Steps
1. Start by cleaning the mussels under cold running water, removing any beards.
2. In a large pot, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute.
3. Pour in the white wine and bring to a simmer.
4. Add the cleaned mussels to the pot, cover, and steam for 5-7 minutes until the mussels open up. Discard any that remain closed.
5. While the mussels are cooking, preheat your oven to 375°F (190°C).
6. Brush the slice of rustic bread with olive oil, sprinkle with salt, pepper, and chopped parsley. Toast in the oven for about 5-7 minutes until golden.
7. Once the mussels are cooked, stir in the fresh parsley and season with salt and pepper to taste.
8. Serve the mussels in a bowl with the buttery broth and the toasted bread on the side. Add lemon wedges for a zesty finish.
