Slow Cooker Caramelized Onions
I love caramelized onions – as a topping for sandwiches, in soup, even in sauces (I puree them and it adds a special little something to gravies and sauces). They are great for making French onion soup – add broth and croutons and top with a little cheese.Unfortunately it takes time to cook them down properly, and I always seem to want them when I have the least amount of time to make them.The slow cooker turned out to be the perfect solution to my problem. I make them in batches and freeze them in small portions and then thaw them in the microwave when I want them. It’s a great way to use up onions if they are starting to turn soft.
Equipment
- Slow Cooker
Ingredients
- 2 Tbsp butter
- 5 large onions white or yellow, sliced into ¼ inch slices
Instructions
- Grease the inside of the slow cooker with about 2 tablespoons of butter.
- Separate the sliced onions into rings, and place in slow cooker. Don't fill it more than ¾ full.
- Set the slow cooker on low, and let the slow cooker do its magic. It takes about 8 hours, slightly less if you use fewer onions. Use a large spoon to stir the onions about every two hours.
Notes
You can store them in the refrigerator for up to three days, or freeze them in small portions for several months.
