The Only 4 Ingredients You Need

This recipe relies on everyday ingredients that work together to create a creamy, hearty soup.

Ingredients

4 large potatoes, peeled and diced
1 medium onion, finely chopped
4 cups milk (whole milk for best creaminess)
Salt, to taste

That's it—no fillers, no complicated seasoning list, and no specialty items.

Step-by-Step Cooking Instructions

1. Prepare the Potatoes

Peel and dice the potatoes into evenly sized cubes. This ensures they cook evenly and break down smoothly during simmering.

2. Simmer the Base

Add the diced potatoes and chopped onion to a large pot. Pour in the milk until everything is just covered. Cook over medium heat, stirring occasionally to prevent sticking.

3. Cook Until Tender

Let the mixture gently simmer for 20–25 minutes, or until the potatoes are very soft and easily mashed with a spoon.

4. Mash or Blend

For a chunky texture, lightly mash the potatoes directly in the pot. For a smoother consistency, blend until creamy using a hand blender. Season with salt to taste.

Texture and Flavor Tips

Thicker soup: Mash more potatoes or simmer a few minutes longer
Thinner soup: Add a splash of milk and stir gently
Extra creamy feel: Use whole milk or a mix of milk and cream

Despite having just four ingredients, this soup delivers a naturally rich flavor thanks to the starch from the potatoes and the sweetness of the onion.

Optional Add-Ons (Without Changing the Base Recipe)

While the core recipe stays true to four ingredients, you can enhance it when serving:

Fresh cracked black pepper
Chopped green onions or chives
A small pat of butter stirred in before serving
Crispy bacon or shredded cheese as a topping

These additions allow customization without complicating the cooking process.

How to Serve This Simple Potato Soup

This soup works well as:

A comforting main dish with warm bread
A light lunch or dinner option
A starter for a larger meal

Serve it hot, straight from the pot, for the best flavor and texture.

Storage and Reheating

Refrigeration: Store in an airtight container for up to 3 days
Reheating: Warm slowly on the stovetop, stirring often
Consistency tip: Add a little milk when reheating if it thickens
