Slow Cooker Caramelized Onions turn out perfectly in the slow cooker and can be used for so many things such as soups, pastas and on top of burgers.

Several weeks ago I was able to spend a few days at The J.M. Smucker’s headquarters in Orville, Ohio. I learned lots about the company, met lots of fun bloggers and ate a lot of yummy food. Tomorrow I’ll have a a full post all about my trip but today I wanted to share with you one of the recipes they shared with us in the Make Ahead Meals presentation we had.

I think this may have been my favorite idea they shared with us!!

They showed us how to caramelize onions in a slow cooker. I love caramelized onions but what I don’t like is chopping onions. My husband is the official onion chopper at our house.

How to make slow cooker Caramelized Onions

It’s so easy to make a big batch of caramelized onions. You can make a whole batch all at once and then freeze them to use later on lots of yummy things. Just get your husband to slice up the onions and then put them into your slow cooker. Add in some olive oil and salt and then put the lid on and cook on slow all day. Cook them until they get the desired brownness and caramelized just how you like them. I cooked mine for 10 hours on low.

Over the next few weeks I’ll be sharing a few recipes using caramelized onions but I am not opposed to just digging in with a fork and eating them all by themselves. They are also a great topping for a burger or add to some homemade pizza. Throw them in your favorite soup or top some veggies with them. So many possibilities.

Can I Freeze Caramelized Onions?

They freeze great. I placed them in about 1 cup serving size into a freezer bag. Squeeze out as much air as you can and place in the freezer.

Just pull them out when you need them.

How Do I Use Caramelized Onions?

They can be added into soup, pasta sauces, on veggies or on top of a burger.

Here are some recipes we love using them in:
