Korean Mushroom Porridge (Beoseotjuk) Recipe

Korean mushroom porridge, or beoseotjuk, is a comforting rice porridge made by gently simmering rice with mushrooms until the grains soften and the pot turns creamy. This version uses fresh mushrooms, garlic, and sesame oil for a savory, satisfying bowl; Korean households and recipes vary in their choice of mushrooms, broth, and seasonings.

Ingredients

1 cup (190 g) Korean short-grain rice, or sushi rice
7 cups (1.65 L) low-sodium vegetable broth or water
6 oz (170 g) shiitake mushrooms, stems removed and caps sliced
5 oz (140 g) oyster mushrooms, torn into bite-size pieces
1 tablespoon (15 ml) toasted sesame oil
2 medium garlic cloves (about 6 g), finely minced
1 tablespoon (15 ml) regular soy sauce
½ teaspoon (3 g) fine salt, plus more to taste
2 scallions (about 30 g), thinly sliced, for serving
1 teaspoon (3 g) toasted sesame seeds, for serving
1 teaspoon (5 ml) toasted sesame oil, for serving, optional

Instructions

Put the rice in a bowl and cover it with cool water. Swirl the grains with your fingers, pour off the cloudy water, and repeat until the water is less cloudy, usually three or four rinses. Drain the rice well while you slice the shiitakes, tear the oyster mushrooms, mince the garlic, and slice the scallions. Rinsing removes some surface starch, while the rice still releases enough starch during cooking to make the porridge creamy.
Set a heavy-bottomed pot or Dutch oven over medium heat and add the tablespoon of sesame oil. When it shimmers, add the mushrooms and cook for about 4 minutes, stirring occasionally, until they soften and begin to release moisture. Stir in the garlic and cook for 30 seconds, just until fragrant. Avoid browning the garlic; it can become bitter and distract from the mild mushroom flavor.
Add the drained rice and stir for 1 minute so the grains are coated in the sesame oil and mingle with the mushrooms. Pour in the broth or water, then stir in the soy sauce and salt. Scrape the bottom of the pot to loosen any rice that may be sticking. Bring the mixture just to a boil over medium-high heat, stirring once or twice; watch closely because rice can foam up as it boils.
Lower the heat to maintain a gentle simmer and leave the pot partly covered, with the lid slightly ajar to let steam escape. Cook for about 35 minutes, stirring every 5 minutes or so and more often near the end. The rice should be very soft, the mushrooms tender, and the liquid thickened but still loose enough to ladle. If the bottom starts catching, lower the heat and stir thoroughly before continuing.
Check the texture and seasonings. For a looser porridge, stir in hot water or broth ¼ cup (60 ml) at a time; for a thicker bowl, simmer uncovered for a few extra minutes, stirring frequently. Add more salt or soy sauce a little at a time. The flavor should be gently savory rather than strongly salty, since each diner can add more seasoning at the table.
Ladle into warm bowls and finish with scallions, sesame seeds, and a small drizzle of sesame oil if desired. Serve while hot. The porridge thickens as it stands, so keep a little hot water or broth nearby for loosening the bowls if serving is delayed.

Tips

Choose rice that releases starch. Korean short-grain rice gives the porridge a cohesive, softly creamy texture. Japanese sushi rice is a practical substitute and behaves similarly. Long-grain rice can be used in a pinch, but the grains tend to stay more separate and the result will be less silky; stir it well and expect to adjust the liquid.
Use broth that suits your table. Low-sodium vegetable broth keeps this recipe vegetarian and adds savory depth. Water makes a clean-tasting porridge and lets the mushrooms stand out, while unsalted chicken broth is another common home-style option if you do not need a vegetarian dish. If your broth is salted, reduce or omit the measured salt until the end.
Keep the simmer gentle and stir regularly. A hard boil can make rice stick to the base before the grains soften. A heavy pot helps distribute heat, and stirring every few minutes—especially once the porridge thickens—prevents scorching. If it becomes too thick before the rice is tender, add hot liquid rather than turning up the heat.
Season in small additions. Soy sauce and salt vary in intensity, and reducing the liquid concentrates their flavor. Add the listed amount, then taste near the end. If you want a deeper Korean-style savory note, a small splash of soup soy sauce (guk-ganjang) can replace some regular soy sauce; it is saltier and lighter in color, so use it sparingly.

Serving Suggestions

Serve beoseotjuk as a warm breakfast, a light lunch, or a simple supper. It is filling on its own, but Korean meals often pair porridge with small, flavorful side dishes. Try a modest serving of kimchi, seasoned spinach, pickled radish, or cucumber muchim alongside it. Their crisp or tangy flavors contrast nicely with the soft rice. If serving kimchi, remember that it can be salty and spicy, so taste the porridge before adding extra soy sauce.

For a more substantial meal, add a plate of pan-fried tofu or a simple vegetable pancake. Keep the porridge itself mild and put extra scallions, sesame seeds, soy sauce, and toasted sesame oil on the table so everyone can customize their bowl. A cup of roasted barley tea or green tea is also a pleasant, non-sweet accompaniment. If serving several people, offer the porridge soon after it is ready: it naturally thickens as it cools, and a little hot broth stirred in restores a spoonable consistency.

Variations

Make it with a single mushroom. Use 11 oz (310 g) of shiitake, oyster, cremini, or king oyster mushrooms instead of the two-mushroom mixture. Shiitake gives a pronounced woodsy flavor; cremini is familiar and mild; king oyster mushrooms have a pleasantly firm bite. Slice larger mushrooms thinly so they soften at the same pace as the rice.

Add dried shiitakes for extra depth. If you have dried shiitake mushrooms, soak 2 or 3 (about 10 g) in 1 cup (240 ml) warm water until pliable, usually 20 to 30 minutes. Remove and slice the mushrooms, then strain the soaking liquid through a fine sieve and use it as part of the measured broth. The soaking step adds time, and the flavor is more concentrated than with fresh mushrooms; reduce the soy sauce if needed after tasting.

Use a different stock. Water is entirely suitable, while vegetable or chicken broth makes the bowl taste fuller. Korean anchovy-kelp stock is a traditional savory option in some kitchens, but it is not essential. If it is unavailable, use a good vegetable broth or water; the result will be less briny and sea-scented, but the mushrooms and sesame oil still make a flavorful porridge. For a vegetarian version, check that prepared stock contains no fish or meat.

Finish with gentle heat or extra vegetables. A pinch of gochugaru at the table adds warmth without changing the cooking method. For more vegetables, stir in ½ cup (50 g) finely chopped carrot or zucchini with the mushrooms; small pieces will soften during the simmer. Add leafy greens, such as spinach, during the last 2 minutes so they wilt without losing their color. Avoid loading the pot with too many add-ins, which can make the rice-to-liquid balance unpredictable.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a shallow, covered container. Keep the porridge refrigerated for 3 to 4 days. Rice dishes should not be left at room temperature for an extended period, and the pot is best divided into smaller portions so it cools more quickly. The porridge will become quite thick in the refrigerator as the rice absorbs liquid; that is normal.

To reheat one portion on the stovetop, put it in a small saucepan with a splash of water or broth and warm over medium-low heat, stirring often until steaming hot throughout. Add more liquid a tablespoon or two at a time until it reaches the consistency you like. For microwave reheating, place a portion in a microwave-safe bowl, cover loosely, and heat in short intervals, stirring between them and adding liquid as necessary. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. Reheat only the portion you plan to eat, since repeated cooling and reheating can affect both quality and safe handling.

For longer storage, freeze cooled portions in airtight freezer-safe containers, leaving a little room for expansion. Use within about 2 months for best quality. Thaw overnight in the refrigerator or reheat gently from frozen with extra water or broth, stirring frequently so the rice warms evenly. The mushrooms may soften further after freezing, but the porridge remains useful for a quick meal.

Frequently Asked Questions

What does beoseotjuk mean?
Beoseotjuk is Korean mushroom rice porridge: beoseot refers to mushrooms and juk is porridge. Recipes differ by household and region, including which mushrooms and stock are used. This version uses fresh shiitake and oyster mushrooms, but it is not the only way to make the dish.

Do I need to soak the rice first?
No. Rinsing and draining short-grain rice is enough for this recipe, and it cooks through during the 35-minute simmer. Soaking can shorten the cooking time in some porridge recipes, but it also changes the timing and how much liquid the grains absorb. If you choose to soak, drain it well and begin checking the texture earlier.

Can I use cooked rice instead of uncooked rice?
Yes, but the method and timing change. Start with about 3 cups (450 g) cooked rice and use roughly 4 cups (950 ml) broth, simmering gently until the rice breaks down and the porridge reaches your preferred consistency, usually about 20 to 25 minutes. Stir frequently and add more liquid as needed. The texture may be less even than when uncooked rice cooks directly in the pot.

Why is my porridge too thick or too thin?
Rice absorbs liquid at different rates, and porridge continues thickening as it rests. If it is too thick, stir in hot water or broth gradually. If it is too thin and the rice is already tender, simmer uncovered for a few minutes, stirring to keep the bottom from sticking. If the grains are still firm, keep simmering gently with the pot partly covered instead of reducing the liquid quickly.

Can I make Korean mushroom porridge ahead?
You can cook it in advance and refrigerate it, but it will firm up as it cools. Reheat it slowly with water or broth, stirring until it is loose and steaming throughout, and follow the leftover reheating guidance above. For the freshest texture, you can slice the mushrooms and scallions ahead, then cook the rice porridge shortly before serving.

Is this recipe gluten-free?
Not as written if you use ordinary soy sauce, which commonly contains wheat. Choose a certified gluten-free soy sauce or tamari and check the broth label for gluten-containing ingredients. The rice, mushrooms, garlic, and sesame oil are naturally gluten-free, but labels and cross-contact practices matter when cooking for someone who must avoid gluten.
