Preheat the oven to 475 degrees Fahrenheit.
Boil 4 cups of water in a large pot over high heat then pour in the white wine and lemon juice and bring it back to a boil.
Gently add the mussels to the water and cover and let them steam for about 3 minutes or until they have all opened.
Strain them from the water and place them in a colander to cool but do not discard the water in the pot.
While the mussels are cooling, melt the butter in a small saucepan over medium heat then stir in the garlic and let cook for 30 seconds.
Stir in the salt and pepper then remove the pan from the heat and set aside.
Remove the empty shells from the mussels then place the halves with the meat in them face up on a large baking pan, evenly spaced.
Drizzle 3 to 4 tablespoons of boiled water mixture evenly over top of the mussels then drizzle the butter mixture on top.
Sprinkle the tops with the Parmesan cheese and freshly minced parsley.
Bake for 3 to 4 minutes or until the cheese is fully melted. Serve immediately with more freshly minced parsley for garnish and lemon wedges if desired.
