King oyster mushrooms, aka pleurotus eryngii, are part of the oyster mushroom family. I’m lucky to live in the Pacific Northwest where mushrooms grow in ABUNDANCE and I’ve loved playing around with them in the 7+ years I’ve lived in Portland. These have become one of my favorite type of mushroom because of the deliciously meaty stems and just how fun they are to cook with!

Quite often, you’ll see people cut the stems into one inch slices adn then turn them into kind of vegan scallops. I love that but this teriyaki flavor is one of my go-to methods.

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 – the thick stems are 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.
Oil – I usually use extra virgin olive oil in this recipe but butter/ vegan butter also work well!
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 :)

This is a very simple recipe but let’s break it down.

Once the mushrooms are clean (I like to do this by gently wiping them clean with damp paper towels), 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. Repeat with the rest of the mushrooms.

sauteed king oyster mushrooms in a skillet

In a skillet over medium-high heat (either non stick or a cast iron pan), place the sliced mushrooms and saute 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! I like to serve with some fresh black pepper, sesame seeds, and green onion.

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.
