This is an easy recipe that can be made in almost any amount.

Preheat oven to 375 degrees F.

Add a rack to a sheet tray. Add foil to the top of the rack. (For easy cleanup, foil may be added to the sheet tray under the rack.) Toss mushrooms in oil, then place on sheet tray. Lightly salt. Scatter garlic cloves and rosemary sprigs. Place in oven and roast for about 15 to 20 minutes, until golden brown. Watch closely. Timing will vary depending on the size of the mushrooms, the amount of moisture they hold, and the temperature and circulation variation of your oven.

Remove, discard the rosemary, and use mushrooms and garlic as desired.

Stores well in a tightly covered container for three to four days.
