Never have I ever met a vegetable I haven’t liked… except for celery. I sometimes feel like celery is a useless vegetable. Don’t hate email me, please?!?!

It is made up mostly of water and has these strands that get stuck in your teeth. I would just rather skip it in recipes.

Don’t get me wrong, I do like celery as an excellent vehicle for transporting ranch or blue cheese into my face.

There are supposedly a lot of trendy health benefits to raw celery juice.

I haven’t been able to stomach or actually to make time to create my own celery juice in the morning.

I figured since sooooo many popular influencers out there are all on the celery bandwagon, I would give this lowly vegetable a shot.

Celery is the star of this soup. Slow cooker celery soup is a tasty vegetarian, dairy-free, creamy, and super easy soup. 

Cut and clean a whole bunch of celery, toss it into a slow cooker along with some peeled potatoes, diced onion, and garlic. Cover it with some vegetable stock, a little, salt, celery salt, and pepper. 

Set your slow cooker and walk away.

Use the blender or an immersion blender to puree the soup to your desired thickness.

I love to eat this soup with a little drizzle of a good olive oil on top and a whole slew of crunchy croutons.

This is how I can handle celery as the main event of a meal.
