A pan sauce built from butter, onion, garlic, flour, half-and-half, chicken broth, and a third cup of dry sherry thickens into a cream base that layers with nine lasagna noodles, a ricotta-Parmesan-egg mixture, chopped imitation crabmeat, cooked shrimp, and three cups of shredded mozzarella. Eight servings bake in about 45 minutes at 350°F after a full assembly. The sherry is optional — chicken broth substitutes without changing the structure of the sauce. Let the lasagna rest for 15 minutes before cutting so the layers hold their shape.
