🧀 What Makes This Seafood Lasagna So Special?

This lasagna is a showstopper—and it doesn’t rely on complicated ingredients. It’s packed with protein from shrimp and crab, richness from Alfredo and heavy cream, and just the right bite from red pepper flakes. I love how it balances creamy, cheesy layers with the bright, sweet flavor of seafood. Even better? It bakes beautifully and holds its shape for easy slicing!

🛒 Ingredients You’ll Need

🍝 Pasta

  • 12 lasagna noodles – regular or oven-ready (use whole wheat for a healthier twist)

🦐 Seafood

  • 1 lb shrimp – peeled, deveined, and chopped

  • 1 lb crab meat – lump crab or imitation crab both work

🧀 Cheeses

  • 2 cups ricotta cheese

  • 2 cups shredded mozzarella cheese

  • 1 cup grated Parmesan cheese

🥣 Sauces & Creams

  • 4 cups Alfredo sauce – homemade or high-quality store-bought

  • 1 cup heavy cream – for ultra creaminess

🧂 Seasonings

  • 2 cloves garlic, minced

  • 2 tbsp olive oil

  • 1 tbsp fresh parsley, chopped

  • 1 tsp salt

  • 1 tsp black pepper

  • ½ tsp red pepper flakes (optional for heat)

🍞 Toppings

  • ½ cup breadcrumbs – adds that perfect golden crunch

👩‍🍳 How to Make Our Creamy Seafood Lasagna

1. Prep & Cook the Pasta

Preheat oven to 375°F (190°C). Cook lasagna noodles according to package directions. Drain and lay flat to cool.

2. Sauté the Seafood

In a skillet over medium heat, warm olive oil and sauté minced garlic until fragrant (about 1 minute). Add shrimp and cook until pink and opaque (3–4 mins). Stir in crab, salt, pepper, and red pepper flakes. Cook 2–3 minutes, then remove from heat.

3. Mix the Cheese Filling

In a bowl, combine ricotta, 1 cup mozzarella, ½ cup Parmesan, heavy cream, and parsley. Mix until smooth and creamy.

4. Layer the Lasagna

Spread Alfredo sauce on the bottom of a 9×13-inch baking dish. Layer lasagna noodles, ⅓ of the cheese mixture, ⅓ of the seafood mixture, and a drizzle of Alfredo. Repeat 3 layers, ending with noodles and sauce.

5. Top & Bake

Sprinkle remaining mozzarella, Parmesan, and breadcrumbs over top. Cover with foil and bake for 25 minutes, then uncover and bake an additional 10–15 minutes until bubbly and golden.

6. Rest & Serve

Let lasagna rest for 10 minutes before slicing. Garnish with fresh parsley.

🧊 Storage & Reheating Tips

  • Fridge: Store in airtight container for up to 3 days

  • Freezer: Wrap tightly and freeze for up to 2 months (use freezer-safe dish)

💡 Kristy’s Tips & FAQs

Q: Can I use no-boil noodles?
Yes! Just increase sauce slightly and ensure they’re fully covered before baking.

Q: What kind of crab is best?
Lump crab is ideal, but imitation crab works well on a budget.

Q: Can I make it lighter?
Absolutely! Swap heavy cream with half-and-half and use part-skim cheeses.

Q: Gluten-free version?
Use GF lasagna noodles and skip the breadcrumbs or use crushed GF crackers.
