Ingredients & Substitutions
These are the main ingredients and substitutions for 4 ingredient potato soup. Scroll down to the recipe card for full ingredients list and instructions.
Chop onion finely. White onion and sweet onion are both great options. I do not recommend red onion.
Butter adds a great buttery flavor to this soup. In addition, it helps cook the onion. For dairy free, use dairy free butter. Olive oil would not produce the same creamy texture.
Russet potatoes are the best option for this soup. They become soft and tender once cooked. If desired, Yukon gold potatoes are another great option.
Any type of milk works. For Whole30 and Paleo, use dairy free milk. Use regular milk for nut free. For these photos, I used unsweetened almond milk.
Garlic powder adds a great slight garlic flavor! Feel free to add in a pinch of salt and pepper as well.
Lastly, add your favorite toppings. Crispy bacon, chopped green onions and shredded cheese are great options.
Taste & Texture
This 4 ingredient potato soup tastes like mashed potato in soup form! The toppings chosen will also add a strong flavor.
The texture is so creamy. I blended mine until smooth and creamy. For a thicker, chunkier soup, do not blend as long.
How to Make
First, add diced onion and 1 tablespoon butter to a large skillet over medium heat. Cook for 5 minutes or until onions are softened.
Remove onions to a plate. Add diced potatoes to skillet. Add enough water to cover potatoes.
Bring to a boil. Then, boil for 18 to 20 minutes or until potatoes are fork tender.
Drain out the majority of the water, keeping about ½ cup of water in the skillet. Add in the remaining 3 tablespoons butter, milk and garlic powder. Stir together.
Add all ingredients to a food processor. Next, pulse until desired consistency is reached.
Finally, ladle into bowls. If desired, garnish with crispy bacon, green onions and shredded cheese.
