Tips & Variations

  • For a richer sauce, substitute half the milk with additional heavy cream.
  • Add a pinch of cayenne pepper or smoked paprika for a subtle spicy kick.
  • Top with panko breadcrumbs for a crispier crust.

Storage

Store leftover crab au gratin in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven at 325°F (160°C) until warmed through to maintain the creamy texture and avoid overcooking the crab.

Garnish

Instructions

  1. Preheat Oven: Begin by preheating your oven to 375°F (190°C) to prepare for baking the crab au gratin.
  2. Prepare Crab: Carefully inspect the jumbo lump crab meat for any stray shells and set the meat aside for use in the recipe.
  3. Make the Roux: In a medium saucepan, melt the unsalted butter over medium heat. Add the all-purpose flour and whisk continuously for about 1 minute until the mixture turns golden and forms a smooth paste.

  9. Prepare Topping: In a small bowl, combine the remaining ¼ cup of shredded cheddar cheese with the ½ cup of breadcrumbs. Sprinkle this mixture evenly over the surface of the crab mixture in the baking dish.
  10. Bake: Place the dish in the preheated oven and bake for 25 to 30 minutes, or until the topping is golden brown and bubbly, indicating the dish is cooked through.
  11. Garnish and Serve: Remove the au gratin from the oven, garnish with the freshly chopped parsley, and serve hot as a luxurious starter or main dish.

Notes

  • Be careful to pick through the crab meat for shells to ensure a pleasant eating experience.
  • The Dijon mustard and Worcestershire sauce add depth to the cheesy sauce but can be adjusted to taste or omitted for a milder flavor.
  • For a gluten-free version, substitute all-purpose flour and breadcrumbs with gluten-free alternatives.
  • The dish is best served immediately while hot and bubbly for optimal texture and flavor.
  • Leftovers can be refrigerated and gently reheated, though the topping may lose some crispiness.
