Learn how to make Alfredo sauce at home! The rich, creamy sauce is delicious over pasta, roasted vegetables, and more.


  • 12 ounces cauliflower florets, (1 small cauliflower)
  • ½ cup grated Parmesan cheese, more for serving
  • ¼ cup extra-virgin olive oil
  • 2 garlic cloves
  • ½ teaspoon Dijon mustard
  • 3 tablespoons unsalted butter
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon sea salt
  • Freshly ground black pepper
  • 1 to 1½ cups reserved pasta cooking water


  • Bring a large pot of salted water to a boil. Add the cauliflower and boil until the cauliflower is fork tender, 8 to 10 minutes. Drain and place the cauliflower in a blender. Add the Parmesan cheese, olive oil, garlic, mustard, butter, lemon juice, salt, and several grinds of pepper.
  • Add 1 cup of the pasta water to the blender and blend the sauce until creamy.
  • As you toss your alfredo sauce with pasta, you may want to add the additional 1/2 cup pasta cooking water to loosen the sauce.
