  • 2 tablespoons butter

  • 1 cup fat free half and half
  • 1 cup parmigianno reggiano cheese freshly grated + more for garnish (optional)

  • Bring large pot of salted water to a boil. Cook desired pasta to al dente and drain. Set aside. While pasta is cooking, grate your parmesan cheese.

  • In a large skillet with high sides, melt your butter and then stir in the flour to create a paste. Cook 30 seconds.
    whisking roux in pan
  • Slowly add the milk into the roux, whisking as you go, until its completely incorporated. Add the minced garlic. After 2-3 minutes of whisking, sauce should simmer slightly and thicken. Pour in the fat free half and half and salt. Whisk again for another minute to warm it through.

  • Once your white sauce has thickened nicely, slowly incorporate the grated parmigiano reggiano cheese in, about 1/4 cup at a time, until its melted smoothly into the sauce. After the cheese has been completely melted in, taste and adjust your seasonings. This sauce has a tendency to seem sweet because of all that dairy and garlic, so don't be afraid to add extra salt because it most likely will need it.
