Quick Eryngii Mushrooms (3-ingredients)

Ingredients

• To tasteVegetable oil with a high smoke point
• 4King oyster mushrooms (eryngii)
• 1 tablespoonUnsalted butter
• 1 tablespoon, or to tasteLight soy sauce
• Optional, to tasteSalt
• OptionalSpring onions, for garnish

Instructions

1. 1

   Sear the mushrooms

   Heat the oil in a pan over medium-high heat until hot but not smoking. Arrange the mushrooms in a single layer, working in batches if needed, and leave them undisturbed for a few minutes until browned.

2. 2

   Brown the other side

   Turn the mushrooms over and sear the second side for a few minutes. Transfer them to a plate once both sides are browned.

3. 3

   Finish the batches

   Repeat with the remaining mushrooms, topping up the oil as needed because the mushrooms absorb it. Take care, as the oil may splatter.

4. 4

   Make the sauce

   In the same pan, add 1 tablespoon of butter and 1 tablespoon of light soy sauce. Stir with a spatula as the butter melts and sizzles.

5. 5

   Coat and season

   Once the butter is sizzling, return all the mushrooms to the pan and mix to coat. Taste and add salt if needed.

6. 6

   Serve the mushrooms

   Serve the mushrooms, with spring onions as an optional garnish.

What are eryngii mushrooms?

Eryngii, also called king oyster mushrooms, have thick stems and a firm texture that holds up well to searing. They are used in a range of East Asian cooking, including Chinese-style dishes.

Here, browning gives them savoury edges, while butter and light soy sauce make a quick, glossy coating. The short ingredient list lets the mushrooms remain the focus.

Nutrition and macros by portion

The nutrition label shows one serving as written: 28 calories, 1g protein, 0g carbs, 3g fat.

The mushrooms contribute most of the small amount of carbohydrate and protein, while the vegetable oil and butter provide most of the fat. Serve them with rice or noodles and a protein-rich dish to make a more balanced plate.

Choosing the ingredients

Mushrooms: Choose firm king oyster mushrooms and slice them into pieces that will sit flat in the pan for even contact with the heat.

Oil and soy: A high-smoke-point vegetable oil helps with searing, while light soy sauce brings saltiness. Brands vary, so taste before adding extra salt.

Getting a good sear

Hot pan: Heat the oil until it is hot but not smoking before adding the mushrooms. Leave each batch alone for a few minutes so the surfaces can brown rather than steam.

Small batches: Keep the mushrooms in a single layer with room around them. The recipe’s 7.5-inch pan needed two batches, though the number will depend on your pan and mushroom size.

Finishing with butter and soy

Sizzling butter: Stir the butter and soy sauce together in the same pan, letting the butter melt and sizzle before returning the mushrooms.

Even coating: Toss the browned mushrooms in the mixture so the sauce reaches their surfaces. Taste at the end and add salt only if the soy sauce has not seasoned them enough.

Texture and timing

The mushrooms are ready for the sauce when both sides are visibly browned; keep the pan hot enough to sear, but not so hot that the oil smokes. The full recipe takes about 25 minutes, with the batches accounting for some of that time.

Avoid moving the mushrooms around while each side is browning. Turn them once they have developed colour, then finish them briefly in the pan with the sauce.

What to serve with them

Serve the mushrooms as a side alongside rice or noodles, or add them to a larger spread of vegetable dishes. Spring onions make an optional fresh garnish.

For a more substantial meal, pair them with a protein-rich dish and another vegetable. Keep the mushrooms warm and serve soon after coating for the best seared texture.

Recipe notes & tips

• Use an oil with a high smoke point and stop heating it before it begins to smoke.
• Arrange the mushrooms in a single layer and sear them in batches if needed.
• Leave each side undisturbed for a few minutes to help it brown.
• Top up the oil between batches if the mushrooms have absorbed it.
• Taste the sauce before adding salt, as light soy sauces differ in saltiness.
• Watch for splattering oil when cooking the mushrooms.

Variations

• Spring onion garnish: Scatter sliced spring onions over the mushrooms just before serving.
• Soy to taste: Adjust the light soy sauce slightly to suit its saltiness and your preference.
• Salt-free finish: Skip the optional salt if the soy sauce already seasons the mushrooms well.
• Oil choice: Use another high-smoke-point vegetable oil for the searing.
• Serve with rice: Pair the mushrooms with rice to make a simple, more filling meal.

Common mistakes to avoid

• Crowding the pan: The mushrooms may steam instead of brown; cook them in batches in a single layer.
• Moving them too soon: They need time to brown; leave each side undisturbed for a few minutes.
• Smoking oil: It is too hot for searing; lower the heat and wait until the oil is hot but not smoking.
• Running out of oil: The mushrooms absorb it as they cook; top it up between batches as needed.
• Over-salting: Soy sauce brands vary; taste the finished coating before adding salt.
• Ignoring splatter: Oil may spit during cooking; take care when turning and transferring the mushrooms.

How to store

Refrigerate leftovers in a covered container and use within 3 days. Reheat gently in a pan until hot, taking care not to overcook the mushrooms.
