Brown these and repeat the process until all the mushrooms are browned. A few easy ways to add flavor Add flavor with a sprinkling of minced garlic and chopped parsley. Cook for another minute or two, tossing to coat the mushrooms evenly. Season with salt and pepper and serve. The fat you use is the first way you can add flavor.
Butter tastes great, but it's tricky because it burns at a lower temperature.
Clarified butter, on the other hand, works beautifully. Olive oil adds a lovely, fruity flavor, but I don't recommend using extra-virgin olive oil because the high heat eliminates any of the nuances of this more expensive grade. Cook a panful of mushrooms until the water is released and then evaporated Mushrooms crowded in a pan will release a lot of water. Keep the heat on high as the mushrooms cook to evaporate the liquid quickly. Deglaze the pan to capture the most flavor.
