  • Total Time: 1 hour 5 minutes
  • Yield: 8 servings 1x

Ingredients

Scale
  • 12 lasagna noodles
  • 1 lb shrimp, peeled and deveined, chopped into bite-sized pieces
  • 1 lb lump crab meat (fresh or canned, drained and picked over for shells)
  • 3 cups ricotta cheese
  • 2 cups shredded mozzarella cheese, divided
  • 1 cup grated Parmesan cheese, divided
  • 3 cups Alfredo sauce (store-bought or homemade)
  • 2 cloves garlic, minced
  • 2 tbsp olive oil
  • 1 tbsp fresh parsley, chopped (plus more for garnish)
  • Salt and pepper, to taste
  • Optional: 1/2 tsp Old Bay seasoning for extra seafood flavor

Instructions

  1. Bring a large pot of salted water to a boil. Cook lasagna noodles according to package instructions until al dente. Drain and lay flat on parchment paper or lightly oiled foil.
  2. In a skillet, heat olive oil over medium heat. Add garlic and cook for 1 minute. Add shrimp, season with salt, pepper, and Old Bay. Cook 2–3 minutes until pink. Remove from heat.
  3. In a bowl, mix ricotta cheese, 1/2 cup Parmesan, chopped parsley, salt, and pepper.
  4. Preheat oven to 375°F (190°C). Spread 1/2 cup Alfredo on bottom of a 9×13” baking dish. Add 4 noodles. Layer 1/3 of ricotta mix, shrimp, crab, drizzle with Alfredo, sprinkle mozzarella. Repeat two more layers. Top with final noodles, sauce, mozzarella, and Parmesan.
  5. Cover with foil sprayed with nonstick spray. Bake 25 minutes. Uncover and bake 15 minutes until golden and bubbly.
  6. Let rest 10 minutes before slicing. Garnish with parsley and serve.

Notes

  • Don’t overcook shrimp in the skillet—they’ll continue cooking in the oven.
  • Use a high-quality Alfredo sauce or homemade for richer flavor.
  • Fresh parsley is preferred, but dried works in a pinch.
