Oven Roasted Tomatoes

There are a lot of things I love to do with fresh tomatoes, but one thing trumps them all: Oven Roasted Tomatoes. It’s a simple process, and my favorite thing to make with an abundance of tomatoes from the garden.  Tomatoes are simply cut, tossed with olive oil, salt, pepper, and garlic, and slow roasted in the oven.  The slow roasting process draws out moisture and intensifies flavor and sweetness.  It results in rich, thick, flavorful tomatoes that can even come out closer to sun dried if you leave them in a bit longer.  They can be blitzed up in a food processor and turned into a sauce or soup, tossed with pasta, used as a spread, added to soups and stews, used on sandwiches, in casseroles, or simply snacked on plain.  I like to keep them stocked in my freezer to use throughout the year.

Ingredients Needed

  • Tomatoes – You can use this method on literally any type of tomato.  The important thing to remember is that they should be about equal in size once in the oven.  So if you have some giant tomatoes, you might want to cut them into eighths, and small tomatoes might be on the same pan simply cut in half, while if I’m doing cherry tomatoes, I generally leave those whole and put them on their own pan in case they need to be removed from the oven early.  Keep in mind that some varieties of small cherry tomatoes have a large amount of seeds though, which can turn out a little bitter.
  • Olive Oil – extra virgin olive oil works great for roasting.
  • Garlic – you’ll want to use fresh garlic, not garlic powder.
  • Salt and Pepper – this brings out the flavor of the tomatoes. I prefer kosher salt and fresh cracked pepper.

How to Make Oven Roasted Tomatoes

  1. Cut your tomatoes and remove the pulp. I like to cut most average-sized tomatoes in quarters. As you cut just use clean hands to gently push out pulp (into the sink or garbage) and set tomatoes down on a parchment or foil-lined baking sheet. You don’t have to remove every last drop of pulp, but a quick squeeze will help remove extra moisture that can slow down the roasting process.
  2. Toss tomatoes in olive oil and season. There are no measurements listed in this recipe because you can make as little or as few as you like! You’ll just liberally drizzle your tomatoes with extra virgin olive oil so they are all well coated. They should be glistening and there should be some oil on your baking sheet.  Sprinkle with salt and pepper, and I like to add a good amount of minced garlic as well.
  3. Toss tomatoes and roast. Toss it all together so everything is well coated and evenly space out tomatoes in a single later. I like to put skin-side down and if I see any obvious chunks of garlic on the pan, I try to pick them up and put them on top of a tomato so they don’t burn.

Frequently Asked Questions

Can I make these in an air fryer?

The cooking process here is low and slow. Air fryers cook too hot and have a fan to blow away the moisture. You can get really delicious tomatoes in the air fryer, but it won’t be quite the same as a long oven roast.

Can I mix tomato varieties?

You can! Just be aware that different tomatoes have different consistencies and moisture contents so they might roast differently. If you have different varieties on the same pan, just know that some might get done quicker than others.

Can I can these?

No, this recipe is not developed nor tested for canning. Freezer storage is the best solution for long-term preservation.

Equipment

Ingredients

  • tomatoes any variety
  • olive oil extra virgin
  • kosher salt
  • pepper, freshly cracked
  • garlic cloves 4-6 per pan, minced or pressed

Instructions

  • NOTE: This recipe doesn't have measurements because it varies depending on the variety of tomato you're using. So we're eyeballing! Don't overthink it- it's hard to mess these up!
    Preheat oven to 325℉. Line rimmed cookie sheets with parchment or foil.
  • Quarter tomatoes. If you have large cores, feel free to remove those, but for small soft cores, I just cut right through an roast them up. 
    You want all of your pieces similar in size.  If you're using small tomatoes, you can sometime just cut them in half. Anything larger, quarter them.
  • As you cut tomatoes, use clean hands to gently remove excess pulp. You can then place them directly on your baking sheet, or – I like to keep a big strainer over my sink and place them there to drip off excess moisture while I'm prepping.
  • When done prepping tomatoes, place them on a baking sheet and drizzle generously with olive oil, enough to coat everything well. Sprinkle with salt and pepper. Sprinkle 4-5 (or more!) finely minced garlic cloves on top. Toss together so everything is coated.
  • Arrange tomatoes in a single layer, skin-side down, on your sheet.  Make sure most of the garlic is on top of the tomatoes and not on the baking sheet. Your tomatoes should be in a single layer and not too crowded. If they are not, pull out another pan and use 2 so you can spread them out.
    Note: If tomatoes are too crowded, they'll boil instead of roast.
  • Place pan in oven and cook for about 2.5 hours. Important note about baking time: all ovens are different and tomatoes will vary on baking time due to a variety of factors (size, amount of pulp removed, desired level of doneness, and so on).  I suggest setting your timer for 1.5 hours and taking a peek through the oven window about every 30 minutes from then on, until they are finished.  Small tomatoes will be done early, larger pieces take closer to 2.5- 3 hours. I personally like my tomatoes to get a little chewy and browned so I leave them in longer. It's not uncommon for the liquid on the pan to start to turn black- this is normal, but keep an eye on your tomatoes to make sure they aren't burning on the bottom.
    Tips:
    -If you can see the tomatoes on the perimeter of your pan are getting done more quickly and starting to char, feel free to toss and rearrange, keeping tomatoes skin side down before returning to oven.
    -If cooking multiple pans at a time, rotate through baking for even cooking.

Notes

  • Remember that liquid will be evaporating and flavors intensifying, so I recommend going a little lighter on the salt than you’re inclined.
  • If using cherry or grape tomatoes, simply cut in half and squeeze out juice.  This can be tedious, but I’ve found leaving whole often releases to much moisture, and not squeezing out the pulp sometimes ends up causing a bitter flavor.  But feel free to experiment!

Questions & Reviews

  1. I made your yummy roasted tomatoes and wonder if you freeze them after vacuum sealing? Or, if I add an oxygen packet, then vacuum seal, are they shelf stable?

  2. You forgot to mention that my whole house would smell AMAZING for hours and I would have overwhelming cravings for all things Italian!

  3. 5 stars
    I had 75 lbs of Romas I had to do something with.
    Cut them in half long ways, EVOO, little salt, and roasted them at 425 (convection roasting) for about 45 minutes. I also added big wedges of onion to the pan and entire head of garlic to roast along with the tomatoes and onion. My house smelled like Italian heaven! I squeezed the garlic out and put some in every bag of tomatoes I froze. I have enough to last through the winter.

  4. 5 stars
    I make these tomatoes every year. The house does smell amazing. They barely make it from the oven to the table.. healthy candy!

  5. I have made tomatos lije this for years i usually use plum or cherry tomatos
    I add them to cream cheese when they are still warm and then refridgerate it and add to your morning bagels!!!!!
    (I also add raw suger to the tops to help with carmilization)

  6. Does any one know if previously frozen tomatoes from the garden can be roasted? While I was out of town last week my sweetheart boyfriend tried to help me out by freezing them when he was inundated! Thanks

    1. I actually freeze whole tomatoes all the time! I’ve never roasted them, but the work great in things like salsa and tomato sauce. I bet they would actually roast okay, too. I would thaw them out and drain off as much of the liquid as you can first.

  7. 5 stars
    This is without a doubt the best recipe! I look forward to my tomatoes ripening every year so I can make these. The house smells heavenly as they roast. None of them ever make it very far. Oven. Cool (sort of) and consume! I have given many friends this recipe, along with tomatoes. Excellent! This year I just couldn’t wait for the Roma’s so I used the cherry tomatoes. Very good!!
