I love a proper fried fish sandwich and that means the fish must be crispy, the bun toasted, and the sauce bright and flavorful. This version checks all those boxes: the cod is seasoned, dunked in a buttermilk-and-egg wash, and coated in a panko-and-flour mixture so it fries up crunchy while staying moist inside.
The homemade Cajun tartar sauce—mayonnaise, minced pickles, shallot, Dijon, Cajun seasoning, lemon, and a touch of hot sauce—adds a lively, tangy heat that complements the fish perfectly. Top it with melty American cheese and shredded lettuce on a buttered brioche bun, and you have a sandwich that’s simple to make and impossibly satisfying.

What Makes This Fried Fish Sandwich Special
- The coating stays crispy. A flour-and-panko combo gives a sturdy, craggy crust that resists sogginess when sauce is added.
- Seasoning in every layer. The fish, the wet mixture, and the dry breading are all seasoned so every bite is flavorful.
- Homemade Cajun tartar sauce. Bright, tangy, and lightly spicy, the sauce balances the richness of the fried fish and the buttery bun.
What Is the Best Fish for a Fried Fish Sandwich?
Cod is an excellent choice: mild in flavor, firm in texture, and flaky without falling apart. Other good options are haddock, pollock, halibut, and tilapia. Choose fillets of similar thickness so they cook evenly and don’t burn on the outside before the center is done.
Ingredient Highlights
The full, detailed ingredient list and exact amounts are in the recipe card below.
- Cod fillets: Use 4-ounce fillets for even cooking.
- American cheese: Optional but delicious—melts quickly over hot fish for creamy saltiness.
- Buttermilk and eggs: Create a thick wet bath that helps the breading adhere and tenderizes the fish.
- All-purpose flour and panko: The mix gives great crunch without overwhelming the fish.
- Brioche buns: Soft, buttery, slightly sweet—perfect for this sandwich.
- Neutral frying oil: Use vegetable, canola, or peanut oil with a high smoke point.
For the Cajun Tartar Sauce
Simple and bold: mayonnaise, minced pickles, shallot, Dijon mustard, Cajun seasoning, a pinch of sugar, capers (optional), lemon juice, and hot sauce. Mix and chill to develop flavor—this sauce will become a go-to condiment.
How to Make a Fried Fish Sandwich
Step 1: Make the Cajun tartar sauce. Combine all sauce ingredients and refrigerate while you prepare the fish so flavors meld.
Step 2: Pat the cod dry, season both sides with salt, pepper, and Old Bay, then dip into the buttermilk-and-egg mixture.
Step 3: Combine flour, panko, and seasonings. Press the breading firmly on both sides and along edges. Rest 5–10 minutes so the coating adheres.
Step 4: Heat 1–1½ inches of oil to about 350°F and fry for 3–4 minutes per side until golden and cooked through. Drain on a wire rack to preserve crispness.
Toast the buns: Melt butter in a skillet over medium heat and toast cut-side down until golden, about 2–3 minutes.
Step 6: Assemble Spread Cajun tartar sauce on both bun halves, add the crispy cod, place a slice of cheese on hot fish to melt, top with shredded lettuce, and crown with the top bun. Serve immediately with lemon wedges and extra sauce.
Expert Tips for Crispy Fried Fish Sandwiches
- Pat the fish dry. Moisture prevents the coating from sticking and can cause it to fall off during frying.
- Let the coated fish rest. A 5–10 minute rest helps the breading set so it adheres during frying.
- Maintain oil temperature. Keep oil around 350°F. Too cool = greasy; too hot = burnt coating before the fish is cooked.
- Fry in batches. Avoid overcrowding so the oil temperature recovers quickly between batches.
- Flip carefully. Allow a crisp crust to form before turning to avoid loosening the breading.
What to Serve with Fried Fish Sandwiches
Classic sides include French fries, onion rings, and sweet potato fries. Round out the meal with a simple potato salad, baked corn on the cob, or hush puppies. Offer lemon wedges, pickles, hot sauce, and extra tartar sauce for guests to customize.
How to Store and Reheat Fried Fish
Refrigerate: Cool the fish completely and store in an airtight container lined with paper towels for up to 3 days. Keep buns, lettuce, and tartar sauce separate. Do not store fully assembled sandwiches to avoid sogginess.
Reheat: Use a 375°F oven or air fryer to reheat until crisp and hot, about 6–10 minutes depending on thickness. Avoid microwaving—it softens the panko crust.
Recipe FAQs
If the fish is too wet, if the breading wasn’t pressed on firmly, or if the fish was moved too soon after entering the oil, the coating can separate. Pat fish dry, press the breading firmly, and let coated fillets rest 5–10 minutes before frying.
Greasy fish usually means the oil was too cool or the pan was overcrowded. Keep oil near 350°F and fry in small batches so the oil temperature recovers.
The breading should be golden and crisp. The fish should be opaque, flake easily with a fork, and register 145°F in the thickest part.
Yes. Place breaded fillets on a greased wire rack over a baking sheet, spray with cooking spray, and bake at 425°F for about 15–20 minutes, flipping once, until golden and cooked through.
Drain fried fish on a wire rack, toast the buns, and assemble just before serving. Placing lettuce beneath the fish creates a barrier between sauce and crust.
