Confit is preservation by fat: cook something slowly submerged in oil, then store it in that oil, and it keeps for weeks. For mushrooms it

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.
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.
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.
425°F for most species, on a preheated pan. Hot enough to drive water off fast and brown the edges rather than slowly dehydrating them.
Overcrowded pan, cold pan, or not enough oil. Mushrooms need space so the water can escape as steam — use two trays rather than one crowded one.
Once, halfway. More than that and you interrupt the contact time that builds colour.
