Ingredients

For the Oysters:

  • Fresh Oysters: 12 to 16 fresh oysters on the half shell.
  • Rock Salt or Coarse Salt: 2–3 cups (for stabilizing the oysters on the baking sheet).

For the Garlic Parmesan Butter Topping:

  • Unsalted Butter: ½ cup (1 stick) softened at room temperature.
  • Garlic: 4 cloves minced.
  • Parmesan Cheese: ½ cup freshly grated Parmesan (or Romano cheese).
  • Panko Breadcrumbs: ¼ cup for a crunchy crust.
  • Fresh Herbs: 2 tbsp finely chopped fresh parsley and 1 tsp fresh thyme leaves.
  • Lemon Juice: 1 tbsp freshly squeezed lemon juice.
  • Hot Sauce (Optional): A few drops of your favorite hot sauce for a mild kick.
  • Seasoning: ¼ tsp freshly cracked black pepper and a pinch of paprika.

Step-by-Step Instructions

  1. Prep the Baking Sheet & Oysters:
    • Preheat your oven to 425°F (220°C) or set your broiler to high.
    • Spread a thick layer of rock salt over a large baking sheet.
    • Nestled the shucked oysters on the half shell firmly into the salt layer so they stay level and don’t spill their precious briny juices.
  2. Make the Garlic Parmesan Topping:
    • In a medium bowl, combine the softened butter, minced garlic, grated Parmesan cheese, Panko breadcrumbs, chopped parsley, thyme, lemon juice, hot sauce, black pepper, and paprika.
    • Mix thoroughly with a fork until a thick, spreadable compound butter forms.
  3. Top and Bake:
    • Spoon a generous tablespoon of the garlic Parmesan butter mixture onto each oyster, spreading it evenly over the meat.
    • Bake at 425°F for 8 to 10 minutes, or broil on high for 3 to 5 minutes, until the butter is hot and bubbling and the Parmesan crust turns a light golden brown.
  4. Garnish and Serve:
    • Carefully remove the baking sheet from the oven.
    • Garnish with fresh chopped parsley and serve immediately with fresh lemon wedges for squeezing!

Chef’s Tips for Success

  • Stabilize with Salt: Setting the oysters in a bed of rock salt keeps them sitting upright, ensuring the melted garlic butter stays inside the shell rather than spilling out onto the pan.
  • Use Freshly Grated Parmesan: Pre-shredded canned cheese won’t melt into the butter as smoothly. Freshly grated Parmesan creates a beautiful, crispy golden crust.
  • Serving Suggestions: Pair with a chilled glass of dry white wine (like Sauvignon Blanc or Champagne) and warm, crusty French bread to soak up every drop of garlic butter.
