Chef John's penne with vodka sauce is a classic Italian pasta dish with a twist. The penne pasta is cooked al dente and tossed in a creamy tomato sauce infused with vodka. The sauce is made with onions, garlic, tomatoes, cream, and a splash of vodka, which adds a unique flavor to the dish. This pasta is rich, flavorful, and perfect for a special occasion or a comforting weeknight meal. Serve it with a sprinkle of Parmesan cheese and fresh basil for a finishing touch.
