How to Make Green Tomato Jam

We just had our first freeze of the year and while I was cleaning out my garden to prepare it for winter, I was having a really hard time throwing away the 100+ green tomatoes that I still had on the vine. I planted heirloom tomatoes this year and they were lovely.  I hated to throw them in the yard waste can, it felt so… well… wasteful.

I was telling my friend about this and she said I could make jam out of them.  I thought to myself…  yuck!  who wants to eat tomato jam?  But she assured me it tastes just like any fruit jam.  I was skeptical, but I wanted to try it.  I found a recipe here and modified it as seen below.

I think from start to finish it took me about an hour.  Let me tell you, of all the jams I have had, this has to be one of my favorites and I’m not the only one that likes it.  My son who HATES (although hate is not a strong enough word) tomatoes, absolutely loved this jam.  Loved it.  I didn’t tell him it had tomatoes in it until he ate the entire jar over the course of a week on his toast.  He didn’t believe me.  He said it tasted just like strawberry jam.  Might I mention it may taste better than strawberry jam.


How to Make Green Tomato Jam (that tastes like strawberry jam).

Step #1

Wash tomatoes in the sink using hot water and 1 T. white vinegar.

Step #2

Dice 4 cups tomatoes (unpeeled) and place in a large stock pot.  Turn heat to medium.  Bring to a boil and cook 10 minutes.

Step #3

Using your immersion blender, blend tomatoes until you have fine pieces.  Add 1- LARGE box of strawberry jello and 4 cups white sugar and blend a little more with your immersion blender.  Cook for 20 more minutes. That’s it!


Step #4

Now you can bottle (can) these as I did, or put them in a plastic container and put them in the freezer to make freezer jam.  I processed my jam in a waterbath canner for 25 minutes.  I have been sharing them with my neighbors and they have all liked it and were very surprised it was made from green tomatoes.  I hope you enjoy this as much as we did!

    We made this and all of us thought it was great. Some a good use for all of the green tomatoes I got this year. I did reduce the sugar some and switch out some of the sugar for Splenda though so I can give some to diabetics in the family.

    My jello packs say .88 oz. how do I figure out 6 oz

    1. Good question. I would just use 6 of those. It doesn’t need to be exact.

      1. Actually, that seems like a lot. I think I just used 1 Jello box. The recipe says 6 oz. though, so it’s your call 🙂
