Easiest Tomato Sauce

I feel like stock trader yelling “Buy, buy, buy!!!”, but it’s the tail end of tomato season and I just figured out the best-tasting, easiest sauce I’ve ever made. And good thing, too, after I indulged my “but it’s on sale!” tendencies and bought 63 pounds of tomatoes (in my defense, I thought it was only 40, but nope, 63).

End of tomato season

Since I first tried canning tomatoes based on the National Center for Home Food Preservation process, I’ve been trying to find ways to streamline things. This year was no exception and resulted in the easiest, least messy, most hands-off method yet. So easy that I honestly don’t know why I’d ever do it any other way ever again. Here’s how it works:

Wash tomatoes, quarter, roast, peel, roast some more

Congratulations, you’re done. Once the tomatoes are cooked, you can put them through a food mill or a blender, leave them in chunks, freeze or can them or eat them with a spoon.

Start to finish

The basic difference between this and the NCHFP method, which most every canning or preservation book or website use: oven versus stovetop. And that makes all the difference. I’m talking about one pan, almost no mess, and minimal waste versus multiple simmering pots and pans, bowls of ice water, a mess across my counter, piles of tomato scraps, and hours of splattering and stirring.

Quartered and cored

Yes, I sound a little like that infomercial with the guy who can’t eat a bowl of popcorn and hold a soda at the same time, but I swear, this really is so much easier. This method eliminates the three things I hated most about the traditional method of processing tomatoes:

  • The boiling water/ice water peeling step. It inevitably makes a mess (they never peel easily for me and coring and cutting that little X in whole tomatoes is a pain), takes more time and attention, and means more stuff to clean. I hate cleaning.
  • Less watery sauce in less time. Getting 20 pounds of tomatoes to a good sauce consistency takes a solid half a day on my stove and makes a righteous mess. See above re. cleaning.
  • Constantly being at the stove. Granted, the oven method isn’t totally hands-off, but it requires much less babysitting than a simmering pot. Heck, when I made these last night I put them in the oven then read a book. OMG.

Easy peel

This also tasted better than any other tomato sauce I’ve made. Combining the large surface area of a roasting pan with dry heat of the oven (if you have a convection oven, so much the better) means the water in the tomatoes evaporates faster and more effectively than in a pot simmering on a stove. And that means much more concentrated tomato flavor in less time than it would take on a stove. Plus, especially if you use a large sheet pan like the dark one above, the sugars start to caramelize around the edges as the water cooks off, adding incredible depth, richness, and sweetness to the sauce.

The best, easiest tomato sauce

I’ve already eaten this on pasta, as a base for baked eggs, and finished off that little bowl standing at the counter with a spoon. I cant wait to use this in chili, to make tomato soup with grilled cheese, spaghetti and meatballs….Do you think it would be totally crazy if I bought more tomatoes this weekend?

Easy Tomato Sauce
I’ve used this process for anywhere from 3 pounds to 30 pounds of tomatoes and it works great no matter how you scale it. I don’t add salt to the roasting tomatoes; I find I have better control when it’s added to the final sauce before canning or freezing. And incidentally, if you cook this down long enough, you’ll end up with homemade tomato paste, which is so good.

Heat the oven to 300 degrees.

Wash tomatoes and cut out any bad spots and any bit of core. Halve small tomatoes, quarter large ones.

Put tomatoes in whatever baking sheet or roasting pan you have (4 pounds per large pan works nicely).

Drizzle with a bare minimum of olive oil, add a peeled clove of garlic if you want (if you want to can this, 1 clove per 5 pounds is safe according to the proportions from Ball’s seasoned tomato sauce).

Roast. After an hour or so, take the tomatoes out of the oven and the skins should slip right off.

Continue roasting until they’re cooked down as much as you like. Check on them occasionally, give the pan a shake, make sure nothing is burning in the corners. Do scrape any dark brown caramelized bits back into the tomatoes, this is pure flavor.

For halved or quartered tomatoes: Take tomatoes out of the oven while they still hold their shape pretty well but aren’t swimming in liquid, about 2 hour total.

For crushed tomatoes or sauce: Pour tomatoes through a food mill, process in a blender, or mash with a wooden spoon to your preferred consistency.

For waterbath canning: Pour tomatoes (quartered, crushed, or sauced) into a large pot and bring just to a simmer. Funnel into hot jars and follow the acidification and timing instructions from the NCHFP.

  1. Thus us winderful! I’m such a lazy tomato canner, I never peel them and try to do as few steps as possible with as little mess as possible! So is this sauce tart or sour? I usually have to add some honey or a carrot to add some sweetness to the tomatoes? Do you add anything like that?


    1. To me it isn’t tart at all, since the sugar gets concentrated. But other than the garlic, I keep this unseasoned (salt, sugar, and herbs) so I can adjust it depending on what I’m making.


  2. Hah! Smart Lady, thank you!

    I made a batch of beautiful mahogany colored sauce today. Last week I killed my over the range microwave/fan with steam. Tons of simmering tomatoes = $$ wet electronics. Oy.

    For whatever it’s worth I used great big over ripe juicy beefsteak brandy wine type tomatoes. Purchased cheap by the flat – not sauce varieties.

    Thanks for all your blog posts!


  3. I must try this next year. Right now, I’m plenty supplied with tomato stuffs in jars! There is an easy way to peel tomatoes that does not involve that pesky blanching: just freeze their butts. Then let them sit on the counter for a bit and you can pinch the skins right off them. But I make pizza sauce by pureeing the whole tomatoes with the other stuff in the sauce. No peeling at all, and I like that moist heat in the house in these chilly days. I blogged about both these things, but I’m too lazy to look up the links. . .
