  • 2 tablespoons salted butter
  • 2 large garlic cloves
  • 2 cups heavy whipping cream
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 1/2 cup freshly grated Parmesan cheese plus extra for serving
  • 1/2 cup freshly grated Romano cheese
  1. Melt your butter in a 2-quart sauce pan over medium-high heat. Press your garlic and add it to the melted butter, stirring a bit. Let it cook for 30 seconds, being careful not to let the garlic burn.

  2. Lower the heat to medium and stir the cream into your garlic mixture. Add your salt and pepper and stir to combine.
  3. Let the cream come to a low boil, while stirring frequently.
  4. Then lower the heat and let the pot simmer, stirring frequently, for 8-10 minutes, or until the cream thickens. It should be thick enough to coat the back of a spoon.
  5. Turn off the heat and move your Alfredo pot to a cool burner. Gradually stir in your fresh Parmesan and Romano.
  6. Place the pot over low heat and stir until the sauce is thickened further. It is done when you push your spoon along the bottom of the pan and can see the bottom of the pan. It will take a few minutes.
  7. The sauce will thicken even more as it sits.
  8. Store leftovers in the refrigerator for up to four days.
Recipe Notes

It's important to use freshly grated Parmesan and Romano, so the cheese will melt smoothly. (Don't use the cheese sold in a can, or the sauce will be grainy.)

This sauce makes enough for one pound of pasta. You can easily cut the sauce recipe in half for 8 ounces of pasta. Note that your sauce will take less time to come to a boil and thicken.

To reheat leftover Alfredo pasta, drizzle on a little olive oil before microwaving it, so the pasta isn't dry.
