Ingredients

  • 3 Tablespoons unsalted butter (50g)
  • 2 garlic cloves minced
  • ½ onion finely sliced (use red, white, or yellow)
  • 1⅓ pounds zucchini grated (600g)
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1 teaspoon Italian seasoning
  • ¼ teaspoon red pepper flakes
  • 1 cup heavy cream
  • ¾ cup low-sodium chicken stock or vegetable stock or broth.
  • ¾ cup parmesan 75g or 2 ⅔ oz. finely grated using microplane * see notes
  • 10 ounces short pasta such as conchigliette (small shells) ** see notes

Finishing and serving - optional

  • Grated parmesan cheese
  • Fresh basil ribbons, sprinkle of bacon, buttered fresh bread crumbs These options are not included in the nutritional count.

Instructions

Cook Pasta:

  • Bring a large pot of water to boil and add 1 Tablespoon of kosher salt to the water.
  • Cook pasta per package directions to "molto al dente" which is 2 minutes BEFORE the al dente level on the package. The pasta should be a bit too firm. It will finish cooking in the sauce.
  • Save a full ladle of pasta cook water in a large cup and set aside. You' need this for thinning the sauce just in case it's too thick. Drain the pasta.

Zucchini Sauce:

  • Melt the butter in a large skillet or pot over medium high heat.
  • Add the garlic and onion and cook for about 1½ minutes until the onion is slightly golden.
  • Add the shredded zucchini, cook for 1 minute.
  • Add the kosher salt, black pepper, Italian seasoning, and red pepper flakes. Stir for 2 minutes until it reduces in volume by about ½. The zucchini will release liquid.
  • Stir in the cream, chicken stock, and the parmesan cheese. Bring to a simmer, then reduce the heat to medium and simmer for 3 minutes.
  • Add the drained pasta and toss well for 2 minutes, or until the sauce reduces and is coating the pasta instead of pooling in the skillet. If it gets too thick, ad a splash of the reserved pasta cooking water. The pasta will finish cooking in this step.
  • Remove from the stove, serve immediately, garnish with extra parmesan and any other option you'd like.

Notes

**If you grate your own parmesan cheese make sure you weigh the parmesan when measuring. Freshly grated parmesan cheese is much fluffier than store bought. 
  • If using store bought parm (which I usually don't use) add it in the the pasta, don't try to melt it in the sauce because it wont' melt evenly through the sauce. Some cheese have anti-clumping additives included in the packaging and you may end up with cheese that doesn't melt evenly. 
***Use short pasta with nooks and crannies that will capture and hold the sauce. Gemelli and orecchiette pasta are also options.
