There’s something magical about a jar of homemade chutney. Sweet, tangy, and packed with rich caramelised onion flavour, this recipe is a kitchen staple you’ll want on hand year-round. Whether you’re spreading it on warm crusty bread, pairing it with cheese, or stirring it into dips (like hummus – one of my favourite hacks), this sweet onion chutney is simple to make and keeps beautifully.

And the best part? You don’t need fancy equipment – just a few basics, some pantry staples, and a little time. I first made this after a very productive year for onions in the garden and never looked back since! I’m constantly asked by friends and family ‘when can I expect another jar??’.

Instructions:

Step 1 – Prepare the onions
Peel and slice your onions thinly. The thinner the slices, the quicker they’ll soften and caramelise.

Step 2 – Slowly soften
In a large heavy-bottomed saucepan (affiliate link opportunity), cook the onions gently on low heat for 20–25 minutes until golden and caramelised. Stir occasionally to avoid catching.

Step 3 – Add the flavour
Add the garlic, wholegrain mustard, ginger, salt, and paprika. Stir through and cook for another 2–3 minutes until fragrant.

Step 4 – Sugar & vinegar magic
Tip in the sugar and vinegar, then stir until dissolved. Bring to a simmer, then reduce the heat and let it bubble gently for 40–50 minutes. Stir occasionally – you want it thick and glossy.

Step 5 – Pot it up
Spoon the chutney into sterilised jars (affiliate link for jars & funnel), seal, and leave to cool. It’s best left for a couple of weeks to mature, but you can eat it right away
