Slow Cooker Sweet Potato and Celery Soup


Happy Thursday Melrose Family readers! Justine from Cooking and Beer here to share with you one of my favorite ultimate comfort foods: Slow Cooker Sweet Potato and Celery Soup with Barley! I hate to be that person. The person that REMINDS you that summer is coming to an end. I mean the kids here in Wyoming have already gone back to school! I’m definitely not ready for summer to end. All of that fresh delicious local produce and warm nights on the deck with a drink will become a thing of the past. It makes me super sad.

One thing I do get super excited about once autumn rolls around is the food. While I love the freshness of summer dishes, I love the comfort that comes from a warming dish on a cool day. Soups and slow cooker meals are at the top of that list, and this slow cooker sweet potato and celery soup with barley combines the two of them! Two-in-one perfection is what this soup is. Trust me.

I think a common misconception about comfort food is that it’s fattening and full of all that deliciousness you don’t want to speak of the next day. You know what I’m talking about. The cream. The cheese. I could go on..and on…and on. This sweet potato and celery soup is comforting, but it’s also a healthy kind of comfort food. Loaded with veggies, this soup is what you need to keep yourself healthy through the fall and winter months.

In addition to this soup being vegetarian and ultra good-for-you, it’s also soooooo easy to make too! Sweet yellow onion, celery and garlic are cooked until tender in a hot skillet. After the veggies have been transferred to the bowl of your slow cooker, sweet potato, barley and other essential soup ingredients are added along with them. Slow cooked on high for about 4 hours, the result is pure healthy, vegetarian comfort food in a bowl. Garnish with fresh avocado, carrots and parsley for added flavor and texture! I really hope you guys love this recipe. It’s one of my favorites!
