Slow Cooker 3-Ingredient Onion and Potato Soup

1. Layer in Slow Cooker

Place potatoes and onions in the slow cooker.
Pour broth over top.
Add optional butter/oil, thyme, or bay leaf if using.

2. Cook Low & Slow

Cover and cook on LOW for 6–7 hours (or HIGH for 3.5–4 hours), until potatoes are very tender and onions have dissolved into the broth.

3. Finish to Perfection

Remove bay leaf or thyme stems.
For smooth soup: Use an immersion blender to purée until creamy (or blend ½ in a countertop blender).
For rustic texture: Mash lightly with a potato masher.
Season with salt and pepper to taste.
