Green Tomato Relish
It's happened to us all: summer ends too early, the cold weather arrives, and your beautiful tomato plants are covered with glorious tomatoes... but they're still green! Not to worry, you can still save them and turn them into a deliciously spicy Green Tomato Relish.

OK, I’m the first to admit it. As much as I looove food and eating, gardening does not come easy to me. Most years I keep at least my kitchen herbs alive, but I’m often on the go and my other plants suffer.
This year though, we had a new terrace and space for loads of delicious plants. After many happy months harvesting, autumn has arrived with a bang and we’re left with a few bunches of green tomatoes. So if you’re wondering what to do with green tomatoes, allow me to introduce: Green Tomato Relish or chutney.

Why You’ll Love This Recipe
‘Love Food, Hate Waste’ should be every good cook’s mantra, and after a summer of dutifully tending your tomatoes, it would be an awful waste to chuck the last tomatoes just because they arrive a little late.
This recipe is perfect for using up the last of the summer toms! It’s small batch, so you can start with as little as 500 g / 1 lb of tomatoes. I like to mix in some green bell pepper to stretch things out a little and add some green jalapeños for extra zing. It’s SO delicious and great on a cheeseboard or sandwich.
Ingredients
To make my Spicy Green Tomato Relish recipe, you’ll need the following main ingredients:
- Green Tomatoes: The reason we are all here! I had a mixture this year of larger tomatoes and some very late green cherry tomatoes. They’re all good here, just chop them up to about the same size.
- Green Bell Pepper (Capsicum): A great add-in if you don’t have quite enough tomatoes to make up 500 g. Remove all of the bitter white pith inside.
- Jalapeños: My favourite chilli pepper! I use two and scrape away a few of the seeds if I test them and they seem a bit too spicy. If you love spice, add some more.
- Onions: Plain white or yellow cooking onions are best for this recipe.
- Spices: I like the flavour of the tomatoes to shine here, so I don’t use too much to get in the way. Lemony coriander seeds (lightly crushed), mustard seeds, turmeric, and a bit of celery salt. Yum.
- Sugar, Salt, and Vinegar: Even though you can’t keep tomatoes lovely and bright green after cooking, I use white sugar and white vinegar for the best possible colour.
The complete ingredient list and detailed instructions are in the recipe card at the bottom of the page.
Instructions
Once upon a time I had a stall at the markets selling pickles, chutney, jam, and other preserves (thousands of them!), and let me tell you, Green Tomato Relish is one of the easiest. There are only three main steps!
- Wash and chop all your vegetables, and sterilise your jars.
- Combine the vegetables, spices, salt, sugar, and vinegar in a saucepan, bring to the boil, and simmer for around 45 minutes.
- If you fancy, you can thicken the relish with a touch of corn starch. Otherwise, the last step is to bottle it up in the jars and enjoy!
Frequently Asked Questions
Do I have to water bath can this relish?
Due to the high levels of sugar, salt, and vinegar in this recipe, it is not necessary to water bath can it, as long as you are using sterilised jars. If you have concerns, you can absolutely process it in a boiling water bath for 10 minutes (or keep the sealed jars in the fridge)
Can I make a bigger batch? I’ve got LOADS of green tomatoes!
Of course! Just scale everything up. You’ll find it takes longer to cook down though, as the tomatoes will reduce more liquid.
What do I do if I’ve still got lots of red tomatoes left over?
I’m so glad you asked! Definitely make my Homemade Tomato Relish, one of my very most popular recipes. Or you could try a Slow Roasted Tomato Sauce?
