Can be used it lots of different ways.
A money saving recipe made from scratch.
I love recipes that you can make from scratch and homemade chutneys are not only a great way to preserve ingredients, making them last longer, but there are so many variations of flavours you can try.
This caramelised onion chutney uses simple ingredients you can find at most supermarkets or grocery stores and with a little patience, it’s quite easy to make. Making your own chutney means that you know exactly what has gone into your food and the flavour is also much better.
There are many different ways of using this red onion chutney. You can add it to gravy, pop it on a pizza, use it as a filling in sausage rolls, add it to a burger or hot dogs and so, so many more things! I really love adding this to a cheese board or cold meat platter. You can even give your onion chutney away as a homemade gift to friends and relatives.
What’s The Difference Between Chutney and Jam?
Chutney is a type of Jam that you would typically associate with a savoury flavour. Jam has a sweeter flavour. However, since Chutney is essentially a jam subcategory, Onion jam or even red onion relish can sometimes be used to describe recipes like this. I have seen it packaged as an onion jam many times before, there isn’t usually much of a difference between the taste of the two. Usually, the preservatives of a chutney not only include sugar but also a type of vinegar and can be a mix of both vegetables and fruit. Jam typically contains fruit only.

Equipment Needed:
- Large Saucepan or Heavy-Bottomed Pot: Choose one that will fit all the ingredients in comfortably without them spilling over the sides. A pan with a heavy base is best as it will cook the chutney more evenly and helps to prevent the onion chutney from burning as it cooks.
- Wooden spoon or Heat-Resistant Spatula: My preference is a spatula, as you can scrape the base of the pan when stirring so nothing sticks.
- Sharp Knife and Chopping Board: For prepping the ingredients. You can also use a Mandoline slicer to get a really fine, even cut with the red onions. Alternatively, you can use a food processor with a slicing blade to cut your onions. Just be sure not to puree them, you want your caramelised onions to remain somewhat chunky.
- Grater: To grate the ginger before adding to the mixture.
- Measuring Equipment: For best results always measure your ingredients accurately.
- Sterilised Jars With Lids: This onion chutney recipe yields about 700-800ml so you’ll need approximately 2-3 medium-sized jars for storage. To help prevent mould, lids with rubber seals and waxed discs also come in handy.
- Funnel (optional): You can use a funnel when jarring the chutney for ease or a just large spoon.
Ingredients:

- Red Onions: I wouldn’t recommend using any other type of onion such as yellow onions or white onions as the flavour of a red onion is much milder than it’s counterparts. The onion flavour will be too strong and won’t taste sweet.
- Olive Oil: Just a splash of oil helps the onions to cook.
- Dark Muscovado Sugar: Using this dark sugar really helps give the chutney a rich flavour and deep colour.
- Balsamic Vinegar: Use a good quality balsamic vinegar for the best results. Do not use balsamic glaze.
- White Wine Vinegar: Not only does this help to preserve the onion chutney, meaning you can store it for much longer, but it balances out the sweetness of the sugar
- Dark Brown Soft Sugar: Sweetens the chutney and helps thicken it to a jam-like consistency.
- Salt: For seasoning to enhance the flavours.
- Garlic: Use fresh garlic and grate or crush the cloves for better consistency. You can also use garlic puree
- Fresh Ginger: Use fresh, peeled ginger and grate it finely. You can also use lazy ginger but do not use stem ginger.
Substitutions and Additions:
Wondering if you can substitute or add an ingredient? Here, I will tell you if that’s possible.
Substitutions:
- Dark Muscovado Sugar: Replace with more dark brown sugar. However, keep in mind muscovado has a richer, molasses-like flavour, so the end result might have a slightly different flavour. I wouldn’t recommend using white sugar.
- White Wine Vinegar: Substitute with apple cider vinegar if needed.
- Olive Oil: Use any neutral oil like vegetable or sunflower oil if needed or even a knob of butter.
Additions:
- Thyme or Rosemary: Fresh herbs like thyme or rosemary can add an aromatic, earthy note to the chutney.
- Bay Leaves: Another good addition for extra flavouring.
- Black Pepper: You can add some crushed black pepper if you wish, for extra seasoning.
- Chilli Flakes: If you like things spicy, add some chilli flakes or a finely chopped, deseeded red chilli pepper to the mixture.
- Cinnamon Stick: A small cinnamon stick simmered in the chutney can provide a subtle warmth and festive flavour.

Step-By-Step Guide – How To Make Caramelised Onion Chutney

Frequently Asked Question
Muscovado sugar has a deep, molasses flavour that enhances the richness of the chutney. Dark brown sugar also adds sweetness but with a less intense flavour. Together, they create a balanced sweetness with complexity.
The chutney should be thick and jam-like once it’s ready. The liquid should have reduced, and the onions should be soft and glossy. If it’s too runny, continue to simmer it until it thickens.
You can eat the chutney as soon as it cools, but for the best flavour, it’s recommended to let it mature for at least a month. The flavours will deepen and meld together over time.
Mastering This Recipe – Expert Tips
- Have patience with the onions: Be patient when cooking the onions. Cook them slowly over medium-low heat until they’re very soft and caramelised. This process brings out their natural sweetness, which is key to the flavour of the onion chutney.
- Don’t rush the simmering time: Don’t be tempted to turn up the heat and rush the cooking process. Not only will you risk burning the chutney mixture, it might not thicken well, and you’ll end up with runny chutney as a result.
- Watch the mixture not the clock: The cooking time can vary depending on many factors including the thickness of the onions or the type of saucepan you use. It may need slightly less time or a little more time to produce the right consistency.
- Warm Jars For Canning: Be sure to keep your jars warm before placing your chutney inside, never add hot chutney to cold jars as they could crack.

Storage
- Transfer the hot mixture it to warmed, sterilised jars, place a waxed disc on top of the chutney and seal the lid tightly.
- The wax discs help to create an airtight seal to your chutney, which prevents mould from creeping in. You should pot up your onion chutney while it’s still hot (make sure the jars are warmed too to prevent cracking).
- Store the jars in a cool, dry, dark place, such as a pantry or cupboard. The chutney will improve in flavour over time and can be stored for up to 6-12 Months unopened.
- After opening, keep the chutney in the fridge. It will stay fresh for about 4-6 weeks.
- I don’t recommend freezing red onion chutney.

Caramelised Onion Chutney – With Red Onions
Ingredients
- 550 g Red Onions, finely sliced
- 3 tbsp Olive Oil
- 3 tbsp Dark Muscovado Sugar
- 2 tbsp Balsamic Vinegar
- 150 ml White Wine Vinegar
- 150 g Dark Brown Soft Sugar
- 1 tsp Salt
- 1 Clove of Garlic
- 5 g Fresh Ginger, finely grated
Instructions
- Heat the olive oil in a large saucepan over medium-low heat. Add the finely sliced red onions and cook gently for about 20-30 minutes, stirring occasionally, until the onions become soft and start to darken in colour.
- Once the onions are soft, add the dark muscovado sugar and stir it through the onions. Continue to cook for another 10 minutes, allowing the sugar to dissolve and caramelise the onions slightly.
- Add the balsamic vinegar, white wine vinegar, dark brown soft sugar, salt, finely grated ginger, and the garlic clove to the saucepan. Stir the mixture well to combine all the ingredients.
- Reduce the heat to low and let the mixture simmer gently for about an hour. Stir occasionally to prevent sticking. The chutney should thicken, and the liquid will gradually reduce.
- Once the chutney has thickened to a jam-like consistency, remove it from the heat. Allow it to cool slightly before transferring the mixture into sterilised jars.
- While you can eat the chutney once it has cooled, for the best flavour, let it mature in the jars for about a month.
Recipe Notes
- Ensure that you cook the onions slowly over a low heat for maximum flavour development. This caramelisation step is crucial for achieving the rich, sweet, and tangy flavour of the chutney.
- Stir frequently during the simmering phase to prevent the sugar from sticking to the bottom of the pan and burning, which can ruin the chutney’s taste.
- Unopened jars of chutney can be stored for up to 6-12 months in a cool, dark place. After opening, refrigerate and use within 4-6 weeks for the best flavour and freshness.

I found this too vinegary… experienced cook and followed the recipe exactly. Have added some water and put a lid on to break it down. See how it goes…
Hi Sophie, sometimes chutney will have a strong vinegary taste when used straight from cooking. If you give it some time to mature and mellow (about 1 to 3 months stored in sterilised jars in a dark place) it should mellow out. If you want a fix straight away, you can add a little more sugar or neutralise the acid with some bicarbonate of soda (just a little pinch added). However, providing the chutney has been cooked for long enough and isn’t to liquid, just allowing the chutney to mature should work just fine.
