I’m amazed I haven’t shared my red onion marmalade recipe with you before now. It’s something I make all the time as it is just so damn useful and tastes amazing too.
Red Onion Marmalade/Chutney
So is this red onion preserve a marmalade or a chutney? It’s a wee bit confusing really name-wise. A marmalade is normally considered something to do with citrus fruit.
But this looks much more like a chutney and there is no citrus at all. Actually no fruit at all either.
Whether you want to call this a marmalade or a chutney you will have to agree on one thing, it’s delicious!
Onion relish
This is one of those savoury preserves that just ticks all the boxes for me. It is super easy to make. It just takes a little time. But not much real hands-on effort.
This onion marmalade is sticky and rich. It packs a hefty punch of flavour yet is sweetly soft in the mouth.
There are grown-up flavours here that make you want to break into a packet of crackers and reach for your finest cheese.
Ingredients for Red Onion Marmalade
Red onions, olive oil, some salt and soft brown sugar.
Now for those all-important extras that make this onion jam so special; red wine, balsamic vinegar and some red currant jelly.
The red currant jelly is purely optional.
I often use my own Cumberland Red Currant Jelly or my Rowan and Red Currant Jelly for this recipe.
Can you use brown onions in onion marmalade?
Yes, of course, you can. There will be a difference in the flavour but you will still have a rich and luxurious onion marmalade.
So just use whatever onions you have to hand.
Slicing onions
You want to finely slice your onions for this onion chutney. Either use a mandoline (please be careful and either use a guard when grating on a mandoline cutter or use one of those mandoline gloves.
Carmelised onion jam
You want to carmelise those onions. That means making them sweet and oh so tender by slow and low cooking.
The onions will be all melty and sweet, almost toffee-like. To get this effect I like to cook my onions in olive oil with the salt for about an hour.
Cover the onions with a piece of scrunched up and slightly dampened baking paper. This helps to make the onions sweat down.
Once my onions are all soft and gooey and seriously sweet I add my other ingredients to the pan.
First comes the sugar. Stirred in and allowed to melt into nothing. Raise the temperature and get the jam to boil.
Then add the red wine and balsamic vinegar. Finally, that spoonful of jelly if you are using it.
How do you know when onion jam is ready?
The onion marmalade is rich and thick when it cooks. Once you can drag your wooden spoon through the mixture and leave a clear trail on the bottom of the pan your onion marmalade is ready.
Carefully ladle the hot preserve into sterilised jars.

How to use onion marmalade
This rich and almost creamy sweet and savoury onion preserve is incredibly useful. Yes, it is totally addictive to folks like me who can eat it straight from the jar and forgo the crackers completely.
However, served with a cheeseboard this onion marmalade is a revelation.
As part of the great British Ploughman’s lunch instead of the standard pickle. Think outside the jar my friends!
Spoon a little of your onion jam into simple soups like tomato or potato. It will give an extra dimension of taste and texture.

Onion marmalade for the perfect gravy
But my favourite way of using my red onion marmalade is when I’m making gravy. This is particularly true at Christmas.
Using your carmelised onion marmalade stirred into your homemade gravy gives all that amazingly rich sweetness of the onions without having to do the work.
The onion jam will do the work for you, making your turkey gravy deeply flavoured, rich and aromatic. It will have far more character and have your family and friends asking for more every time.
I use mine in all my gravies from beef to turkey, chicken to pork.
How much does this onion jam recipe make?
You will get one big 500ml jar from this amount of onions. Or a selection of smaller jars. I like to make smaller jars as this luxurious carmelised onion jam makes the perfect wee foodie gift to add to my Christmas hampers.
