Pan-fried king oyster mushroom cooked in one pan with thyme and lemon flavors.
📕 What are King Oyster Mushrooms?
King oyster mushrooms are also known as king trumpet mushrooms, royal trumpet, and some other regional names.
They are part of the oyster mushroom family. Remember those mushrooms growing on trees? Well, that's the same mushroom family.
So, while they don't grow on dying tree stems, they choose to instead grow on dying tree roots.
They have been commercialized in the west and east and appear occasionally on local regional menu cards.
For example, in Germany and Austria, you can find them under the name Kräuterseitlinge. Yet the mushroom is also quite popular in east Asian cuisine.
The most common and best way to enjoy them is sliced and sauteed in a skillet, just like scallops. This is how they earned the vegan scallop title.
The texture is meaty, a bit chewy and when cooked they turn out flavorful, umami. Almost like shiitake!
Here is an overview of what you will need to make these lemon thyme-flavored king trumpet mushrooms.
The full US and metric measurements are located further below in the recipe card.

Fresh king oyster mushrooms don't spoil that fast, they are quite hardy.
But I don't recommend keeping them for too long because mold can grow on your fresh mushrooms.
Use them up within 2 days after you have purchased them.
The finished dish itself can be stored in your fridge for up to 3-4 days.
Reheat the mushroom slices in a skillet and enjoy them with your food.
They are mainly available in late spring and fall but can be bought in stores during that period too. Homegrown mushrooms will thrive best in fall and you will find them in the woods in the northern hemisphere from August up to November.
If they are in season, you can buy your king trumpet mushrooms in local farmers' markets. You get them online too on freshdirect. Some larger hyper stores carry them all year round too. Your neighborhood Asian store might sell them too. Keep your eyes peeled, they might just appear when you least expect it.
Yes, the whole mushroom can be consumed and everything tastes great.
I think porcini mushrooms resemble king oyster mushrooms in their consistency and also in flavor. Large shiitake mushrooms can be also used instead.
Mushrooms with gills shouldn't be rinsed with water because water gets trapped in the gills and the mushroom also loses on flavors when rinsed. Professional chefs brush mushrooms with a mushroom brush. The problem is that commercially available mushrooms tend to be treated with pesticides and you really don't know where they came from. So, in those cases, I recommend taking them through some running water quickly and then pat them dry very well and carefully so as to not damage your mushroom. If your mushrooms are just muddy, I recommend wiping them off with a damp clean cloth. I also recommend only buying mushrooms that are labeled as pesticide-free. Organic (or Bio) doesn't always mean no pesticides because every country has different labeling laws.
