Ingredients
- 12 lasagna noodles
- 1 cup green onions (sliced)
- 2 Tablespoons garlic (minced)
- 12 ounces bay scallops (or sea scallops, chopped)
- 1 pound raw medium shrimp (peeled, deveined, tails removed)
- 8 ounces crab meat (shredded)
- 1 cup chicken stock
- 1 cup clam juice
- 1/2 cup seafood stock
- 1/2 cup butter
- 1/2 Tablespoon garlic salt
- 1/2 Tablespoon Old Bay seasoning
- 1/2 cup all purpose flour
- 2 cups half and half
- 3 cups Colby Jack cheese (shredded)
- 3 cups mozzarella cheese (shredded)
Instructions
- Preheat your oven to 350°F (175°C). Cook the lasagna noodles according to package directions until al dente. Drain, lay them flat on a sheet of parchment paper, and set aside.
- In a large skillet over medium-high heat, melt the butter. Add the green onions and minced garlic, sautéing for 1-2 minutes until fragrant.
- Add the scallops and shrimp to the skillet. Cook for 3-4 minutes, stirring occasionally, until the shrimp are pink and opaque and the scallops are just cooked through. Remove the seafood to a bowl and set aside.
- In the same skillet, pour in the chicken stock, clam juice, and seafood stock. Bring to a simmer, scraping up any browned bits from the bottom of the pan.
- Whisk in the garlic salt and Old Bay seasoning. Reduce heat to medium-low. Gradually sprinkle in the flour while whisking constantly to prevent lumps. Cook for 1-2 minutes.
- Slowly pour in the half and half while whisking continuously. Cook until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Remove from heat.
- Fold the cooked shrimp, scallops, and shredded crab meat into the creamy sauce.
- In a separate bowl, combine the shredded Colby Jack and mozzarella cheeses.
- To assemble, spread a thin layer of the seafood sauce on the bottom of a 9×13 inch baking dish. Arrange 3 lasagna noodles over the sauce.
- Spoon about 1/3 of the seafood sauce over the noodles, then sprinkle with about 1/4 of the cheese mixture.
- Repeat the layers two more times: noodles, sauce, cheese. For the final top layer, add the last 3 noodles, the remaining sauce, and finish with the remaining cheese.
- Cover the dish loosely with foil and bake for 30 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is golden and bubbly. Let the lasagna rest for 10-15 minutes before slicing and serving.
Variations
- Individual Portions: Assemble the lasagna in small, oven-safe ramekins for elegant single servings, adjusting the bake time slightly.
- No-Boil Noodle Hack: Use oven-ready lasagna noodles; you may need to add a bit more sauce or a splash of stock to the dish before baking.
- Spice it Up: Add a pinch of red pepper flakes to the sauce or use a spicy Old Bay seasoning for a kick of heat.
- Fresh Herb Finish: Garnish the baked lasagna with chopped fresh parsley or chives just before serving for a pop of color and freshness.
Tips for Success
- Dry Crab Meat: Gently squeeze excess liquid from the crab meat before adding it to prevent the sauce from becoming watery.
- Don’t Overcook the Seafood: The shrimp and scallops will continue to cook in the oven. Remove them from the skillet as soon as they are just done to keep them tender.
- Layer Carefully: Avoid overfilling layers with sauce, which can make the lasagna too soupy and difficult to slice cleanly.
- Rest is Crucial: Allowing the lasagna to rest after baking lets the layers set, making it much easier to cut into neat portions.
Storage & Reheating
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. For best results, reheat individual portions in the microwave at reduced power or, to maintain texture, cover with foil and reheat in a 325°F oven until warmed through.
FAQ
Can I use pre-cooked seafood?
It’s not recommended. Using raw shrimp and scallops ensures they cook in the sauce, absorbing maximum flavor and staying tender. Pre-cooked seafood will become tough and rubbery.
Can I make this ahead of time?
Yes, assemble the lasagna completely, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time.
Can I freeze seafood lasagna?
You can freeze it after baking. Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge and reheat, covered, in a 325°F oven.
Can I use a different cheese blend?
Absolutely. A sharp white cheddar can be substituted for the Colby Jack, or you can use all mozzarella for a milder flavor.
Is there a substitute for clam juice?
You can use an additional 1 cup of seafood stock, though the clam juice adds a distinctive briny flavor that is part of the dish’s character.
My sauce seems too thick/thin. What can I do?
If too thick after adding the half and half, whisk in a splash more stock. If too thin, let it simmer a few minutes longer to reduce and thicken before assembling.
