Whatever you do, once you add your thickener, turn down the heat. Simmering too long can break down the starch and make your soup thin again. It’s like a yo-yo diet for your dinner—no one wants that.
Also, taste as you go. Add salt and pepper, because thick soup that tastes like cardboard is just sad pudding. If you’ve gone too far and your soup is now paste, add a splash of broth or milk to rescue it.
So relax. Your potato soup isn’t doomed—it’s just asking for a little love. Whether you mash, slurry, or cheese-bomb it, you’ll end up with something that hugs you from the inside. Now go forth and thicken.
