Gently clean the mushrooms with a damp cloth and trim any dry ends from the stems. Halve or quarter any larger mushrooms so they are all roughly bite-sized.
In a large skillet or fireproof casserole over medium heat, melt the butter.
Add the chopped garlic and sauté for about 30-60 seconds until fragrant and just beginning to turn golden. Be careful not to let it burn.
Increase the heat to high, add the prepared mushrooms and most of the chopped parsley (reserving some for garnish) to the skillet.
Sauté, stirring often, for 3-5 minutes until the mushrooms start to release their liquid.
Pour in the dry white wine, season generously with salt and freshly ground black pepper, and stir to combine.
Bring the mixture to a simmer.
Reduce the heat to low, cover the skillet, and let the mushrooms simmer for 10-15 minutes, or until they are tender and have absorbed the rich flavors of the sauce.
Taste and adjust seasoning if necessary.
Serve immediately in warm bowls, garnished with the remaining fresh parsley.
Don't forget plenty of crusty bread for soaking up the delicious garlic wine sauce!
