Main Ingredients

Method

Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 375°F (190°C) to ensure it’s ready for baking the au gratin.

  2. 2

    Prepare the Cream Sauce

    In a medium saucepan over medium heat, melt the butter. Add minced garlic and sauté for about 1 minute until fragrant.

  3. 3

    Create a Roux

    Whisk in the flour and cook for 2-3 minutes, stirring constantly until it forms a light blonde roux.

  4. 4

    Add Cream

    Gradually whisk in the heavy cream, ensuring there are no lumps. Continue cooking while whisking until the sauce thickens, about 5-7 minutes.

  5. 5

    Season the Sauce

    Stir in salt, black pepper, and Old Bay seasoning. Mix well to combine.

  6. 6

    Incorporate Crab and Green Onions

    Gently fold in the jumbo lump crabmeat and chopped green onions into the cream sauce. Be careful not to break apart the crabmeat too much.

Assembly and Baking

  1. 7

    Prepare Baking Dish

    Lightly grease a baking dish (about 9x9 inches) with butter or cooking spray.

  2. 8

    Layer the Crab Mixture

    Pour the crab and cream mixture into the prepared baking dish, spreading it evenly.

  3. 9

    Add Cheese Topping

    Sprinkle the shredded cheddar cheese evenly over the top of the crab mixture.

  4. 10

    Bake

    Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the cheese is bubbly and golden brown.

  5. 11

    Cool and Serve

    Remove from the oven and let it cool for a few minutes before serving. Enjoy your delicious crab au gratin!
