Back in the restaurant and catering days, we would load up the oven with sheet pans full of summer tomatoes. Oven Roasted Tomato Sauce was one of my favorite things to make because juicy ripe tomatoes are at their peak of flavor! And roasting them seems to concentrate their sweetness and intensify their flavors even more.

There’s really not too much that needs to be done to a good tomato and so this is why this recipe stays “simple”.  A few cloves of garlic, a shallot, a drizzle of good olive oil, a few sprigs of oregano or basil, and a sprinkling of salt… and that is pretty much it!

You can make this recipe, one of two ways.

After roasting the tomatoes – slip off the skins and mash. They slip off very easily and only takes about 3-4 minutes.

This works well for medium and larger tomatoes.

You can either mash the tomatoes with a potato masher for a chunkier sauce, or blend for smooth. Pulsing in a food processor allows some texture to remain with some uniformity- all good options!

If you want to use smaller tomatoes, you can still slip off the skins, but since they are smaller, they will take a little more time.

Or simply blend the tomato sauce, leaving the skins on.

I do both, depending on what tomatoes I’m using.

Some people like to remove the seeds… up to you. I leave them in.

How to store Oven Roasted Tomato Sauce:

  • This recipe makes about 4 cups, enough for one or two meals, and keeps the fridge for 5-6 days.
  • You may also freeze the sauce or can the sauce for a little burst of sunshine in the winter months which I try to do every year. See the recipe notes!

An easy recipe for Oven Roasted Tomato Sauce made with fresh summer tomatoes, garlic and herbs.  Extend summer’s harvest into winter! Freeze for winter!


Units Scale
  • 3 tablespoons olive oil
  • 46 cloves garlic, rough chopped
  • 1 shallot, diced
  • 3 lbs ripe (med-large) tomatoes, cored and cut in half ( for small tomatoes, see notes)
  • —-
  • 1 tablespoons fresh oregano ( or 1 teaspoon dried, or use Italian seasoning)
  • 12 tablespoon fresh basil, torn or chopped
  • 1 1/2 teaspoons salt ( or salt to taste)
  • pepper to taste
  • 1/2 teaspoon sugar ( optional)


  1. Pre-heat ove to 400 F
  2. Drizzle a large, rimmed baking sheet with olive oil. Sprinkle with garlic and shallot.
  3. Place the sliced tomatoes cut-side down on the sheet pan and roast 30 minutes. Add the oregano and basil and roast 10 more minutes, or until skins have lifted off the tomatoes.
  4. Let cool, pull off the skins, then pour all the tomatoes and their roasting juices into a bowl. Mash with a fork or potato masher.  Season with salt and pepper. Sometimes, to bring the flavor around I’ll add a little sugar. This depends on your palate and the tomatoes you are using ( some are sweeter than others). Start with ½ a teaspoon. Taste, adjust.
  5. To use right away, reheat in a pan or pot. Or refrigerate for  up to 5 days, or freeze.
  6. If freezing in a mason jar, make sure jar and lid are clean and sterile. Let sauce come to room temperature. Fill jars leaving 2 inches headroom at the top of the jar, to prevent jar from breaking-  because sauce will expand as it freezes.
  7. Thaw in the fridge for 24-48 hours.


If roasting small tomatoes, feel free roast whole and blend the sauce with the skins on. They may not need as long in the oven, check after 20 minutes.

If canning the tomato sauce, follow these instructions:

  1. Prepare boiling water canner. Heat a quart-jar in gently simmering water until ready to use, do not boil. Wash lid in warm soapy water and set aside with bands.
  2. Add 2 tablespoons lemon juice to the hot, 4-cup, quart jar, (or 1 tablespoon to a pint jar)  ladle hot tomato sauce into a hot jar leaving a ½ inch headspace. Remove air bubbles. Wipe the jar rim clean and seal lid to fingertip tight.
  3. Place jar in boiling water canner and process for 40 minutes. Turn off heat, let jars sit 5 minutes in the water. Remove jars and cool 12-24 hours. Check lids for seal, they should not flex when center is pressed.

  1. Have a bounty of heirlooms that I wasn’t sure how we were going to eat them all. Just cooked this on a whim and it’s SO GOOD. I know what I’m doing with my tomatoes every year!

  2. Really delicious and easy sauce recipe. I had early girl tomato’s and sun sugar cherry tomatoes so no added sugar needed. Wow, really tasty sauce.

  3. OK – I need advice. First of all, this sauce is delicious. The ripe tomatoes from my garden came in the kitchen and went straight into the oven. Also used our garden shallots, basil and oregano. Fantastic! Now my question: In what recipes would you use this so that the flavor shines through? Nearly all of my recipes that call for tomato sauce only use 8-16 ounces and the flavor of the sauce, no matter how good, becomes subservient to the other ingredients. It’s delicious, but also probably can’t stand on its own such as over pasta. Other ideas? Maybe I’ll just drink it. 🙂

    1. Not sure why my rating came through as 4 stars. I fully intended to give this the 5 stars it deserves!

    2. Haha! I usually just serve it over pasta, or with meat balls, and sometimes I’ll blend it into soup.:)

      1. Serving over meat balls is a great idea. Using super fresh tomatoes made it a little more watery than probably intended. I’m thinking that I can possibly boil it down a bit to concentrate the flavors more.

        1. Yes, it will cook down some as you simmer the browned meatballs in it, then sprinkle with pecorino- super yummy. 😉

    3. You can make it with eggplant lasagna, chicken parmigiana, if thick enough use it as pizza sauce, and try it and have it with mozzarella sticks.

  4. I never comment or give reviews, but I have to tell you, I have probably made this at least five times and will never stop. That says alot because I’m always trying new recipes. This is ambrosia with farmers market tomatoes. We absolutely adore it. I could sit and eat it with a spoon. Thank you so much


  5. I did and it was delicious! Thanks for sharing! I added a little heat and sweet, roasted at 425. Served over pasta with a little Parmesan. Enjoyed every bite.

  6. This is fabulous!! I pulled the skins off, put them in a cuisinart mini-chop and pureed them. They became a wonderfully rich paste which I added back to the sauce. Thanks so much for the recipe!

  7. Just made this and will NEVER do it any other way. OMG it is so good. We might can it if my husband will quit eating it straight out of the pot!

  8. I picked a few dozen tomatoes from my garden last week with the intention of making 2 recipes for sauce, this and another. Well, the other never happened, this recipe is exactly what I was looking for – easy and delicious! I used a mix of red, black and orange heirlooms and changed up the herbs a bit but overall, didn’t deviate from the directions. I’ve made this three times now, it’s my new favorite for oven roasted tomato sauce.

  9. This was a great recipe for my, first time grown, midnight roma heirloom tomatoes. I used fresh garlic since the cooking time is shorter for Romas. I emptied the entire concoction into a medium sized pot. Add spices and some red wine and a bit of water. Cooked it on low low heat for an hour and a half. It produced a luscious sauce. I did this with only 15 tomatoes which yielded about 3 cups of sauce. I will never ever blanch tomatoes again. Lovely.

  10. A geat tomato sauce–we buy a bushel of san marizano tomatoes just for this. I use a sliced onion (instead of the diced shallot) and sometimes also add a sliced carrot (for sweetness if the tomatoes need it) to the cookie sheet. My go to herb is thyme (few sprigs of fresh) and once cooked, I freeze the sauce in flat takeout containers to make bricks (sometimes I blend it smooth, sometimes I leave it chunky). I like to then pop out my tomato bricks and vaccum seal them for longer term storage in the freezer. What a treat come Jan-Feb to pull out summer sauce with fresh gnocci!

  11. I used this recipe to can 50 lbs of tomatoes yesterday and it is so good. When I woke up this morning I noticed that the olive oil had separated and risen to the top of the jars and now I am very nervous about botulism. I have never canned a recipe that required oil before. Should I freeze the sauce now?

  12. I just made this Sauce and it’s wonderful! I did not add sugar but was quite generous with the olive oil.
    I let the tomatoes cool, then processed in my blender.
    To thicken the sauce I added a can of tomato paste.
    Thank you Sylvia

  13. Simple and delicious. I used the speckled roman tomatoes and blended with the skins after 20 minutes in the oven. Came out perfect, even on the thick side.

  14. Simple but results in such depth of flavor! Made this with a batch of sauce tomatoes from my garden and was blown away. I served it with Smitten Kitchen’s spaghetti pie and that was quite a combo. It was almost better the next day! I look forward to making this again.

  15. Love this easy but flavor-packed sauce. It paired well with so many dishes, including over spaghetti squash.

    I made this as written a couple of times last summer with garden tomatoes gifted from neighbors. Jarred and froze for the winter.

    Also followed the same recipe except put everything on the grill for a fire roasted version. Equally as good.

    Sylvia, every one of the recipes written by you that I’ve tried has been great (and I’ve made several!) Can’t think of one that I needed to tweak (except for salt—going a bit lighter for personal tastes and health concerns). It’s so great to be able to trust a recipe as written and not have to scroll through a hundred comments to find out issues!

  16. I got a ton of tomatoes from my Dad and wanted to make sauce that was not going to take me all day and this recipe was PERFECT. My sauce came out awesome and I can’t want to eat it. I did add 2 hot peppers from my garden, which kicked up the heat.

  17. Love this! I used 1/2 cherry tomatoes from my garden and 1/2 Roma tomatoes from the grocery store. I also added about 6 small sweet peppers when roasting because I had extra room on my baking tray. Once done and cooled a bit I dumped it all into a medium saucepan and used my immersion blender a bit to roughly sauce them. Delicious over stuffed zucchini with a little parmesan cheese sprinkled over top!
    No sugar needed! These were super sweet thanks to the peppers!

  18. This is delicious!! I added some red wine, some beef bouillon,parmesan and ground beef and made a meat sauce. So good!!!

  19. Has anyone tried to use/eat them without mashing them on toast or biscuit? I have been looking for a receipe its half chopped cherry tomatoes with garlic and basil in Olive oil…

    1. I think it would work as long as you strain out any excess liquid. The pasta really soaks it up and takes on the wonderful flavors, but toast or a biscuit might get soggy. You could also just cook the sauce down longer on the stove so that it’s a thicker consistency. Maybe “winter bruschetta”?

  20. Excellent recipe, so easy and very tasty. This will definitely be my go to recipe for Marinara sause in future.
