Use whole cremini, button, portobello, or shiitake mushrooms — firm varieties hold up over direct heat. Wipe clean with a damp cloth; skip washing to avoid steaming. Remove woody stems. Leave small mushrooms whole and skewer through the caps; slice larger ones about ½ inch thick. Soak wooden or bamboo skewers in water for at least 30 minutes before grilling. If marinating, coat and rest at room temperature for 1–8 hours max — longer makes them soggy. Brush or toss with oil or butter just before grilling to promote browning and prevent sticking.

Preheat your grill to medium-high. For charcoal, use a full chimney and position mushrooms toward the middle of the grate. For gas, set burners to medium-high and preheat covered for 10 minutes. Clean and oil the grate well before adding mushrooms to prevent sticking. For large caps like portobello, place flat side down and grill 4–5 minutes, rotate 90° for another 3–4 minutes to get crosshatch marks, then flip for a final 2–3 minutes. For smaller mushrooms or skewers, grill 3–5 minutes per side. Total time: 8–12 minutes depending on size and thickness. Baste with butter, marinade, or soy-butter glaze every few minutes and at each flip. Keep the grill covered between turns. Mushrooms are done when they've shrunk noticeably, released liquid, and have a browned, slightly caramelized exterior.

Mushrooms are done when tender, pliable, and browned with grill marks, and have released some juices. They should feel soft when pressed but not mushy. Pull them off promptly — overcooking causes moisture loss and a rubbery texture. Serve immediately. Finish with grilled lemon, fresh dill, or a drizzle of olive oil. Leftovers keep refrigerated up to 4 days. Reheat on a baking sheet at 177°C for 10 minutes or warm in a skillet with butter. Avoid microwaving. Common mistakes: too much marinade (makes mushrooms wet, blocks browning), skipping oiled grates (causes sticking), crowding skewers (traps steam, slows caramelization).
