Ingredient Notes & Details

Flounder fillets

Look for fresh, thin flounder fillets that are flexible enough to roll. If flounder isn’t available, sole or tilapia can work as substitutes in this baked seafood recipe.

Crab meat

Lump crab meat gives the stuffing the best texture and flavor. If needed, claw meat can be used, but try to avoid imitation crab for the best results.

Breadcrumbs

Plain or panko breadcrumbs help bind the stuffing while keeping it light. Panko creates a slightly airier texture.

Mayonnaise

Adds richness and moisture to the crab filling. Greek yogurt can be used as a lighter alternative.

Egg

Helps hold the stuffing together while baking.

Dijon mustard

Adds a subtle tang that balances the richness of the crab.

Garlic

Fresh minced garlic gives the filling a deep savory flavor.

Fresh parsley

Brightens the stuffing and adds a fresh herbal note.

Lemon juice

A little acidity enhances the flavor of the fish and crab.

Butter

Drizzled on top before baking to keep the fish moist and flavorful.

Paprika

Adds color and a mild smoky warmth to the dish.

Step-by-Step Instructions

Step 1: Preheat the oven

Preheat your oven to 375°F (190°C). Lightly grease a baking dish large enough to hold the stuffed fillets in a single layer.

This temperature allows the fish to cook gently while the stuffing becomes perfectly golden.

Step 2: Prepare the crab stuffing

In a medium bowl combine:

1 cup lump crab meat
½ cup breadcrumbs
2 tablespoons mayonnaise
1 beaten egg
1 teaspoon Dijon mustard
1 minced garlic clove
2 tablespoons chopped parsley
1 tablespoon lemon juice
Salt and pepper to taste

Mix gently so the crab stays in nice chunks.

The mixture should be moist but still hold together when pressed lightly.

Step 3: Prepare the flounder fillets

Lay the flounder fillets flat on a clean surface.

If they are very thin, you can overlap two slightly to create a stronger base for the stuffing.

Pat them dry with paper towels so they bake evenly.

Step 4: Add the stuffing

Place a generous scoop of the crab mixture in the center of each fillet.

Carefully fold or roll the fish around the stuffing to form a neat bundle.

Place each stuffed fillet seam-side down in the prepared baking dish.

Step 5: Add butter and seasoning

Melt 2 tablespoons of butter and drizzle it over the fish.

Sprinkle lightly with paprika and an extra pinch of salt and pepper.

This helps the fish develop a beautiful golden color as it bakes.

Step 6: Bake the stuffed flounder

Bake in the preheated oven for 18–22 minutes.

The fish should be opaque and flaky, and the stuffing should be hot and lightly golden.

Avoid overcooking—flounder cooks quickly.

Step 7: Finish with lemon

Once out of the oven, squeeze fresh lemon juice over the top and garnish with extra parsley.

Serve immediately while warm and tender.

FAQ for Common Questions

What is the best crab meat for Crab Stuffed Flounder?

Lump crab meat is the best option because it has large, tender pieces and a naturally sweet flavor that stands out in the stuffing.

Can I make Crab Stuffed Flounder ahead of time?

Yes. You can assemble the stuffed fillets several hours in advance and store them covered in the refrigerator until ready to bake.

How do I know when flounder is fully cooked?

The fish should turn opaque and flake easily with a fork. Overcooked flounder becomes dry, so keep an eye on it near the end of the baking time.

Is this recipe low carb or keto-friendly?

It can be. Simply replace the breadcrumbs with crushed pork rinds or almond flour for a low carb Crab Stuffed Flounder variation.

Can I use frozen flounder fillets?

Yes, but thaw them completely and pat them very dry before assembling the recipe.

Absolutely. Sole, tilapia, or even thin cod fillets can work well in this baked stuffed fish recipe.

Storage Tips

Refrigeration

Store leftover Crab Stuffed Flounder in an airtight container in the refrigerator for up to 2 days.

Freezing

Thaw overnight in the refrigerator before baking.

Reheating

Reheat in a 325°F oven for 10–12 minutes until warmed through. Avoid microwaving if possible, as it can make the fish rubbery.
