  • Freshly grated parmesan cheese: Gives nutty savoriness Buy a block and grate it yourself for best flavor
  • Ricotta cheese: Brings creaminess and mild tang Use a good quality brand with few ingredients
  • Mozzarella cheese: For stretch and mild richness Buy whole milk mozzarella and shred it fresh if possible
  • Large egg: Holds the ricotta filling together Fresh eggs lift the mix and give the right texture
  • Dried parsley: Herbs add color and a bit of earthiness Use dried or fresh chopped if available
  • Seafood mix: Combines tender shrimp scallops fish or whatever you like Choose fresh or properly thawed frozen mix

Instructions

Preheat the Oven:
Set your oven to 180C or 350F Grease a large baking dish well so every piece comes out clean with a golden edge
Make the Béchamel Sauce:
Warm butter in a saucepan over medium heat and gently melt it Add flour and stir constantly for about one minute until the mixture starts to smell toasty Slowly pour in milk in a steady stream while whisking nonstop to avoid lumps Cook for several minutes until the sauce thickens enough to coat the back of your spoon Stir in parmesan and a pinch of salt then take off heat
Mix the Ricotta Filling:
In a large bowl combine ricotta mozzarella beaten egg parsley and salt Mix until fluffy and evenly blended Scrape the sides well so nothing is left behind the cheese mixture should be smooth
Sauté the Seafood:
Place a skillet over medium heat Add a drizzle of olive oil When hot toss in the seafood mix with a sprinkle of salt pepper and dried parsley Stir gently for just about three minutes until the seafood turns opaque and just cooked Remove quickly to avoid overcooking this keeps it tender
Assemble the Lasagna:
Start with a thin layer of béchamel on the bottom of your baking dish so nothing sticks Lay down sheets of lasagna noodles slightly overlapping top with a third of the ricotta mixture and spread it out completely Scatter over a third of the cooked seafood then spoon over more béchamel Continue layering noodles cheese seafood and sauce until you have three layers Finish with a thick layer of béchamel and all the remaining mozzarella cheese
Bake to Perfection:
Bake the dish uncovered for about thirty five minutes Watch that the top gets golden and bubbly but not dark brown If it browns too fast drape a sheet of foil loosely over the top Let it rest for ten minutes after baking which helps the layers set and makes cutting easier
Serve and Enjoy:
Slice into generous pieces and serve hot with your favorite sides You get creamy cheesy seafood in every forkful

My favorite part is the béchamel sauce I love how its silky richness wraps around the seafood making every bite irresistible One holiday my son helped me layer the noodles and we laughed as we snuck mozzarella straight from the bowl

Storage Tips

Allow the lasagna to cool to room temperature before storing so condensation does not make it soggy Always store in a tightly sealed container in the refrigerator It keeps well for three days and flavors meld even more overnight

Ingredient Substitutions

If you do not have fresh seafood use a high quality frozen seafood mix well thawed Substitute cottage cheese for ricotta if needed or use all parmesan instead of mozzarella for a nuttier flavor For a lighter option use milk with a lower fat content or whole wheat lasagna sheets

Serving Suggestions

Serve each slice with a crisp green salad dressed with lemon or vinaigrette A warm basket of garlic bread on the side works wonders Chilled white wine or sparkling water brightens the flavors of the dish and makes your meal feel festive

Cultural and Historical Context

Seasonal Adaptations

In spring swap in peas and asparagus for a fresh layer During winter add a pinch of nutmeg to the béchamel for warmth For summer use basil leaves or fresh tomatoes between layers for extra brightness

11 1 pound seafood mix (shrimp, scallops, crab, or similar)
12 1 teaspoon olive oil
13 1/2 teaspoon kosher salt
14 1/4 teaspoon black pepper
15 1 teaspoon dried parsley

→ Assembly

16 1/2 pound fresh lasagna noodles
17 1/2 cup shredded mozzarella cheese (for topping)

Steps to Follow

Step 01

Preheat the oven to 350°F (180°C). Grease a 9 x 13-inch baking dish with butter or non-stick spray and set aside.

Step 02

In a saucepan over medium heat, melt butter. Add flour and stir constantly for about one minute until lightly golden. Gradually add milk, whisking continuously until the mixture thickens. Stir in parmesan cheese and salt, then remove from heat.

Step 03

In a mixing bowl, combine ricotta cheese, shredded mozzarella, whisked egg, dried parsley, and salt. Mix thoroughly until smooth and evenly blended.

Step 04

Heat olive oil in a skillet over medium heat. Add seafood mix, season with salt, black pepper, and dried parsley. Sauté for approximately three minutes until just cooked through. Remove from heat.

Step 05

Spread a layer of béchamel sauce on the bottom of the prepared baking dish. Lay fresh lasagna noodles over the sauce. Evenly distribute one third of the ricotta filling, one third of the seafood mixture, and one third of béchamel sauce. Repeat layering two more times, finishing with a layer of noodles, béchamel, and topping with shredded mozzarella.

Step 06

Place the assembled lasagna in the preheated oven and bake for 35 minutes, until the top is golden brown and the cheese is melted and bubbling. If browning occurs too quickly, loosely cover with aluminum foil for the remainder of the cooking time.

Step 07

Remove the lasagna from the oven and allow it to cool for at least 10 minutes before slicing. Serve portions hot for optimal texture and flavor.

Additional Tips

  1. Use freshly grated parmesan for enhanced flavor and optimal melting in the béchamel sauce.
  2. Do not overcook the seafood; sauté just until opaque to prevent rubbery texture.
  3. Let the lasagna rest before cutting to help layers set and facilitate neater portions.
  4. For best results, use fresh lasagna noodles or precook dried sheets until al dente.
  5. Assemble up to one day ahead and refrigerate until ready to bake for added convenience.
