Slow Cooker Caramelized Onions

Wow. Slow cooker caramelized onions were so much better than I ever thought they could be. They were incredibly tasty. And perfect on grilled cheese sandwiches. And on burgers, in French onion dip or soup. Any recipe that calls for onions needs caramelized onions.

You might get thrown out of a fancy (or actually, even a not-so-fancy) restaurant kitchen if you suggested making slow cooker caramelized onions. But you won’t get thrown out of my kitchen. I’d make these again in a heartbeat. My favorite onions to use are Vidalia onions, but unfortunately they aren’t available for very long each year.

Try my blue cheese burgers with caramelized onions.
