Ingredients

  • 1 pound Fettuccine pasta uncooked
  • 6 tablespoons unsalted butter
  • 3 cloves garlic minced (about 1 tablespoon)
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups whole milk
  • 1 1/2 cups heavy cream
  • 1 cup freshly grated Parmesan cheese
  • 1/8 teaspoon nutmeg
  • Salt and pepper to taste
  • 1 tablespoon fresh parsley finely chopped

Instructions

  • Cook the Pasta: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente or to your preferred texture. While the pasta cooks, start making the sauce.
  • Prepare the Sauce: In a large saucepan over medium heat, melt the butter. Once melted, add the minced garlic and sauté 1 minute or until fragrant, stirring frequently to prevent burning.
  • Make the Roux: Reduce the heat to low, then whisk in the flour and cook for about 2 minutes, stirring constantly. The butter and flour will bubble together, forming a smooth base for the sauce.
  • Build the Sauce: Gradually whisk in the milk and heavy cream, stirring continuously to achieve a smooth mixture. Increase the heat to medium and bring the sauce to a gentle boil. It will start to thicken as it simmers.
  • Add the Cheese & Seasonings: Stir in the Parmesan cheese, whisking constantly until it melts completely into the sauce. Season with salt, black pepper, and nutmeg to taste.
  • Combine with Pasta: Drain the fettuccine and immediately add it to the saucepan with the Alfredo sauce. Toss everything together until the pasta is well coated. Don't worry if it looks like a lot of sauce—the pasta will absorb it, and the sauce will thicken as it sits.
  • Finish & Serve: Sprinkle with freshly chopped parsley and serve immediately while hot. Enjoy!
