Last year I discovered a new way to preserve Roma tomatoes: roasted, in the oven. I’m sure that all of you have access to Romas, either from your garden, your neighbor’s garden, or the Farmers’ Market. My point is, you need to go buy some and then make these tomatoes.
I am not sure what is the best, most efficient way to do these tomatoes—I’m still experimenting. So I’m just going to tell you about the several different methods I have employed. The recipe and method are flexible, so you’ll have to play around with the ingredients yourself. My point is, pretty much anything you try will be fine.
But whether or not you make these tomatoes is non-negotiable. That’s my main point.
First thing: Don’t burn them. But even that is a matter of taste. My mother thinks that anything that has a caramelized flavor tastes burned. I happen to love the caramelized flavor—the bits of the tomato that turn dark brown and chewy. I was able to salvage a small fraction of the tomatoes pictured above. My mother would’ve chucked them all.
Oven-Roasted Roma Tomatoes
I think this is adapted from Barbara Kingsolver’s book, Animal, Vegetable, Miracle, but I’m sadly too lazy to go look it up and double check on that. You ought to read the book anyway. Let me know if you find the recipe there, okay?
A medium-sized bowl of Roma tomatoes
about a cup of chopped, mixed fresh herbs (basil, oregano, thyme, parsley, rosemary)
several cloves of minced garlic
a couple splashes of olive oil, maybe 1/4 cup
a couple splashes of red wine, optional
salt and black pepper
Wash the tomatoes, cut the tops off, and slice them in half, lengthwise. Lay them skin side down on a large cookie sheet that has sides and that has been lined with tinfoil. To make this whole process worthwhile, you’re going to want to fill your oven with as many trays of tomatoes as will fit on your racks, and lay the tomatoes as close together as is possible without them laying on top of each other. They will shrink to about half their original size. I do two big trays at a time, though I would do more if I had more racks for my oven. (Mr. Handsome, can you please help me out here? Find me another two racks?)
Now, there are different methods for the next part. Here’s three of them. Pick one, or create a new one.
In a small bowl, mix together the chopped herbs, garlic, olive oil, red wine, salt, and pepper. Using your fingers, distribute the herb mixture over the tomatoes, making sure that each tomato has received a little dollop of green goodness and juice.
Sprinkle the chopped herbs over the tomatoes. Then the chopped garlic, the salt, and the pepper. Drizzle the olive oil over all, followed by a couple splashes of wine.
Put the prepared tomatoes in a large bowl. Add the olive oil, wine, and garlic and gently toss to coat. Lay the tomatoes out on the trays. Sprinkle the chopped herbs over all.
Another idea, which may become Method #4 in the near future
Prepare them as in method #3, but use herbes de Provence in place of fresh herbs, as in the Tomato Bread Pudding recipe that nearly slayed me.
Last night I lighted on the best way to roast these tomatoes. See, they take a long time in the oven and during the day I often run into trouble because I want to bake granola or bread or potatoes or something and the tomatoes are in there, hogging up all the space. Also, I’ve been roasting them a little too quickly and they’ve been too caramelized (okay, Mom, burned) while at the same time still being a bit too juicy. So last night I turned the oven to 225 degrees right before I went to bed (around 9:30 pm) and they roasted all night long. I could smell them when I got up to go to the bathroom, and that made me smile to myself because I was being productive even while I was sleeping. I checked on them at around 6:15, and only about six halves were too heavily caramelized—the rest were just fine, and about half of them were not quite done. Tonight I’ll set the oven to just 200 degrees.
Pull the tomatoes off the trays, one by one, as they finish roasting, and lay them on a dinner plate. When they are all off the trays and have cooled to room temperature, put them in a quart jar, label it “Roasted Romas ‘08″, and put them in your freezer.
These tomatoes are fabulous in grilled cheese sandwiches, or any kind of sandwich for that matter. They taste rich and warm and darkly tomato-y. Chop them up and add them to pasta dishes, pesto, salads, dips, dressings, and so forth. They will disappear pretty fast, so you better run your oven every night for the rest of the month of August if you plan to have enough to make it through the winter.
Just a suggestion.
Is it 200 degrees overnight? Seems a lot.
Can I double check the overnight oven temperature with you? 200 degrees seems very high to me. For overnight roasting wouldn't the lowest temperature be the thing? Thanks, Anne
It totally depends on your oven, probably—mine is a fussy old thing. You could certainly do it at a lower temp and then, if the tomatoes aren't done in the morning, just boost the temperature and finish cooking them off…
Can these be put into freezer boxes or bags instead of jars? I have used all my jars for canning.
I read the comments – yes, I have had great success roasting any old tomato I get my hands on.
Someone asked what to do with too many cherry tomatoes. This is what I do with my left over little cherry tomatoes. Roast and freeze. Great finger food or used in your recipes!! amazing flavors.
Do you have to freeze them or is there anyway to preserve them without freezing them?
I have no idea. I wonder if they could be pressure canned?
Yes, you can use other kinds, though paste tomatoes are best. They are meatier and less juicy. You can try roasting juice tomatoes, but it might take longer and the resulting tomatoes might taste less tomato-y. But then again, maybe not. I haven't tried it. If you do, let me know!
Has anyone tried roasting other varieties of tomatoes besides Romas? I have plenty of tomatoes but not that many Romas.
Thanks for posting this! I am roasting away as I type! (I harvested 80 lbs of green tomatoes just b4 the first freeze. I've been preserving them as they ripen.)
Have you tried this with a half-tsp or so of pesto per half? (I do a more concentrated pesto than the Simply In Season’s.) I’ve been doing carmelized tomatoes for a long time: this looks yummy. Thanks! – MAC

Oh. My. Word. These are wonderful. Fabulous. I am eating them right out of my oven for breakfast. If you love sun dried tomatoes, you’ll love these. Thanks!!!!!!
Oh, and wood planks measured to the right length work perfectly for additional oven shelving. I was able to get 4 cookie sheets in this way.
Did you ever try convection bake for these tomatoes?
If you have that option, it would probably cut down on the bake time considerably.
I think I will try a small batch.
You Can Call Me Jane
In case you all don’t know, this woman can read minds. I called her this afternoon for this recipe only for her to tell me she just posted it. Thank you, dear, for the recipe, the peppers, the white wine and those fabulous chocolate chip cookies- you should have seen how delighted and MESSY my kids were by the time we got home. I was delighted, too. Just not as messy.:-)
I can’t wait till tonight to set a batch in the oven!
