Here’s a very simple slow cooker 3-ingredient onion and potato soup—minimal effort, hearty, and naturally creamy without needing many extras.
🧅🥔 Slow Cooker 3-Ingredient Onion & Potato Soup
🧾 Ingredients
- 4–5 large Onion (sliced)
- 5–6 medium Potato (peeled and diced)
- 4 cups vegetable or chicken broth (or water + salt)
That’s it—just three core ingredients.
👨🍳 Instructions
1. Prep the vegetables
- Slice onions thinly (they’ll melt into sweetness during cooking)
- Dice potatoes into small cubes for faster, even cooking
2. Add to slow cooker
- Put onions and potatoes into the slow cooker
- Pour in broth until everything is just covered
- Stir lightly
3. Cook
- Low: 6–8 hours
- High: 3–4 hours
You’ll know it’s ready when:
- Potatoes are soft
- Onions are completely tender and almost dissolved into the broth
4. Blend (optional but recommended)
- For a creamy soup: use a blender or immersion blender
- Blend until smooth or leave slightly chunky if you prefer texture
🍽️ Serving ideas (optional extras)
Even though it’s a 3-ingredient base, you can upgrade it easily:
- Black pepper for warmth
- A drizzle of olive oil or butter for richness
- A pinch of salt (important if your broth is low sodium)
- Fresh herbs like parsley or thyme
💡 Tips
- Yellow onions give the sweetest flavor after slow cooking
- Russet or starchy potatoes make the soup naturally creamier
- If it tastes “flat,” it usually just needs salt or a bit of fat
If you want, I can turn this into a restaurant-style creamy version, a low-calorie weight-loss version, or a high-protein version.
