Slice your mushrooms and garlic cloves. In a skillet or cast iron, heat and melt your butter until shimmering on medium-low heat. Add in your mushrooms and allow them to cook down.
Then add in your salt and pepper and minced garlic and saute for 10-15 minutes.
Next add in your white wine and let that reduce down until the mushrooms are crispy and cooked throughout - about 30 minutes.
Turn off the heat and add a bit of lemon juice. Serve on toasty bread and top with parsley, salt and lemon zest.
