Marcella Hazan's Tomato Sauce with Onion and Butter
Every Wednesday, Food52's Senior Editor Kristen Miglore is unearthing recipes that are nothing short of genius. This week: the most famous tomato sauce on the internet, from Marcella Hazan's Essentials of Classic Italian Cooking.

It was only a matter of time. The sauce was always there, seeping into every discussion of this whole genius recipe premise. It might even be the reason we hatched the column at all.
Because all you do is simmer tomatoes for 45 minutes with butter and an onion. The full, true tomato flavor is a revelation in itself -- as is finding out you don't need to cook in all those layers of garlic and herbs and whatnot to get there (and you might even be better off without them).
How fitting that this should come to us from Marcella Hazan -- who, with her husband and writing partner Victor, has been credited with making simple, good Italian food accessible to American cooks ever since the publication of her first cookbook in 1973.
Admittedly, this sauce won't be news to a lot of you. Many of our favorite bloggers already had beautiful epiphanies about it years ago. In fact, we could even play a game: Where were you when Obama was elected? ... When you heard Gourmet was folding? ... When you first tried the sauce?
My initiation came late. It was last August, and my CSA was heaving flats full of bursting yellow tomatoes on us. It was too much. It was glorious. And we're already coming up on that tomato tipping point again.

In a few months, we'll be giving the evil eye to $15/pound heirlooms shipped in from warmer climes -- but as of this moment, the farmers markets around here are fully armed with tomatoes in all colors and sizes. You could run through Union Square, pelting aggressive Greenpeace pamphleteers with warm, delicious rainbow pulp. Or you could leave me with my fantasies and gingerly gather up as many as you can, and turn them into sauce that tastes like pure summer, to stock your freezer and get you through gray months to come.
And to me that's the most exciting thing about the sauce. Most bloggers have zeroed in on the fact that Hazan's recipe is tailor-made for a 28-ounce can of San Marzano tomatoes. It does make an excellent year-round sauce that way and is outrageously convenient. But fresh tomatoes are really just better.
Inevitably, they'll require one extra, rather satisfying step: peeling. There are a few ways you can attack this tomato prep, depending on whether you have a food mill, your disposition toward said food mill, and whether you feel like boiling water or not.
Food mill lovers:
1. Halve tomatoes and warm them briefly in a covered saucepan before passing through a food mill, leaving all the bits and scraps behind.
Food mill haters/abstainers:
2a. Boil the tomatoes for a minute, with an X cut in the bottom if you want to show off. Peel like a slippery banana. Chop rustically.
2b. Newly learned, via David Tanis via The Kitchn: Stick your tomatoes in the freezer. As they freeze, the water in the tomato's network of cells expands and bursts the cell walls -- terrible texture for a caprese salad or pico de gallo, but here they'll be getting broken down into sauce anyway, so that's okay. Then, as they thaw, they get slumpy and the skins slip off easily. No boiling and no food mills!
You then simmer away with the swirling butter and bobbing onion, till "the fat floats free from the tomato" -- which of course you should just stir back in. Then Hazan has you discard the onion, but I think you should actually eat it. Chopped up, it would make a fine relish for a grilled Italian sausage -- a Marcella-worthy hot dog onion sauce.
And the rest, as they say, is just gravy. There, I think I just cured your seasonal affective disorder.

I would like to make a spaghetti sauce with cooked sausage in it. Could I can this in canning jars for gifts in a basket? Would rather not freeze if I don't have to.

If you are an experienced canner, and have a pressure CANNER (not a pressure cooker - it's a different piece of equipment,) and you have a trusted sauce recipe designed for canning, the answer is yes.

Even with the butter in it?

Totally agree with you, Kristen, you should eat the onion. Made this using a box of Pomi chopped tomatoes. So delicious. The stewed tomato-y onion was perfect with a generous grating of Parmigiano.
FYI, this sauce is the bomb on top of roasted spaghetti squash, all covered with cheese. Parmigiano, that is.

The recipe even is TAILORED PERFECTLY???????? to A 28oz CAN of good-quality tomatoes -
USE 2 CUPS CANNED IMPORTED ITALIAN TOMATOES, cut up, with their juice!
LAST TIME I LOOKED 2 CUPS = 16 oz NOT 28 oz.
PLEASE EMAIL RESPONSE. WHAT DO I DO WITH OTHER 12 oz ?
I certainly can use it for something else, BUT, THE POINT IS don't say a 28 oz can IS TAILORED PERFECTLY !!!!!!

Hey Frank -- a 28-ounce can is 28 ounces by weight, which turns out to be close to 2 cups, once chopped. And anyways, why be so angry about it?

I buy tomato sauce in the can to use to add to many of my Puerto Rican dishes. Is this sauce a spaghettis sauce, since all are writing that that is how they have used it, or can I use this as a tomato sauce for my receipes?

Yes, you can use this anywhere you would use a tomato sauce! It has a very straightforward, pure tomato flavor.

After reading all the rave reviews, we were very excited to try this recipe. We were fortunate enough to have locally grown San Marzano tomatoes, however, we were disappointed by the results. This recipe was only "good" at best - certainly not worthy of all the hype.

Hi. We made this recipe for years before discovering its simple secrets. The tomatoes must go through the fine blade of the food mill for best results. The onion should not be too big or impacts the flavor. And, most importantly, the sauce should be simmered at a reasonable pace. Occasionall bubbles in the simmer will not work. And, simmer it until it is quite thick, then, put in your wet pasta and a touch more pasta water if it is still too thick. The result is a wonderful, dense, very red film of tomato sauce on the pasta.

Lovely sauce---but it's all about the tomatoes. If fresh, they should be impeccable. Late summer/early fall tomatoes in northern New England have a lot of liquid and may take a bit longer to cook down to the proper consistency. (I used a combination of Opalka paste tomatoes and some heirlooms that needed using up.) To compensate for not having San Marzanos growing up the slopes of an Italian villa, I added a tablespoon of tomato paste and cooked the sauce 15 minutes longer. The result was delicious and almost helped me to forget that temperatures dropped into the forties last night (September 11) for the first time since early May.

I have been making this sauce for many years. I thought that what was "genius"about this recipe was the way you could transform a can of San Marazano tomatoes into an amazing sauce with this method. I have never used it to make sauce from scratch...too much added fat.

great sauce, but an even fresher tasting one: big sautee pan, the bigger the better because you want it to reduce quickly so you don't lose any of that fresh tomato taste. glugs of olive oil. sautee slivers of garlic (lots) until just barely beginning to take on color. dump in lots of fresh tomatoes, skins on, diced (works with canned tomatoes in a pinch, but fresh is best). on high heat, simmer just until tomatoes collapse, reduce a bit and become saucy. during simmer, salt to taste and add a bit of sugar. it will be a sauce with small lumps of tomato in it. turn off heat, add handfuls of fresh, torn basil. if adding rosemary,add at beginning with tomatoes. now that's fresh.

Just wondering if you're supposed to use unsalted or salted butter. And what type of onion? White..vidalia...yellow...there are too many choices in the grocery store! Thanks!

Has anyone tried making this using a can of san marzano? or would it require 2-28oz peeled whole tomatoes? thanks.

I cooked this up last night for dinner with whole wheat pasta and a salad. It was so simple, and so delightful. I brought leftovers to work for lunch today. Awww, such delicious pleasures! Grazie!

Thanks for the reminder! This is one of my favorites for all the reasons mentioned above. I will definitely be going to the farmer's market this weekend!

So ... butter = can this be successfully canned? Anyone? Anyone?

I love this sauce! I've been making it for years. I don't discard the onion though. I actually dice it BEFORE cooking and just leave it in. It's hard to believe so few ingredients have so much flavor. You're right, Kristin, it's genius!
