Shuck the Oysters: Carefully shuck the fresh oysters, removing them from their shells. Reserve the shells for later use as serving vessels.
Prepare the Topping: In a skillet over medium heat, melt a couple of tablespoons of butter. Add minced garlic and sauté until fragrant, about 1-2 minutes. Then, add the finely chopped spinach and cook until it wilts and any excess moisture evaporates. Remove the skillet from the heat.
Add Bread Crumbs and Cheese: Stir in the bread crumbs and grated Parmesan cheese into the spinach mixture. Season with salt and pepper to taste. The mixture should have a texture that holds together but is not overly wet.
Top the Oysters: Place a spoonful of the spinach mixture on top of each shucked oyster.
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for a few minutes.
Arrange the Oysters: Place the prepared oysters back into their shells with the spinach mixture on top. Arrange them in the air fryer basket. You may need to cook them in batches, depending on the size of your air fryer.
Air Fry: Air fry the oysters at 375°F (190°C) for about 8-10 minutes or until the topping is golden brown and crispy, and the oysters are cooked to your desired level of doneness. Keep a close eye on them to avoid overcooking.
Serve: Once done, remove the Oysters Rockefeller from the air fryer. Garnish with lemon wedges and serve immediately while they are hot and crispy
