Southern-style crispy fried flounder—golden, flaky, and irresistibly delicious with a squeeze of lemon and a side of tartar sauce.
Few dinners deliver the same combination of crunch and tenderness as crispy fried flounder. Thin flounder fillets cook quickly, while a seasoned cornmeal-and-flour coating creates a golden crust around the mild, flaky fish.
A short buttermilk soak adds flavor and helps the coating cling to the fillets before frying. Garlic powder, paprika, black pepper, and optional cayenne give the crust plenty of seasoning without overpowering the fish.
Serve this Southern-style fried flounder with lemon wedges, tartar sauce, coleslaw, fries, green beans, or a fresh salad for an easy seafood dinner. For more fish and shrimp inspiration, browse YumAndRun’s 8 Easy Seafood Dinner Recipes for Busy Weeknights.

Quick cooking: Thin flounder fillets fry in just a few minutes per side.

Buttermilk is useful here for two reasons.
First, it adds a subtle tangy flavor. More importantly, the wet surface helps the cornmeal-and-flour coating stick evenly to the fish.
Because flounder fillets are thin and delicate, they don’t need an especially long soak. About 15–30 minutes is enough for this recipe.
After removing the fillets from the buttermilk, let the excess drip away before coating them. Too much liquid can create clumps in the breading rather than an even crust.
If you’re using frozen flounder, thaw it completely before cooking.
The FDA recommends thawing frozen seafood gradually in the refrigerator overnight. For quicker thawing, seafood can be sealed in a plastic bag and submerged in cold water. U.S. Food and Drug Administration
FDA guide to selecting, thawing, and preparing seafood safely
Once thawed, pat the fillets dry with paper towels.
Season lightly with salt and black pepper.
Place the flounder fillets in a shallow dish and pour the buttermilk over them.
Let them rest for approximately 15–30 minutes in the refrigerator.
Avoid leaving raw fish sitting at room temperature while you prepare the remaining ingredients.
In a wide, shallow bowl, combine:
Whisk everything together so the seasoning is distributed throughout the coating.
The combination of flour and cornmeal gives you the best of both textures: flour helps the coating adhere while cornmeal contributes extra crunch.
Lift each fillet from the buttermilk and allow the excess to drip off.
Place the fish into the seasoned cornmeal mixture and coat both sides.
Press the coating gently onto the surface rather than aggressively handling the fish, since flounder fillets can be delicate.
Set the coated fillets aside for approximately 5–10 minutes while you heat the oil. This short rest can help the coating adhere more securely.
Pour about ½ inch of oil into a heavy skillet.
Heat the oil to approximately 350°F (175°C).
A cooking thermometer is the easiest way to maintain a consistent frying temperature.
If the oil isn’t hot enough, the coating can absorb excess oil and become heavy or soggy.
If the oil becomes excessively hot, the outside may brown before the fish is properly cooked.
Carefully lower the coated fillets into the hot oil.
Do not crowd the skillet. Fry in batches if necessary.
Cook for approximately 3–4 minutes per side, depending on the thickness of the fillets.
The crust should become crisp and golden brown.
More importantly, check the internal temperature of the fish rather than relying only on color.
The FDA recommends cooking most seafood to 145°F (63°C). U.S. Food and Drug Administration
Transfer the fried flounder to a wire rack or paper-towel-lined plate to remove excess oil.
A wire rack generally does a better job of preserving the crisp coating because air can circulate underneath the fish.
Serve immediately with lemon wedges and your favorite sauce.
The difference between crisp fried fish and soggy fried fish usually comes down to a few small details.
Excess surface moisture can interfere with the coating.
Adding too many fillets at once can cause the oil temperature to drop quickly.
Cook in batches instead.
Give the coating time to become golden before turning the fish.
Stacking hot fried fish traps steam, which softens the coating.
Arrange finished fillets in a single layer whenever possible.
Fried fish has its best texture immediately after cooking.
Yes.
If you prefer an especially substantial crust, try a second coating.
Dip the fillet into the dry mixture, return it briefly to the buttermilk, then coat it again.
The second coating will create a thicker crust, so you may need slightly more cornmeal mixture than the original recipe calls for.
For a more delicate fried flounder, stick with a single coating.
Cook flounder until the thickest portion reaches 145°F (63°C).
FDA seafood guidance recommends 145°F for most seafood and notes that cooked fish should become opaque and separate easily with a fork. U.S. Food and Drug Administration
A thermometer is still the most reliable way to check.
This is especially useful with fried fish because the crust may look finished before the center has reached the appropriate temperature.
Crispy fried flounder works with both traditional Southern sides and lighter vegetable-based sides.

For a lighter meal, serve it with roasted vegetables, cucumber salad, mixed greens, or steamed broccoli.

Both fresh and properly frozen flounder can work well in this recipe.
When purchasing fresh fish, FDA guidance recommends choosing fillets with firm flesh and no drying or discoloration around the edges. Fish should smell fresh and mild rather than sour, rancid, or strongly fishy. U.S. Food and Drug Administration
For frozen seafood, avoid packages that are open, damaged, or filled with excessive ice crystals, which may indicate thawing and refreezing. U.S. Food and Drug Administration
FDA seafood buying and storage guidance
Absolutely.
Frozen flounder is convenient and can produce excellent fried fish when thawed properly.
Thaw it in the refrigerator, then pat the fillets very dry before adding them to the buttermilk.
Excess water from thawed fish can dilute the buttermilk and make it more difficult for the coating to adhere.
The same general coating can work with other mild white fish, although cooking times may change depending on thickness.
Potential alternatives include cod, haddock, pollock, tilapia, or rockfish.
Thicker fillets will need more cooking time than thin flounder, so use a food thermometer rather than simply copying the same number of minutes.
Fried flounder is best immediately after cooking, but leftovers can still be saved.
Refrigerate cooked fish promptly in a covered container.
FDA guidance says seafood and other perishable foods should not remain at room temperature for more than 2 hours, or more than 1 hour when temperatures are above 90°F. U.S. Food and Drug Administration
USDA guidance for cooked fish indicates refrigerated cooked seafood can generally be used within 3–4 days, although the coating will be at its best much sooner. Ask USDA
Avoid the microwave if maintaining crispness is important.
For better texture, place leftover fish on a baking sheet or wire rack and reheat in a 375°F oven until hot and crisp.
An air fryer also works well for reheating breaded fish.
The exact time depends on the thickness of the fillet and how cold it is when reheating, so check it frequently rather than relying on one exact time.
The most common causes are oil that isn’t hot enough, overcrowding the skillet, excess moisture on the fish, or stacking the fillets after cooking.
Keep the oil close to 350°F and fry in batches.
Allow excess buttermilk to drip off before dredging, press the coating gently onto the fillet, and let the coated fish rest briefly before frying.
Handling it excessively after coating can also cause breading to loosen.
Yes, although the finished texture will be different.
You can use flour or breadcrumbs, but cornmeal provides the distinctive coarse crunch associated with Southern-style fried fish.
Yes.
You could use beaten egg or another wet coating, but buttermilk provides both flavor and excellent adhesion for the cornmeal mixture.
Choose a neutral cooking oil suitable for relatively high heat, such as vegetable, canola, or peanut oil.
The crust should be golden, and the fish should be opaque and flaky inside. For the safest and most reliable check, cook the thickest part to 145°F. U.S. Food and Drug Administration
