  • 6 Tablespoons butter high quality
  • 1 Tablespoon garlic minced
  • 2 Tablespoons all-purpose flour
  • 1 ½ cups milk
  • 1 ½ cups heavy cream
  • ½ cup Parmesan cheese grated and at room temperature
  • ½ cup Romano cheese grated and at room temperature
  • Salt and black pepper to taste
  • 1 lb. Fettuccine
  • Parsley to garnish


  1. Boil the fettuccine according to package instructions. As the water preheats, begin the sauce.
  2. Melt the butter in a large saucepan over medium heat. Add the garlic and cook for one minute.
  3. Whisk in the flour. Gradually add the milk and heavy cream, whisking constantly.
  4. Reduce the heat to low once the sauce begins to bubble. It will continue to thicken as it simmers.

  5. Slowly sprinkle in the cheeses, continuing to whisk.

  6. Drain the pasta and carefully mix it into the sauce until well incorporated. The pasta will absorb the sauce an it will get thicker still.
  7. Garnish with chopped parsley, and serve!

Recipe Notes

Note: You may be tempted to add more cheese to thicken to sauce, but it continues to thicken upon standing and even when added to the pasta.

Alfredo sauce is generally thinner than you may think and thickening it further may make it too rich.
