Mozzarella is my personal favorite cheese in this because it creates such gorgeous pulling strands with every serving It reminds me of special Sundays in my childhood when my dad would always sneak a little extra cheese on top for that golden brown finish That memory makes this dish extra special at my table

Storage Tips

Refrigerate leftovers in an airtight container Keep it chilled and it stays delicious for up to three days The lasagna texture holds best when you reheat slower in the oven

Ingredient Substitutions

If you cannot find a seafood blend try all shrimp or all scallops Or add some cooked white crab for a touch of sweetness Spinach or thinly sliced zucchini work well if you want to sneak in extra vegetables Ricotta can be swapped for cottage cheese for a lighter option

Serving Suggestions

Serve with a simple green salad with a sharp lemon vinaigrette The acidity cuts through the richness and brightens every bite Garlic bread or even herby roasted potatoes on the side make it a fully satisfying meal

Seasonal Adaptations

In spring or summer use more fresh herbs such as dill and basil for a lighter touch Winter months are perfect for a slightly heavier cheese layer and a dash of nutmeg in the béchamel Swap seafood for cooked seasonal fish from your market for a fantastic twist

→ Lasagna Assembly

16 8 ounces fresh lasagna noodles
17 1/2 cup shredded mozzarella cheese

Preparation Steps

Step 01

Preheat oven to 350°F. Thoroughly grease a 9 x 13-inch baking dish with butter or non-stick spray. Set aside.

Step 02

Melt butter in a saucepan over medium heat. Stir in flour and cook, stirring constantly, for 1 minute until slightly toasted. Gradually whisk in milk, continuing to stir until sauce thickens, about 3–5 minutes. Remove from heat and stir in parmesan cheese and salt until smooth.

Step 03

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

Step 04

Heat olive oil in a skillet over medium heat. Add seafood mix, salt, black pepper, and parsley. Sauté for about 3 minutes until seafood is just cooked through, then remove from heat.

Step 05

Spread a thin layer of béchamel sauce on the bottom of the greased baking dish. Arrange a layer of lasagna noodles over the sauce. Top with one-third of ricotta mixture, followed by one-third of the seafood, and one-third of remaining béchamel sauce. Repeat to form three complete layers, finishing with remaining noodles, béchamel sauce, and top with shredded mozzarella.

Step 06

Cover the baking dish loosely with aluminum foil. Bake in preheated oven for 35 minutes or until bubbling and cheese is fully melted. Remove foil if needed to brown the top in the final minutes.

Step 07

Remove from oven and let lasagna rest for at least 10 minutes before slicing. Serve hot for best results.

Additional Suggestions

  1. Allowing the baked lasagna to rest improves slicing and presentation by helping layers to set.
  2. If using frozen seafood, ensure it is fully thawed and patted dry before sautéing to avoid excess moisture.
  3. Adjust salt and pepper in the béchamel and filling to taste for balanced seasoning.
