Ingredients for Grilled Oysters with Fennel Butter
Oysters: Fresh, in-shell oysters provide the base for this dish, offering a briny and slightly sweet flavor.
Butter: Softened butter acts as the creamy base for the fennel mixture, enhancing the overall richness.
Fennel: Finely chopped fennel adds a subtle sweetness and anise-like flavor that complements the oysters.
Garlic: Minced garlic introduces a pungent, aromatic element to the fennel butter.

Technique Tip for This Recipe
When preparing fennel for the fennel butter, make sure to finely chop it to ensure even distribution throughout the butter mixture. This will help the flavors meld together more harmoniously and provide a consistent taste in every bite of the grilled oysters. Additionally, when shucking the oysters, be careful to retain as much of the natural liquor as possible, as it adds a briny depth to the final dish.

How to Store or Freeze This Dish
Allow the grilled oysters to cool to room temperature before storing. This prevents condensation from forming, which can make them soggy.
Place the oysters in an airtight container. If you have multiple layers, separate them with parchment paper to avoid sticking.
Store the container in the refrigerator. Grilled oysters can be kept in the fridge for up to 2 days. Beyond this, the texture and flavor may degrade.
For freezing, arrange the oysters on a baking sheet in a single layer. This prevents them from sticking together when frozen.
Place the baking sheet in the freezer for about 1-2 hours, or until the oysters are solid.
Transfer the frozen oysters to a freezer-safe bag or container. Label with the date to keep track of freshness.
Frozen grilled oysters can be stored for up to 3 months. For best results, consume them within this timeframe.
To reheat, preheat your oven to 375°F (190°C). Place the oysters on a baking sheet and cover with aluminum foil to prevent drying out.
Heat in the oven for about 10-15 minutes, or until warmed through. Alternatively, you can reheat them on the grill over medium heat for a few minutes.
