1-First Step: Preheat Oven and Prepare the Baking Surface
Set your oven to 400°F (or 425°F for fresh oysters in shell). For canned oysters, grease two 6-ounce ramekins lightly to prevent sticking. If using fresh oysters, prepare a rimmed baking sheet by spreading a bed of kosher salt or rock salt; this will stabilize oysters during baking.

2-Second Step: Clean and Prepare the Oysters
If using canned oysters, drain them and place in a small bowl. For fresh oysters, carefully shuck them, retaining their liquor to keep moisture and flavor. Place fresh oysters securely onto the salt bed or over uncooked rice to prevent tipping.

3-Third Step: Mix the Herbed Butter Mixture
In a mixing bowl, combine melted butter or prepared herb butter made by melting butter with minced shallots, fresh basil, parsley, and lemon zest with minced garlic, Cajun seasoning, and cracked black pepper. Stir to blend flavors evenly.

4-Fourth Step: Combine Breadcrumb Topping
Toast panko breadcrumbs lightly in a skillet with garlic and lemon zest for extra crunch and aroma. Once toasted, combine them with shredded Parmesan, minced parsley, and fresh thyme in a bowl. Mix well.

5-Fifth Step: Assemble the Oysters
Spoon the herbed butter mixture evenly over the oysters, ensuring thorough coverage. Next, generously sprinkle the breadcrumb mixture atop each oyster. For extra richness and texture, add optional chopped prosciutto or cooked bacon bits on top of the breadcrumbs.

6-Sixth Step: Bake the Oysters
Place the oysters in the preheated oven and bake for about 10 minutes. Baking times may vary if using fresh oysters expect 8 to 14 minutes until oysters are heated through and the breadcrumb topping achieves a golden brown color.

7-Final Step: Serve with Fresh Garnishes
Remove from the oven, season with additional salt if desired, and garnish with fresh parsley and lemon wedges. For guests who enjoy heat, serve hot sauce on the side. Serve immediately for the best texture and flavor.
