Fresh shiitake mushrooms work well in stir-fries, soups, risottos, omelets, stuffing, or as a meat substitute. They can also be steamed.
Pair shitakes with flavors like basil, bacon, soy sauce, edamame (soy beans), garlic, onions, herbs (particularly rosemary & sage), balsamic vinegar, spinach, asparagus, miso, tofu, Japanese bunching onions (aka negi), poultry, seafood (especially white fish), pork and bell peppers.
Before cooking, clean them gently with a damp paper towel to remove dirt. Do not soak them.
