccine Alfredo among serving plates.
2. Garnish with additional Parmesan cheese, freshly cracked black pepper, and chopped parsley.
3. Serve immediately and enjoy!
