A lobster roll is a simple Atlantic Canadian sandwich that lets sweet, tender lobster stay in the foreground. On Prince Edward Island, a common cold style tosses bite-sized cooked lobster with a little mayonnaise, celery and lemon, then tucks it into a soft bun. Some cooks toast the roll; others serve it fresh and soft. This version warms the cut sides in butter and keeps the filling chilled and lightly dressed.
Prince Edward Island lobster rolls are not governed by one fixed formula. A widely described local version combines cooked lobster meat with mayonnaise, finely diced celery, lemon and a little seasoning. Butter-dressed rolls are also found around Atlantic Canada. Here, butter crisps the bun rather than weighing down the filling, so the lobster remains the main flavour. Use large, distinct pieces of chilled lobster instead of shredding the meat.
Keep the lobster coldKeep cooked lobster meat refrigerated at or below 4°C until you are ready to use it. If frozen, thaw it in the refrigerator, then drain well. Pat it dry and cut it into bite-sized pieces, leaving a few larger chunks for texture.
Mix the dressingIn a bowl, gently stir together the mayonnaise, celery, lemon juice, chives, salt and black pepper. Fold in the lobster just until lightly coated. Do not mash or shred the meat. Refrigerate the filling while you toast the rolls.
Prepare the rollsSplit each roll along the top without cutting all the way through. Warm a skillet or griddle over medium heat. Spread a thin layer of butter on the cut sides and toast for about 1–2 minutes, until golden and warm but still soft.
Fill and serveDivide the cold lobster mixture evenly among the four warm rolls, mounding it gently. Serve immediately while the bread is warm and the filling is cold.
If starting with raw lobsterCook the shellfish to 74°C, then cool it promptly in a shallow container in the refrigerator before removing the meat. Use clean hands and utensils, and keep raw shellfish separate from ready-to-eat foods.
Handle leftovers safelyDo not leave the filling or assembled rolls at room temperature for more than 2 hours. Refrigerate leftover filling promptly in a covered container and use within 2 days. If reheating leftover lobster for a hot filling, heat it to 74°C and do not repeatedly warm and cool it.
Make ahead: The lobster can be cooked, picked and chilled in advance. Mix the filling shortly before serving, and toast the rolls at the last minute. Thaw frozen lobster in the refrigerator, never on the counter.
Storage: Keep the lobster mixture covered at or below 4°C and use within 2 days. Refrigerate leftovers within 2 hours. The rolls are best assembled fresh; if already filled, refrigerate promptly and reheat the lobster mixture to 74°C before serving hot.
Serving: Serve with a crisp green salad, kettle chips or a simple dill pickle. Keep sides light so the sweet lobster remains central.
Rounded ingredient-based estimate per roll using cooked lobster, one soft bun, mayonnaise, butter and a share of the celery, lemon, chives and salt. Lobster sodium and bun and mayonnaise labels vary, so values are approximate rather than laboratory analysis or package-label information.
Lobster is a crustacean shellfish allergen. Mayonnaise contains egg; the roll contains wheat, and butter contains milk. Check labels for soy, sesame and cross-contact. Keep cooked lobster cold, wash hands and utensils, and separate raw shellfish from ready-to-eat foods. If cooking raw lobster, reach 74°C. Discard perishable food left out for more than 2 hours.
This Prince Edward Island–style version is served cold in a warm, lightly butter-toasted roll. Some Atlantic Canadian versions use warm lobster and melted butter.
Yes. Thaw it in the refrigerator, drain it thoroughly and keep it cold until mixing.
Yes, but this recipe assumes cooked meat. If you start with raw lobster, cook the shellfish to 74°C and cool it promptly in the refrigerator before picking the meat.
