Few kitchen moments feel as deflating as tasting a pot of soup you’ve been patiently simmering, only to realize you went a little heavy on the salt. What was meant to be warm, soothing, and comforting suddenly turns sharp and nearly impossible to enjoy. The good news is that a salty soup doesn’t have to end up in the bin. There’s a classic fix that’s practical, simple, and surprisingly effective.
When it comes to rescuing everyday cooking mishaps, Julia Child is often the name people return to for steady, common-sense guidance. One tip linked to her has become a go-to for this exact situation, and it’s been shared widely, including by Taste of Home. Instead of trying to mask saltiness with extra seasoning or diluting the whole pot until it loses its character, the idea is to remove the excess salt directly. The secret ingredient is something many kitchens already have.
The trick is to grate a raw potato and add it straight into the hot soup. Let it simmer gently for a few minutes so the potato has time to do its work. As it softens, it draws in liquid along with some of the dissolved salt, helping take the edge off that overpowering flavor. Once the soup tastes more balanced, strain out the potato, and you’ll be left with a pot that’s far closer to what you intended.
This works because raw, grated potato behaves a bit like a sponge in warm liquid. It absorbs moisture as it cooks, and with that moisture comes some of the salt that made the soup taste harsh. It’s a straightforward, old-school solution that relies on physical absorption rather than trying to “cover up” the problem with sweetness, fat, or extra aromatics. It also has a comforting simplicity, the kind of quiet kitchen magic that feels almost too easy when you’re stressed about ruining dinner.
One thing to keep in mind is that the potato can soak up some of the broth as well, which may slightly thicken the soup or reduce the volume. If that happens, simply add a splash of water, stock, milk, or cream, depending on the style of soup you’re making, and adjust until the texture feels right again. The goal isn’t to change your soup into something else, just to nudge it back into balance. And if you’re worried about anyone noticing, this is the kind of fix that quietly saves the day without announcing itself.
