Slow Cooker Caramelized Onions – sweet and buttery caramelized onions that are all done in your crockpot. They turn out perfectly every time, without standing over and stirring the whole time!
I love caramelized onions and use them in a LOT of different ways. But they can take forever to cook on the stove top, and can be so finicky to get just right. You can’t have them too hot, too low, stir just the right amount etc.
Making caramelized onions in the crockpot is very hands off, and they turn out perfectly every single time!

Yes, they actually freeze really well. So if you make a very large amount, you can divide them into smaller portions, what you would use for each recipe, and store in an airtight container or in a zip top plastic bag, so you can flatten to get the air out, in the freezer. Thaw in the fridge and then use as called for or desired in a recipe.
You want to use something that is labeled as a sweet onion. Vidalia onions are the most common and are delicious. But lots of stores will have a sweet yellow or white onion, you can use whatever is available.
Yes, I called for butter in the recipe, and often times when I make it on the stovetop I use a combination of both. So you can use whatever you like. You need about 4 Tablespoons for 3 large onions, so any combination up to that amount will work great.
Caramelized onions are great leftover. Just put them in an airtight container in the fridge for up to a week. You can warm them up in a skillet or just add them to the recipe as called for.

OMG! Thank you so much. I have been trying to caramelize onions forever and it never works. I either burn them or they are under cooked. I can't wait to try this method.

Absolutely! I like to put them in a freezer safe plastic bag, so I can press all the air out and store them flat. They will last for probably 5-6 months.
