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 for al dente. Drain, rinse with cold water, and lay flat on a sheet of parchment paper to prevent sticking.
- While the noodles cook, prepare the seafood. Pat the scallops and shrimp dry with a paper towel. If using sea scallops, chop them into bite-sized pieces.
- In a large skillet or Dutch oven, melt the butter over medium heat. Add the green onions and garlic, sautéing for 1-2 minutes until fragrant.
- Add the scallops and shrimp to the skillet. Cook, stirring occasionally, for 3-4 minutes, or until the shrimp are just pink and opaque. The seafood will finish cooking in the oven. Gently stir in the crab meat and remove the skillet from the heat.
- To the seafood mixture in the skillet, sprinkle the flour, garlic salt, and Old Bay seasoning over everything. Stir well to coat and cook for 1 minute.
- Gradually pour in the chicken stock, clam juice, and seafood stock, stirring constantly to prevent lumps. Bring to a gentle simmer until the mixture thickens slightly.
- Reduce heat to low. Slowly stir in the half and half until fully incorporated and the sauce is smooth and creamy. Let it simmer for another 2-3 minutes, then remove from heat.
- In a separate bowl, combine the shredded Colby Jack and mozzarella cheeses.
- To assemble, spread about 1 cup of the seafood sauce in the bottom of a 9×13 inch baking dish. Arrange 4 lasagna noodles over the sauce.
- Top the noodles with one-third of the remaining seafood sauce, followed by one-third of the cheese mixture. Repeat the layers twice more: noodles, sauce, cheese. The final layer should be cheese.
- Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
- Let the lasagna rest for 10-15 minutes before slicing and serving.
Variations
- Individual Portions: Layer the ingredients in individual oven-safe ramekins for elegant, personal servings.
- White Sauce Base: For a bolder white sauce flavor, reduce the chicken stock and use all clam juice and seafood stock.
- No-Boil Noodle Method: Use no-boil lasagna noodles. Simply ensure your sauce is slightly thinner (add a splash more stock) to provide enough liquid for the noodles to cook through.
- Broil Finish: For an extra-crispy, browned cheese topping, switch the oven to broil for the final 1-2 minutes of cooking (watch closely!).
Tips for Success
- Ensure your shrimp and scallops are patted very dry before sautéing to prevent excess water from thinning your sauce.
- Shred your own cheese from a block; pre-shredded cheese contains anti-caking agents that can make your sauce grainy and less smooth.
- Don’t overcook the shrimp and scallops in the skillet—they only need to be about 75% done, as they will finish cooking in the hot oven.
- Allowing the lasagna to rest after baking is crucial. It lets the layers set, making it much easier to cut clean slices.
Storage & Reheating
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover a portion with foil and warm in a 350°F oven for 15-20 minutes, or until heated through. For a single serving, microwave on medium power in 60-second intervals, stirring gently in between.
FAQ
Can I use frozen seafood?
Yes, thaw completely in the refrigerator and pat it very dry before using to avoid a watery sauce.
Can I make this lasagna ahead of time?
Absolutely. Assemble the lasagna, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time.
What can I substitute for clam juice?
If you cannot find clam juice, you can use an additional 1 cup of seafood or chicken stock, though you will lose some of the distinct seafood flavor.
Is there a substitute for Old Bay seasoning?
You can use a simple blend of paprika, celery salt, and a pinch of cayenne pepper, or use any other seafood seasoning blend you prefer.
My sauce seems too thick. What should I do?
If your sauce thickens too much before assembly, you can thin it with a small splash of additional stock, clam juice, or half and half.
Can I freeze seafood lasagna?
It’s possible but not ideal, as the dairy-based sauce can become grainy and the seafood may become rubbery upon thawing and reheating. For best quality, enjoy it fresh or refrigerated.
