What is Butter Potato?
Butter Potato is a popular Korean snack commonly found at highway rest stops. On Korean menus, it’s usually listed as “Al Gamja” (baby potatoes) or “Tong Gamja” (whole potatoes). This dish features small, whole potatoes that are roasted in butter until they are golden and flavorful. They are loved for their rich, nutty taste and satisfying texture.
You won’t find buttery potatoes in restaurants or cafés. They’re a unique snack that you can only get at Korean rest stops. They’re a must-try during any road trip in Korea!
What Does Butter Potato Mean to Koreans?
To many Koreans, butter potato is more than just a snack; it’s tied to childhood memories of long road trips with family.
During major holidays like Chuseok or Lunar New Year, Korea’s highways used to become extremely congested. While roads have improved and fewer people travel back to their hometowns nowadays, it used to be common to drive over 10 hours to visit family. Along the way, families would stop at rest areas (or gas station) to rest, eat, and stretch. That’s how snacks like Butter Potato became part of the journey. For many, the taste of Butter Potato is nostalgic and brings back memories of time spent with loved ones.
I still remember how my parents would buy me the Butter Potatoes whenever we stopped at a rest area. Even now, I sometimes go out of my way to buy them just to experience that comforting, familiar taste from my childhood again.
Ingredients
- Potatoes: Traditionally, al-gamja (baby potatoes) are used, but you can also cut larger potatoes into chunks if that’s what you have.
- Butter: The key ingredient — the potatoes are coated and cooked in butter, giving them a rich, nutty flavor.
- Sugar & Salt: Korean snacks often combine sweet and salty flavors — we even have a word for it: “dan-jjan” (단짠). At rest stops, the potatoes are usually simply salted, and you can sprinkle extra sugar or salt to taste. But today, I’ll be caramelizing them in both sugar and salt for the ultimate flavor.
Butter Potato Recipe
The original Buttery Potatoes are grilled on large metal pans at rest stops until crispy and golden.
But today, I’m making a simpler home version using a frying pan, inspired by the Korean food show “Pyeon-storant” and celebrity chef and actor Ryu Sooyoung’s recipe.
This version features a delicious caramelized glaze made with butter and sugar, creating that irresistible crispy coating. Trust me. It’s seriously good!
The Debate: Sugar or Salt?
When you order butter potatoes at a Korean rest stop, you’ll receive plain, buttered potatoes. It’s up to you to sprinkle sugar or salt on top!
This has sparked a fun — and very serious — debate among Koreans, similar to the infamous “pour or dip” argument for sweet and sour pork (Tangsuyuk). Everyone has their preference. So, if you’re traveling with a Korean friend, be sure to ask, “Team sugar or team salt?” before sprinkling. You don’t want to start a snack war!
