Been washing all kinds of mushrooms for years and I‘ve had the opposite experience. They’re only soggy if they’ve been cooking in oil, soaked it up, then dumped all their water. They don’t get brown as they soak up the oil, and then they dump it all out with the water, meaning you’re just steaming them until you evaporate off all the water.
Best is to wash the mushrooms, slice, cook in a little bit of water until they dump out their water, cook until the water has evaporated, then add oil and brown (or even crisp if you desire).
Perfect mushrooms every time (I’ve dated a lot of vegans so I’ve eaten mushrooms every few days for over a decade).
