This slow cooker version keeps things even simpler, using only three main ingredients while allowing time to build deep, natural flavor.
Why This Recipe Is So Good
This soup shows how powerful simple ingredients can be:
- Onions slowly soften and develop a natural sweetness
- Potatoes add thickness and a creamy texture
- Broth brings everything together into a savory base
With the slow cooker doing all the work, you get a rich, satisfying soup without much hands-on time.
Ingredients
You only need three essentials:
- 4 large onions (yellow or white), thinly sliced
- 4–5 medium potatoes, peeled and diced
- 4 cups vegetable or chicken broth
Optional for serving: salt, pepper, butter, cream, or fresh herbs
How to Make It
1. Prep the Vegetables
Slice the onions thinly so they cook evenly and release their sweetness.
Peel and dice the potatoes into similar-sized pieces for consistent cooking.
2. Layer in the Slow Cooker
Place the onions at the bottom of the slow cooker.
Add the potatoes on top, then pour in the broth until the vegetables are mostly covered.
3. Cook
Cover and set your slow cooker to:
- Low: 6–8 hours
- High: 3–4 hours
As it cooks, the onions become soft and flavorful, while the potatoes naturally thicken the soup.
4. Adjust the Texture
Once everything is tender, choose your preferred style:
- Chunky: Leave it as is for a rustic feel
- Smooth: Blend with an immersion blender or in batches until creamy
5. Finish and Season
Taste the soup and add salt and pepper if needed.
For extra richness, stir in a bit of butter or a splash of cream.
Serving Ideas
Enjoy the soup hot with:
- Crusty bread or toast
- Fresh herbs like parsley or chives
- A drizzle of olive oil or a small pat of butter
It also pairs nicely with a light salad for a balanced meal.
Tips for Best Results
- Use a flavorful broth—it makes a big difference
- Cooking on low heat gives the best depth of flavor
- Add extras like garlic, cheese, or crispy bacon if you want to enhance it
