Method

Step-by-Step Instructions

Start by rinsing your fresh oysters under cold water. If whole, use a towel and an oyster knife to shuck them safely. Aim for a smooth extraction and set aside.
In a large skillet, melt 2 tablespoons of butter over medium heat. Add 3 minced garlic cloves and sauté until fragrant, about 1 minute. Toss in 4 cups of fresh spinach, stirring until it wilts, about 2 minutes. Remove from heat and let cool slightly.
In a mixing bowl, whisk together 1 cup of heavy cream, 1 cup of grated Parmesan cheese, and a pinch of nutmeg, salt, and pepper to taste. Mix until the cheese dissolves and the sauce is smooth.
In a greased baking dish, arrange the oysters in a single layer. Spoon the sautéed spinach mixture evenly over the oysters, then pour the creamy cheese sauce over everything. Finally, sprinkle 1 cup of breadcrumbs on top.
Preheat your oven to 375°F (190°C) and bake for 20-25 minutes until the top is golden brown and the sauce is bubbly. Let it rest for about 5 minutes before serving.
