Start by placing the thinly sliced onions in your slow cooker, then add the butter, brown sugar, and all-purpose seasoning blend.

Once your onions are richly browned and irresistibly fragrant, they are ready to enjoy. These caramelized beauties can be served right away, adding a burst of sweet-savory goodness to any dish you love. Congratulations, you’ve nailed the Crock-Pot Caramelized Onions Recipe!
