Tomato Jam
You’re going to love my easy recipe for old-fashioned Tomato Jam. It’s sweet and spicy with complex yet familiar flavors that can transform even the simplest food into something delicious. This “grown-up ketchup” is the perfect accompaniment for everything from hamburgers and hot dogs to steaks and chicken.
I’m going to tell you something today that I’ll bet you don’t know about me. I love ketchup. Adore it. I eat it like a six-year-old. On french fries; on hash browns; on hamburgers. And, yes, on steak. Especially on steak, much to the chagrin of servers in steak houses all around this area. It’s just not a steak to me without my ketchup.
This Tomato Jam recipe is what I like to call “grown-up ketchup.” It has the usual sweet, spicy, tomato-ey taste of ketchup but is it ever kicked up a notch or three!
This jam is so good it will make you want to rush over the stove to cook something just so you can have a spoonful of this on the side. No kidding.
Use this as a condiment with anything where you’d normally serve ketchup. It’s great on a burger, especially a turkey burger. It’s fantastic with roast chicken and really wakes up your breakfast hash browns. The flavor is rich and tangy with a spicy kick from the red chili flakes.
It also makes a great appetizer – spread a cracker or toasted slice of baguette with a little goat cheese and top with a bit of tomato jam – yum!

🥄 How to Make Tomato Jam
You’ll need 2 1/2 pounds of tomatoes for the recipe. You can use any type of tomatoes that are available, but I prefer cherry tomatoes and often mix red and yellow.
STEP 1. Cut the tomatoes in half or quarters depending on their size.
STEP 2. Combine the tomatoes, sugar, lime zest, lime juice, ginger, cinnamon, cloves, salt, and red chili flakes in a large non-reactive pot.
👉 PRO TIP: If you’re wondering what “non-reactive” pot means, it refers to the kind of metal that a pot or pan is made from. Aluminum, cast iron, and copper are reactive metals; stainless steel, ceramic, glass, and enamel coated cookware are non-reactive. Certain foods when cooked in reactive pots can pick up a metallic flavor or change colors. Tomatoes just happen to do that, so you’d want to use a non-reactive pot for this recipe.
STEP 3. Bring the mixture up to a rolling boil, then reduce the heat to low and maintain a steady simmer.
👉 PRO TIP: Do not cover the pot while the jam is cooking. The moisture needs to be able to evaporate in order for the jam to thicken.
STEP 4. Cook for 1 to 2 hours, stirring regularly until the tomatoes become a soft, sticky, jammy consistency. The cooking time will depend on how high you keep your simmering temperature and may actually take up to 3 or more hours.
👉 PRO TIP: Check the progress and stir occasionally until you achieve your desired consistency. I like mine very thick. My cooking time is actually closer to four hours because I keep my temperature very low. I’d rather cook it lower and longer so I don’t have to watch it so closely. If you simmer at a higher temperature you could risk scorching the jam.
STEP 5. When cooking is complete, remove the pan from the heat. Spoon the jam into a storage jar and keep it in the refrigerator.
Makes about two pints.
❗ Recipe Tips
- Cooking time will depend on your simmering temperature and desired thickness. It may take 3 hours or more for the mixture to reach the correct consistency.
- Make sure to use a clean, sanitized jar for storage.
- This is not a canning recipe. It’s not shelf stable and must be stored under refrigeration rather than in the pantry.
🔀 Variations
- Change the color by using all yellow tomatoes.
- Add a dash of liquid smoke for a smoky tomato jam.
- Stir in a bit of curry powder for a curried tomato jam to use in Indian dishes.
- Use lemon juice and zest instead of lime for a bright citrus flavor.
- For a more Asian flavor, add a teaspoon of toasted sesame oil.
🍚 Storing and Freezing
- Storing: Store the cooled jam in jars with sealed in the fridge. Use within 3 weeks.
- Freezing: You can freeze the cooled jam in a freezer safe zip-top bag or plastic container for up to 3 months. Thaw completely in the fridge overnight before using.
❓ Questions About Tomato Jam
Glad you asked! It’s actually great on a grilled cheese sandwich. Or try it on buttered toast with cream cheese. Some people like to use it as an on-the-side condiment with meat pies, particularly beef. You can also use it as the topping on a meatloaf, or on a meatloaf sandwich. Basically, anywhere you’d use ketchup, you can use tomato jam.
I personally like using cherry tomatoes because they don’t have as much juice as other tomatoes. The juicier the tomatoes, the longer you’ll have to cook your jam to get to the thick, sticky consistency of jam.
In order for the jam to thicken, the moisture needs to evaporate off during cooking. Because slow cookers hold moisture in, I don’t recommend using a slow cooker for this recipe.

I peeled the tomatoes first because its been so hot here that some of the skins are tough. I even peeled the little yellow pear tomatoes. I cooked the mixture for about 3hours and then did a water bath so I could store the jam longer.
MaryLou — This is not a canning recipe. A water bath will not make it shelf stable or safe. It must be stored under refrigeration.
Increased ingredients:
1 TBLS freshly grated ginger
1 tsp cinnamon
1/2 tsp ground cloves
2 tsp Himalayan Pink Salt
Prep time 1 hour to quarter 2.5 pounds of mixed cherry tomatoes.
Cooked in slow cooker without lid, after bring to a boil on range, for 8 hours.
We love the zestier version on toast, cracker & cheese, and meats.
I made this yesterday, and used it on lamb chops. Very good.
I was concerned about the tomato peels, so I laboriously quartered the tomatoes, thinking that smaller peels would be better. First bite I took, got one of those peels that sticks to your teeth. Several rude words were said. When the jam was done cooking (a bit more than 3 hours), I put it through a food mill, which made the consistency perfect.
Great recipe.
Thanks,
Joe
My husband loves this – eats it regularly. He puts it on many things especially his favorite breakfast quesadilla.
Thanks for letting me know! I think tomato jam on quesadillas sounds great, too :-)
Is it cardamon or cinnamon?
It’s cinnamon. I’ll edit the text of the post.
can this be made in crock pot
Hi Ann — The moisture needs to be able to evaporate during cooking in order for the jam to thicken. Because of that, a slow cooker is not recommended for this recipe.
Have you ever had trouble with the skins breaking down?
Hi Britteny – I’m not sure exactly what you’re asking about the skins breaking down?
The skins or peels all rolled up after the tomatoes cooked down and they get stuck in your teeth and the roof of your mouth. I keep gagging on them. The flavor is so good, but the peels are awful.
Wow, no, I’ve never had that to happen. Cherry tomatoes usually have really thin, tender skin and it almost disappears into the mixture. I’d suggest processing it through a food mill, or in a food processor maybe. You could even press it through a fine mesh metal sieve to remove most of the skins if you wanted to.
I think it would probably work great in the crock pot, Debbie!

I made this jam last year. Loved it and mad another batch and canned it. We just had some the other evening with goat cheese and crackers and it seemed to be perfectly fine. A big hit with all of our friends!!
You’ve reminded me that I need to make a batch of this! We enjoy with all kinds of things in place of catsup.
Thank you! This is one of those things I have been looking for. The best appetizer I’ve ever had was a wedge of Brie, roasted garlic, tomato jam, a few baby greens,all served with pita points. The flavors,tasted all together were fantastic.
PS I’m still finding interesting recipes as I continue exploring your blog.
That sounds really delicious, Shelby. I can’t wait to try that for myself!
I just made this with cherry toms from my garden – it was my first ever jam and it was SO easy and tastes really good! Thanks a lot – I will definitely be making more!
Glad you liked it, Clare. Reminds me that I need to make some more!
I just made this last night in the crockpot. Cooked on high with the lid half off for 12 hours. Totally easy and boy did my house smell yummy. Thanks for the great idea.
Hey can you think of any reason why you couldn’t waterbath can this?
Yes, I can. It’s probably not acidic enough for water bath canning. Honestly, I don’t take chances with canning anything that hasn’t been tested and approved for canning by USDA. And this is not an approved canning recipe.
I made this today. What a great way to use up cherry tomatoes! I’m not a ketchup fan, so I am not sure what I’m gonna try it on first. LOL I really like the taste though. I’m gonna can it for gifts. I know some people who will love it! I didn’t care for the skins, so I hit it with the stick blender.. that made it better for me… Thank you for this interesting and yummy, super easy in the crock pot recipe!
It may sound like I wasn’t crazy about it… but it’s really good and perfect for me since I’m down and out with my back.. leaving it to cook in the crock pot was so fun!
Joyce – I’m so glad you enjoyed making the tomato jam and hope you really enjoy using it! You said you planned to can it for gifts. Just be aware that this is not an approved canning recipe. It hasn’t been tested to determine whether it has the required pH to make it shelf-stable. You could, however, certainly pack it into jars to keep in the refrigerator and tell your recipients to do the same :-)
Thanks for this great recipe, Lana. I’ve made it several times, with a couple of slight adjustments. I add a couple of shallots, and reduce the sugar somewhat. I actually canned this and gave it as Christmas presents to several friends this year, and it went over really well! YUMmmmm!
I’ve never made tomato jam and it looks fabulous! I love the sweet and spicy. It is definitely something that sounds good spread on a cracker for a little snack. I love that kind of snack!
How long will it keep in the fridge?
I don’t really know just how long this will keep in the fridge. It never lasts long enough around here to test that. To be safe, I probably wouldn’t keep it more than a couple of weeks.
I loved this jam. Such breathtaking photographs! I loved your site.
seriously beautiful photographs and what a wonderful recipe!
