McDonald’s Filet-O-Fish Copycat

This McDonald’s Filet-O-Fish Copycat delivers bold flavor with minimal effort, making it perfect for busy weeknights or relaxed weekends. The crispy golden coating paired with tender cod creates a satisfying crunch in every bite. It has that familiar fast-food comfort you expect from a Filet-O-Fish but with even better texture and flavor. This is the kind of sandwich that makes you skip the drive-thru and cook it at home instead.

What makes this version better is the seasoned double-coating method, which builds flavor instead of rushing it. The fish gets dredged in seasoned flour before being dipped in a light batter that fries up golden and crispy. Each step keeps the cod tender while creating that signature crunchy crust. For a full meal, serve it alongside classic sides like Creamy Baked Mac and Cheese Recipe, Smokin’ DUI Fries, and a crisp Southern Coleslaw for balanced texture and flavor.

Instructions

Step 1: Prep the Base

Heat vegetable oil in a heavy pot to 350°F. Set up two bowls — one for the seasoned flour dredge and one for the wet batter. Pat the cod fillets dry and trim to bun size if needed.

Step 2: Build the Flavor

Season the dry flour with Creole seasoning, salt, and pepper. In a separate bowl, combine flour, garlic powder, onion powder, Creole seasoning, salt, and pepper. Slowly whisk in cold unflavored seltzer water until the batter reaches a thick pancake-like consistency.

Step 3: Cook and Control

Dredge each fillet in the dry flour first, shaking off excess. Dip into the wet batter and let the extra drip off. Carefully lower into the hot oil, placing away from you. Fry 3–4 minutes per side until golden brown and crispy. Maintain oil temperature between 350–370°F.

Step 4: Finish and Serve

Remove fish and drain on a rack. Immediately place a slice of cheese on each hot fillet so it melts slightly. Lightly toast brioche buns if desired. Assemble and serve with your favorite tartar sauce.

Tips & Tricks

• Use cold seltzer water for extra crispiness.
• Do not overcrowd the oil — fry in batches.
• Let excess batter drip off before frying to avoid heavy coating.
• If browning too fast, slightly reduce heat to maintain even cooking.

Variations

Spicy Cajun: Add cayenne pepper or hot sauce to the batter.
Southern Style: Swap seltzer for cold buttermilk for a thicker crust.
Air Fryer Version: Spray battered fish lightly with oil and cook at 400°F for 10–12 minutes, flipping halfway.
