This is the third recipe I’ve tried for onion marmalade, and the first one I’ve been really happy with. While the others have been too sweet, this one is subtle, with delicious complex flavours that were a perfect complement to last night’s sausages and mash.
The most important thing is the slow, slow cooking of the onions – don’t rush this or the texture and flavour won’t be right. Also, I’d strongly suggest you prep your onions with the slicer attachment of your food processor, as 2kg is a lot of onions! Even with the food processor, I shed a few tears – which made me think of the Muppets clip below.
Onion Marmalade
Makes 3 x 300ml jars (Adapted from Preserves by Pam Corbin)
- 100ml olive oil
- 2kg onions, peeled and finely sliced
- 200g brown sugar (original recipe used demerara sugar)
- 150g lilly pilly or quince jelly (original specified redcurrant jelly)
- 300ml white wine vinegar (original recipe used cider vinegar)
- 50ml balsamic vinegar
- 1 rounded tsp salt
- 1/2 tsp freshly ground black pepper
1. Heat oil in a large heavy pan (I used a large Le Creuset pot) over a medium heat and add the onions. Reduce the heat to low, cover the pan and cook, stirring occasionally, for 30 – 40 minutes until the onions are completely wilted and just beginning to colour.
2. Add the sugar and jelly, and increase the heat. Remove the lid and cook, stirring frequently, for about 30 minutes until the mixture turns dark brown and most of the liquid has evaporated.
3. Take the pan off the heat and allow to cool for a few minutes, then add the vinegars (this is important, as adding vinegar to the hot pan will cause it to all steam up and evaporate away). Return to the heat and cook for another 10 minutes or so, until the mixture becomes thick and gooey, and a spoon drawn across the bottom of the pan leaves a clear track across the base for a couple of seconds.
4. Remove from heat and season with the salt and pepper. Spoon into hot sterilised jars and seal with vinegar-proof lids.
Note: the original instructions don’t mention this, but we routinely boil our sealed jars in a hot water bath for ten minutes, ensuring that the lids are covered by at least 2.5cm (1″) of hot water.
[…] marmalade was on the stove this weekend (among other things). Thanks to the sensational Celia for the recipe. This is soooo good. I’m trying very hard to be good and give it time to mellow. I am aiming […]
This looks Wonderful and something I totally want to try next year with my Walla-Walla Onions. But can you tell me what Lilly Pilly is? I live in a rather small town in the US and I have never heard of this, either that or it is an Australian item that I will need to find a substitute for.
I am really enjoying your blog!
Brooke, lilly pilly is an Australian native plant – I’ve posted a bit about them here. We have a big tree growing in our backyard! :)
If you don’t have lilly pilly jelly, this recipe also works well with quince jelly, or even redcurrant jelly, which was the original ingredient specified. Thanks for reading our blog!
Do you mean jelly as in jelly crystals, jelly crystals made up with water into jelly, or jelly in the american sense, i.e. jam?
Tal, jelly as in jam. Like this one…

Thanks. :)
[…] were inspired to make this up when we read Celia’s Onion Marmalade, which by the way sounds heavenly, but, alas I didn’t have a Lilly Pilly tree in my back […]
