How to Make Slow Cooker Onion and Potato Soup
Start by preparing your vegetables. Peel and chop the potatoes into chunks, and slice the onions into thin strips.
Place everything into your slow cooker: potatoes first, then onions, and pour the broth over the top. Give it a gentle stir to distribute the ingredients evenly.
Cover and cook on low for 6–8 hours or on high for 3–4 hours. As it cooks, your kitchen will fill with a rich, savory aroma that hints at the comfort waiting inside.
Once the vegetables are completely tender, use an immersion blender to blend the soup until smooth. If you prefer a chunkier texture, blend only part of the soup or mash it lightly with a potato masher.
Taste and adjust if needed—while the recipe is minimalist, a pinch of salt and pepper can enhance the natural flavors even more.
Serving Suggestions
Serve the soup hot, straight from the slow cooker. It pairs beautifully with crusty bread, toast, or even a simple side salad.
If you want to dress it up a bit, consider adding toppings like shredded cheese, chopped green onions, crispy bacon bits, or a dollop of sour cream. But even on its own, the soup stands strong—simple, rustic, and comforting.
Tips for the Best Results
Choose starchy potatoes like Russets for a creamier texture, or Yukon Golds for a slightly buttery flavor.
Slice the onions thinly so they melt into the soup as they cook.
For a richer taste, you can swap part of the broth for milk or add a small pat of butter before blending.
