Add oil + butter to a large non-stick pan, then turn on the stove to medium-high heat.
Once the butter melts, quickly add the mushrooms. The pan should not be overcrowded. Let them cook for 4 minutes... do not touch them!
After 4 minutes {or until crispy and brown}, toss the mushrooms around and as best as you can, flip them over! Let cook for another 4 minutes until crispy and brown on the other side.
Add white wine to deglaze.
About 45 seconds to a minute after adding the wine, stir in garlic, and then a minute after that stir in the chopped fresh cilantro. Then add salt and pepper to taste. Add in more salt than you find necessary. It brings out all the flavors even more!
