Ingredients & Method
Ingredient Breakdown
| Ingredient | Purpose / Note |
|---|---|
| 4–5 medium potatoes, peeled & diced | Main body and texture |
| 1 medium onion, chopped | Flavor base |
| 2 tablespoons butter | Fat and richness |
| 4 cups broth (vegetable or light chicken) | Liquid base |
| 1 cup milk (dairy or plant) | Creaminess without fuss |
Step‑by‑Step Instructions

- In a large pot, melt the butter over medium heat. Add chopped onion and cook until soft, about 3–4 minutes.
- Add the diced potatoes to the pot, then pour in the broth until it covers the potatoes by about an inch.
- Bring to a boil, then reduce heat and simmer for 12–15 minutes or until potatoes are tender.
- Use an immersion blender (or transfer in batches to a blender) to puree until mostly smooth, leaving some texture if you like.
- Stir in milk gently, warming on low heat—do not boil.
- Season with salt and pepper to taste, ladle into bowls, and if you have it, top with a pat of butter or fresh herbs.

Variants & Smart Tweaks
Flavor Boosters & Add‑Ins
- A dash of smoked paprika or cayenne for heat.
- Stir in chopped cooked bacon or sausage (if available).
- Use half‑and‑half instead of milk for more creaminess.
- Top with chopped green onion or chives for freshness.
Adjusting Thickness & Texture
- For a thicker soup, reduce broth or blend more.
- For a thinner version, add extra broth or milk.
- Avoid boiling after adding milk — cook gently to prevent separation.
- Warm the milk slightly before stirring it in to reduce temperature shock.
Frequently Asked Questions (FAQ)
Q: Can I make this ahead?
Yes — let the soup cool, store airtight in the fridge up to 3 days. Reheat slowly on the stove, adding extra milk or broth to loosen as needed.
Q: Can I freeze this version?
You can, but some separation may occur because of the milk. Thaw in the fridge and reheat gently, whisking to recombine.
Q: What if I don’t have an immersion blender?
You can transfer half the soup to a stand blender, puree, then stir it back in to keep texture.
Q: Can I use a non‑dairy milk?
Yes — unsweetened oat, cashew, or soy milk work best. Avoid watery varieties like almond milk if you want good texture.
