How To Caramelize Onions in the Slow Cooker

These are so good and versatile.
Cooking Instructions
- 1
Peel and thinly slice all of the onions into half moons. Transfer all the onions to the slow cooker — the slow cooker should be half to three-quarters full.
- 2
Drizzle the olive oil or melted butter and the salt, if using, over the top of the onions. Toss to evenly coat all the onions with a thin glaze of oil.
- 3
Cover the slow cooker and cook for 10 hours on LOW. If you're around while the onions are cooking, stir them occasionally — this will help them cook more evenly, but isn't strictly necessary.
- 4
After 10 hours, the onions will be golden-brown and soft, and they will have released a lot of liquid. If you like them as they are now, stop cooking and pack them up.
- 5
Optional — cook an additional 3 to 5 hours with the lid ajar: If you'd like jammier, more concentrated onions with a deeper color, continue cooking for another 3 to 5 hours on LOW. Leave the lid ajar so the liquid can evaporate. Check every hour and stop cooking whenever the onions look and taste good to you.
- 6
Remove the onions with a slotted spoon and transfer them to refrigerator or freezer containers. If any liquid remains in the slow cooker, transfer the liquid to a separate container — this can be used as cooking broth in another recipe. Onions will keep in the refrigerator for one week or in the freezer for at least 3 months.
