Malpeque oysters are a Prince Edward Island favourite, and this baked version follows the simple Island pattern published by Canada’s Food Island: celery, onion, hard-boiled egg, toasted crumbs, parsley and oyster liquor. It is one documented preparation, not a universal formula. The light topping leaves the oyster flavour at the centre.
The oysters are shucked and returned to clean lower shells before baking. For this half-shell preparation, bake at 230°C for at least 10 minutes and cook shellfish to 74°C; check the flesh with a clean thermometer where it can be positioned safely.
Heat the oven and prepare the panHeat the oven to 230°C with a rack in the middle. Line a rimmed baking sheet with crumpled foil to support the shells, or set them in an even bed of coarse salt.
Scrub and shuckScrub live oysters under cold running water just before use. Discard cracked oysters and any that stay open after tapping. Protect your shucking hand with an oyster glove or folded towel. Open each oyster over a clean bowl; strain the liquor through a fine sieve and keep it and the oyster meat chilled.
Make the toppingHard-boil, cool, peel and grate the eggs. Melt the butter in a pan over medium heat. Add celery and onion and cook, stirring, for 8–10 minutes until soft. Stir in breadcrumbs and toast lightly for 2 minutes. Remove from the heat and fold in egg and parsley. Add strained oyster liquor a little at a time until the mixture is moist but still holds on a spoon. Season lightly.
Fill the shellsArrange clean lower shells on the prepared pan. Put one raw oyster into each shell and divide the topping over them without packing it tightly.
Bake safelyBake at 230°C for at least 10 minutes. Where a clean thermometer can be positioned safely, check that oyster flesh reaches 74°C. Do not serve oysters that miss the safe endpoint.
ServeCarefully transfer the hot shells to a heatproof platter and serve immediately. Keep plates and tools used for raw oysters separate from cooked oysters.
Keep live oysters refrigerated below 4°C in an open tray that catches drips, covered with a damp cloth; do not submerge or seal them. Buy from a reputable retailer and keep the shellfish shipper tag until the meal is finished. Shuck just before cooking. Wash hands with soap for 20 seconds and clean and sanitize the knife, bowl, pan and work surface after handling raw oysters. Serve promptly; refrigerate leftovers within 2 hours and reheat to 74°C.
Rounded estimate from ingredient-composition data. Oyster size, butter salinity and breadcrumb labels vary; this is not laboratory analysis.
Contains oysters (molluscs), milk from butter and egg; breadcrumbs may contain wheat or gluten, so check labels. Buy shellfish from a reputable retailer and keep the shipper tag. Refrigerate live oysters below 4°C, prevent raw juices from contacting ready-to-eat food, and clean hands and tools after shucking. For these shucked half-shell oysters, bake at 230°C for at least 10 minutes and cook the shellfish to 74°C. People at higher risk of foodborne illness should avoid raw or undercooked shellfish. Cooking cannot make oysters from a closed harvest area safe.
No. Health Canada’s current guidance for oysters baked in the shell is at least 10 minutes at 230°C. Follow that time and check 74°C where possible.
