Make this rich and creamy Alfredo sauce using cottage cheese instead of heavy cream. It is a quick, high-protein alternative perfect for a healthy weeknight dinner.

Ingredients

Scale
  • 1 cup low-fat cottage cheese
  • 1/2 cup grated Parmesan cheese, plus more for serving
  • 1/4 cup milk (any kind)
  • 2 cloves garlic, minced
  • 1 tablespoon lemon juice
  • 1/4 teaspoon black pepper
  • Pinch of salt
  • 1 tablespoon butter or olive oil (optional, for richness)
  • 12 ounces pasta (fettuccine or spaghetti recommended)

Instructions

  1. Cook your pasta according to package directions. Reserve about 1/2 cup of the starchy pasta water before draining.
  2. While the pasta cooks, combine the cottage cheese, Parmesan cheese, milk, minced garlic, lemon juice, pepper, and salt in a high-speed blender.
  3. Blend the mixture until it is completely smooth and velvety. This step is key for a traditional Alfredo texture.
  4. If using, melt the butter or heat the olive oil in a large skillet over medium-low heat.
  5. Pour the blended sauce into the skillet. Heat gently, stirring constantly, for 1 to 2 minutes. Do not let it boil.
  6. If the sauce is too thick, add the reserved pasta water, one tablespoon at a time, until you reach your desired consistency.
  7. Toss the drained, hot pasta directly into the skillet with the sauce until fully coated.
  8. Serve immediately, topped with extra Parmesan cheese.

Notes

  • For a Keto or Low Carb option, substitute pasta with zucchini noodles or steamed broccoli florets.
  • To boost flavor, add a dash of nutmeg or a teaspoon of Dijon mustard to the blender.
  • You can make this sauce ahead of time; reheat gently on the stovetop with a splash of milk or water to restore creaminess.
