Introduction: Roasted Tomatoes

About: I've been posting Instructables since the site's inception, and now build other things at Autodesk. Follow me for food and more!

Slow oven-roasting turns damaged, mediocre, or tasty-but-extra tomatoes into something wonderful.

This is a great way to reduce the volume of your massive tomato harvest for storage!  I buy lots of incredible heirloom tomatoes from Wild Boar Farms* each summer, and roast them to remove water (heirloom tomatoes are VERY wet) and concentrate their flavor.   Then they go into the chest freezer for off-season use in other dishes.



*Like the look of the tomatoes you see in these pictures?  You can buy seeds online at the Wild Boar Farms website.  If you grow tomatoes, I can't recommend their stock highly enough.

Step 1: Prepare Tomatoes

Acquire lots of delicious tomatoes. These are from a box of fabulous heirloom tomatoes from Wild Boar Farms at my local farmers' market. Because I'm cheap I got a box of seconds, meaning that they taste just as good but are aesthetically imperfect or got dinged in transit or handling sometime today. The squished/dinged/leaky tomatoes need to be used immediately to avoid spoilage.

Chop small tomatoes in half, and slice larger tomatoes in thirds or quarters. Lightly coat your baking dish in oil; I use spray canola for this part because I'm lazy and these heirloom tomatoes carry so much liquid they don't need more oil on the bottom.

Place your tomatoes in a single layer in the baking dish, then drizzle with extra virgin olive oil. Sprinkle with salt, pepper, and spices; here I used chopped fresh rosemary and dried oregano. Optional: stick garlic cloves in any remaining spaces to roast and do some serious flavor-trading.

Important storage notes: refrigeration kills off proper tomato flavor. Keep them on your counter, and check daily for softness or incipient mold. Don't wash them until you're ready to use them.

Step 2: Roast Tomatoes

Put your tomatoes in a 300F oven and wander off for a bit.

Depending on the thickness of your slices and the amount of water in the tomatoes, time will vary. You can follow the smell; there will be a gorgeous roasty aroma as the tomatoes cook.  I usually cook my (very watery heirloom) tomatoes for 2-3 hours.

When the tomatoes (and garlic) look like they've started to brown or dry out on the top and the liquid in the pan has begun to thicken slightly, turn the oven off and leave the tomatoes to slowly equilibrate. If you're worried about overcooking them you can remove the pan and let it cool on the counter, but the slower cooling process makes for extra-tasty flavor.

Step 3: Store for Later Use

When the tomatoes have cooled drop them and the remaining oil/tomato juice goo into a covered storage bowl in the fridge. I never manage to store the garlic, as it all gets eaten within seconds of leaving the oven.

Use them for proper Southern tomato pie, frittatas, BLTs, beans, stews, or anything else calling for tomatoes; eat them straight; drizzle them with a balsamic reduction; serve on toast with chevre. They even freeze well. Roasted tomatoes are basically concentrated tomatoey goodness, and can be used anywhere tomatoes are usually found.

I'll fill in more of these links as I document more of the roasted tomato uses we favor.

I'm going to try this this year. Thanks for the box of 2nds tip. I'm going to use it on my cherry tomatoes too!

Thanks for this tip ... I did not even think about roasting my tomatoes. DUH! Everyone knows Roasting makes everything taste better. Thanks for reminding me and the step by step directions. deb

These look so good! I can't wait to make them!!!

I made these and they were pretty good but next time I am going to add a little less garlic.

Thanks for the instructions! I grow many heirlooms and some were stricken by late blight :( Mostly the speckled romas. However, I do still harvest some lovely and tasty fruit. I tried this tonight with a Great White, some Speckled Romas, cute little Green Grapes (which are yellow) and a Brandywine. Because of the steam I had to suck up some juice during cooking with a baster. It was the best tablespoon of liquid I've ever had. I am also roasting yellow stuffing tomatoes, because raw they have little flavor. It's the first year I've grown them and while they're cool looking, productive and fun to grow, they aren't that tasty. It's amazing how sweet they taste after a little roasting. If you have any other tips about what to do with these besides stuffing and roasting, I'd love to read them.

Sorry to hear about the blight! That's disappointing.

I've never seen the stuffing tomatoes before. My understanding is that most of the flavor comes from the gooey innards surrounding the seeds, so that would explain their relative lack of tastiness until roasted. How do they taste when sun-dried?

Also, great blog!

I should have specified - the omnivore's solution blog isn't mine :-)

I'm gonna have to get on a garden forum and get ideas about rethinking next year's garden. Blight stays in the soil.

But anyway, they stuffing tomatoes I sliced and filled in the spaces with Green Grape (they're actually yellow) tomatoes and roasted slow at 250 degrees F. They looked cool and came out good.

This looks beautifully delicious. When you 'slow roast', what temperature do you use?

you say not to refridgerate but keep them on the counter.. would you not put them in a jar of olive oil to store long range?  how long can/do you keep them on the counter? thanks

That's for fresh tomatoes. After roasting, definitely refrigerate or freeze the tomatoes.

Do you do anything to remove the peel & seeds after roasting?

1 reply

No, I find them delicious. If you really want to remove the peel and seeds, you could push the entire contents through a strainer. But why bother when they taste good?

I gonna try tonight

Yeah Baby!!!

These have worked out excellently. After cooking, I bottle them in olive oil as 'sun dried' tomatoes. I have a small fan-assisted table-top oven, and 400F incinerated my first attempt. I now use HALF that temperature and the results are perfect. About an hour and let the toms cool off of their own accord.

Well, chief, I've got you to thank for my constant tomato purchases over the last week.
I rediscovered a farmer's market that's on my ride home, and end up going home with a backpack half full of tomatoes.
I'm probably driving my roomie nuts with the constant usage of the oven and the smell of roasting tomatoes in our apartment (and no, we don't have an apartment stove/oven~ Full sized appliances, FTW!).

I really should get some canning jars and another baking pan so I can do this more efficiently, but many thanks to you and your 'ible - I'm eating more fruits and veggies, and things cooked at home.

Now if only tomatoes didn't make me hungrier than I normally am... :)

Yes I totally agree this is the BEST thing you can do with a glut of tomatoes. Also try roasting them with a little bit of mace or cayenne pepper. To make the most delicious pasta sauce to have ever caressed your taste buds, once roasted you can rub the tomatoes through a sieve to puree them and remove the skin and seeds. Then in a frying pan, heat up some extra virgin olive oil, "melt" a generous number of salt or oil preserved anchovies, mix in the tomato pulp and then add some cream to taste. Delizioso!

THIS WOZ DELICIOUS!!!!!!!! i cooked it 4 my besties and they loved it!!

Mace? I know its loaded with capsicum, but I would think that there would be some other, not so good for you stuff in there.

This is [http://en.wikipedia.org/wiki/Mace_(spice) mace the spice], different from pepper spray. It's the yellowish-orange stuff that grows on the outside of nutmegs.
