Ingredients
- 300g fresh crab meat (lump or claw meat, picked clean)
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk (warmed)
- 1/4 cup heavy cream
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon lemon juice
- 1 teaspoon Dijon mustard
- 1/4 teaspoon cayenne pepper (optional, for subtle heat)
- 1/2 cup grated Gruyère cheese
- 1/4 cup grated Parmesan cheese
- 1/2 cup plain breadcrumbs
- Salt and freshly ground black pepper to taste
- 2 tablespoons chopped fresh parsley (for garnish)
Equipment
- Oven-safe gratin dish (approximately 8-inch square or equivalent)
- Medium saucepan
- Whisk</
- Wooden spoon or spatula
- Mixing bowl
- Knife and chopping board
- Measuring cups and spoons
- Grater for cheese
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease your gratin dish with butter or non-stick spray.
- Sauté aromatics: In a medium saucepan, melt the butter over medium heat. Add the finely chopped onion and cook until soft and translucent, about 4-5 minutes. Stir in the minced garlic and cook for another minute until fragrant.
- Make the béchamel sauce: Sprinkle the flour over the butter, onion, and garlic mixture. Whisk constantly for about 2 minutes, cooking out the raw flour taste without letting it brown.
- Slowly add the warm milk: Continue whisking as you pour the milk in gradually to avoid lumps. Cook the sauce, stirring frequently until it thickens and coats the back of a spoon, around 5-7 minutes.
- Add cream and seasonings: Stir in the heavy cream, Dijon mustard, lemon juice, cayenne pepper (if using), salt, and freshly ground black pepper. Taste and adjust seasoning as needed.
- Combine crab meat: Gently fold the fresh crab meat into the béchamel sauce, being careful not to break up the lumps too much. You want those delightful chunks of crab in every bite.
- Assemble the gratin: Pour the crab mixture into your prepared gratin dish, spreading it evenly.
- Prepare the topping: In a small bowl, mix together the breadcrumbs, grated Gruyère, and Parmesan cheese. Sprinkle this mixture evenly over the crab filling.
- Bake: Place the gratin dish in the preheated oven and bake for 20-25 minutes or until the top is golden brown and bubbling.
- Garnish and serve: Remove from the oven and let cool slightly. Sprinkle with chopped fresh parsley before serving.
Tips & Variations
For the best flavor and texture, use fresh crab meat. If using canned crab, drain it well and be gentle when folding it into the sauce.
To add extra depth, a splash of white wine can be added to the béchamel sauce after cooking the flour, before adding the milk. Let it simmer until the wine reduces by half.
If you prefer a lighter version, substitute half the butter with olive oil, and use low-fat milk or cream alternatives.
For a spicy kick, add a pinch of smoked paprika or a dash of hot sauce to the filling.
Try topping the gratin with panko breadcrumbs instead of plain breadcrumbs for a crunchier crust.
