About this dish
Saesongi-beoseot-gui is a Korean grilled king oyster mushroom dish where the mushrooms are sliced lengthwise to 0.7-centimeter thickness, seared in melted butter until golden on both sides, then glazed with a sauce of soy sauce, minced garlic, oligosaccharide syrup, and black pepper.

King oyster mushrooms contain a lot of moisture, so arranging the slices in a single layer without overlap is essential-crowding steams rather than sears, preventing the Maillard browning that gives the surface its golden color and savory depth. Butter burns quickly above medium heat, so temperature control is key, and the soy glaze should only be added after both sides are already browned so it coats the surface rather than making it soggy. Chopped chives and sesame seeds scattered on top add a nutty, aromatic layer over the salty butter-soy base.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Trim only the dry base from 300 g king oyster mushrooms, then slice them lengthwise into 0.7 cm pieces.
If the surfaces feel damp, press them with a paper towel so they sear instead of steaming.
- 2Season
Mix 1.5 tbsp soy sauce, 1 tsp minced garlic, 1 tsp oligosaccharide syrup, and 0.5 tsp black pepper in a small bowl.
Stir until the garlic is evenly loosened so the glaze spreads quickly in the pan.
- 3Control
Preheat a pan over medium heat, then melt 1 tbsp butter.
When the foaming settles and the butter smells nutty but has not darkened, lay the mushroom slices in one layer without overlap.
- 4Control
Cook the mushrooms over medium heat for 3 minutes without moving them.
When the edges turn slightly translucent and the underside is golden, flip each slice and cook 2 minutes more.
- 5Control
After both sides are browned, pour the sauce around the edge of the pan rather than directly over one spot.
Lower to medium-low heat and simmer about 1 minute, shaking the pan to coat the slices evenly.
- 6Finish
Turn off the heat when the sauce looks slightly sticky and the mushroom surfaces are glossy.
Sprinkle with 15 g chopped chives and 1 tsp sesame seeds, then plate while warm so the glaze stays shiny.
