Step‑by‑Step Instructions for Lasagne of Crab with Beurre
Step 1: Pasta Dough Preparation
Begin by placing strong plain flour, a pinch of salt, eggs, and olive oil into a food processor. Blend until the mixture forms a consistent dough, which may take about 1–2 minutes. Once combined, wrap the dough in cling film and refrigerate for at least 1 hour to allow it to rest and become more pliable.
Step 2: Roll and Blanch Pasta
After resting, dust your countertop with flour and roll out the dough using a pasta machine, aiming for thin sheets. Cut these sheets into rectangles or squares that will fit your lasagne dish. Bring a pot of salted water to a boil and briefly blanch the pasta sheets for 30 seconds, then remove and cool on a kitchen towel.
Step 3: Make the Crab Mousse
In a chilled food processor, blend the fresh scallops until smooth, incorporating half of the double cream while seasoning with salt and pepper. Once the mixture is creamy and well combined, gently fold in the white crab meat until just mixed. Place this creamy crab mousse into metal rings or a piping bag for layering.
Step 4: Layer the Lasagne
Start assembling your lasagne by placing a sheet of pasta at the bottom of your chosen dish or metal rings. Alternately layer the sheets with the crab mousse, repeating until all ingredients are formed into layers, finishing with a pasta sheet on top. Refrigerate these assembled lasagnes for at least 30 minutes to firm up.
Step 5: Prepare the Beurre Nantais Sauce
In a saucepan over medium heat, sauté finely chopped shallots in a generous knob of unsalted butter until translucent. Next, deglaze the pan by adding white wine and wine vinegar, allowing the mixture to reduce by half. Gradually whisk in chicken stock and the remaining double cream, then remove from heat and gently blend in chilled diced butter for a smooth, emulsified sauce.
Step 6: Steam the Lasagnes
Fill your steamer with water and bring it to a gentle simmer. Place the assembled crab lasagnes in the steamer basket and cover. Steam for approximately 12 minutes, or until the pasta is tender and the mousse is heated through. The lasagnes should look plump and golden when ready to serve alongside the beurre nantais sauce.
Step 7: Garnish and Serve
Once removed from the steamer, carefully slide a sharp knife around the edges of the rings to release the lasagne. Plate each portion, drizzle the rich beurre nantais sauce over the top, and garnish with freshly chopped chives and chervil. The delicate layers of the lasagne of crab with beurre are now ready to impress your guests!

Crab Lasagne with Beurre Nantais Recipe FAQs
What type of crab meat is best to use?
Absolutely! For the best flavor and texture, I recommend using fresh white crab meat whenever possible. However, high-quality canned crab meat can also work in a pinch—just ensure it’s well-drained and doesn’t have any strong odors.
How should I store leftover crab lasagne?
To keep your exquisite lasagne fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. This prevents the pasta from drying out and maintains the integrity of the rich flavors.
Can I freeze the crab lasagne?
Very! If you’d like to prepare it in advance, you can freeze unsteamed lasagnes for up to 2 months. To do this, wrap them tightly in plastic wrap, followed by aluminum foil to avoid freezer burn. When you’re ready to enjoy, simply thaw it in the fridge overnight and steam it for about 15 minutes until heated through.
What if my crab mousse turns out grainy?
Good question! To avoid a grainy texture, ensure that you thoroughly blend the scallops in a chilled food processor. It’s vital to mix well and incorporate the cream smoothly. If the mousse does end up grainy, try adding a touch more cream and blend again until smooth.
