Ingredients
Fresh Flounder and Other Essentials
To make the ultimate fried flounder sandwich, you’ll need fresh flounder fillets, all-purpose flour, cornmeal, eggs, and a few spices to enhance the flavor. Don’t forget the soft sandwich rolls and fresh lettuce for serving.
Homemade Tartar Sauce Ingredients
The homemade tartar sauce is a standout element in this recipe. You’ll need mayonnaise, pickles, capers, lemon juice, and a touch of dill to create a sauce that perfectly complements the crispy flounder.

Step-by-Step Instructions
Preparing the Flounder
Start by patting the flounder fillets dry and seasoning them with salt and pepper. Prepare a dredging station with flour, beaten eggs, and a cornmeal mixture to coat the fillets evenly.
Frying to Perfection
Heat oil in a deep skillet to 350°F. Fry the flounder fillets until golden brown and crispy, about 3-4 minutes per side. Drain on paper towels to remove excess oil.
Assembling the Sandwich
Toast the sandwich rolls and layer with lettuce, the fried flounder fillet, and a generous dollop of homemade tartar sauce. Serve immediately for the best taste.
Pro Tips
For the best results, follow these expert tips:
- Ensure your oil is hot enough before frying to achieve the crispiest coating.
- Use fresh flounder for the best flavor and texture.
- Customize the tartar sauce by adding a pinch of cayenne pepper for a spicy kick.
- Let the fried fish rest on a wire rack to maintain crispiness rather than becoming soggy.
The most crucial tip is to enjoy your sandwich as soon as it’s assembled, as the textures and flavors are at their peak when fresh.
