Indulge in the luxurious flavors of this creamy, cheesy lump crab mornay — a French-inspired seafood delight perfect for special occasions or upscale dinners at home.

🛒 Ingredients (Servings: 4)

• 1 lb lump crab meat (picked over for shells)
• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk
• ½ cup heavy cream
• 1½ cups grated Gruyère cheese (or Swiss cheese)
• ¼ teaspoon Dijon mustard
• 1 tablespoon dry sherry (optional)
• ½ teaspoon kosher salt
• ¼ teaspoon freshly ground black pepper
• Pinch of cayenne pepper (optional)
• 1 tablespoon chopped fresh parsley (for garnish)
• Toast points or puff pastry shells, for serving

🍳 Instructions:

1️⃣ Make the Roux:
🧈 In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for about 1 minute, creating a smooth roux without browning it.

2️⃣ Add the Milk and Cream:
🥛 Slowly whisk in the milk and heavy cream. Cook, whisking constantly, until the mixture thickens—about 3–4 minutes.

3️⃣ Melt the Cheese:
🧀 Reduce the heat to low and stir in the grated Gruyère cheese, Dijon mustard, and sherry (if using). Stir until cheese is fully melted and the sauce is smooth.

4️⃣ Season and Add Crab:
🧂 Add salt, pepper, and cayenne (if using). Gently fold in the lump crab meat, being careful not to break it up too much. Cook just until heated through.

5️⃣ Serve:
🍽 Spoon the warm crab Mornay over toast points or into puff pastry shells. Garnish with chopped parsley and serve immediately.
