This Heirloom Tomato Jam is perfect in the summer when you have an abundance of tomatoes that you need to use up. It’s sweet but not in a dessert way and great on toast with eggs for breakfast.
What is tomato jam?
Just like fruit jams, tomato jam is made up of tomato, sugar, and aromatics. It’s not enough sugar to make it something you’d eat for dessert but it’s just enough to balance out the acidity in the tomatoes. The aromatics I’m adding are just adding to the savory factor to help balance it all out.
What does tomato jam taste like?
Like a super intense flavorful tomato. It’s sort of the idea of concentrated tomato paste but more rounded and in a jammier consistency.
What do you eat tomato jam with?
All kinds of things! Think of it as a much fancier ketchup, you can eat it with:
- eggs
- potatoes
- use it on a sandwich
- mix it into cooked rice
- use it to top grilled fish
What kind of tomatoes do you make tomato jam with?
I used heirloom tomatoes for this jam, but you can really use whatever tomatoes you want to use or can buy at a good deal. I’ve also made it with sungold tomatoes and they worked really well.
How do you make tomato jam?
- Prepare the tomatoes. Hull and roughly dice the tomato, making sure to cut out any soft spots or blemishes.
- Cook the jam. Add everything to the pot and cook for an hour or so, making sure you stir during this time so the jam doesn’t stick.
- Jar it up. Cool the jam completely, and transfer to a jar to store in the fridge for up to 2 weeks.
Tips and Tricks:
- You can make these with whatever tomatoes you need to use up! the flavor and cook time will vary depending on the tomato variety, just keep an eye on the jam while it cooks.
- Switch up the aromatics! I used thyme but you could also add garlic or use oregano or basil.

Tomato Jam Recipe
Ingredients
- 3 pounds red heirloom tomatoes
- 2 tablespoons light brown sugar
- Pinch of salt
- 2 tablespoons red wine vinegar
- 1 teaspoon dried thyme leaves
Instructions
- Hull and cut the tomatoes into a rough dice. If you're using heirloom tomatoes, be sure to cut off any tough, brown spots that might be on their skin. Transfer the chopped tomatoes to a non-reactive medium pot, along with the brown sugar, salt and red wine vinegar. Place the uncovered pot over medium heat and bring the mixture to a simmer; cook for 30 minutes. At the 30 minute-mark add the dried thyme and mix. Cook for an additional 25 to 30 more minutes and until the mixture is thick. If you're using more or less tomatoes, the cook time will definitely vary.
- Allow to cool to room temperature. Transfer to a jar and store in the refrigerator. Tomato jam will be good for two weeks without canning.

I was so enticed by this post, so I had to pick up a bag of Heirloom tomatoes at the Farmers Market on Sat and made this jam on Monday. I have never had tomato jam before and I am now totally hooked. I am craving some right now as I type about it!!!!Thank you so much for providing this easy and wonderful recipe. Love your blog 🙂
Oh! This makes me so happy. I’m so glad you loved it. I’ve been using my can of tomato jam to put on toast all week long. I love it!
I am glad that I have found someone that also hates the word “moist”. It literally makes me cringe!!
Funny, I just made tomato jam last night! The recipe I used called for 2 pounds tomatoes and 1 cup honey. I think it’s too sweet. Yours looks fantastic!
Oooof. I made this recipe a few times with more brown sugar and found it WAY too sweet. It’s sensitive to sugar. 🙂
Yay for jam! I recently made jam (accidentally bought 200lbs of fruit..) but never thought to make tomato jam! It looks so, so good.
My dog would die of happiness if we took her somewhere to herd sheep, she already tries to herd any other dogs or cats whenever she can. I remember a trainer telling us not to take her out to a farm with sheep because she’d love it so much that she’d never be happy again at home with us. A little dramatic, but she’s sort of a dramatic dog.
Just found your blog and I’m loving reading through all the posts 🙂
You accidentally bought 200lbs of fruit! That’s crazy…and AMAZING. So glad you’re here!
I can’t wait to see the photos!
This is awesome!!!! I have so many tomatos and not enough recipes!
Adrianna, I LOVE tomato jam! And this is the perfect time of year to buy those “reject” tomatoes and cook em up. I need to get to work;)
Good luck with your little sheep herder… adorable!

one the best things at the fruit market has to be left over discount veggies in Australia. They make the best sauces and jams in town, if fact it is recommened to use very ripe fruit/veg in preserves as it is sweeter and easier to break down.
I am looking forward to tomato season in Australia, so I can try this on a sour dough panni!
Heirloom tomato jam… you’ve got me sold! And I know how good it must taste because I actually whipped up a batch of slow roasted tomatoes and turned them into a jam. It was delicious and the perfect spread for a sandwich or grilled cheese… I can’t wait to make your recipe! But, I have to hurry up before all the good heirloom tomatoes are gone after Summer 🙂 Here’s my link to mine…

I CANNOT WAIT to see your little corgie herding sheep. Also, this jam looks amazing. All killer, no filler.
OMG! This jam is the epitome of Summer. Love.
I always try to go a little late at the farmers market to get cheaper tomatoes so I can make my own tomato sauce or chutney but have never made jam and I have the feeling I’m so going to love it! Now if only I find heirloom tomatoes for $1 a pound like you did
I like to go a little later too! It’s a good move. 🙂
I’m so excited to have just found your blog! The recipes look amazing and I can’t wait to try some!

Hiiiii! Welcome, welcome! Glad you’re here.
Gurl I’m all over this tomato jam on that gorgeous bread!
Gurrrrl. I like you, so glad.
I’ve made tomato compote very, very similar to this and it makes an excellent pizza sauce. Add a little garlic, some ground pepper, and you’re all set.
This on pizza would be dope. Especially like bagel pizzas.
