2. Heat 2 tablespoons olive oil in a large high-sided skillet over medium-high heat until shimmering. Add the onion and garlic. Cook, stirring occasionally, until just starting to turn golden-brown, about 4 minutes. Add 1/3 cup tomato paste and 1/4 teaspoon red pepper flakes and cook, stirring often, until lightly toasted, about 2 minutes.

3. Add 1 (28-ounce) can whole peeled tomatoes and its juices, 1/2 cup vodka, and 3/4 teaspoon kosher salt. Using a wooden spoon or potato masher, break up the tomatoes into small bits. Bring to a simmer.

4. Reduce the heat to medium-low and simmer until thickened, about 15 minutes. Meanwhile, add 1 pound penne pasta to the boiling water and cook according to the package directions until just al dente, 9 to 11 minutes. Reserve 1 cup of the pasta water, then drain. Meanwhile, pick the leaves from 4 fresh basil sprigs and thinly slice.

5. Scrape the sauce into a blender. Blend until smooth, 30 seconds to 1 minute. Add 1/2 cup heavy cream and pulse until just combined, about 10 (1-second) pulses. (Alternatively, blend the sauce directly in the skillet with an immersion blender, then add the cream and stir until just combined.

6. Return the sauce to the skillet. Add the pasta, Parmesan, and 1/2 cup of the pasta water. Cook over high heat, tossing constantly, until the penne is coated with sauce, about 4 minutes. Add more pasta water 1 tablespoon at a time as needed if the sauce is too thick.

7. Turn off the heat. Taste and season with more kosher salt and black pepper as needed. Serve topped with the basil, more grated Parmesan cheese, and a few grinds of black pepper or red pepper flakes if desired.

Recipe notes

Sauce variation: If you prefer a chunkier sauce, skip blending and just add the cream and remaining ingredients to the skillet.

Storage: Leftovers can be refrigerated in an airtight container for up to four days.
