How to clean portobello mushrooms
- Use a soft-bristled brush to remove dirt and residue. Alternatively, you can clean portobello mushrooms under running water and dry them off.
- Keep or remove the stems...totally up to you. When I keep the stems on, I remove the very bottom of the stem just to make a clean edge.
- I do not peel the skin or gills away from portobello mushrooms. To me, these are part of the mushroom experience and I happen to like the texture of both.
How to cook portobello mushrooms on the grill
Step 1. Whisk together the marinade ingredients
Step 2. Clean the mushrooms, slice them into 1" think pieces, and place them in a baking dish.
Step 3. Marinate the mushrooms by pouring the marinade over them and allowing them to sit for 30 minutes (no need to refrigerate).
Step 4. Fire up the grill to medium-high and, when it's ready, grill the mushrooms in a prepared grill basket for 10-15 minute, tossing as needed to avoid burning.
I love this Weber Grill Basket because it prevents the veggies from falling through the grill. You can live without it, but it’s a really convenient tool.
Step 5. Carefully remove the grill basket and transfer the mushrooms to a plate or pan to cool. Serve warm as a side dish or stuffed into a sandwich or wrap.
