The addition of cream and butter heightens this simple tomato sauce without making it heavy. It's special but not extravagant, a wonderful choice for any night of the week.

Direction

1. Gather the ingredients.
2. Melt butter in a large Dutch oven over medium. Add onion; cook, stirring occasionally, until tender and golden brown, about 5 minutes.
3. Add tomatoes and their juices; bring to a boil over medium.
4. Reduce heat to medium-low; simmer, stirring occasionally, until flavors meld and sauce thickens, about 30 minutes.
5. Meanwhile, cook pasta in salted water according to package directions for al dente. Drain pasta, reserving 1/2 cup pasta cooking liquid.
6. Stir cream, salt, black pepper, and crushed red pepper into tomato sauce. Add cooked pasta and toss to coat.
7. Add reserved pasta cooking liquid, 1/4 cup at a time, until desired consistency is reached.
