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

    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. To coax the most flavor out of the veg, sauté the chopped celery with a potato and onion in plenty of butter until soft and tender.

    What Flavour does celery add to soup? ›

    Celery has a very distinctive flavour and I think it's one of those things you probably either like a lot or not at all. As part of a soffritto or in a large salad or vegetable mix, it remains more subtle, adding just a touch of sweetness, especially once cooked; raw there's a slight bitterness to it.

    What makes potato soup gritty? ›

    Waxy varieties are ideal for creating a smooth texture, while starchy varieties work better for creating a dish that's light and fluffy. Russet potatoes, as a member of the starchy/floury potato family, are inherently grainy. Using them in soup will result in an unpleasant gritty texture.

    Should celery be sauteed before adding to soup? ›

    While certain vegetables can work just fine added directly to simmering soups and stews (say, carrots and celery), other vegetables (onions, garlic, and the like) will almost always need at least a brief sweat in a fat-based liquid before adding the remaining ingredients.

    Why do you soak celery in water? ›

    Because of its high water content, celery is best stored wet. While there are some dry storage methods, storing celery in the refrigerator—either in a container of water or wrapped in a damp towel—ensures it will stay crispy and fresh for the longest amount of time.

    Can you put too much celery in soup? ›

    Celery, carrots, and any other additions are meant to enhance the taste of the chicken, adding depth and variety. However, too many vegetables may change the taste entirely, turning it into vegetable soup with a side of chicken. Don't use too many vegetables when making the soup -- three or four is the sweet spot.

    What is the key to flavorful soup? ›

    The basic principles of soup-er soups and stew-pendous stews

    All soups and stews must have three major components in order to be tasty: an undercurrent liquid, aromatics, and volumizing ingredients.

    Do you have to peel celery for soup? ›

    Celery does not need to be peeled. It naturally has a stringy, tough texture, so peeling does not make that much of a difference. However, you can certainly peel each rib if you want to remove some of the tough outer layer.

    What is the best thickening agent for potato soup? ›

    Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry.

    Why does my potato soup taste bland? ›

    Not Adding Acid. If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

    Why isn't my potato soup creamy? ›

    One trick to make your potato soup a little less grainy is to add some form of dairy –- cream, milk, or even cheese. Because dairy is generally creamy in texture, that characteristic will carry over into your soup. Crisis averted.

    Which potato is best for soup? ›

    Russets or all-purpose baking potatoes are high in starch and low in moisture. In soups, they will soak up the liquid and lose their shape. This makes them the ideal choice for making creamy soups or thickening a runny soup. Try using Russet potatoes to create the perfect Loaded Potato Soup.
