Master the art of Naengsam. Learn why Korean frozen pork belly is a BBQ favorite and how to grill it for the perfect Maillard reaction.
1. Defining Naengsam: The Unique Features of Korean Frozen Pork Belly
Naengsam is not merely "pork that happened to be frozen." In the context of Korean BBQ, it refers to pork belly that is intentionally frozen to allow for precise, paper-thin slicing.
Korean BBQ (K-BBQ) has transcended its origins to become a global culinary phenomenon.
While premium thick-cut pork belly often takes the spotlight, there is a specific sub-culture dedicated to Naengdong Samgyeopsal, or "Naengsam" (frozen pork belly).
Once considered a nostalgic budget meal, it has evolved into a trendy aesthetic and flavor profile celebrated in urban food hubs from Seoul to Los Angeles.
"Naengsam" It is characterized by frozen pork belly and cutting it to make it easier to grill.
Unlike standard Samgyeopsal, which can be an inch thick, Naengsam is sliced thin—usually between 2mm to 3mm. The freezing process changes the cellular structure of the meat slightly, which, when combined with the thin cut, creates a distinct "crispy yet chewy" texture that thick cuts cannot replicate.
It is often served with foil. However, what is commonly used as a grill is more often used because it is not healthy.
As you can see in the picture, it's easy to understand if you look at a Korean barbecue with such thin pork
2. The Science of the Sizzle: How to Grill Naengsam Perfectly
To achieve the best flavor, one must understand the Maillard reaction—the chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor.
Because Naengsam is thin and high in fat, the window between "perfectly browned" and "burnt" is small.
- Managing the Fat: Pork belly is naturally high in fat. As the meat hits the heat, the fat renders out, essentially "shallow frying" the meat in its own oils. This results in a crunchy exterior.
- Achieving the Maillard Reaction: Do not flip the meat too early. Wait for the edges to curl and the surface to develop a deep golden-brown crust. This is where the umami flavor is concentrated.
- Heat Control: Use medium-high heat. If the pan is too hot, the thin meat will char before the fat renders. If too low, the meat will steam in its own moisture rather than crisping up.
- Grilling Together : Often you can see grilling garlic, kimchi, etc. together. It will become more delicious with pork oil
The important thing is to golden brown and not burn. Place the meat on a properly heated grill and grill.
It should be checked that the stronger the firepower, the more delicious it is, but the more likely it is that the meat will burn.
Personally, it seems difficult at first, but gradually you'll get used to it
3. Global Trends and Personal Reflections on Naengsam
Naengsam has recently exploded on global platforms like Reddit, where Western BBQ enthusiasts frequently describe it as "Bacon on Steroids" or "Meat Candy."
In US foodie circles, the dish has become a viral meme due to its "infinite eatability"—the thin slices make it easy to joke about consuming five or six servings without feeling full, cementing its status as the ultimate late-night party food.
Online communities often discuss the "correct" way to enjoy it, emphasizing the use of Gireumjang (sesame oil, salt, and pepper) to enhance the meat's natural savoriness.
In fact, in Korea, many people dip grilled frozen pork belly BBQ in red pepper paste. It's also my personal favorite method.
The method is simple. It is a gochujang sauce made by putting gochujang on a plate and properly adding sesame oil.
I think the combination of the two will make frozen pork belly more delicious and make you feel the perfect taste of Korea.
Korean BBQ, the way to grill pork belly in Korea, personally, I really like it, but you can see it often in foreign countries these days.
Why don't you feel the charm of the part called pork belly today?
