Make Ahead and Freezing Instructions
Make Ahead Instructions
- Marinate the mushrooms in olive oil and balsamic vinegar up to 24 hours before grilling.
- Toast the buns a day ahead and store them in an airtight container.
Freezing Instructions
- Grill the mushrooms, let them cool completely, then wrap individually in plastic wrap and foil.
- Freeze the wrapped mushrooms in a single layer on a baking sheet, then transfer to a freezer bag.
- To reheat, thaw in the fridge overnight and warm in a 350°F oven for 10-15 minutes.
