You can find out more about making conscious seafood choices from groups like the Marine Stewardship Council.

• 1 tsp Dijon mustard
• A pinch of nutmeg
• Salt and freshly ground black pepper

Step-by-Step Instructions: Crafting Your Perfect Seafood Lasagna

Right, let’s get down to the cooking! By following these steps with care, you are on the path to a truly spectacular dish. We find it helpful to read through the entire method once before you start.

Step 1: Prepare the Seafood

1. First, let’s get the seafood ready. If your prawns are on the larger side, feel free to chop them into more manageable, bite-sized pieces. Pat them thoroughly dry with a paper towel.
2. Warm the olive oil in a large frying pan over a medium heat. Add the minced garlic and sauté for 30 seconds or so until it becomes aromatic, taking care that it doesn’t brown.
3. Introduce the prawns to the pan and cook for just 2-3 minutes, until they turn a lovely pink. It’s important not to cook them completely, as they’ll finish cooking in the oven.
4. Using a slotted spoon, transfer the prawns to a bowl and set them aside. To the same bowl, gently mix in the cooked crab meat.

Step 2: Create the Creamy White Sauce

The foundation of this dish is its beautiful white sauce seafood lasagna. Give it your patience and attention, and you will be rewarded with a flawlessly smooth, silky texture.

1. Using the same pan, melt the butter and add the finely chopped onion. Cook gently over a medium-low heat for 5-7 minutes, until the onion has softened and become translucent.
2. Increase the heat, pour in the white wine, and allow it to bubble for a minute or two, letting the alcohol cook away until the liquid has reduced by about half.
3. Reduce the heat back to low. Sprinkle the flour into the pan and stir it in continuously for 2 minutes. This cooks out the raw taste of the flour and creates a ‘roux’.
4. Begin to add the warm milk gradually, pouring in a small amount at a time while whisking constantly. Adding the milk slowly is the key to preventing any lumps. Continue whisking until all the milk has been incorporated and the sauce is perfectly smooth.
5. Allow the sauce to simmer gently for 5-8 minutes, stirring now and then, until it has thickened to a consistency that nicely coats the back of a spoon.
6. Take the sauce off the heat. Stir through the Dijon mustard, the pinch of nutmeg, most of the chopped parsley (saving a little for the garnish), and season generously with salt and pepper. Give it a taste and adjust if necessary.

Step 3: Assemble Your Masterpiece

Now it’s time to bring all the elements together! You will need a large rectangular baking dish (roughly 20cm x 30cm).

1. To begin, spread a thin layer of the white sauce across the bottom of your baking dish. This creates a base and stops the pasta from sticking.
2. Place a single layer of lasagna sheets over the sauce. If you are not using no-cook sheets, please ensure they are pre-cooked as per the packet directions.
3. Evenly spread about a third of the remaining white sauce over the pasta.
4. Distribute half of the prawn and crab mixture evenly across the sauce.
5. Sprinkle over a third of the grated mozzarella and Parmesan.
6. Repeat this layering process: a layer of pasta, followed by sauce, the rest of the seafood mixture, and another third of the cheese.
7. Add a final layer of pasta sheets. Top with the last of the white sauce, ensuring the pasta is completely covered to keep it from drying out, and finish with the remaining mozzarella and Parmesan.

Step 4: Bake to Golden Perfection

1. Preheat your oven to 180°C (160°C Fan / Gas Mark 4).
2. Set the lasagna dish on a baking tray; this will catch any sauce that might bubble over.
3. Bake in the preheated oven for 35-45 minutes. It’s ready when the top is golden-brown and bubbling, and you can see the sauce simmering at the sides.
4. Once baked, take the lasagna out of the oven and allow it to rest for a minimum of 10-15 minutes. This resting period is crucial! It helps the layers to settle, which makes for cleaner, neater slices when serving.
5. Just before serving, garnish with your reserved fresh parsley.

Top Tips for the Best Seafood Lasagna Recipe

To help you achieve perfection, we’ve compiled some of our favourite pointers to guarantee success and help you create the best seafood lasagna recipe you can.

• Gentle Cooking for Seafood: Do not forget that the prawns and crab will have more cooking time in the oven. A brief initial sauté is all they require.
• Fresh is Ideal, But Frozen is Fine: If fresh prawns are unavailable, good-quality frozen raw prawns make an excellent alternative. Simply ensure they are fully defrosted and patted very dry before you cook them.
• The Perfect Sauce Consistency: Your béchamel needs to be thick enough to coat the pasta layers but remain pourable. If it seems too thick, whisk in a little more warm milk. If too thin, let it simmer for a few more minutes to reduce.
• The Importance of Resting: We cannot say this enough. Allowing the lasagna to stand before you slice it is what stops it from becoming a liquid mess on the plate. A little patience goes a long way!
• Prepare your shrimp perfectly: Getting the best out of your shrimp is crucial. For more ideas on handling this wonderful ingredient, you might also enjoy The Ultimate Crispy Baked Shrimp Recipe.

Customising Your Seafood Lasagna

The beauty of home cooking lies in the freedom to adapt a recipe to your own tastes. Here are some suggestions for personalising your creamy seafood lasagna:

• Introduce Scallops for Extra Luxury: For an even more decadent meal, try adding some small, seared bay scallops into the seafood mix.
• Weave in Some Greens: A layer of wilted spinach or gently sautéed leeks will introduce another layer of flavour and a lovely touch of colour. Just be sure to squeeze out all excess liquid first.
• A Touch of Warmth: A small pinch of red pepper flakes or a little cayenne pepper added to the white sauce will provide a subtle, warming heat.
• Experiment with Cheeses: Don’t hesitate to try different cheeses. A little Gruyère or Fontina grated in with the mozzarella adds a wonderful, nutty depth.
• Make Use of Leftovers: If you happen to have some leftover crab meat from making our Tasty Louisiana Crab Cakes, this is the perfect way to use it!

Frequently Asked Questions (FAQ)

Can I make this ahead of time?

Of course. This recipe is wonderfully convenient for preparing in advance. You can assemble the entire lasagna (before the baking stage), cover it well with cling film, and keep it in the refrigerator for up to 24 hours. When you are ready to cook, it may require an extra 10-15 minutes in the oven as it will be baking from cold.

Can I freeze seafood lasagna?

It certainly does. This dish freezes beautifully, either baked or unbaked. For the best results, wrap the dish tightly in a double layer of cling film and then a layer of foil. It can be stored in the freezer for up to 3 months. Let it thaw completely in the fridge overnight before baking as per the instructions.

What kind of crab meat is best?

We find that good-quality lump crab meat, which you can typically find in tubs in the chilled aisle of the supermarket, works best. Using a combination of delicate white meat and flavourful brown meat gives a fantastic depth. Tinned crab meat can also be used if fresh is not available.

What should I serve with this dish?

This wonderfully rich lasagna is best complemented by simple side dishes. We love to serve it with a crisp green salad tossed in a sharp vinaigrette to balance the creaminess, or perhaps some steamed asparagus or green beans with a squeeze of fresh lemon juice.
