Tomato Sauce with butter and onion

By Laura77

Another thing that blew my mind about this sauce: I, for one, am a grated parmesan junkie. I not only sprinkle it over my bowl of pasta, I like to have additional nearby, to apply a fresh coat to the layers of pasta that follow. So you can imagine my shock to find that I liked this dish even more without the parmesan. The flavor of the sauce is so delicate, fresh and sweet that it needed nothing at all.

Ingredients

• 28 ounces (800 grams) whole peeled tomatoes from a can (San Marzano, if you can find them)
• 5 tablespoons (70 grams) unsalted butter
• 1 medium-sized yellow onion, peeled and halved
• Salt to taste

Preparation

Step 1

Put the tomatoes, onion and butter in a heavy saucepan (it fit just right in a 3-quart) over medium heat. Bring the sauce to a simmer then lower the heat to keep the sauce at a slow, steady simmer for about 45 minutes, or until droplets of fat float free of the tomatoes. Stir occasionally, crushing the tomatoes against the side of the pot with a wooden spoon. Remove from heat, discard the onion, add salt to taste (you might find, as I did, that your tomatoes came salted and that you didn’t need to add more) and keep warm while you prepare your pasta.

Serve with spaghetti, with or without grated parmesan cheese to pass.

* I liked this enough to make us more the next day, but I only had a can of tomato puree. It also worked well, despite having slightly less texture. You will need a little less simmering time as the tomatoes are already broken down.
