Of course! The Filet-O-Fish is a McDonald’s classic—a mild fish patty with melty cheese and tangy tartar sauce on a soft steamed bun. This copycat recipe captures the essence while using fresh, simple ingredients.
Copycat McDonald’s Filet-O-Fish Sandwich
This recipe breaks down into four key parts: the tartar sauce, the fish patties, the assembly, and the “steamed” bun.
Part 1: Quick Tartar Sauce
(Make this first so flavors can meld.)
Ingredients:
· 1/2 cup mayonnaise
· 2 tbsp sweet pickle relish (or finely chopped dill pickles for a less sweet version)
· 1 tsp yellow mustard
· 1 tsp lemon juice
· 1 tsp finely minced onion (or 1/4 tsp onion powder)
· Pinch of salt and sugar
Method: Mix all ingredients in a small bowl. Cover and refrigerate until ready to use.
Part 2: The Fish Patties
Ingredients:
· 1 lb mild white fish fillets (like cod, pollock, or haddock), cut into 4 equal pieces
· 1 cup all-purpose flour
· 1 tsp salt, plus more for seasoning
· 1/2 tsp paprika
· 1/4 tsp garlic powder
· 1/4 tsp onion powder
· 2 large eggs, beaten
· 1 1/2 cups plain fine breadcrumbs or panko pulsed a few times in a food processor (the fine texture is key!)
· Neutral oil for frying (canola, vegetable, or peanut)
Method:
- Prep Fish: Pat fish pieces very dry. Season lightly with salt and pepper.
- Set up Breading Station: Use three shallow dishes.
· Dish 1: Mix flour, salt, paprika, garlic powder, and onion powder.
· Dish 2: Beat eggs with 1 tbsp water.
· Dish 3: Place breadcrumbs. - Bread: Dredge each fish piece in flour, shaking off excess. Dip in egg, letting excess drip off. Press firmly into breadcrumbs, coating completely. Place on a plate.
- Fry: In a large skillet, heat 1/2 inch of oil over medium-high heat (350-375°F/175-190°C). Fry patties for 3-4 minutes per side, until golden brown and cooked through. Drain on a wire rack set over a baking sheet (this keeps them crispy).
Part 3: The Assembly & “Steamed” Bun
Ingredients for 4 Sandwiches:
· 4 soft square hamburger buns (potato buns or classic white buns work best)
· 4 slices American cheese (it melts authentically!)
· Prepared tartar sauce
· Prepared fish patties
The “Steam” Method (The Secret!):
- Split the buns and place them, cut-side up, on a microwave-safe plate.
- Place a damp paper towel over the buns (not soaking wet, just wrung out).
- Microwave for 20-30 seconds, just until they are warm and soft. (Alternatively, you can wrap them in a damp cloth and warm them in a low oven for 5-10 minutes.)
Build the Sandwich:
- Spread about 1 tablespoon of tartar sauce on the top bun only.
- Place a slice of American cheese on the bottom bun.
- Place a hot fish patty directly onto the cheese (the heat will start to melt it).
- Cap with the top bun (tartar-side down).
Keys to Authenticity & Tips
- The Fish: The chain uses Alaskan pollock. Cod is the closest grocery store alternative in flavor and texture.
- The Cheese Half: Authentically, the cheese is placed on the bottom bun, under the hot fish. This is crucial for the proper melt and flavor experience.
- Breadcrumb Texture: Fine, dry breadcrumbs (like “plain” or “original”) give that signature coating, not large, fluffy panko.
- Fry Hot & Fast: Ensure your oil is hot enough before adding the fish. A too-cool pan will make the coating greasy.
- Don’t Skip the Steam: The soft, slightly sticky steamed bun is a defining characteristic. Toasting will give you a different, albeit delicious, sandwich.
Enjoy your homemade fast-food classic! It’s often tastier and certainly more satisfying to make yourself.
