This should not be saved just for Lent. Personally I would rather have this than regular lasagna. So would my nephew. Salad and garlic bread and you are done.
12 lasagna noodles (sometimes I only use 9)
3 tablespoons unsalted butter
1 small onion, finely chopped
2 cloves garlic, minced
3 tablespoons all-purpose flour
2 1/2 cups half and half
1 cup grated Romano cheese
1/2 teaspoon salt
1/4 teaspoon pepper
3/4 pound sea scallops, cut in half or quartered if very large
3/4 pound medium shrimp, peeled and deveined
4-6 ounces crab meat (optional)
1/2 cup grated Parmesan
Preheat oven to 375 degrees F. Spray a 13 x 10-inch aluminum foil pa with vegetable cooking spray. Trust me you don't want to clean the pan.
In a large pot of boiling salted water, cook the lasagna noodles until they are just done, about 8 minutes. Drain and set aside.
Melt the butter in a large, heavy skillet and cook the onion over low heat until very soft, about 5 minutes. Add the garlic and cook about 1 minute more. Over medium-low heat, stir in the flour with a whisk, then gradually add the half-and-half, allowing the sauce to thicken slightly before adding more. When the sauce has thickened to about the consistency of whipping cream, add the cheese and stir well. Add the salt and pepper and stir again. Add the scallops and cook for about 3 to 4 minutes, then add the shrimp and cook for 1 to 2 minutes or just until the shrimp turn pink. Turn off the heat.
Spoon about 2 tablespoons of the sauce from the skillet into the prepared pan. Cover the bottom with 4 noodles, placing them side by side. Spoon 1/3 of the sauce over the noodles, distributing half of the seafood evenly. Layer 4 more noodles, 1/3 of the sauce, and remaining seafood. Cover with the last 4 noodles and the remaining sauce. (For the top layer, do not spoon any seafood on top of the noodles; just the sauce.) Tuck in any edges of the noodles so they're coated with sauce. Top with the Parmesan.
Bake for 20-25 minutes, uncovered, until bubbly. Allow to sit for 10-15 minutes before slicing.
