  • 3 tablespoons Unsalted Butter
  • 1 tablespoon Olive Oil (for sautéing spinach)
  • 3 cloves Garlic (minced)
  • 3 tablespoons All-Purpose Flour
  • 2 cups Chicken Stock (low‑sodium)
  • 1 teaspoon Creole or Cajun Seasoning (to taste)
  • 0.5 teaspoon Black Pepper (freshly cracked)
  • 1 cup Fontina Cheese (shredded)
  • 1 cup Mozzarella Cheese (shredded)
  • 9 sheets Lasagna Noodles (regular, no‑boil if preferred)
  • 1 spray Nonstick Cooking Spray (to coat baking dish)
  • 2 tablespoons Fresh Parsley (chopped, for garnish)

Instructions

  1. Season the Seafood

    Roughly chop the large shrimp into bite‑size pieces, then combine shrimp, crawfish tails, and lump crab meat in a large bowl. Toss with 2 tsp Creole seasoning, 1 Tbsp crab boil seasoning, and 2 tsp liquid crab boil. Set aside.

    Time: PT10M

  2. Prepare the Cream Cheese Filling

    In a mixing bowl, combine 8 oz garlic‑herb cream cheese, 4 oz sour cream, ½ cup shredded Parmesan, and 2 Tbsp chopped fresh basil. Mix until smooth and creamy, then set aside.

    Time: PT5M

  3. Wilt the Spinach

    Heat 1 Tbsp olive oil in the cast‑iron skillet over medium heat. Add the frozen spinach (about three 10‑oz bags) and cook, stirring, until almost all liquid evaporates and only about 2 Tbsp of moisture remain. Transfer to a bowl and set aside.

    Time: PT5M

  4. Make the Cheese Sauce (Roux)

    In the same skillet, melt 3 Tbsp unsalted butter over medium‑low heat. Add the minced garlic and sauté for about 30 seconds, being careful not to brown. Sprinkle in 3 Tbsp all‑purpose flour, stirring constantly for 1 minute to form a roux. Slowly whisk in 2 cups chicken stock, adding it in a steady stream while whisking to avoid lumps. Keep the heat medium and continue whisking until the sauce thickens, about 4‑5 minutes. Stir in 1 tsp Creole/Cajun seasoning, ½ tsp freshly cracked black pepper, and 1 cup shredded Parmesan until melted. Remove from heat.

    Time: PT12M

  5. Cook the Lasagna Noodles

    Bring a large pot of salted water to a boil, add a splash of liquid crab boil for extra flavor, and cook the lasagna noodles according to package directions until al dente. Drain in a colander and set aside.

    Time: PT10M

    Temperature: 212°F

  6. Assemble the Lasagna

    Spray a 9×13‑inch baking dish with nonstick cooking spray. Spread a thin layer of the cheese sauce on the bottom. Lay 3 lasagna noodles overlapping slightly. Spoon half of the cream‑cheese filling over the noodles and spread evenly. Distribute half of the seasoned seafood, then add the wilted spinach. Sprinkle ½ cup each of shredded Fontina and mozzarella. Drizzle a generous amount of the remaining cheese sauce. Repeat the layering two more times, ending with a top layer of sauce and the remaining Fontina and mozzarella.

    Time: PT8M

  7. Bake the Lasagna

    Place the assembled lasagna in a pre‑heated oven and bake uncovered at 375°F for 40‑45 minutes, until the sauce is bubbling and the cheese on top is golden.

    Time: PT45M

    Temperature: 375°F

  8. Broil for a Golden Top

    Remove the foil (if used) and switch the oven to broil. Position the rack in the center and broil for 5 minutes, watching closely until the cheese is beautifully browned.

    Time: PT5M

    Temperature: Broil

  9. Rest and Garnish

    Remove the lasagna from the oven and let it rest for at least 15 minutes. Sprinkle with 2 Tbsp chopped fresh parsley before serving.

    Time: PT15M

Q

What are the traditional regional variations of seafood lasagna in Italian‑American cooking?

How is authentic seafood lasagna traditionally served in Italian‑American households?

cultural
Q

What occasions or celebrations is seafood lasagna traditionally associated with in Italian‑American culture?

cultural
Q

What are the most common mistakes to avoid when making seafood lasagna?
