Ingredient Notes, Expert Tips & Clever Substitutions:

• Flounder Fillets: Flounder refers to a family of flatfish species, not a single type, characterized by its delicate, mild taste and beautifully flaky texture. It is typically sold as thin fillets, which are ideal for rolling around a savory filling like our crab mixture. The most commonly available variety in many regions is Summer Flounder, also known as “Fluke,” highly prized for its quality. When selecting flounder, consider its thinness, which is crucial for successful rolling. Due to its unique structure, finding a perfect substitute for rolling can be challenging, though sole is a viable alternative if available. For other fish types, please consult the “Quick Answers” section below for alternative preparation methods. Always prioritize sustainably sourced seafood where possible.
• Shallot: A distinguished member of the onion family, shallots are a staple in classic French cuisine. They grow in clusters, similar to garlic but with a more refined, delicate flavor profile—often described as a subtle fusion of onion and garlic. This nuanced taste makes shallots an exquisite choice for enhancing the mildness of flounder without overpowering the delicate crab. Finely chopping ensures even distribution and quick softening.
• Old Bay Seasoning: This iconic seasoning blend, first introduced in 1939, is practically synonymous with seafood in the Mid-Atlantic. You likely already have this versatile spice in your pantry (and if not, it’s a perfect time to replenish!). Old Bay is a masterful blend of salt, paprika, celery seed, black pepper, mustard, red pepper, and ground bay leaves, offering a distinctive, savory warmth. If Old Bay is unavailable, a good quality Cajun seasoning can serve as an excellent substitute, providing a similar complex spice profile.
• Lump Crab Meat: For the ultimate stuffing experience, prioritize lump crab meat. This consists of large, intact pieces of white crab meat from the body of the crab, offering a superior texture and intensely sweet flavor that elevates the dish. While all crab sold globally is wild-caught, it is highly recommended to stick with crab sourced from U.S. waters. Avoid imported crab when possible, as sourcing practices in some parts of the world can involve illegal fishing, environmentally damaging methods, or unfair labor practices. Before incorporating, always inspect the crab meat carefully for any stray shell fragments and rinse gently if necessary to ensure purity.
• Dry White Wine: The choice of wine in your cooking is paramount. Always use a dry white wine that you would genuinely enjoy drinking. Varieties like Sauvignon Blanc, Pinot Grigio, or a dry Chardonnay are excellent choices, contributing a bright acidity and depth to the sauce.
  • NON-ALCOHOLIC SUBSTITUTE: If you prefer to avoid alcohol, substitute the dry white wine with an equal amount of chicken or fish stock, enhanced with a tablespoon of fresh lemon juice. This will provide a similar acidic lift and savory base to the sauce.

Step-By-Step Instructions for Culinary Perfection:

Follow these detailed steps to create your magnificent Crab-Stuffed Flounder:

• Begin by gathering and precisely prepping all your ingredients. This mise en place ensures a smooth and enjoyable cooking process.
• Preheat your oven to a steady 400 degrees Fahrenheit (200 degrees Celsius).
• Lightly spray a baking dish that’s appropriately sized to hold your rolled fish fillets, such as an 11 x 7-inch gratin dish, with cooking spray to prevent sticking.
• In a small skillet or sauté pan, melt 2 tablespoons of unsalted butter over medium heat. Once the butter is shimmering, add the finely chopped shallot and red bell pepper.
• Sauté these aromatic vegetables for approximately 4 to 5 minutes, or until they become very soft and translucent. Be vigilant not to let them brown, as this can alter their delicate flavor.
• Carefully transfer the cooked vegetables, along with any residual butter from the pan, into a medium-sized mixing bowl.

• To the bowl with the softened vegetables, add 1 1/2 tablespoons of fresh parsley, Worcestershire sauce, mayonnaise, dry mustard, 1/2 teaspoon of Old Bay seasoning, a pinch of cayenne pepper (adjust to your taste and heat tolerance), finely crushed Saltine crackers, and the star of the stuffing – the lump crab meat.
• Stir all the ingredients thoroughly until they are well combined. Taste and season with salt and freshly ground black pepper as needed, ensuring the filling is perfectly balanced.

• Gently flip your flounder fillets so that what was originally the skin side is now facing upwards. This orientation makes rolling easier.
• Carefully place an equal portion of the crab filling into the center of each flounder fillet.
• Roll up each fillet, enclosing the savory filling. If necessary, secure the rolled fish with a toothpick to prevent it from unraveling during baking.
• Arrange the stuffed flounder rolls seam-side down in your prepared baking dish.

• In a separate bowl, whisk together the dry white wine, heavy cream, all-purpose flour, and the remaining 1/8 teaspoon of Old Bay seasoning until smooth and fully combined. This mixture will form your luscious sauce.

• Gently pour the prepared sauce around the base of the fish fillets in the baking dish.
• Dot the tops of the rolled fillets with the remaining 1 tablespoon of unsalted butter. This step is crucial for keeping the fish moist and tender during baking.

• Bake the flounder uncovered for 20 to 25 minutes, or until the sauce is visibly bubbling around the fish, and an instant-read thermometer inserted into the center of the crab filling registers 155 degrees Fahrenheit (68 degrees Celsius).

• Once baked, carefully transfer the delicate fillets to a serving platter or individual plates.
• Stir the sauce remaining in the baking dish to fully incorporate the melted butter, creating a rich, glossy consistency. Spoon this decadent sauce generously over and around the fish.
• Garnish your masterpiece with the remaining fresh chopped parsley and serve immediately with bright lemon wedges for a zesty finish.

Crab-Stuffed Flounder: Expert Tips for a Perfect Finish

• Due to the naturally thin nature of flounder fillets, they occasionally tend to split down the middle where the spine was once removed after baking. Rest assured, this is perfectly normal and doesn’t detract from the dish’s flavor or presentation. In fact, the slightly exposed, golden-brown filling often adds to the rustic charm of the dish, creating an inviting visual appeal.
• The step of dotting the fish with butter before baking is essential. This butter acts as a protective layer, ensuring the delicate fish remains incredibly moist and prevents it from drying out in the oven. It is important to note that the butter will naturally melt and become fully incorporated into the creamy sauce after stirring. So, after carefully removing the stuffed flounder fillets to your platter or individual dinner dishes, simply give the sauce a quick stir to emulsify, and then generously spoon it over and around the perfectly cooked fish.

• 2 tablespoons chopped fresh parsley, divided
• 1/2 teaspoon Worcestershire sauce
• 1 tablespoon mayonnaise

Instructions

1. Preheat your oven to 400 degrees Fahrenheit (200°C). Lightly spray a baking dish (approx. 11 x 7-inch) large enough to hold the rolled fish fillets with cooking spray.
2. Heat 2 tablespoons of butter in a small skillet or sauté pan over medium heat. Once melted, add the finely chopped shallot and red bell pepper. Cook for 4-5 minutes, or until the vegetables are very soft and translucent, taking care not to brown them. Transfer the softened vegetables, along with all the butter from the pan, to a mixing bowl.
3. To the bowl, add 1 1/2 tablespoons of fresh parsley, Worcestershire sauce, mayonnaise, dry mustard, 1/2 teaspoon of Old Bay seasoning, cayenne pepper (to taste), finely crushed Saltine crackers, and the lump crabmeat. Stir all ingredients together thoroughly until well combined. Season with salt and freshly ground black pepper to taste.
4. Lay the flounder fillets flat, with the former skin side facing up. Place equal amounts of the crab filling in the center of each fillet. Carefully roll up each fillet to enclose the filling. Secure with a toothpick if necessary to prevent unrolling. Place the rolled fillets seam-side down in the prepared baking dish.
5. In a separate bowl, whisk together the dry white wine, heavy cream, all-purpose flour, and the remaining 1/8 teaspoon of Old Bay seasoning until smooth.
6. Pour the prepared sauce evenly around the fish fillets in the baking dish. Dot the tops of the rolled fillets with the remaining 1 tablespoon of butter.
7. Bake uncovered for 20-25 minutes, or until the sauce is bubbling and an instant-read thermometer inserted into the center of the crab filling registers 155 degrees Fahrenheit (68°C).
8. Carefully transfer the baked fillets to a serving platter or individual plates. Stir the sauce in the baking dish to incorporate the melted butter, and then generously spoon it over and around the fish.
9. Garnish with the remaining chopped fresh parsley and serve immediately with fresh lemon wedges.

Notes

• Due to the thin nature of flounder, it may slightly split after baking. This is natural and the exposed filling adds to its appeal.

SUBSTITUTIONS:

• See the FAQs section above for suggestions on alternate fish.
• Cajun seasoning can be used as a good substitute for Old Bay.
• For a non-alcoholic option, replace dry white wine with chicken or fish stock plus 1 tablespoon of lemon juice.

• Combine sauce ingredients, cover, and refrigerate separately.
• When ready to bake, pour the sauce around the fish and proceed with baking as directed.
