Cook the pasta for 2 minutes less than cooking time indicated on the package, drain and set aside.
Meanwhile, heat the olive oil in a Dutch oven or deep skillet over medium heat. Add minced shallot, garlic, and red pepper flakes and cook until softened, stirring constantly so as not to burn. Add in the tomato paste until it starts to caramelize, stirring constantly, about 3 to 4 minutes.
Deglaze the pan with the vodka and scrape all the dark bits off the bottom of the pan.
Add in the crushed tomatoes and simmer until reduced, about 5 to 7 minutes.
Add in heavy cream, ½ cup of parmesan cheese, butter, and salt and stir until the cheese has melted, simmer over low heat for 2 to 3 minutes, stirring frequently.
Remove the sauce from heat and add the pasta to the sauce, stirring so all pasta is evenly coated. Serve with parmesan cheese and basil.
