Make the rich, creamy, garlic Parmesan Alfredo sauce from Olive Garden at home in just 20 minutes. This recipe delivers restaurant quality flavor using simple ingredients.

Ingredients

Scale
  • 4 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 1/2 cups heavy cream
  • 1 cup freshly grated Parmesan cheese, plus more for serving
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • Pinch of ground nutmeg (optional)

Instructions

  1. Melt the butter in a medium saucepan over medium heat.
  2. Add the minced garlic to the melted butter and cook for about 1 minute until fragrant. Do not let the garlic brown.
  3. Pour in the heavy cream. Bring the mixture to a gentle simmer, stirring occasionally. Reduce the heat to low.
  4. Whisk in the grated Parmesan cheese slowly until the sauce is smooth and the cheese is fully melted.
  5. Season with salt, pepper, and a pinch of nutmeg, if you are using it.
  6. Continue to cook on low for 2-3 minutes, stirring constantly, until the sauce thickens slightly. Do not boil the sauce after adding the cheese.
  7. Serve immediately over hot fettuccine or use as a dip for breadsticks.

Notes

  • For a smoother sauce, use freshly grated Parmesan cheese instead of pre-shredded cheese.
  • If the sauce becomes too thick upon standing, whisk in a tablespoon of milk or reserved pasta water to reach your desired consistency.
  • This sauce pairs well with grilled chicken or shrimp for a complete meal.
