Welcome to My Kitchen! I’m Carla Davis, and I created this recipe to bring soulful, comforting food back to your everyday table without the stress. This cottage cheese Alfredo sauce delivers the rich, velvety texture of classic Alfredo but is packed with protein and lower in fat. It comes together fast in your blender, making it perfect for quick weeknight dinners.

Ingredients

Scale
  • 1 cup low-fat cottage cheese
  • 1/2 cup milk (any kind)
  • 1/2 cup grated Parmesan cheese, plus more for serving
  • 2 cloves garlic
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 tablespoon butter or olive oil (optional, for richness)
  • 8 ounces fettuccine or your favorite pasta

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, milk, Parmesan cheese, garlic, salt, and pepper in a high-speed blender. Add the butter or olive oil if you are using it.
  3. Blend the sauce mixture until it is completely smooth and creamy. This usually takes about 30 to 60 seconds. Stop and scrape down the sides as needed.
  4. Pour the sauce into the empty pasta pot over low heat. Stir constantly until the sauce is heated through. Do not boil.
  5. If the sauce is too thick, slowly add the reserved pasta water, one tablespoon at a time, until you reach your desired consistency.
  6. Drain the cooked pasta and add it directly to the pot with the sauce. Toss everything together until the pasta is fully coated.
  7. Serve immediately with extra grated Parmesan cheese on top.

Notes

  • For a low-carb option, toss this sauce with zucchini noodles (zoodles) or steamed broccoli instead of pasta.
  • If you want a richer flavor, sauté the garlic in the butter/oil for one minute before adding it to the blender.
  • This sauce is excellent for meal prep; it may thicken slightly upon refrigeration and require a splash of milk or water when reheating.
