Got Tomatoes? Make Your Own Ketchup
I think if we are going to discuss tomatoes, the issue of classification (fruit or vegetable) should be cleared out of the way at the outset.
Botanically, tomatoes are indeed fruit. This is a fact of common knowledge, yet although people are quick to point it out, they hardly consider treating them as such. One would no more make a sweet and cinnamon-scented crisp out of tomatoes than they would spread fresh apples on a pizza. (Although come to think of it, either one might be quite tasty.)
And that’s because tomatoes – are you ready for this? – are vegetables. The term is purely culinary, referring to any plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are used as food. So from a culinary standpoint, from the arena in which it matters (the kitchen), a tomato is a vegetable. But whatever you call it – I’m just happy that my plants are producing some.
(In case you do get pulled into the fruit vs. vegetable debate, you can play the Supreme Court card: legally, tomatoes have been considered vegetables since the late 1800s when the US imposed tariff laws that included a duty on vegetables but not fruit, forcing the court to decide; furthermore, tomatoes are the state vegetable of New Jersey – 8,682,661 New Jerseyers can’t be wrong.)
In late summer, tomatoes are at their prime – and it’s often necessary to use up bushels of them at a time, or find a use for those that have become bruised or are past their prime. Homemade jam and preserves are hip this year – so why not make your own ketchup? It’s simple to make with fresh tomatoes (and a great use of those that are starting to go wrinkly) and so much healthier than the processed kind, which contains more sugar than ice cream does. Add spices to suit your taste – cinnamon, cloves, paprika, celery seed, peppercorns, bay leaves and fresh basil are commonly simmered into homemade ketchup, or try thinly slicing a bulb of fresh fennel and adding it to the pot. If you have a slow cooker, toss everything in and cook on low for 6-8 hours.
Homemade Tomato Ketchup
If you like using your slow cooker, try tossing everything in (except the oil, since you won’t be sauteing the onion) and cook on low for 6-8 hours, then puree.
canola or olive oil, for cooking
1 purple onion, chopped
2 garlic cloves, peeled (optional)
10 medium tomatoes (about 3 lbs.), roughly chopped
1 5.5 oz (156 mL) can tomato paste
1 cup packed brown sugar
1/2 cup red wine or apple cider vinegar
1 tsp. salt
pinch dried red chili flakesIn a large pot, heat a generous drizzle of oil over medium-high heat. Add the onion and cook for 5-7 minutes, until soft. Add the garlic and cook for another minute, then add the tomatoes, tomato paste, brown sugar, vinegar, salt and chili flakes and bring to a boil. Reduce the heat and simmer, stirring occasionally, for an hour or so or until very soft and fairly thick.
Using a hand-held immersion blender, puree the mixture right in the pot, or cool and transfer in batches to a blender and puree until smooth. Seal in sealable jars according to the manufacturers’ directions, store in the fridge for up to two weeks or freeze for up to six months. Makes about 2L.

Bettina commented on Aug 23 10 at 9:14 amCan this recipe be processed and canned? I’ve always wanted to make my own and this looks like the perfect recipe. Thank you for posting
Kelly commented on Aug 24 10 at 5:13 pmCan splenda be used instead of the brown sugar?
JulieVR commented on Aug 25 10 at 1:41 pmJust so you know – Brown Sugar Splenda has EXACTLY the same amount of carbohydrates and MORE calories than plain old brown sugar! The reasoning is that you’ll use less of it, because it tastes sweeter.. but I don’t think most people do. And in fact many people eat more because they think of it as a freebie. I haven’t tried it with Splenda but I don’t see why not if you like the flavor. Usually artificial sweeteners work well in things like sauces.
JVB commented on Sep 18 10 at 2:46 pmYou DO need less of the Splenda Brown Sugar. A little goes a long way. All you’re wanting is that brown sugar flavor…go easy on it and you WILL save calories and carbs.
ShojoBakunyu commented on Sep 18 10 at 3:43 pmBrown Sugar tastes like that because it has Molasses added back in to it. You can use 100% splenda with an added spoonful of molasses for that Brown Sugary Goodness.
becca commented on Sep 18 10 at 4:06 pmInstead of using Splenda which is SO bad for your health try using stevia. It has no health side effects and actually support good blood sugar levels. It’s taste doesn’t change when heated.
wvhomecanner commented on Sep 18 10 at 4:39 pmYes, you could can this – I would skip the oil and just simmer the onion and garlic with the rest of the ingredients. Increase the vinegar to 3/4 cup and can in a boiling water bath for 10 minutes.
Holly commented on Sep 18 10 at 5:16 pmWhy go to all that trouble to make this and use Splenda??????
mariann h commented on Sep 18 10 at 5:18 pmIn the summer fresh tomatoes are great, but how about in the winter? what do you think of using hi-quality canned tomatoes. Its just me and I dont use much but would like to make my own.
Cindy Merrill commented on Sep 18 10 at 5:47 pmUse 1/4 cup blackstrap molasses instead of brown sugar, and add 1 cup stewed rhubarb: My husband said he proposed to me because I made some for him.
JulieVR commented on Sep 18 10 at 6:04 pmOh yes, I’m sure you don’t need as much… but people tend to use as much or more when they think of something as healthier or a calorie “freebie”!
Sandra commented on Sep 18 10 at 7:11 pmCan you freeze it in jars, or should it be in some other container?
Margey commented on Sep 18 10 at 7:44 pmI’ve made my own ketchup (not this recipe) without any sweeteners and my kids love it. My problem is that it ends up solidifying, and I have to keep adding water and after a few days I have to through it out. How does this recipe hold up? What is the consistency like after a few days?
pat conner commented on Sep 18 10 at 9:34 pmdoes anyone know the calorie count mon this.
Michael commented on Sep 18 10 at 10:06 pmShouldn’t diabetics use the splenda instead of the brown sugar?
Pat commented on Sep 18 10 at 10:07 pmSplenda is the worse thing for you. Better to use
the brown sugar. Looking forward to trying this.
sue commented on Sep 18 10 at 10:20 pmi am confused does that mean an apple is a vegetable too?
keith commented on Sep 18 10 at 10:22 pmCan you make this ketchup with lemon juice instead of vinegar?
nancy martin commented on Sep 18 10 at 11:03 pmI also would like to know if the ketchup can be canned? I use a water bath method.Thank you
JB commented on Sep 18 10 at 11:18 pmLooks good except that is waaaay too big of a batch. I’ll never use that much up in two weeks and I hate to freeze things for very long.
eliza commented on Sep 18 10 at 11:40 pmIt’s good to know that splenda can be substituted. After having gastric bypass surgery it’s hard to digest anything with real sugar. Processed foods also make me sick so knowing that homemade ketchup is possible is quite neat and I can’t wait to try this recipe. Thank You for posting.
LLZEE commented on Sep 19 10 at 12:45 amsplenda of any variety is not good for you
sandra jordan commented on Sep 19 10 at 3:20 amartificial sweetners are worse for you than regualar sugar..
tanya commented on Sep 19 10 at 3:47 amdo you need to add water to the large pot?
Rei commented on Sep 19 10 at 3:50 amYou don’t get out much do you? Well let me school you in the worldly matters of tomatoes. Tomatoes in China ARE considered a fruit- they typically eat them sliced and covered in white sugar as an appetizer…and they are ALL appalled when any American (me) asks them to hold the sugar in favor of salt and pepper. They think that eating a tomato with anything other than sugar is down right revolting. (Oh and by the way no self respecting Chinese would ever eat a pizza with sliced tomatoes!)
Got a hankering for dried fruit? Well then another big hit here in China is dried cherry tomatoes! They eat them the way we would eat raisins or any other dried fruit. All in all they actually aren’t that bad and can be used in a variety of recipes (specifically a replacement for raisins in our house).
But on the next pizza point- that you had mentioned “fresh apples on a pizza” you are WRONG on another count! In Asian countries (China, Japan, AND Korea) a fruit pizza is more common than a pepperoni! They cover the pizza in fruit (usually apples, pears and what ever their ‘specialty’ might be) and then instead of a tomato sauce they cover the whole thing in “salad dressing” (that’s their translation for mayonnaise)!! In some cases they even add chicken meat or shrimp to the pizza as well but most stick with just fruit and call it a ‘dessert pizza’.
Just thought you should know! :P 8 years living in China- no end in sight!
Ron commented on Sep 19 10 at 4:55 amTry to keep the tomato seeds out of the equation. They add a nasty aftertaste . They can be stopped with a funnel seive.
liz commented on Sep 19 10 at 8:53 amyou shouldnt use splenda, period. When you heat the product it turns into liquid poison. Everything in moderation. If you have anything have it reduced. Reducted fat, reducted portions, etc. If you get something fat free, they need to replace what they are taking out with some sort of man made filler that is usually harmful to your body. Just use the real sugar and eat less of the stuff.
Betty Dickerson commented on Sep 19 10 at 8:54 amI have tried to use sweetners in canning and it does not turn out the same. Has a bitter flavor and the Ketshup did not thicken down as it should. But who knows you may have success, try it with a small amount.
MMS commented on Sep 19 10 at 10:49 amOkay, pardon my ignorance, but do you cut the tomatoes before adding them to the pot or just add them whole? What about the skins — when you do Canned tomatoes you get rid of the skins, do you get rid of the skins for this or do you just puree everything together? Thanks for your help!
JulieVR commented on Sep 19 10 at 11:22 amTanya – no.. the juices from the tomatoes are enough! Nancy – I’m sure it can be, but I’ll leave that up to your discretion.. I haven’t done it myself, and don’t want to give unsafe canning advice! MMS – yes, sorry! Give them a bit of a chop. Although I have done this in the slow cooker and left them whole. And no, I don’t get rid of the skins – they contain much of the fiber, and get pureed in anyway!
Ricardo commented on Sep 19 10 at 11:48 amJust the aroma of the ketchup simmering is worth the effort to make it. Needn’t mention how much better it tastes.
Marcia commented on Sep 19 10 at 1:05 pmWhen I was about 6 (early 1950′s), we were having a Christmas gathering at my grandmother’s, and my favorite aunt was coming. This aunt was noted for her gourmet cooking, and always brought something especially delicious. My sister and I overheard her saying she had brought a new recipe: Pizza Pie. Wow! Pie! Sis and I were drooling.
When she served her pizza, made with Tomatoes and cheese, we were appalled. No way were we touching a pie made of tomatoes! Uck!
Of coursem by the time we were teenagers, we wouldn’t eat anything else.
Demi commented on Sep 19 10 at 8:35 pmAnd, why would I care about tomatoes in china? It is probably full of pesticide and pollution.
Al commented on Sep 19 10 at 10:49 pmWhere are all the sources from people saying Splenda is bad for you? There are only a couple studies saying it’s bad, while there are over a HUNDRED saying that it has no toxic effects. It’s sugar with 3 chlorine atoms (an atom that is already found in abundance in your body). Any study claiming that Splenda is carcinogenic needs to be taken with a grain of salt; the levels of Splenda consumed by the lab animals are probably ridiculously high. For example, aspartame is “known” to cause cancer, right? But in order to have the same proportion of aspartame in your body as those experimental rats, you’d have to drink over 800 cans of Diet Coke A DAY. …Something to think about before you let mainstream articles skew your perception of sugar substitutes.
Emily commented on Sep 20 10 at 12:36 amAl, say what you want to defend Splenda, but I know for a FACT that it gives me migraines (and several other people I have talked to). That cannot be good for anyone. And I do believe that the claim on the news a few years back is that aspartame can burn holes in your brain. It was said that the chemical that they use in artificial sweeteners is okay to use because it is derived from fruits, but without nature’s other chemicals (in the fruit) to balance it out, it is potentially harmful. So, do what you like, but I will never use an artificial sweetener.
melissa commented on Sep 20 10 at 12:53 amI don’t believe in artificial sweeteners, but I also don’t believe in pharmaceuticals. But what I do know is that something in the aspartame closes my throat in no time. This homemade ketchup looks so good by the way.
Katie commented on Sep 20 10 at 2:16 amSplenda does not contain aspartame… most of the other sugar substitutes do, including some of the Crystal Light products. Read the ingredients.
Kevin commented on Sep 20 10 at 6:07 amWow I had no idea people who cook at home could have no knowledge of food of other countries. I mean American foods are based on Italian, French, and yes even Chinese foods. I must say that the whole Spinach containing E. Coli was made in America. Do you know what caused that? E. Coli lives in the intestines of animals. Can you guess how the two come in contact? Yep fertilizer not pesticides. Plus how can you claim a poor country would something expensive like pesticides. An uneducated person thats who. I am living in China and vegetables as well as fruits are cheap. Do you know why? Because they are made here and not shipped from other countries like oh say bananas and kiwis which are not native to our lands. I really wish people would become educated before throwing around accusations against other countries. Also Americans tried to sneak cloned cattle into the U.K. without telling them. I for one don’t trust my government at all after that. Since it is not proven to be clear that cloned animals are safe to eat.
Debi commented on Sep 20 10 at 8:01 amRecipes like this one appeal to many people. People who have a problem with Splenda shouldn’t use it but shouldn’t try to put their opinions on others. Each person should be allowed to make their own decision. If you can’t have any sugar at all and you have had no allergic reaction to Splenda, then use it. It’s better than most other choices, except may Stevia.
I get tired of all these people trying to push their ideas on others. We’re all adults and can decide for ourselves what we want to eat or not eat.
Awotarsing commented on Sep 20 10 at 10:31 amThis is most wonderful but its origin is in mauritius found in Indian Ocean
Awotarsing commented on Sep 20 10 at 10:32 amit was discovered in india
Lynn commented on Sep 23 10 at 6:06 amI would definitely cut back on the sugar if I made this recipe again – it is way too sweet, but I figure if I mix it with some horseradish and hot pepper flakes, it will make a great chili sauce.
Aiva commented on May 29 11 at 9:03 pmOkay, I cannot believe the “You don’t get out much, do you?” comment was not considered “hostile”. Let’s condescend a little bit less, and work together to find solutions, eh?
Only Del Monte Ketchup for me commented on Nov 06 11 at 9:45 pmI want my ketchup, especially 2 liters of ketchup as this recipe provides, to last longer than two weeks in the refrigerator!
Amanda commented on Jan 24 12 at 3:44 pmThank you very much for posting this recipe! I’m very excited to try it! :)
emily commented on Jan 26 12 at 2:02 pmNot only does this not sound like katchup, but sounds like runny, watery, not spicy salsa. What kind of tomatoes are you using? Why use a can of tomato paste when you can make that yourself too? This one is not worth it.
