When hot, working in batches, add the mushrooms in a single layer. They should sizzle. Leave some space between them so that they brown rather than steam. Brush the tops with oil.
Fry until golden brown (~5 mins per side), using a spatula to press down on the ones that bend up to get full-pan contact and uniform browning.
Transfer the done ones to a plate and repeat with the remaining shrooms, adding more oil if needed between batches.
Return all the mushrooms to the skillet, pour in the glaze, and turn off the heat.
Toss the mushrooms in the glaze, using the residual heat of the pan.
Garnish with chopped scallions and serve.
Pro Tips
Use a heat-resistant brush to coat the skillet with oil, you don't need a pool. Brush the tops of the shrooms before flipping to get good browning.
