Crock Pot Caramelized Onions

Total Time

Make up a bunch of caramelized onions at once and freeze them for later. This is so easy.


  1. You can use just about any kind of onion for this--Vidalia, Spanish, yellow--it's your choice.
  2. Slice the stem and root ends off each onion. Peel the onions, but leave them whole.
  3. Place onions and butter in crock pot and cook on low for anywhere from 12-36 hours. The onions will get deep golden brown and literally fall apart.
  4. Use right away or freeze for later.
  5. Suggested uses: in omelets, sandwiches, soups, casseroles, dips, pasta sauce, or alongside any grilled meat.
  6. Note: If your crock pot is big enough, you can double the amount of onions.

Great recipe! Great way to use up the last of the 10# bag of onions I buy from Costco. I used these broken up on pizzas and in casseroles. I cannot wait until the sweet Vidalia and 1015s come back into season. I am going to freeze lots of these.

DH loves onions but I have to saute them first to mellow them as they love him back all night after he eats them. This was a great idea. I froze the onions after caramelizing and used them as needed for various dishes. They smell great while cooking,too. Thanks, Jeri.

These are so simple and so good. I did them overnight, and they smelled so good when I hit the kitchen in the morning. Not sure caramelized onions go with coffee, but they sure smelled great. Thanks for a good and easy recipe, JeriBinNC.
