Cook the pasta. Bring a large pot of salted water to a boil and cook the pasta according to package instructions until al dente. Right before draining, reserve about ½ cup of the pasta water.
8 oz pasta
Sauté the aromatics. Heat the olive oil in a large skillet over medium heat. Add the diced shallot and minced garlic and cook for about 3 minutes, stirring frequently, until softened and lightly golden. The garlic should turn golden but not brown.
1 tablespoon olive oil, 1 shallot, 3 cloves garlic
Caramelize the tomato paste. Add the tomato paste to the skillet and let it cook undisturbed for 1 to 2 minutes before stirring. Stir, then continue cooking for another minute until the tomato paste darkens slightly and becomes deeply fragrant.
¼ cup tomato paste
Deglaze with vodka. Pour in the vodka and use a wooden spoon or spatula to scrape up any browned bits from the bottom of the pan. Let the vodka simmer for about 1 to 2 minutes.
⅓ cup vodka
Add the milk and parmesan. Lower the heat and slowly whisk in the whole milk and salt until smooth and uniform. If using butter, stir it in now. Let the sauce gently simmer with light bubbles until slightly thickened, about 3 to 5 minutes. Stir in the parmesan cheese until melted.
1 cup whole milk, 1 teaspoon kosher salt, 1 tablespoon salted butter, ¼ cup freshly grated Parmesan cheese
Combine the pasta and sauce. Add the cooked pasta directly into the sauce along with about ¼ cup of the reserved pasta water. Toss continuously until every noodle is coated in the creamy sauce.
Adjust the consistency and serve. Add more reserved pasta water as needed to loosen the sauce. Serve, then top with additional parmesan cheese and fresh parsley.
