Bring a large pot of water to a rolling boil. Add 2 tablespoons kosher salt and 8 ounces cavatappi pasta, stir and cook for 1 minute less than the package directs. This is usually about 9-11 minutes. Drain, reserving 1 cup of pasta water.
Add 1 tablespoon unsalted butter and 1 tablespoon extra virgin olive oil to a large skillet. Turn the heat to medium and allow the butter to melt. Once melted, add 3 cloves garlic (minced) and 1 teaspoon Italian seasoning and toast for 30 seconds.
Slowly add ¾ cup heavy cream to the skillet, whisking into the butter and seasonings. Bring to a low simmer, reduce the heat to medium-low and continue to cook, stirring often, until the sauce is slightly thickened. ~2-4 minutes
Add ½ cup grated parmesan cheese½ teaspoon kosher salt, and ½ to 1 teaspoon finely ground black pepper, into the cream sauce, stirring to incorporate. Add the cooked pasta and ¼ cup of the reserved pasta water to the skillet, tossing to coat. Turn the heat to medium and stir constantly, until the sauce is creamy and coats the pasta. If needed, add additional reserved pasta water, 1 tablespoon at a time, iif the sauce seems too thick.
Remove from the heat and let sit for 1-2 minutes before serving. Serve with additional parmesan cheese and minced fresh parsley.
