An easy recipe for Oven Roasted Tomato Sauce highlighting juicy, ripe summer tomatoes! A fun, simple way to extend summer’s harvest! Freeze or can for winter!
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 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.
Serve it over your favorite pasta, or if going low-carb, try the oven-roasted tomato sauce over zucchini noodles or spaghetti squash… so delicious!
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!

Description
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!
Ingredients
- 3 tablespoons olive oil
- 4– 6 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)
- 1–2 tablespoon fresh basil, torn or chopped
- 1 ½ teaspoons salt ( or salt to taste)
- pepper to taste
- ½ teaspoon sugar ( optional)
Instructions
- Pre-heat ove to 400 F
- Drizzle a large, rimmed baking sheet with olive oil. Sprinkle with garlic and shallot.
- 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.
- 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.
- To use right away, reheat in a pan or pot. Or refrigerate for up to 5 days, or freeze.
- 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.
- Thaw in the fridge for 24-48 hours.
Notes
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:
- 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.
- 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.
- 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.

So easy and simply the most delicious tomato sauce recipe I’ve ever made. Thank you.

Just made this with a bunch of leftover tomatoes from the garden and added purple basil, rosemary and oregano. Wow! The flavor is amazing. Added it to some italian sausage I got from a local butcher and am making some spaghetti tonight. Thank you!
★★★★★
The taste is delicious. How could I thicken it, though? I could leave out the roasting juices, but they are very flavorful! Thanks, Sylvia!
You could cook it down on the stove letting the juices condense and concentrate.
A neighbor gave me several pounds of Roma tomatoes so I decided to try this recipe. It was my first time making homemade sauce and it came out better than I expected. I didn’t use all of the juices from the pan and I left the sauce on the chunky side. It was perfect over ravioli.

I love this recipe and will now make my 3rd large batch today from my garden tomatoes. However, I used a lot more onion and premixed it in a bowl with the salt, pepper, sugar and oregano and garlic. I roasted it longer (40-45 min) because I had 3 large trays and lots of tomatoes. I put the tomatoes with seeds and skins right into my food processor along with everything on the baking sheet and the fresh basil. I also added a can of tomato paste and 3 cubes of Dorat’s frozen pureed onion plus garlic powder and more salt, pepper, sugar, oregano, etc. It is hands down the best tomato sauce I’ve ever made. I’ve given some away, eaten some plain with parmesan and have divided the rest in ziploc freezer bags. THANK YOU!!!!!
★★★★★
Great to hear Shirley- glad it worked for you!
Thank you so much for this recipe! The great thing about this is you can use your ugly tomatoes. I have finished my garden tomatoes and now buy from the farmers market. My family loves this sauce on spaghetti. I am now making my 5th batch. I do add more herbs from the garden and sometimes roast red pepper with them. I prefer to pulse in the blender. I do not use sugar
★★★★★
Haha! Love it! Thanks for sharing.
Delicious. I did remove some of the juice before adding any spices, and cooked it a bit longer (45 minutes) which made a wonderfully thick sauce. My first try at oven vs. stovetop and I’m hooked!
Could you freeze this??
★★★★★
Totally!
This is so easy and so delicious. I will definitely make it again with the tomatoes from my garden. I used the food processor to whirl it up but still leave a little texture.
★★★★★
I made this recipe for the first time and it is amazing tasting and smells but I have a very runny sauce. Any recommendations for thickening it? I did try cooking it on the stove on low for a few hours but it is still more of a soup consistency.
★★★★
This is a looser sauce. 🙂
Please be clear about what size jars you use for 2 T lemon juice.
2 tablespoon per 4-cup, quart-jar. I adusted recipe and please see the new link in recipe notes for canning- it is helpful.
Loved the look of this recipe so I went ahead and made it…..outstanding flavor ! I followed it exactly and did multiple batches. Tried the potato masher unsuccessfully once It was roasted, so needed a few twists of my immersion blender for a beautiful consistency.
★★★★★
Perfect, thanks Debbie!
Hello: Is there a way to blend the sauce so it’s smooth without being frothy? Thank you so much!
Frothy as in air bubbles? The froth should settle down if you let it sit a bit or tap the blender so bubbles rise to the top and pop.
what size jars ? and is this an approved recipe of the NCHFP ?
Quart jars.
I’m always trying to find the easier, best recipes. I have been fortunate to find a few. This is definitely one of them. So easy, so quick…I can’t stop dipping some great rustic bread and butter in to this stuff! House smells great. Hope there’s enough left for dinner!
★★★★★
Haha! Love it Mike- thanks!
Thank you for the great recipe! We love this sauce, and have made four batches with our garden tomatoes. Such an easy one to make with such wonderful flavor.
★★★★★
Absolutely love this sauce! I’m on my third batch…..freezing some and eating some each time. I wasn’t sure what to do with all the great tomatoes I grew ( shared with my coworkers before working at home/covid) and you provided an easy delicious solution. Thank you!
★★★★★
Glad you are enjoying this Chris!
We’ve made this recipe for tomato sauce three times now. It is excellent, and so very flavorful. We used very ripe heirloom tomatoes and the sweetness and depth of flavor was incredible. I think I can safely say, best tomato sauce ever. Thank you, Sylvia.
★★★★★
The tomatoes are in the oven now, the smell is divine! 🙂
Can you tell me the ratio of lemon juice for canning, please. Is it 2 tablespoons per pint, half pint, Quart? Would Citric acid and less of an effect on taste?
Thanks
I’m not a canning expert… so I would be totally guessing here. Sorry. 😐
1 tablespoon bottled lemon juice per pint, or 1/4 tsp citric acid.
