  • 2 tablespoon unsalted butter
  • 2 teaspoon minced garlic
  • 1/2 cup heavy cream
  • 2 ounces Pamesan Cheese
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper


  • Set pan to medium heat
  • Add butter then minced garlic. Once garlic has browned a little pour in heavy cream. Toss in cut parmesan cheese.
  • Continue to cook until thickened. If too thin add a little more cheese if too thick add a little more cream until the consistency you want is there.
  • Note, if you use the grated parmesan you will have a hard time getting a thicker sauce.


Helpful Recipe Tips

  • Use fresh parmesan it makes a world of a difference. It thickens the sauce better, more flavorful and melts as it should because it's free of a non-caking agent.
  • If using Palmini noodles don't skip the step of adding into a milk based product and letting it soak for a while.
  • If using any water based noodles like zucchini do not heat them up in your sauce. The water will leak into your sauce and destroy it. Heat the zoodles in a separate pan or bowl. Then add them into your sauce. Note, there may still be a presence of water from the noodles but you can control it better.
