Roasted oyster mushrooms.

A stovetop pan can only brown as much mushroom as fits in one layer, which is roughly half of what most people try to put in it. An oven does not have that constraint — a preheated sheet pan at 425°F browns a full pound at once, evenly, with nothing to watch.

Three rules: preheat the pan, use enough oil, and give the mushrooms space.

What you need

Base

• 1 lb oyster mushrooms, torn into large pieces
• 3 tbsp olive oil
• 1 tsp salt
• Black pepper

Finishing (pick one)

• Butter, garlic and thyme, tossed hot from the oven
• Soy, mirin and sesame
• Lemon zest, parsley and flaky salt
• Sherry vinegar and shallot

Method

1. Heat the oven to 425°F with the sheet pan inside it. A cold pan is the difference between roasted and steamed.
2. Tear the mushrooms into pieces about two inches across, trimming the woody base. Keep them chunky — small pieces dry out before they brown.
3. Toss with oil and salt in a bowl. Be generous with the oil: mushrooms are absorbent and under-oiled ones go leathery.
4. Spread on the hot pan in a single layer with space between the pieces. Use two pans rather than crowding one — this is the only real mistake available here.
5. Roast 12–14 minutes, turning once at the halfway mark, until the edges are crisp and dark and the centres are tender.
6. Finish immediately off the pan while they are still hot enough to absorb whatever you add — butter and garlic, soy and sesame, or just lemon and flaky salt.

Timings by species

• Blue oyster, black pearl: 12–14 minutes.
• Golden oyster: 8 minutes — thin flesh, and bitter if pushed. See the species page.
• Pink oyster: 15–18 minutes, deliberately hard, until the edges shatter.
• King trumpet: cut into coins first, 15 minutes.
• Maitake: in wedges at 450°F, 15–20 minutes — full method here.

Roast a double batch. Cold roasted mushrooms are the best thing to find in a fridge — into eggs, onto toast, through a grain bowl, folded into pasta.

Uses

A side dish on its own. Or: on labneh with dukkah, over polenta, in a grain bowl, piled on sourdough with a fried egg, or stirred through pasta at the last moment.
