Wipe mushrooms with a damp cloth until all dirt is removed. Place cleaned mushrooms on a paper towel-covered plate and allow to dry for about 3 minutes before adding them to the hot oil.

Place olive oil in a skillet. Place skillet over high heat and heat until oil is hot and shimmering.

Carefully add mushrooms to skillet. Sauté, stirring occasionally with a wooden spoon, until lightly browned and most of the water is reduced out of mushrooms, about 10 minutes.

Reduce heat on skillet.

Add garlic, onion and thyme. Sauté for 1 minute, stirring constantly to keep garlic from burning.

Add steak spice.

After the liquid boils, turn heat on skillet down.

Add butter. Simmer until thickened, about 3 - 5 minutes.

Serve hot as a side or topping for any dish you like.
