Slow Cooker 3-Ingredient Onion and Potato Soup

 

This recipe is proof that comfort doesn’t need complexity. With just three humble ingredients, your slow cooker transforms potatoes and onions into a velvety, savory soup that tastes like it simmered all day. The onions melt into the broth, the potatoes release their natural starch, and together they create a creamy consistency—no flour or heavy cream required.

 

Perfect for chilly evenings, busy weeknights, or whenever you crave a nourishing bowl with minimal effort, this soup adapts to your preference: silky-smooth or rustic and chunky. Either way, it delivers warmth in every spoonful.
