How long to roast mushrooms
Depending on the size of your mushrooms, they shouldn’t take more than 15 minutes in a hot oven. You also want to make sure the garlic is cooked through so 10-15 minutes at 200ºC/390ºF should be perfect.
Can I make roasted mushrooms in advance?
You can prep the mushrooms completely (without roasting) and cover with foil then leave at room at room temperature for up to 3 hours or refrigerate overnight. Uncover and roast as instructed.

I like to add the crushed garlic and minced parsley to the melted butter, remove the tough stems, then brush first the tops and then turn over on your parchment-lined sheet pan and drizzle the solids+butter on the gills. Sometimes I’ll add EVOO to the butter — the juicier the better, because when they’re done roasting I take my brioche burger buns, turn them cut-side down, and sop up all those juices. To build the burger, I use Kewpie mayonnaise on both inner sides of the buns, then I’ll lay down some romaine or arugula, then the mushrooms. Tomatoes (fresh-sliced), onions (red), and cheese (Swiss) all optional if I’m lazy and in a hurry to stuff my face. Kosher salt and fresh-ground pepper. So so good.
