Slow Cooker Peach Jam

Delicious Slow Cooker Peach Jam & only 3 ingredients! Take the heat out of jam making & let your Crockpot do all the work for you.

I shouldn’t complain about the weather as I love all the sunshine and it means our produce is growing and ripening well but it’s been over 34℃ in our Kitchen Shed and for me, that’s a tad too warm. The jam making season has well and truly begun, with raspberry jam and josta berry jam already stashed in the pantry ready to remind us of summer when it’s cold and raining. I managed to get another bargain tray of peaches from the supermarket and just in case this might be our last bargain tray I wanted to make some peach jam. Although inspired by Joanne Harris’s description of Vianne making peach jam, the thought of me and a hot jam pan in over thirty odd degrees heat did little for my enthusiasm. Perfect solution: use my slow cooker.
Making jam in the slow cooker is so easy as everything goes in the pot, you give it a couple of stirs and a few hours later you have a bright and tasty peach jam. I wanted a smooth jam so I whizzed it with a hand blender once the sugar had dissolved but you can omit this step if you prefer. Peaches are low in pectin, so added pectin is required to help the jam set. I like to use a packet of pectin (see photo) and sugar but you can buy ready mixed bags of jam sugar if you prefer.

This jam is so delicious I’m not sure it’s going to make it to the pantry, we’ve already had some Slow Cooker Peach Jam with our homemade thick and creamy yoghurt. I feel a scone baking session is required – I’m drooling at the thought !

How to sterilise jars

An easy way to sterilise jars is to pop clean jars in the microwave on full power for a couple of minutes.

Delicious Slow Cooker Peach Jam & only 3 ingredients! Take the heat out of jam making & let your Crockpot do all the work for you.
Recipe type: Slow Cooker
Serves: 4 x 450g jars
  • 1.2 kg peaches, skinned and chopped
  • 2 tablespoons lemon juice
  • 1 kg sugar
  • 1 packet of pectin ( I used Whitworths – see photo. Or you can use 1 kg of jam sugar instead of sugar and pectin)

You will need:
  • A couple of saucers or plates to check the jam has set.
  • At least 4 sterilised jam jars and lids (jars washed on a hot dishwasher cycle and lids if you’re not using new ones sterilised in boiling water for a couple of minutes.)
  1. Place a couple of saucers or plates in the fridge ready to test your jam later.
  2. Add chopped peaches and lemon juice to the slow cooker pot and stir.
  3. Add sugar and pectin (or jam sugar) and stir. Pop on the lid and cook on low for one hour.
  4. Remove lid and stir. (Don’t worry, the sugar is unlikely to have fully dissolved yet)
  5. Scrape down any sugar and replace the lid and cook on low for another hour. Stir your jam mixture and turn up your slow cooker to high – the sugar will have fully dissolved by now.
  6. Replace the slow cooker lid but this time prop it open a little with a wooden spoon to allow the steam to escape.
  7. Cook on high for 2 to 3 hours until set.
  8. Check after 2 hours: drop a small amount of jam on to your chilled saucer. Allow to cool for a couple of minutes and then push gently with your finger tip. If the jam crinkles, setting point has been reached.
  9. Mine did need the 3 hours but it very much depends on your slow cooker.
  10. Transfer to sterilised jars and screw on lids.
  11. Leave to cool.
  12. Store in a cool dry place away from direct sunlight and once opened store in the fridge.
The recipe works well with nectarines too.

I love using my slow cooker for stuff like this. Every fall I make a few batches of apple butter in my slow cooker. I bet this is outstanding!

Yum! I love how easy this is to put together. Such a great use of the slow cooker. I would love to pair the jam with yogurt.

It's time for making those jams! It's something I've never done, but clearly need to get to it, especially now that it's filled with delicious fruits at the farmer's market.

Farmers markets are a great place to get a bargain and making jam means you can preserve some fruit for the winter to remind us of all those summer fruits.
