- Neutral oil (enough to fill pan 1/2-inch high): Ideal for frying without interfering with the flavor.

How to Make Crispy Fried Flounder with Tangy Tartar Sauce Recipe
Step 1: Prepare the Seasoned Breadcrumbs
Start by mixing together the plain bread crumbs, minced parsley, dried oregano, garlic powder, sea salt, and black pepper in a medium bowl. This herbaceous and flavorful coating will be key in delivering that unforgettable crunch and taste every time you bite into the fish.
Step 2: Season and Prep the Flounder
Pat your flounder fillets dry using paper towels — this step is crucial because excess moisture can prevent the coating from sticking properly. Then, season both sides generously with salt and pepper to give the fillets a baseline of flavor before they meet the batter and breadcrumbs.
Step 3: Dredge the Fillets
Set up a classic dredging station with three shallow dishes: one with flour, one with beaten eggs, and one with your seasoned breadcrumb mixture. Carefully coat each fillet first in flour, shaking off any excess, then dip into the beaten eggs, and finally press into the breadcrumbs until fully coated. The triple-step dredging ensures a sturdy, crispy crust that stays put during frying.
Step 4: Heat the Oil
Pour enough neutral-flavored oil into a heavy skillet to reach about half an inch depth. Heat the oil to between 360 and 370 degrees Fahrenheit (182-188°C) — using a thermometer here will help achieve that perfect frying temperature where the breading crisps up instantly without soaking up too much oil.
Step 5: Fry the Flounder
Carefully lower the coated fillets into the hot oil without overcrowding the pan to maintain temperature consistency. Fry each side for 3 to 4 minutes, or until golden brown and cooked all the way through. Transfer the cooked fillets to a wire rack or plate lined with paper towels to drain excess oil, keeping your crispy masterpiece light and not greasy.
Step 6: Make the Tangy Tartar Sauce
While the fish fries, whip up the tangy tartar sauce by mixing mayonnaise, fresh lemon juice, mashed capers, relish, Dijon mustard, and Tabasco in a bowl. Taste and season with salt and pepper as needed. This sauce is the bright, creamy complement that brings everything together — the perfect partner for your fried flounder.
Step 7: Serve and Enjoy
Arrange your crispy fillets on a platter, dollop or serve the tartar sauce alongside, and garnish with fresh lemon wedges to squeeze over just before eating. This final touch adds a zesty freshness that elevates the whole dish to something truly memorable.
How to Serve Crispy Fried Flounder with Tangy Tartar Sauce Recipe

Garnishes
A simple wedge of fresh lemon is all you need to brighten up each bite, but feel free to also sprinkle a little extra chopped parsley over the fish for a pop of green and fresh aroma. The contrast of the tangy, herby tartar sauce with lemon juice makes every mouthful a celebration of flavors.
Side Dishes
This Crispy Fried Flounder with Tangy Tartar Sauce Recipe pairs wonderfully with crispy French fries for a classic combination, or you can keep it light and fresh with a crisp green salad drizzled in vinaigrette. Roasted vegetables or a creamy coleslaw also make excellent companions, balancing the crunchy fish with fresh textures and flavors.
Creative Ways to Present
For a fun twist, serve your fried flounder in soft sandwich buns with lettuce and tartar sauce for a delicious fish sandwich experience. You can also serve bites skewered with lemon slices and parsley sprigs for an elegant appetizer-style presentation at parties or gatherings. These little presentations can transform a humble fried fish dish to something visually exciting.
Make Ahead and Storage
Storing Leftovers
If you happen to have some leftovers (though they’re likely to disappear fast!), store the fried flounder in an airtight container in the refrigerator. It will keep well for up to two days, but for best texture, try to enjoy them the same day whenever possible.
Freezing
While fried fish is best fresh, you can freeze the flounder fillets before frying. Prepare and coat each fillet as directed, place them on a parchment-lined tray, freeze until solid, then transfer to a freezer bag. When ready to cook, fry directly from frozen with a bit more time to reach perfect golden crispiness.
Reheating
To reheat, avoid the microwave as it often makes the crust soggy. Instead, use a hot oven or an air fryer at 350 degrees Fahrenheit for 10 minutes or until heated through and crisp restored. This way, your Crispy Fried Flounder with Tangy Tartar Sauce Recipe tastes almost like fresh off the stove.
FAQs
Can I use another type of fish for this recipe?
Yes! While flounder is wonderfully tender and mild, you can substitute with other flaky white fish like sole, cod, or haddock. Just adjust frying time slightly depending on thickness.
Is it necessary to use neutral oil for frying?
Neutral oils like vegetable, canola, or peanut oil are best because they have high smoke points and won’t overpower the delicate flavor of the flounder. Olive oil can be used but watch the temperature closely.
Can I make the tartar sauce ahead of time?
Absolutely! The tartar sauce actually benefits from resting a few hours or even overnight in the refrigerator as the flavors meld beautifully. Just give it a quick stir before serving.
How do I know when the oil is hot enough for frying?
Using a cooking thermometer is most accurate. The oil should be between 360-370°F. If you don’t have one, test by dropping a small piece of bread crumb in the oil; it should sizzle and turn golden within a few seconds.
Can this recipe be made gluten-free?
Definitely! Simply swap the regular bread crumbs and flour for gluten-free versions, and make sure your other ingredients like relish are gluten-free. The results will still be deliciously crispy and flavorful.

Instructions
- Prepare the Seasoned Breadcrumbs: In a medium mixing bowl, combine the plain bread crumbs, minced parsley, dried oregano, garlic powder, sea salt, and black pepper. Mix thoroughly and set aside for coating the fish.
- Season and Prep the Fish: Pat the flounder fillets dry with paper towels. Season both sides with salt and pepper to taste to ensure maximum flavor once fried.

- Serve: Arrange fried flounder on a platter and serve immediately with homemade tartar sauce and fresh lemon wedges.

- Do not overcrowd the pan to maintain oil temperature and crispiness.
- Pat fish dry before seasoning for better breadcrumb adherence.
- The tartar sauce can be prepared ahead and refrigerated for up to 2 days.
- Use a heavy-bottomed pan for even heating during frying.
- Drain the fried fillets on a wire rack instead of paper towels to keep crust crispy.
