This red onion chutney has really cheered up my meals recently. And did I tell you I hate dry food? Usually if there's sauce or gravy going, I'm all over it. That's probably the Northerness in me (which always need a capital N).
I love a good relish or chutney that I can spread on my bacon sarnies, eat with meat and sometimes a dollop in the centre of my soup. And knowing this is syn free is truly a relaxing thought.
(Oh and omelettes. I don't say no to sauce on that either, or a sweet chilli sauce which I'll talk to you about very soon!
And the beauty of this one is it's syn free. Ok, the french baguette isn't so much, but I was so proud of this recipe, there's something about a wholemeal roll that isn't as photogenic, so please forgive me.
(Let's say I enjoyed the cheeky syns on your behalf). And once cooking session gives me two and a half jars left to keep me going for a while. Lovely stuff.
The other great news is that it was so easy made in my slow cooker. However, if you don't have gone, why not try simmering for around 40 minutes.
And probably a word of warning about any chutney. It will stink your house out with a sweet vinegar aroma. It's a bit eye stingy to start off with but you want to cook off the sharp tang.
Once it's toned down, you're good to jar it up and store in the fridge, maybe for two months at the most. Sadly I don't think I'll ever know as I go through sauces pretty quick.
Makes an average of 82 tablespoon which is just under 1 counted calorie. You would need to eat 20.5 tablespoons to make up 1 syn.
📖 Recipe

Sugar Free Slow Cooker Red Onion Chutney/Pickle
Ingredients
- 1 kg red onions halved & thinly sliced
- 2 garlic cloves minced
- 8 tablespoon granulated sweetener
- 200ml balsamic vinegar
- 150ml apple cider vinegar
- 150ml malt vinegar
Instructions
- Place everything in the slow cooker and place a sheet of tin foil on top before placing on the slow cooker's lid.
- Cook on high for 5-6 hours without stirring. If it's too vinegary, cook it for longer until it's toned down to your liking.
- Spoon in to sterilised jars while hot and screw the lid in to place and place in the fridge. I personally think mine might last 2-3 months from the vinegar's acidity but will keep you posted.
- If you made it and loved it, why not tag me on Instagram with a pic using @TastefullyVikkie?

How long would you leave it if it was on a low heat?
Michala
Could you cook this on a low setting on the slow cooker as I’m rarely in the house so would need to cook it longer eg while im at work. Any advice on times gratefully received ?
Helen
Hey Vikkie,
Love onion chutney so so much. I'd love to try it but I don't have a slow-cooker.
Do you think it's possible to make it in a pot? If so, high heat or low heat? Thank you.
Gail
Trying this out.. presently in the slow cooker. How long did it last for Vikkie as am hoping to give out to family along with other chutneys nearer Christmas time.
vikkie
I still have a jar in my fridge and it's still perfect! Same goes for my sweet chilli sauce too! 🙂
Shirl
I might try this with carrots because I love Carrot chutney
vikkie
I think leaving it to cool, the onions might soak up some of the moisture. Mine went dryer when jarring. Hope that helps

I really can’t stand artificial sweeteners, would it work without it? I know onions are pretty sweet when caramelised anyway
