How to make…Harvest Ketchup

In our household, we use more ketchup than any other condiment. We use it for hot dogs and hamburgers, but it also gets used in soups and stews, and even to fortify gravy. So, this year, in addition to making tomato sauce, I also made several batches of harvest ketchup.

It’s called “Harvest Ketchup” because it uses up all the veggies that we had in our harvest and cupboard. Onions, peppers, carrots, celery… I didn’t go so far as to add any other leafy greens, cucumbers, or zucchini, but the thought did cross my mind.

The key to ketchup is low and slow. It takes A LONG TIME to get it cooked down to the thickness of a good ketchup. We’re talking hours. As you’ll see in my video, this particular batch was probably canned while it was still pretty saucy, but that’s okay. Since so much of our ketchup is used in cooking anyway, we’ll get away with it.

For me, there are two “secret” ingredients to harvest ketchup: cloves and molasses. I strongly urge you to use at least a little of both of these if you go ahead and try to make harvest ketchup for yourself.


4PoundsRipe tomatoesChopped (strain to reduce liquid)
2-3MedumBell peppersChopped
5SticksCeleryChopped (or use celery seed)
2ClovesGarlicFinely chopped (or use garlic powder)
1CupApple cider vinegar
1CupBrown sugarPacked
1tspBlack pepper
Hot sauceJust a couple dashes, to taste.


  1. Chop all the vegetables and add to a large pot.
  2. Add the vinegar, sugar and other spices.
  3. Simmer on low (250 F), uncovered, until the onions are translucent; about an hour.  Stir occasionally.
  4. Carefully blend the hot mixture on very high speed until smooth and emulsified.
  5. Transfer back to the pot to continue to cook down (uncovered) and thicken, adding the molasses and hot sauce, if using.  Stir occasionally to avoid burning, especially later in the cooking process.
  6. Ketchup is done when it’s reached the thickness you prefer.  Consider using a roaster to cook it low and slow overnight.
  7. Transfer while hot to jars and process in a hot water bath for 10 minutes or more, depending on your altitude.
  8. Store in a cool, dark place for up to 18 months, checking seals periodically.
