Recipe from Cook like a Champion.
-4 tablespoons unsalted butter
-3 garlic cloves, minced
-medium yellow onion, diced
-2 tablespoons tomato paste
-1/2 cup vodka
-1 (28 ounce) can crushed tomatoes
-1 cup heavy cream
-Generous pinch of red pepper flakes
-1 teaspoon salt
-1 pound pasta
-1/2 cup parmesan cheese, plus additional for serving
While the pasta is cooking, melt the butter in a large skillet (or large pot, you will need to add a lot of ingredients) over medium-high heat. Once melted, add the onion and cook about five minutes or until softened.
Next, add the garlic and cook until fragrant, about one minute. Add the crushed tomatoes, bring to a simmer.
Reduce heat and then stir in the tomato paste and vodka. You'll want to cook this until most of the alcohol has evaporated, for 5-7 minutes. Now, stir in the cream, red pepper flakes and salt. Bring to a simmer, then reduce heat. Cook sauce until thickened, about 5 minutes. Stir in the cheese.
