Roasted Celery and Potato Soup | Tried and True Recipes (1)

Storytime! The first time I made this soup is when I was a teen. It’s my dad’s recipe, and he told me “JUST ONE CUP OF ELBOWS” before he left for work, but me being the carb monster that I am, decided that he was wrong and added the whole box. And that’s how I’ll never live down the cement soup tragedy where we couldn’t even get the spoon out of the pot.

This vegan version is much better than my first attempt 20 years ago! Usually, my dad would make it with potatoes, mushrooms, heavy cream, and elbows. To get big flavor plus creaminess without the dairy, I roasted celery first and then blended it with potatoes and some of the soup liquid and added it back to the soup. The finished product was SO good, and it’s such a great, cheap vegan soup recipe to throw together. If you aren’t vegan or dairy-free, you can certainly add a few splashes of cream at the end of cooking!

    FAQs

    Do you cook celery before adding to soup? ›

    What does celery do to soups? ›

    Celery stalks often play a supporting (albeit crucial) role in comforting soups and holiday sides, but their sharp herbal flavor takes center stage in this cream of celery soup recipe.

    Why isn't my potato soup creamy? ›

    Does sour cream thicken soup? ›
