Ingredients

24 fresh oysters, scrubbed clean
2 tbsp unsalted butter, melted
2 cloves garlic, minced
2 tbsp fresh parsley, finely chopped
1 tbsp fresh chives, finely chopped
0.5 tsp lemon zest
0.5 tsp salt
0.25 tsp black pepper
1 lemon cut into wedges, for serving

Instructions

1 Preheat your oven to 400°F (200°C) and arrange a baking sheet with a layer of coarse salt or crumpled foil to cradle the oysters, ensuring they lie flat. Carefully shuck the fresh oysters, keeping the liquor inside the shell and discarding any broken shells. Place each shucked oyster onto the prepared baking sheet.
2 In a small bowl, whisk together the melted unsalted butter, minced garlic, chopped fresh parsley, chopped fresh chives, lemon zest, salt, and black pepper until well combined. This aromatic mixture will infuse the oysters with bright flavors.
3 Spoon about a teaspoon of the herb and garlic butter mixture over each oyster, ensuring even distribution. The aroma of the garlic and herbs will start to become noticeable as you prepare them.
4 Bake the oysters in the preheated oven for 8 to 10 minutes, or until the edges of the oysters begin to curl and the butter mixture is bubbling and fragrant. The oysters should be just cooked through, maintaining a tender texture.
5 Carefully remove the baking sheet from the oven. Serve the oysters immediately while hot, accompanied by fresh lemon wedges for squeezing over the top. The briny oysters, rich butter, and fresh herbs create a delightful flavor combination.

Tips & Notes

Shuck over a bowl and hold each oyster cup-side down so the liquor stays in the shell. It seasons the oyster as it bakes.
Run the knife under each oyster to free it from the bottom shell before adding the butter, so it slides out easily when eaten.
The coarse salt or crumpled foil bed in step 1 keeps the shells level so the butter and juices don't spill in the oven.
