How to Make Old Fashioned Potato Soup Step by Step
Old fashioned potato soup is all about letting simple ingredients do the work. Start by melting butter in a large pot over medium heat. Butter was traditionally used because it adds richness without overpowering the potatoes. Add the finely chopped onion and cook slowly until it turns soft and translucent. Avoid browning—it should melt into the soup rather than stand out.
Next, add the diced potatoes, water, salt, and black pepper. Unlike modern recipes that rely on broth or cream bases, traditional versions often used water and allowed the potatoes themselves to create flavor and body. Bring the pot to a gentle boil, then reduce the heat to a low simmer. This slow cooking is essential. As the potatoes soften, they begin to break down naturally, thickening the soup without any flour or cornstarch.
After about 25 to 30 minutes, the potatoes should be very tender. Use a spoon or potato masher to lightly mash some of them directly in the pot. This creates the signature thick, rustic texture that defines old fashioned potato soup. Stir in the milk and keep the heat low, allowing everything to warm through without boiling. Taste and adjust seasoning if needed.
Let the soup rest for a few minutes before serving. It will continue to thicken as it sits, becoming even more comforting and hearty.
Conclusion
Old fashioned potato soup is proof that timeless recipes endure for a reason. Built on simple ingredients and slow cooking, it delivers warmth, nourishment, and a sense of home in every bowl. There are no shortcuts here—just honest food made the way it always was. When you want a meal that feels grounding, familiar, and deeply comforting, old fashioned potato soup is always the right answer.
