How to Make Crispy Fried Flounder with Homemade Tartar Sauce Recipe
Step 1: Prepare the Seasoned Breadcrumbs
Begin by combining the plain bread crumbs with the minced parsley, dried oregano, garlic powder, sea salt, and black pepper in a medium bowl. This seasoned breadcrumb mixture is the magic that will coat each flounder fillet, giving it that irresistible crunch and extra layers of flavor that make the dish unforgettable. Thoroughly mix everything together and set it aside while you prep the fish.
Step 2: Season and Prep the Fish
Pat your flounder fillets dry using paper towels—this step is crucial to ensure the coating adheres well. Then, generously season both sides of each fillet with salt and pepper. Well-seasoned fillets are the foundation of this dish’s deliciousness, so don’t be shy with the seasoning.
Step 3: Dredge the Fillets
Set up your dredging station with three shallow dishes: one with flour, the second with beaten eggs, and the third with the seasoned breadcrumbs you just prepared. Take each fillet and first coat it lightly in flour, shaking off any excess. Next, dip the fillet in the beaten eggs before pressing it firmly into the breadcrumb mixture, ensuring it’s completely coated. Place the breaded fillets on a parchment-lined baking sheet and keep them ready for frying.
Step 4: Heat the Oil
Pour neutral oil into a heavy-bottomed pan to about half an inch deep. Heat the oil to between 360 and 370°F (182-188°C), the perfect temperature range for frying to achieve that golden crunch without absorbing excess oil. Monitoring the heat carefully is key to getting a crispy exterior that’s not greasy.
Step 5: Fry the Flounder
Carefully slide the breaded fillets into the hot oil in batches, being careful not to overcrowd the pan. Fry each piece for 3 to 4 minutes per side, or until the coating turns a beautiful golden brown and the fish flakes easily with a fork. Transfer the cooked fillets to a wire rack or plate lined with paper towels to drain any excess oil for that perfect balance of crisp and lightness.
Step 6: Make the Tartar Sauce
While your flounder is frying, whip up the homemade tartar sauce. In a bowl, combine mayonnaise, fresh lemon juice, caper paste, relish, Dijon mustard, and Tabasco. Stir well and season with salt and pepper to taste. This sauce bursts with tangy, creamy, and slightly spicy notes that bring out the best in the fried flounder.
Step 7: Serve and Enjoy
Arrange your crispy fried flounder on a platter, spoon the luscious tartar sauce into a serving bowl, and add fresh lemon wedges on the side. This is a dish best enjoyed immediately, when the coating is still delightfully crispy and the tartar sauce is fresh and zesty.
How to Serve Crispy Fried Flounder with Homemade Tartar Sauce Recipe

Garnishes
A sprinkle of fresh chopped parsley or a few lemon wedges brighten the plate while adding subtle freshness that complements the flounder’s crispy crust and creamy sauce. A dash of extra black pepper or a light drizzle of olive oil can also enhance the presentation and flavor.
Side Dishes
Crispy Fried Flounder with Homemade Tartar Sauce Recipe pairs wonderfully with classic sides like fluffy mashed potatoes, crisp coleslaw, or a simple green salad dressed with vinaigrette. For a coastal feel, try serving it alongside roasted vegetables or a tangy cucumber salad for added crunch and color.
Creative Ways to Present
Consider assembling crispy fried flounder sliders with soft brioche buns and a dollop of the tartar sauce for a fun twist. Alternatively, use the fish as a protein topper for grain bowls with wild rice, avocado slices, and fresh herbs, making for a stunning and wholesome presentation that’s perfect for sharing.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers from this Crispy Fried Flounder with Homemade Tartar Sauce Recipe, store them in an airtight container in the refrigerator for up to two days. Be sure the fish has cooled completely before sealing it to maintain texture as much as possible.
Freezing
While fried flounder is best enjoyed fresh, you can freeze cooked fillets by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag. They will keep well for up to one month. For optimal texture, reheat gently to avoid drying out the fish.
Reheating
To reheat, place the fillets on a baking sheet in a preheated oven at 350°F (175°C) for 10 to 15 minutes or until warmed through. This method helps restore some crispiness without making the fish soggy, unlike microwaving which can make the coating chewy.
FAQs
Can I use other types of fish for this recipe?
Absolutely! While flounder is ideal because of its delicate texture, you can substitute with other mild white fish like sole, tilapia, or cod. Just make sure the fillets are not too thick to ensure even frying.
How do I know the oil is at the right temperature?
The best way is to use a cooking thermometer aiming for 360-370°F. If you don’t have one, drop a small piece of bread or batter into the oil — if it sizzles and browns quickly, the oil is ready.
Is the homemade tartar sauce necessary?
While optional, the homemade tartar sauce adds a fresh and flavorful dimension that transforms the fried flounder experience. It’s easy to make and much tastier than store-bought alternatives.
Can I make the tartar sauce ahead of time?
Yes! The tartar sauce can be made up to 2 days in advance and stored in the fridge in a sealed container. Just give it a good stir before serving.
What’s the best oil to use for frying flounder?
Neutral oils with a high smoke point like canola, vegetable, or peanut oil work best. They fry the fish crisply without adding unwanted flavors.
