Before You Begin

Do not substitute canned or imitation crab here. Do not use flounder fillets thinner than ¼ inch, as they will overcook quickly. Sole may be substituted for the flounder in this recipe.

Instructions

  1. Melt 3 tablespoons butter in 12-inch nonstick skillet over medium heat. Add onion, bell pepper, Old Bay, ½ teaspoon salt, and cayenne. Cook until vegetables are softened, about 5 minutes. Stir in garlic and cook until fragrant, about 30 seconds. Stir in cream. Bring mixture to boil and cook until very thick, about 3 minutes.

  3. Adjust oven rack to middle position and heat oven to 400 degrees. Pat flounder dry with paper towels and sprinkle with remaining ¾ teaspoon salt and pepper. Place flounder, skinned side up, on cutting board and mound ¼ cup filling in middle of each fillet. Fold tapered end of fillet tightly over filling and then fold thicker end of fillet over top to make tidy bundle.
  4. Spray 13 by 9-inch baking dish with vegetable oil spray and lay bundles seam side down in baking dish. Toss panko with 3 tablespoons melted butter and remaining 2 tablespoons parsley; sprinkle over bundles. Roast until panko is golden brown and flounder flakes apart when gently prodded with paring knife, 15 to 20 minutes. Serve with lemon wedges.

Why This Recipe Works

We kept the filling simple by sautéing some aromatics, cayenne, and Old Bay on the stovetop, adding cream for richness, and folding in the crabmeat before chilling the mixture to meld its flavors. We placed a small mound of the crab stuffing on each flounder fillet, rolled them up, sprinkled them with buttered panko, and roasted the stuffed fillets in a hot oven. In 15 minutes or so we had something special: tender, flaky fillets filled with a creamy stuffing and a touch of crunch from the buttery panko.
