Pasta with Fresh Tomato Sauce
Published: October 1, 2010
Time: 20 minutes
Salt
3to 5 tablespoons butter or olive oil
1 1/2pounds tomatoes, roughly chopped
1 pound linguine or other long pasta
1/2 cup shredded fresh basil leaves, if desired
Freshly grated Parmesan, if desired.
1. Bring a large pot of water to a boil and salt it. Put the butter or oil in a large skillet over medium heat; when the oil is hot or the butter’s foam subsides, add the tomatoes.
2. Cook, stirring occasionally, until the tomatoes break up, about 10 minutes, adding salt and freshly ground black pepper to taste. Meanwhile, cook the pasta until done; drain.
3. Toss together pasta and sauce, along with basil and Parmesan, if you like. Taste and adjust the seasoning and serve.
