Ingredients for Easy 4-Ingredient Potato Soup
Main Ingredients
- Potatoes (russet potatoes work best)
- Onion
- Butter
- Milk or heavy cream
That’s it. Simple ingredients, big comfort.
Ingredient Notes & Substitutions
- Potatoes: Russet potatoes create the creamiest texture, but Yukon gold potatoes also work well.
- Milk vs. Heavy Cream:
- Heavy cream = richer, creamier soup
- Whole milk or 2% milk = lighter but still comforting
- Butter Substitute: Olive oil or plant-based butter can be used for a dairy-free option.
- Dairy-Free Option: Use unsweetened oat milk or almond milk for a family-safe alternative, understanding the soup will be slightly thinner.
Seasoning such as salt and pepper is added to taste and doesn’t count toward the main four ingredients.
Step-by-Step Instructions
Step 1: Sauté the Onion
In a large pot, melt half of the butter over medium heat. Add the diced onion and sauté for 3–4 minutes until soft and fragrant.
Step 2: Cook the Potatoes
Add the diced potatoes to the pot and cover with water. Bring to a boil, then reduce heat and simmer for 15–20 minutes, or until the potatoes are fork-tender.
Step 3: Drain and Combine
Carefully drain most of the cooking water, leaving about ½ inch of liquid in the pot. Add the remaining butter and milk (or cream).
Step 4: Mash or Blend
Use a potato masher for a chunky texture, or an immersion blender if you prefer a smooth, creamy soup.
Step 5: Simmer and Season
Let the soup simmer for 5 more minutes. Season with salt and pepper to taste, stir well, and serve warm.
Pro Tips for Success
- Cut potatoes into even-sized cubes so they cook evenly
- Don’t fully drain the cooking water—it helps create a creamy texture
- Mash gradually to control thickness
- Add milk slowly to avoid thinning the soup too much
- Taste before serving and adjust seasoning as needed
Flavor Variations
Want to change it up without losing simplicity? Try one of these ideas:
- Cheesy Potato Soup: Stir in shredded cheddar cheese at the end
- Garlic Lover’s Version: Add minced garlic with the onions
- Herbed Soup: Sprinkle in dried thyme or parsley
- Loaded Potato Style: Top with cheese, green onions, and turkey bacon
- Vegetable Boost: Add cooked carrots or cauliflower before blending
