Slow Cooker Cheesy Potato Broccoli Soup – easy soup cooked in the crockpot. It starts with frozen hash browns and frozen broccoli so there’s almost no prep involved! A kid favorite during fall and winter!

Slow cooker soup recipes are just the best during fall and winter. There’s nothing better than knowing you’re coming home to a hot bowl of soup after a chilly day.
This vegetarian Slow Cooker Cheesy Potato Broccoli Soup takes only about 15 minutes of prep in the morning (if that!) and is always a hit in my house.
Plus, I love that it calls for frozen hash browns and frozen broccoli so it’s really easy to have all the ingredients on hand at all times.
I usually make it with some homemade bread, like these Honey Yeast Rolls to soak up the last little bits of soup.
