Equipment
- 1 Air fryer
- 1 Østerskniv
- 1 Bowl
- 1 Cutting board
- 1 Knife
Ingredients
Oysters
- 16 pcs fresh oysters in shell Preferably Limfjord oysters or Gillardeau
Gratin topping
- 50 g butter Soft, at room temperature
- 2 clove garlic Finely chopped
- 2 tbsp fresh parsley Finely chopped
- 1 tbsp lemon juice
- 30 g panko breadcrumbs
40 g parmesan Freshly grated- 1 pinch cayenne pepper
- 1 tsp salt and pepper To taste
Serving
- 4 pcs lemon in wedges
- 4 slice sourdough bread For toasting alongside
Instructions
Preparation
- Preheat the airfryer to 200 °C convection.
- Open 16 pcs. fresh oysters in shell with an oyster knife — or ask the fishmonger to do it for you. Detach the oyster from the muscle and let it rest loosely in the deep half-shell with all the liquid preserved.
- Beat 50 g butter until creamy in a bowl and mix thoroughly with 2 clove garlic, 2 tbsp fresh parsley, 1 tbsp lemon juice, 30 g panko breadcrumbs, 40 g parmesan, 1 pinch cayenne pepper and 1 tsp salt and pepper, until you have a uniform, spreadable gratin paste.
- Distribute the topping evenly over each oyster, so that all the meat and liquid are covered.
Cooking in airfryer
- Place a thick layer of coarse salt or crumpled aluminium foil in the bottom of the airfryer basket. This keeps the curved oyster shells stable upright, so the butter doesn't run out during cooking.
- Place 6-8 oysters at a time in the basket with good spacing. Cook at 200 °C convection for 3-5 minutes, until the top is golden and crispy. Keep an eye from minute 3, as panko can burn quickly.
- Carefully remove the oysters with tongs and repeat the process with the remaining oysters.
Serving
- Serve immediately, while the oysters are hot and crispy, with 4 pcs lemon in wedges to squeeze over and 4 slice sourdough bread toasted crispy alongside to soak up the butter.
Notes
Tips for perfect results:
Use coarse sea salt or crumpled aluminium foil in the airfryer basket to keep the curved oyster shells stable during cooking — otherwise you risk the butter running out and the oyster drying out. The liquid in the shell is essential for the flavour. Variation:
Replace panko with extra freshly grated parmesan for a gluten-free version. You can also add finely chopped bacon or pancetta to the topping for a smoky depth, or swap the cayenne pepper for a dash of Tabasco for extra heat. Serving:
Serve with cold, dry white wine (Chablis, Muscadet or Sancerre) or a glass of champagne. Toasted sourdough bread is mandatory — the buttery gratin topping is too good not to be soaked up. Cooked rather than raw:
If you find raw oysters challenging in terms of taste or texture, gratinated oysters are the perfect introduction. The heat removes the glassy, jelly-like texture and brings out the natural sweetness, while butter, garlic and parmesan make the flavour richer and more familiar. Portion size:
If your airfryer is smaller, you can cook the oysters in 2-3 batches. Keep finished oysters warm on a warm plate under a dish, while you cook the rest.
