🥢 Introduction
This Korean braised king oyster mushroom dish brings back memories of when I first started living on my own. Back then, I was always looking for simple and affordable ingredients that could make a satisfying meal without spending much money. King oyster mushrooms were one of my go-to ingredients because they were inexpensive, easy to cook, and had a chewy texture that made them feel surprisingly hearty.
I used to make this dish when I wanted something warm and comforting but didn’t want to spend too much time in the kitchen. A bowl of freshly cooked rice with these savory mushrooms was often all I needed for a simple meal. The mushrooms soak up the soy-based sauce beautifully, and their texture makes them much more satisfying than you might expect from a vegetable dish.

In Korea, this dish is called saesongi beoseot jorim. It’s a simple homemade banchan made by simmering whole king oyster mushrooms in a savory sauce with soy sauce, garlic, and oyster sauce. After the mushrooms absorb all the flavors, they are sliced and served, creating a tender yet chewy side dish that goes perfectly with warm rice.
It’s one of those humble Korean dishes that reminds me how a few simple ingredients can still make a meal feel special.
🛒 Ingredients
✔ 3 king oyster mushrooms – Use whole mushrooms for this recipe. Cooking them first helps the mushrooms absorb the sauce while keeping their chewy texture. Slice them after they are fully seasoned.
✔ 3 tbsp soy sauce– This gives the mushrooms their main savory flavor. Korean jin ganjang works well for this recipe
✔ 1 tbsp oyster sauce – Adds extra depth and umami to the sauce.
✔ 1 tbsp sugar – Balances the saltiness and gives the sauce a slightly sweet flavor.
✔ 1 tbsp minced garlic – Adds a fragrant garlic flavor that pairs well with the mushrooms.
✔ 100 ml water – Helps create enough sauce for the mushrooms to simmer and soak up the seaso

🍳 How to Make Korean Braised King Oyster Mushrooms
Step 1. Prepare the Mushrooms
Gently rinse the king oyster mushrooms under running water to remove any dirt. Avoid soaking them for too long, as mushrooms can absorb water. Pat them dry with a paper towel, then keep them whole before cooking.

Step 2 – Add the Sauce Ingredients
Place the whole king oyster mushrooms in a pan. Add soy sauce, oyster sauce, sugar, minced garlic, and water directly over the mushrooms. Gently mix everything together so the mushrooms are evenly coated with the seasoning.

Step 3 – Simmer the Mushrooms
Turn on the heat and cook over medium heat. As the sauce begins to simmer, turn the mushrooms occasionally so they absorb the seasoning evenly. Continue cooking until the mushrooms become tender and the sauce reduces slightly.

Step 4 – Slice and Serve
Remove the mushrooms from the pan and let them cool slightly. Slice them into bite-sized pieces and serve with the remaining sauce poured over the top. Enjoy with warm steamed rice.

🍽️ Serving Tips
Serve this Korean braised king oyster mushroom dish with a bowl of warm steamed rice. The savory soy-based sauce pairs especially well with rice, making it a simple but satisfying homemade meal.
This mushroom jorim also makes a great addition to a Korean-style meal as a banchan. It pairs nicely with other side dishes and adds a rich umami flavor to the table without being too heavy.
It’s also a perfect option for lunchboxes because the flavor becomes even deeper as the mushrooms sit in the sauce. If you have leftovers, store them in the refrigerator and enjoy them the next day—the seasoning has more time to soak in, making the dish even more flavorful.

❓ FAQ
Q. Can I slice the king oyster mushrooms before cooking?
Yes, you can. Sliced mushrooms absorb the seasoning more quickly, so they are a good option if you want the flavor to develop faster. However, slicing them before cooking can cause them to lose some of their natural moisture and slightly change the texture. Cooking the mushrooms whole first helps keep their juicy and chewy texture, which is why I prefer this method for this recipe.
Q. Can I skip oyster sauce?
Yes. Oyster sauce adds extra depth and umami to the dish, but you can leave it out if you don’t have any. You can adjust the soy sauce and sugar slightly to balance the flavor, and the mushrooms will still be delicious.
Q. How should I store leftover king oyster mushroom jorim?
Store the leftovers in an airtight container in the refrigerator for up to 3–4 days. The flavor often becomes even richer the next day because the sauce has more time to soak into the mushrooms.
Q. What is the best way to serve this dish?
This mushroom jorim is best served with warm steamed rice. It also makes a great Korean banchan, lunchbox side dish, or topping for a simple rice bowl.
Q. Can I use other mushrooms instead of king oyster mushrooms?
Yes, but the texture will be different. King oyster mushrooms work especially well for this recipe because they have a firm, chewy texture and absorb the savory sauce while keeping their shape.
