Follow these straightforward steps to whip up a delicious dinner:

1. Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside.
2. In a large skillet, heat olive oil over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes.
3. Add the minced garlic and red pepper flakes, cooking for an additional minute until fragrant.
4. Pour in the vodka and allow it to simmer for 2-3 minutes, letting the alcohol cook off and the flavors meld.
5. Add the crushed tomatoes, stirring to combine. Let this simmer for about 10 minutes, until the sauce thickens slightly.
6. Reduce the heat to low and stir in the heavy cream, cooking for another 2 minutes to heat through.
7. Add the cooked penne to the sauce, tossing to coat the pasta evenly.
8. Stir in the grated Parmesan cheese, season with salt and pepper, and cook until the cheese is melted and incorporated.
9. Garnish with fresh basil leaves before serving.

Cooking is an art, not a science. If you find your sauce a bit too thick or thin, adjust with more cream or a splash of pasta water. I’ve learned over the years that a little improvisation can lead to some of the best kitchen discoveries.
