Have you ever wished that you could bottle up a moment and save it, maybe to divvy out a few drops at a time, to experience the sheer pleasure of a certain season or period in your life over and over again?

Trust me when I say that no matter how busy you are right now, you need to drop everything and pause for a minute to let me tell you about this recipe.

This tomato jam is the essence of summer.

It’s outdoor picnics enjoyed while the sun sets in the distance. It’s the bottled version of long summer nights, and roads lined with cornfields.

It’s spoonfuls of Saturday morning farmers markets and months of vacation from school, when the weeks stretch out before you, never rising until late morning when the temperature is just beginning to creep upwards as an indicator of the steamy afternoon to come.

It’s a reminder of visits to the pool and the lake and your friends’ houses, when everything smells like cut grass and hot asphalt, with just a hint of the sweet aroma of your neighbor’s rows upon rows of flowers wafting by on a warm breeze.

And look, you don’t have to believe me – yet. But to say that this tomato jam will change your life is no exaggeration.

It’s a unique variation to your typical summery varieties of fruit spreads, like peach or strawberry basil.

But when you try it at home and see for yourself what happens to a pound and a half of freshly picked, blanched, and peeled sweet tomatoes (ones that you plucked from your own garden, or picked up from a roadside stand) you will start to believe in the magic of this recipe.

When they’re combined with onions, basil, honey, and spices, and left to simmer low and slow, releasing their juices and breaking down and turning into something else entirely, you will know that alchemy is real, because you will have created a substance that is roughly the equivalent of tomato gold.

Pure gold.

Homemade Tomato Jam

  • Author: Shanna Mallon
  • Total Time: 1 hour 35 minutes
  • Yield: 2 cups 1x


Keep the flavor of summer alive with homemade sweet and savory tomato jam. This condiment will become a favorite at every meal.




  1. Bring a large pot of water to boil, and blanch the tomatoes a few at a time, until the peels loosen (about 1 minute). Transfer immediately to an ice bath to cool, and peel carefully. Remove the cores and dice.
  2. Place the diced tomatoes in a large saucepan with the rest of the ingredients, and stir to combine. Bring the mixture to a simmer over medium-high heat, then reduce the temperature to medium, keeping a slow simmer going.
  3. Cook for 1-2 hours, stirring occasionally and adjusting the heat as needed, until the mixture is thick and syrupy. Remove from the heat and transfer to another container to cool.
  4. Serve at room temperature, or store in an airtight container and refrigerate for up to three days.

Cooking By the Numbers…

Step 1 – Prep and Measure Ingredients

Wash all of the produce well, and measure out your honey and spices.

Juice the lemon, and remove any seeds if necessary.

Small round and square glass bowls of lemon juice, chopped basil, salt, cayenne pepper, ground black pepper, and olive oil, on a dark and light brown striped wood surface.

Get out a sturdy cutting board and your favorite chef’s knife. Dice the onion and set it aside. Fighting to stop those tears? Check out our tips.

Remove the stems from the basil and discard (or save them for use in a homemade vegetable stock). Chop the leaves and set them aside.

Step 2 – Blanch and Peel Tomatoes

Bring a large pot of water to a boil over high heat. Cut a shallow X in the peel of the blossom end of each tomato (opposite the stem). Fill a large bowl with ice and water to make an ice bath, and set it aside.

Five red tomatoes with shallow X-shaped cuts scored into the bottom of each, on a white plastic cutting board.

Add the tomatoes in batches to the boiling water. Once the skin begins to separate, wrinkling and splitting in some places after about 45 seconds to 1 minute, remove from the water using a slotted spoon and transfer to the ice bath.

Allow the water to return to a boil between batches if necessary, and repeat the process until all of the tomatoes have been blanched.

When they are cooled enough to handle, carefully peel, core, and dice the tomatoes, and place them in a large saucepan or small stockpot.

Step 3 – Cook

To make the jam, add the lemon juice, onion, basil, honey, salt, black pepper, and cayenne to the pot. Stir to combine.

Chopped onion, basil, and tomatoes in a stainless steel bowl, on a striped wood surface.

Bring the mixture to a simmer over medium-high heat, then reduce to medium. Keep the mixture simmering until it is thick and syrupy, stirring occasionally. This will take about 1-2 hours (it took 1 1/2 hours for me).

Do not allow the mixture to boil or stick to the bottom of the pan while it is cooking. You don’t want your jam to burn.

Step 4 – Cool and Store

Remove the saucepan from the heat and let the jam come to room temperature before storing in an airtight container. It will keep in the refrigerator for up to three days.

Why Does Homemade Taste So Much Better?

Sometimes, when I look at certain recipes, I have a slight hesitation.

Here’s what goes through my head: “Is it really worth spending the time to make this from scratch when I could just look for it at the store?”

Then I remember, the answer to this question is always yes. There’s a reason that everyone keeps saying homemade always tastes better – because it is 100% true.

The beauty of this recipe is that you can maximize the flavors of the summer garden without using any processed of chemically altered ingredients, so you know that it is fresh. Not to mention, making this tomato jam is a total breeze.

The only major time investment you have to make is while you’re waiting for it to cook down over the stove. But this gives you plenty of time to do other things, and you don’t have to hover!

Clean the kitchen, read a few chapters of a good book, chill with a glass of wine… think of this as an opportunity to get something done that you might not otherwise, or to just sit back, relax, and enjoy those delicious aromas that are wafting over from the stove.

Trust me when I say, once you taste it, you’ll be ecstatic that you decided to make it from scratch.

  1. Wow, Shannon! I’m so delighted to see you post this recipe. It is one of my favorites from the book as well. Your pictures are stunning, and I love all of your ideas about where to use the jam as well. I haven’t made it in awhile but clearly it is time to bring it back!

  2. The Portuguese – style tomato jam is really simple.
    Tomatoes, sugar, the peel of a lemon, sticks of cinnamon, and cloves (optional).

    • Been looking for a traditional tomato jam recipe, finally found one. My mammow used to make all her homemade jams and jellies, from recipes handed down to her. Wish I had some of them. But yes, many including my son whom I taught at an early age cans just about everything. I told him, you just never know when you may need it, always plan AHEAD. Thank you for sharing.

  3. FINALLY! The tomato jam recipe I’ve been searching for! Not too sweet or over seasoned, letting the tomato flavor shine. You’ve even suggested a use or two I hadn’t thought of. Thank you!

    • This particular recipe has not been formulated for canning, and an additional acidic ingredient such as lemon juice would likely need to be added to get the correct pH level for food safety.

      • I’m not incredibly familiar with canning but how much more lemon would need to be added so that I can water bath can these?

        • This recipe wasn’t designed for canning, and unfortunately I’m not able to make any specific recommendations about how much lemon juice should be added for safe water bath canning. You’re right that tomatoes must be acidified in order to can them safely, but the acid content that a tomato naturally contains depends in part on the type that you’re using. Many canners recommend using bottled fresh lemon juice added right to the jars rather than fresh juice to guarantee that the citrus will be as acidic as you need it to be for food safety.

    • You absolutely can, but keep in mind that the final texture and flavor will be a bit different. Depending on how much liquid was added to the tomatoes, the jam may take longer to reduce, or you may want to leave a bit of the canning liquid out. And you may want to reduce the quantity of honey slightly as well.

      Enjoy the party!

    • sounds like a good recipe, but not worth the work for only 3 days in the fridge. How is this saving the taste of the summer? I make tomato preserves, only two ingredients, tomatoes and sugar and can that and put it in a water bath. No lemon juice or pectin required. Lasts at least 18 months on the shelf.

      • An experienced canner like yourself shouldn’t have any problems canning a recipe like this one for shelf storage! Just be sure to test the pH level, since tomatoes aren’t always acidic enough to be canned safely in boiling water for long term storage on their own.

        Water bath canning is best for high-acid foods, while pressure canning is recommended to safely can lower acid foods since pressure canning equipment reaches a temperature of 240°F. Lower-acid ingredients like tomatoes can also be acidified with lemon juice or citric acid to bring their pH level down to 4.6 or lower, the level that is recommended for safe food preservation for water bath canning. And it’s important to remember that water boils at a lower temperature at higher elevations as well!

        For long-term storage without the need for any canning equipment, this jam can be stored in the freezer.

      • Keep in mind, this only makes 2 cups of jam. I expect it would be pretty easy to use 1 cup on making grilled cheese sandwiches for a family. The other cup could be frozen until you’re ready to use it. I think if I made this in a larger quantity, I’d freeze it in 1 cup quantities in small freezer safe jars or containers.

    • Yes, absolutely! Peeling is not necessary, but you could still blanch and peel them if you want the finished jam to have a smoother texture.

    • This recipe was designed for refrigerator storage rather than shelf-stable canning, and acidity levels of different types of tomatoes can vary. Water bath canning is fine for produce with a pH of 4.6 or lower, but a pressure canner should be used for foods with a higher pH that are less acidic, and you may need to adjust acid levels with lemon juice or something similar.

  4. Shannon could you test this wonderful recipe for canning? It is the best tasting recipe. I would love to use my summer tomatoes for gifts at Christmas.

  5. Wow! This tastes amazing as is! I have it simmering on the stove top now and can’t wait! I had some juicy costoluto tomatoes from my garden so if it’s too juicy, I’ll add in some arrowroot powder to thicken, as I just got some today to thicken up a fermented hot sauce I made! I also love savoury flavours, so I added in a pinch of trader joes Umami and its really good!

      • We have not tested this recipe in the slow cooker, but feel free to give it a try. It should cook, but it will take a much longer time. Achieving the ideal consistency will be the only challenge, as cooking on the stovetop without a lid allows more thorough evaporation to take place in a shorter amount of time. You can try on the low setting of your slower cooker for a total of 2-3 hours as a start, check for thickness, and continue cooking as needed.
