I used smaller baby portabella mushrooms but you can use any mushrooms you wish, even mixing up types when you make herb roasted mushrooms on the Char-Broil Big Easy. Just keep in mind that larger mushrooms or mushrooms with thicker caps might take a bit longer to cook.
In a large bowl, toss mushrooms with the remaining ingredients.
Transfer mushrooms to the Big Easy. Make sure the stem-side is pointing upwards.
Place into the Big Easy and cook 20 minutes or until just tender.
Notes
The easiest way to cook these mushrooms is to use a Big Easy Cooking Rack with 9" pie pans. If you don't have either, you can use the Big Easy Bunk Bed Basket..
