Ingredients Needed

The simple ingredients for this king oyster mushroom recipe are listed fully down in the recipe card but let’s briefly go over the pantry staples needed including a few substitutions you can make as desired!

King oyster mushrooms – sliced in half lengthwise and scored on the cut side to help them soak up the sauce and caramelize beautifully! I typically get these at my local Asian markets.

Soy sauce or tamari – the salty, umami base of the sauce.

Maple syrup, honey, or brown sugar – adds that lightly sweet, sticky finish.

Rice vinegar – balances the sweetness and brightens the sauce.

Garlic – fresh is best here but garlic powder or pre-minced garlic also work well!

Fresh ginger – optional but highly recommended for that teriyaki-adjacent flavor. You could swap it for ground ginger as needed.

Optional garnishes: sesame seeds, sliced green onions, chili crisp or chili oil.

How to make it

Just a reminder that you can find the FULL written king oysters recipe down in the recipe card, but I want to quickly go over how to make it with visuals for you 🙂

Once the mushrooms are clean, cut them in half lengthwise and score the cut side of the thick white stems. This isn’t necessary but it helps the sauce really seep into the mushrooms while they cook and just overall taste better.

In a skillet over medium-high heat, sauté the mushrooms for 4 minutes on the flesh side until a light golden brown, flip and cook an additional few minutes.

In a small bowl, whisk together the ingredients for the homemade teriyaki glaze.

Reduce the heat and pour the sauce into the pan with the cooked mushrooms. Cook for a few minutes until the sauce is thick and sticky!

Expert Tips

Don’t rush the browning – letting the mushrooms sit undisturbed in the pan creates better caramelization!

Scoring the mushrooms is optional, but highly recommended for both texture and sauce absorption.

If the sauce thickens too quickly, add a splash of water to loosen it.

For extra depth, add a small drizzle of sesame oil at the very end.

Want heat? Stir in chili garlic sauce or top with chili crisp. SO GOOD!

Frequently Asked Questions

Can I use regular oyster mushrooms instead of king oyster mushrooms?

Yes, but the texture will be softer and less “steak-like.” Reduce cooking time slightly.

Is this a true teriyaki sauce?

Not exactly – it’s inspired by teriyaki flavors but simplified and pan-friendly, with a sticky glaze rather than a marinade.

What do king oyster mushrooms taste like?

King oyster mushrooms have a mild flavor with a rich, savory undertone. They take on the taste of whatever sauce they’re cooked in, making them ideal for sticky, soy-based or teriyaki-style glazes.

Do king oyster mushrooms need to be washed?

It’s best to wipe king oyster mushrooms clean with a damp paper towel instead of rinsing them under water. They absorb moisture easily, which can prevent proper browning when sautéed.

Why score king oyster mushrooms?

Scoring king oyster mushrooms helps them absorb more flavor and cook more evenly. The shallow cuts also create extra surface area, which allows sauces to cling better and gives the mushrooms a more caramelized, restaurant-style finish.

Ingredients

4 large king oyster mushrooms cleaned, trimmed, and sliced in half lengthwise1 tablespoon olive oil or sesame oil for extra flavor1 tablespoon soy sauce1 tablespoon maple syrup or honey if not vegan1 tablespoon rice vinegar1 teaspoon brown sugar1 teaspoon cornstarch2 tablespoons water2 cloves minced garlic (or 1/4 teaspoon of garlic powder)½ teaspoon grated fresh ginger (or 1/4 teaspoon of ground ginger)Optional garnish: sesame seeds thinly sliced green onions

Instructions

Slice the mushrooms in half lengthwise. Using a sharp knife, lightly score the flat sides in a crisscross pattern — this helps them soak up the sauce and look extra fancy once caramelized.
In a small bowl, whisk together the soy sauce, maple syrup, rice vinegar, brown sugar, cornstarch, water, garlic, and ginger until smooth. Set aside.
Heat the oil in a large skillet over medium-high heat. Place the mushrooms cut-side down and cook for 3–4 minutes without moving them, until golden and slightly crisp. Flip and cook another 2–3 minutes on the other side.
Pour the sauce into the pan and reduce the heat to medium. Stir or toss the mushrooms frequently as the sauce thickens and becomes glossy, coating the mushrooms evenly. This should take about 2–3 minutes.
Remove from heat once the sauce is sticky and clings to the mushrooms. Sprinkle with sesame seeds and green onions before serving.

Notes

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in a skillet or microwave until warmed through.
