WW Recipe of the Day: Slow Cooker Caramelized Onions
The inspiration for these delicious slow cooker caramelized onions comes from the Cafe Zupas cookbook.

Are you familiar with Cafe Zupas?
You may not be because they only have locations in Utah, Arizona, Idaho, Illinois, Minnesota, Ohio, Wisconsin and Nevada right now.
I’m lucky to live only a few miles from their Phoenix location.
I fell in love with their house made soups, salads, sandwiches and desserts after my friend, Beth, turned me on to them.
So, needless to say I was thrilled when a copy of their Blogger’s Annual Cookbook with a gift card showed up in my mailbox recently ๐

A collection of the best fresh and delicious recipes from Cafe Zupa’s bloggers, organized by season, I identified all kinds of recipes I can’t wait to try.
Recipe’s I’ve tagged include:
- Honey Lemon Pound Cake with Fresh Strawberries
- Greek Pasta Salad
- A Better Tin Foil Dinner
- Roasted Butternut Squash Salad
But right now I was focused on finding a recipe I could make work in the slow cooker and found exactly what I was looking for on page 54 – Caramelized Onions – which are best when cooked low and slow.
Recipe Notes
I’ve been know to burn onions when trying to caramelize them on the stove.
But, it’s really hard to overcook onions in the slow cooker.

I cooked a large batch in my 6-Quart slow cooker (affiliate link) overnight.
In the morning I cooked them a little longer with the lid ajar, allowing most of the liquid to evaporate.
So far I’ve used these sweet, delicious low fat slow cooker caramelized onions on a ham and Swiss cheese flatbread and with grilled asparagus, mushrooms and pesto in a wrap.
They’re a great way to add delicious flavor with minimal calories and points. And are Weight Watchers Simply Filling too.

- Cover and cook on LOW for about 10 hours. If possible, you can stir them occasionally, but this is totally optional. If you like deeper colored onions, cook 2 to 4 hours more with the lid ajar to let the excess moisture escape. Check them every hour or so until they have reached they have the color and taste that seems good to you.

This looks yummy – and this restaurant looks FAB!! They must put one in northern Nevada – dang Vegas gets everything!!! I’d be their biggest fan with those salads!
Will this cookbook be available to everyone? Where can one buy it?
Hi Beth,
I’m not sure about the book’s availability. It’s not on Amazon. I’ll check out the Zupa’s website to see if I can learn anything for you.
