Easy slow cooker cauliflower and potato soup recipe from @bakedbyrachel

I may not be the biggest fan of winter, but I sure do love soup season and with that, slow cooker season. But to be completely honest, I don’t think slow cookers really have a season. They should be used and enjoyed year round. They just happen to be used mostly in the colder months and with good reason!

A long day at work or shoveling the driveway, what better way to return home than to a warm meal, read and waiting for you. From soup and stews to pasta, shredded meat and so much more… even dessert – the possibilities seem nearly endless when it comes to slow cooker recipes.

I recently had the chance to review the new America’s Test Kitchen cookbook: The Healthy Slow Cooker Revolution. I dove right in and couldn’t take my eyes off of all of the drool worthy recipes and photos! Plus, there are so many awesome tips and tricks included throughout the cookbook. It’s a must have for any fan of slow cooker recipes!

The cookbook features healthy dinners… and sweets, pared down for smaller meals and in a quicker times!

Sticking with my new cookbook (and magazine) tradition…I flipped through and tagged all of the recipes of interest. Tell me I’m not the only one that does that? Stick notes, dog-eared pages, etc.

There are so many great ideas to choose from. I was *this* close to trying my first slow cooker dessert, but I couldn’t resist another delicious soup, especially being the dead of winter. It was clearly hard to decide which recipe to start with. Until the last moment before going to the store, I had no idea what I was going to pick, but I did have it narrowed down to a few. But then, I spotted the cauliflower. Decision made!

You’ll likely have the same problem! So many tasty options, but which to start with?!

I highly recommend starting with the cauliflower and potato soup! A creamy vegetarian soup that is full of flavor and easy to make! Cauliflower florets and golden potatoes blend together to create the perfect creamy cold weather comfort food! It’s an absolute must try!
