1.Bring a large stockpot of heavily salted water to a rolling boil.2.Add the live lobsters, cover, and cook for 8-10 minutes until bright red.3.Transfer to an ice bath to stop the cooking, then drain.4.Crack shells and remove all meat from claws, knuckles, and tails.5.Chop lobster meat into generous bite-sized chunks.TIPReserve the shells to make lobster stock for another use — they freeze well. - saute · ~6 min
Make the cream sauce base.
1.Melt 3 tablespoons of butter in a medium saucepan over medium heat.2.Whisk in the flour and cook, stirring constantly, for 1-2 minutes until it smells nutty but not brown.3.Gradually pour in the milk and cream, whisking continuously.4.Bring to a gentle simmer and cook until thickened, about 3-4 minutes.TIPDon't let the roux get too dark — a pale golden color keeps the lobster flavor front and center. - mix · ~1 min
Finish the sauce.
Remove the pan from heat. Stir in the sherry, lemon juice, tarragon, paprika, nutmeg, a pinch of salt, and the black pepper. Taste and adjust seasoning.
- assemble · ~2 min
Assemble the casserole.

Bake until golden and bubbly.
Place the dish in the preheated oven and bake for 20-25 minutes, until the sauce bubbles around the edges and the topping is deeply golden and crisp.
TIPIf the top browns too quickly, tent loosely with foil for the last 5 minutes. - rest · ~5 min
Let the casserole rest.
Remove from the oven and let it stand for 5 minutes — the sauce will set slightly and the dish will be easier to serve.

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1For the most tender lobster, drop live lobsters headfirst into boiling water and do not overcook.
- 2Grate fresh nutmeg just before using — it adds a warm, aromatic depth that pre-ground can't match.
- 3Fold the lobster gently into the sauce to keep the chunks intact and avoid shredding.
- 4Use dry sherry, not cooking sherry; the flavor is cleaner and more refined in the finished dish.
- 5Let the casserole rest 5 minutes after baking so the sauce sets slightly for cleaner serving.
- 6Crush the butter crackers into uneven crumbs — some larger pieces add texture, finer bits create a cohesive crust.
- 7Blot any excess moisture from freshly cooked or thawed lobster meat with paper towels so the sauce stays thick.
Adapt it for your goals.
Crab casserole
Substitute fresh or pasteurized lump crab meat for the lobster for a more affordable yet still luxurious twist that cooks in the same time.
gluten freeGluten-free
Replace all-purpose flour with a 1:1 gluten-free all-purpose blend (with xanthan gum) and use gluten-free butter crackers for the topping.
lighter cream sauceLighter cream sauce
Swap heavy cream for half-and-half and use 2% milk instead of whole milk for a less rich but still velvety sauce that works for a weeknight meal.
