First, the ingredients. You’ll need a 28-ounce can of whole, peeled tomatoes; one peeled, halved onion; and 5 tablespoons of butter. (Yes, 5 whole tablespoons of butter.) You’ll also want a pinch or two of salt.
Put everything together in a single pot and set it to simmer over medium heat on the stove for 45 minutes, uncovered. Give it the occasional stir. And that’s it. After the 45 minutes is up, toss out the onion halves, and pour the sauce over your favorite pasta. Easy.
