What is Crab Au Gratin?
Crab au gratin is a classic gratin dish featuring succulent crab meat baked in a creamy, cheesy sauce. The "au gratin" designation indicates the presence of a browned, crusty topping, typically achieved with breadcrumbs or a similar ingredient. This dish is known for its rich textures and flavors, combining the delicate sweetness of crab with the savory richness of the sauce and the satisfying crunch of the topping.
Ingredients You'll Need:
- For the Crab Mixture:
- 1 pound lump crab meat, picked over for shells
- 1/2 cup mayonnaise
- 1/4 cup Dijon mustard
- 2 tablespoons lemon juice
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Old Bay seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- For the Cheese Sauce:
- 1/2 cup butter
- 1/2 cup all-purpose flour
- 3 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon cayenne pepper (optional, for a touch of heat)
- 2 cups shredded Gruyere cheese
- 1 cup shredded sharp cheddar cheese
- For the Topping:
- 1/2 cup breadcrumbs
- 2 tablespoons melted butter
Step-by-Step Instructions:
-
Prepare the Crab Mixture: In a medium bowl, gently combine the crab meat, mayonnaise, Dijon mustard, lemon juice, Worcestershire sauce, Old Bay seasoning, salt, and pepper. Avoid overmixing, as this can make the crab meat mushy. Set aside.
-
Make the Cheese Sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until a smooth paste forms (this is called a roux). Gradually whisk in the milk until smooth. Bring to a simmer, stirring constantly, until the sauce thickens. Reduce heat to low and stir in the salt, pepper, and cayenne pepper (if using). Remove from heat and stir in the Gruyere and cheddar cheeses until melted and smooth.
-
Combine and Bake: Pour the cheese sauce over the crab mixture and gently stir to combine. Transfer the mixture to a greased 9x13 inch baking dish.
-
Add the Topping: In a small bowl, combine the breadcrumbs and melted butter. Sprinkle evenly over the crab mixture.
-
Bake: Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the topping is golden brown and bubbly.
-
Serve: Let the crab au gratin cool slightly before serving. It's delicious served with crusty bread to soak up the extra sauce.
Frequently Asked Questions (FAQs)
Can I use different types of cheese?
Yes! While Gruyere and cheddar are classic choices, you can experiment with other cheeses. Sharp white cheddar, Fontina, or even a blend of cheeses would work well.
Can I make this dish ahead of time?
You can assemble the crab au gratin ahead of time and refrigerate it until ready to bake. Just add about 5-10 minutes to the baking time.
What kind of crab meat should I use?
Lump crab meat is the best choice for this recipe, as it has a more delicate texture and less stringy bits. Avoid using canned crab meat, as the texture will be different.
Can I freeze crab au gratin?
While it's not ideal, you can freeze crab au gratin before baking. Thaw it completely in the refrigerator before baking, adding extra time to the baking process. The texture might be slightly altered after freezing.
How do I know if my crab is cooked?
Fresh crab meat should already be cooked. The cooking process in this recipe is primarily to heat through the crab and melt the cheese, not to cook the crab itself. If you're using crab that needs cooking, be sure to cook it completely before adding it to the mixture.
