  • Total Time: 20 minutes
  • Yield: Serves 4

Ingredients

Alfredo Sauce Ingredients

  • 12 ounces cauliflower florets (1 small cauliflower)
  • ½ cup grated Parmesan cheese, plus 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, to taste
  • 1 to cups reserved pasta cooking water

Instructions

  1. Boil Cauliflower: Bring a large pot of salted water to a boil. Add the cauliflower florets and cook until fork tender, about 8 to 10 minutes. Drain the cauliflower well.
  2. Combine Ingredients: Place the drained cauliflower in a blender. Add the Parmesan cheese, extra-virgin olive oil, garlic cloves, Dijon mustard, unsalted butter, fresh lemon juice, sea salt, and freshly ground black pepper.
  3. Blend Sauce: Pour in 1 cup of the reserved pasta cooking water and blend the mixture until smooth and creamy. Add more water if needed to reach your desired consistency.
  4. Toss with Pasta: As you mix the Alfredo sauce with cooked pasta, add the remaining ½ cup of pasta cooking water gradually to loosen the sauce if necessary, ensuring a silky and perfect coating.

Notes

  • You can adjust the consistency by adding more or less pasta water.
  • Freshly grated Parmesan cheese works best for optimal flavor.
  • For a dairy-free version, substitute butter with vegan butter and Parmesan with nutritional yeast.
  • This sauce pairs beautifully with fettuccine, penne, or roasted vegetables.
  • Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently with a splash of water.
