- 2Dry-sauté the chopped mushroom stems first to remove excess moisture before adding oil.
- 3Use a small spoon or piping bag to fill the caps neatly and avoid overfilling.
- 4Let the stuffed mushrooms rest 2 minutes after baking to set the cheese and prevent burns.
- 5Make ahead by assembling and refrigerating up to 8 hours; bake just before serving.
- 6Leftover stuffed mushrooms reheat best in a 350°F oven for 5-7 minutes to restore crispness.
