Pressed Oyster Mushroom Steaks
Two oyster clusters, a screaming-hot cast iron, and a heavy press. That's the whole recipe. Pressing collapses a feathery cluster into a dense, browned, steak-thick slab — what was a side dish twenty minutes ago plates as a main. Finished butter, smashed garlic, a sprig of thyme, and a squeeze of lemon to wake it up.

The method
Three things matter: the pan has to be screaming hot before the mushrooms hit it, the press has to be heavy, and you have to leave them alone long enough to brown. No fussing, no peeking. Twenty minutes start to finish.
Heat the pan
Set a heavy cast-iron skillet over medium-high with a thin slick of oil. Get it hot — a flick of water should vanish on contact before the mushrooms go in.
2 minutesFirst press — 4 to 5 minutes
Lay each cluster in the pan gill-side down. Set a second heavy pan (or a foil-wrapped brick) on top and press firmly. Cook 4–5 minutes, no fiddling, until the cluster is deeply browned and has compressed into a steak.
5 minutesFlip and press again
Flip carefully with a wide spatula, replace the weight, and press the other side for another 3–4 minutes until browned and crisp at the edges.
4 minutesBaste with butter and herbs
Drop in the butter, smashed garlic, and thyme or rosemary. Tilt the pan and spoon the foaming butter over each steak for 1–2 minutes until glossy and the edges crisp up further.
2 minutesRest, season, finish
Move to a board and rest a minute. Season with flaky salt and cracked pepper, finish with a squeeze of lemon, and either slice across the grain or serve whole.

About the Oyster
A staple of our grow rooms — fast-growing, fan-shaped, and uniquely savoury. Pearl, pink, blue, yellow, and king all work for this recipe, each with its own personality. The trick is choosing clusters tight enough to hold together under a heavy press, so a couple of dense clusters beats a basket of loose petals here.

The press is the whole recipe
Any heavy weight works — a second cast-iron pan, a heavy pot, a foil-wrapped brick. What you can't skip is the weight. Without serious pressure, the cluster steams instead of compressing and you'll end up with a soggy fan, not a steak.
King oyster works too
King oysters press beautifully — slice each thick stem lengthwise, score the cut sides in a crosshatch, and follow the same method. Slightly meatier chew, equally steak-like result.
Plate it like a steak
Treat it the way you would a small steak: rest, slice across the grain on a board, plate over creamy polenta, smashed potatoes, or a sharply dressed green salad. The pan butter is the sauce — spoon it over.
