Caramelized onion and cream cheese dip

Dip / spread+ Vegetable / fruit recipe by Connie Veneracion | Last updated: 12.02.2025
Imagine French onion soup as a dip. Thick, creamy and absolutely tasty. It takes about 12 hours to make it in the slow cooker, but there’s very little work involved. It’s patience that’s required and it will be amply rewarded.

Cook’s notes

My husband’s work, perfected. He has made this caramelized onion and cheese dip at least three times in search of perfection. And he did it on the third attempt. Neighbors who have tried it encourage him to sell it in small tubs but he wants to make it only for family and friends.
Why use a slow cooker? It takes a long time for the onions to soften and caramelize. If you do this on the stovetop, you will need to stir the onions often to make sure they don’t scorch. Who wants to hover over the stove for an hour or longer to cook onions? Softening them in the slow cooker is the smarter choice.
Sweet mildly flavored onions are best for making this dip. In my part of the world that means large yellow onions.
Consume the dip within three to four days.
