Put your slow cooker to work to cook onions! All you need is onions, a little butter, a slow cooker and some hands-off time. Caramelizing onions in a slow cooker is the best way to get golden, buttery onions. A few years ago I read that you can cook onions down in a slow cooker.
Do you have to pre cook onions for slow cooker?
Cut down your prep time It can be nice to cook the onions beforehand, as the flavour is different to when you put them in raw, but experiment both ways as you may find you prefer one. It can also be good to brown meat to give it some colour, but again, this is not essential.
Can onions go in slow cooker?
Add onions to the bowl of your slow cooker. Drizzle the melted butter evenly over the top of them, then toss with a spoon (or with your hands) until the onions are evenly coated in the butter. Cook on low for 8-10 hours, stirring once or twice if desired, until the onions are a rich golden brown and caramelized.
