Heat butter and olive oil in a large skillet over medium heat until butter is just melted, then swirl to coat the pan. Stir in the mushrooms and saute for three minutes, undisturbed.
Stir in the garlic and continue to saute over medium heat for three more minutes or until mushrooms are golden brown, stirring occasionally.
Stir in the soy sauce and saute for another minute or so, or until mushrooms are nicely glazed and most of the liquid has evaporated.
Serve: As a side dish, as a topping for steak, on avocado toast as shown here, as a topping in a baked potato bar, on grilled chicken…
Notes
This recipe makes two servings, but easily doubles to serve four — or, if you just want extras… 😉
