For Laura's seafood Thermidor recipe, use crab or lobster or mix it up with some fish. I serve this in individual au gratin dishes. You can freeze the sauce before adding the topping.

Ingredients

Oops! Something went wrong. Our team is working on it.

Original recipe (1X) yields 4 servings

½ cup unsalted butter
8 ounces fresh mushrooms, chopped
1 bunch green onions, chopped
4 ounces peeled and deveined medium shrimp (30-40 per pound)
4 ounces walleye fillets, cut into pieces
4 ounces cooked lobster meat, broken into chunks
4 ounces cooked crabmeat
½ cup dry white wine (such as Chenin Blanc)
2 tablespoons dry sherry
1 ½ cups dry bread crumbs, divided
1 (10.5 ounce) can condensed cream of shrimp soup (such as Campbell's)
1 cup half-and-half
4 ounces shredded Cheddar cheese
½ cup freshly grated Parmesan cheese
¼ cup unsalted butter, cold, cut into 1/2-inch pieces

Directions

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
Melt 1/2 cup butter in a large skillet over medium heat. Add mushrooms and green onions; cook and stir until mushrooms softened, about 5 minutes. Stir in shrimp and walleye; cook and stir until shrimp begin to turn opaque, about 2 minutes. Add lobster and crab; cook until heated through, about 3 minutes.
Stir in white wine and sherry; bring to a simmer and cook until shrimp and walleye are no longer translucent in centers, about 2 minutes. Stir in 1 cup bread crumbs, soup, half-and-half, and Cheddar cheese until cheese melted and mixture is bubbly. Transfer to a casserole dish; sprinkle evenly with remaining 1/2 cup bread crumbs and Parmesan cheese. Dot with cold butter.
Cook under the preheated broiler until butter has melted and bread crumbs are golden brown.
