Step 1: Preparing and Roasting the Tomatoes

Preparing and Roasting the Tomatoes

Preheat the oven to 250° degrees Fahrenheit.

In a small bowl, whisk together the crushed garlic, olive oil, grey salt, Herbes de Provence and pepper.

Cut the tomatoes in half and arrange them on a parchment-lined baking tray, cut side up.

Spoon a bit of the mixture over each tomato, stirring as you go because the garlic tends to sink to the bottom of the bowl.

Bake the tomatoes for 4 to 6 hours. The longer you bake them, the more concentrated their flavor will be. Cool the tomatoes before transferring them to a platter. They can be served right away or will keep in the refrigerator for a few weeks.

Serve these simple but flavorful tomatoes as a garnish for a brunch or as a side with roast chicken or a grilled steak.

  • 2 garlic cloves
  • 6 tbsp extra-virgin olive oil
  • 1/2 tsp quality sea salt
  • 2 tsp herbes de provençe
  • 1/2 tsp freshly ground black pepper
  • 18 medium Roma or 24 Campari tomatoes

Notes

When tomatoes are in season and are juicy and full of sweet flavor, you can make a big batch. The great thing about these tomatoes is that they will keep in the refrigerator for a few weeks.

Very Tasty Tomatoes!

I just made this recipe. I have to say it was very easy to follow. The end result... DELICIOUS.
I keep them in the oven for 4.5 hrs, they came out very moist and tender.

Authentic

It had a authentic italian taste to it, I much prefer sun-dried yet and either are perfect.

difference to sun dried

How different is this to sun dried tomatoes?

Soft and Still Juicy

These tomatoes are different than sun-dried tomatoes as they are not dried as long, leaving them a bit "meaty" and juicy inside. You could cook these tomatoes longer and this will dry them out and concentrate their flavor, making them more like sun-dried tomatoes.

It all depends what you are using them for I guess.The great thing about this particular method is the tomatoes can be served as is. Unlike sun-dried tomatoes, these tomatoes are great served as a side with grilled chicken, steak, pork...and like sun-dried tomatoes they are even good tossed in pasta.

Very Popular!

I've made these tomatoes twice now and each time they disappear very quickly. I've also passed the recipe on to a friend who was very pleased with the results. I'm making them again today for Christmas dinner.

Thanks for the great (and very easy) recipe.

Awesome!

I made these tomatoes and the flavor was intense and delicious!
I served them with a nice pan seared Arctic Char and my guests went nuts over them!
I stored them as suggested and after a day or two I sliced them up and tossed them with some capellini for an easy and yummy dinner during the week.

Thanks for a super recipe and easy to prepare as the previous poster mentioned.

Inspiring

It is amazing that a simple tomato can turn out to be an extra ordinary treat. I haven't decided what to do with them yet except to eat them for now.

Addicting

I've just put two more trays of these delicious tomatoes in the oven. They are amazingly easy to make and deliver an incredible flavor. My husband insists on having them at least once a month and swears they are addicting. The only difficulty is having to wait the 4.5 to 5 hours for them to slow roast. Thank you for all the memorable recipes and meals!

Marinade - Oven Roasted Tomato

I use a similar marinade for lamb and veal roast. Increase the volume; add 1/3 to 1/2 cup dry white wine; fresh squeezed lemon juice (1 or 3 lemons depending on quanitity) and 2 tablespoons good Dijon mustard.
For a zippy switch use lime juice instead of lemon.

Place marinade and roast in a plastic bag. Marinade for at least 3 hours in the refrigerator or overnight in the refrigerator.

The meat roasting will most certainly bring people to the table before it's done.

I add the bag juices to the roasting pan or clay baker and let them cook with the roast. Use the cooked juices and suc to make a light or thicker sauce to drizzle over roasted potatoes and the slices of roast. Of course handle the juices with care to ensure health safety.

Re: Marinade - Oven Roasted Tomato

Sounds delicious Tony - will have to give it a try. Thanks for sharing your tips and tricks. Cheers!

Great Foccacia Topping

We used large Roma tomatoes and baked them for only 4 hours. Because of their size they were still a bit moist. Larger tomatoes need at least 5 to 6 hours. However, they were still delicious on our homemade Foccacia bread.

Brunch

I bet these would make a great light brunch with some fresh mozzarella.
I will be making these soon. Thanks Dawn.

roasted tomatoes

I sliced my tomatoes before I reviewed the recipe, but it was not a total failure. I had sliced each roma tomato into ~3/8 inch slices (about 5 slices per tomato). I seasoned with oil, herbs and salt and baked them for an hour at 275 - 300. They were actually pretty good and ended up great in sandwiches and garnishing the top of a chile corn chowder. I cut the tomatoes in half and formed a nice scalloped circle in the bowl and put fresh chopped chives in the center. My question is this: With the slender slices of tomatoes roasted in oil, dare I say I could call my blunder a 'tomato confit'? Would that be correct? 2nd question: do these freeze well? As soon as tomato prices drop, I am making a ton of these (both sizes!!) Thanks!!

Re: Roasted Tomatoes and Tomato Confit

Regarding your first question about whether or not you could call what you made tomato confit or not, to this I would say, that if you like you can say they are tomato confit; however technically the true definition of "confit" is a meat cooked and then stored in it's own fat. Unfortunately, the word confit is quite misused just to make things sound fancier, even Thomas Keller has a recipe for tomato confit in his Bouchon cookbook. I have to admit that tomato confit does sound a bit sexier than tomatoes cooked in olive oil but really that is all they are (sorry tomatoes).

For a bit of a funny read about this you may want to read this article I found a while back called "What does "Confit" mean?"

As for freezing these tomatoes, I am not sure as I have not done it myself. I simply cover them with olive oil and store them in the refrigerator (they last for several weeks like that). Due to tomatoes high moisture, I am not sure that they will freeze that well but you could always take a small bit of your last batch and try to freezing them to see if you are happy with the results. Hope this helps. Cheers!

roasted tomatoes and tomato confit

Thanks Rouxbe for staying true!! I have seen the term confit used on many foods and I thought it was a meat preparation but who was I to argue? I love the article; it cracked me up...
"Chefs ‘confit’ everything; tomatoes, aubergines, onions, fruits, coffee percolator, cuddly toy, kitchen sink, you name it and it’s on a menu at a restaurant near you."
Thanks again for setting the record and the term'confit' straight! Keep up the great work!!

Reheating tomatoes

Delicious! Worked like a charm. If I make these ahead of time, what do you think is that best way to reheat them?

RE: Reheating Tomatoes

Place them into a baking dish, cover and reheat them in a warm oven. You could even use the microwave. Cheers!

Grape Tomatoes

Dawn/Kimberley:

Any idea what to do with 10 pints of grape tomatoes. Just had a large gathering and have a ton left over. Any ideas of something I can do with them that would store well?

Thanks,

Kimberley S

RE: Grape Tomatoes

They will be delicious roasted. You can put them in pasta or risotto, on pizza, in sandwiches, frittatas or salads...on a steak, or serve them as a side with chicken...or make a roasted cream of tomato soup out of them. The list is endless. They will store for a week or so in the refrigerator or longer if you cover them with oil (see attached drill down). Cheers!

Tomatoes/Oven Calibration

Hi, I put these in oven for 5 hours and they ended up looking like the 2 hour photo in the video when I checked. (In the end I left them in oven from 10pm to 6am!) I also had delays with the braising recipes.

I am concerned that my oven needed re-calibrating- do you have a recommendation for an oven thermometer? For my miniature underused NYC oven?? Or another way to test that the temperatures are accurate?

Re: Testing the Temperature of Your Oven

Indeed, it sounds like the temperature of your oven might be off. One of the best and simplest ways to test the accuracy of your oven is by using an oven thermometer. You might be surprised by how much your oven can be off.

This is the oven thermometer that we use. It's not too big and not too expensive but it does the job. Cheers!

Temp

ive made these a few times now and love em! However the other day I put in a batch at 160 c (by mistake) ! When I checked, luckily, after 2 hours some of them (the smaller ones) had started going very dark- at which point I realized the temp! However i thought they were just as good and think from now on I may go with the higher temp to save time!

Re: Temperature for Oven Dried Tomatoes

Yes, I often roast tomatoes as various temperatures. It really just depends on how concentrated I want the flavors, as well as, how much color and moisture I want them to have in the end. And of course, how much time I have. Cheers!
