My grandpa swore by this rich depression era staple. Takes exactly 3 ingredients to make a deeply flavorful meal that fills you up.
Variations & Tips
If you’d like to stay true to the three-ingredient spirit while nudging the flavor a bit, you can switch the type of broth: chicken broth will make a gentler, lighter soup, while vegetable broth keeps it meatless but still hearty. For a slightly thicker, creamier texture without adding new ingredients, use a potato masher to gently crush some of the cooked potatoes right in the slow cooker; this will release more starch and give the broth a velvety feel.
If your onions are very sharp, you can slice them a little thicker so they hold up longer and turn mellow and sweet as they cook. To stretch the soup for more people, simply add another potato and a bit more broth, keeping the same basic balance. Leftovers keep well in the refrigerator for a few days and actually deepen in flavor; reheat gently on the stove or in the slow cooker with a splash of water or broth if it’s become too thick.
