    Roasted oyster mushrooms with "korean mushrooms side dish" written on top.

    Ingredients

    You will need a few simple ingredients for this Korean mushroom side dish:

    • 400g (or 3-4) king oyster mushrooms: Do not use baby king oysters . The width and thickness of the mushrooms will affect the roasting time so cut into 1-1.5 inch rounds, and score the cut surface as shown above. For an average sized king oyster mushroom, this would mean cutting into 4 rounds.
    • 1 Tablespoon Korean gochujang paste
    • 1 Tablespoon oyster sauce
    • ½ Tablespoon light soy sauce
    • ½ T oil: olive oil or sesame oil

    🔪 Step-by-Step Instructions

    King Oyster Mushrooms on a baking sheet.
    1. Mix the sauces till no lumps remain. Marinate the mushrooms in the sauces for at least 20 minutes. DO NOT SKIP THE MARINATING or it won't taste good.
    2. Bake at 220/ 200C fan for 25 minutes. (Keep an eye on the oven to see if the mushrooms are burning- if so, cover with an aluminium foil.)

    Tip: The crux to roasting mushrooms in the oven is the right temperature. If it's too low, the juices will come out of the mushrooms and make them soggy. If it's too high, your shrooms and sauce will burn.

    🥡 How to Store

    So delicious, we never have leftovers, but if you do, store in an airtight container in the fridge for 1-2 days.

    Greedygirlgourmet eating 2 sandwiches in Scotland

    Hi I'm Zhen also known as GGG! I couldn't boil water till I was 18! However, I love creating community and nurturing people, so when I lived abroad (in St. Andrews then London) for 11 years, I started hosting regular parties for friends, and that's how I started cooking and helping out in professional kitchens. (Couldn't cook before that!) I even organised a supper club for charity (which strangers came to!) Learning to cook late, I make sure my recipes go into enough detail for those new to Asian cuisine or who love a test kitchen approach to cooking!
