1. Preheat your grill to medium-high heat, aiming for around 400°F. If you’re using a charcoal grill, wait until the coals are glowing red with a light coating of ash.
2. In a small bowl, combine the softened butter, minced garlic, lemon zest, parsley, black pepper, and smoked paprika (if using). Mix well until everything is evenly incorporated. This garlicky butter will be the secret to the oysters’ irresistible flavor.
3. Carefully shuck the oysters, keeping as much of the oyster liquor (juice) in the shell as possible. If you’re not comfortable shucking, many seafood markets can do this for you, or you can buy pre-shucked oysters on the half shell.
4. Place the oysters on a sturdy baking sheet or tray to keep them steady. Spoon about a teaspoon of the garlic butter mixture onto each oyster, then sprinkle generously with grated Parmesan cheese.
5. Transfer the oysters directly onto the grill, shell side down. Close the grill lid and cook for about 5-7 minutes. You’re looking for the cheese to melt and develop a light golden crust, and for the oyster edges to just start to curl.
6. Use tongs to carefully remove the oysters from the grill. Let them cool for a minute or two—these are meant to be savored slowly, not rushed!
7. Serve immediately with fresh lemon wedges for squeezing over the top. The brightness of lemon juice complements the rich, buttery topping beautifully.

One tip I picked up early on is to keep a damp towel handy when shucking oysters—it helps prevent shell fragments from scattering and keeps your hands safe. Also, don’t overcook the oysters; they should be just heated through with a lightly browned topping, not rubbery. This balance is what makes the dish sing.
