Instructions
Preheat your oven to 375°F (190°C). Grease a baking dish with butter.
In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1-2 minutes, stirring constantly to avoid burning.
Gradually whisk in the milk and heavy cream, continuing to stir until the sauce thickens, about 5 minutes.
Remove the saucepan from heat. Stir in half of the Gruyère cheese, all of the Parmesan cheese, parsley, lemon juice, Old Bay seasoning, salt, and pepper until the cheese is melted and the sauce is smooth.
Gently fold in the crabmeat, being careful not to break up the lumps.
Pour the crab mixture into the prepared baking dish. Sprinkle the remaining Gruyère cheese on top.
Bake for 20-25 minutes, or until the top is golden and bubbly.
Remove from the oven and let it rest for 5 minutes before serving. Garnish with additional parsley.
