Essential Ingredients

Here’s everything you’ll need to make your Golden Cod Sandwich with Creamy Homemade Tartar Sauce.

For the Cod:

• 4 cod fillets (about 4–6 ounces each)
• 1 cup all-purpose flour
• 2 large eggs, beaten
• 1 cup panko breadcrumbs (for extra crunch)
• 1 teaspoon garlic powder
• ½ teaspoon paprika
• Salt and black pepper to taste
• Vegetable oil for frying

For the Homemade Tartar Sauce:

• 1 cup mayonnaise
• 2 tablespoons finely chopped dill pickles or dill relish
• 1 tablespoon lemon juice
• 1 tablespoon chopped capers (optional for extra tang)
• 2 teaspoons Dijon mustard
• 1 tablespoon finely chopped parsley
• 1 teaspoon onion powder or 1 tablespoon finely minced onion
• Salt and pepper to taste

For the Sandwich Assembly:

• 4 sandwich buns or brioche rolls
• 1 cup shredded lettuce
• 4 slices of tomato
• 4 slices of cheddar or American cheese (optional)

Ingredient Substitutions and Variations:

• Fish: You can replace cod with haddock, tilapia, or pollock.
• Breadcrumbs: Use crushed cornflakes or regular breadcrumbs if panko isn’t available.
• Tartar Sauce: Substitute Greek yogurt for half the mayo for a lighter version.
• Gluten-Free Option: Use gluten-free flour and breadcrumbs.
• Extra Flavor: Add a pinch of cayenne pepper or Old Bay seasoning to the coating mix.

Step-by-Step Instructions

Step 1: Prepare the Fish

Pat your cod fillets dry using paper towels. This helps the coating stick better and ensures a crisp finish. Season both sides of the fish with salt, pepper, and paprika.

Step 2: Set Up Your Breading Station

You’ll need three shallow bowls:

• One with flour mixed with garlic powder and a pinch of salt.
• One with the beaten eggs.
• One with the panko breadcrumbs.

Dip each piece of cod in the flour first, then the egg, and finally coat it evenly with breadcrumbs. Lightly press the breadcrumbs onto the fish so they stick well.

Step 3: Fry the Cod

Heat about ½ inch of oil in a large skillet over medium heat. You’ll know it’s ready when a breadcrumb dropped in sizzles instantly. Gently lay the fish fillets in the pan, being careful not to overcrowd them.

Cook each fillet for 3–4 minutes per side, or until golden brown and crisp. The internal temperature should reach 145°F. Once done, transfer the cod to a plate lined with paper towels to drain excess oil.

Tip: Keep the cooked fillets warm in a 200°F oven while you prepare the rest.

Make the Creamy Homemade Tartar Sauce

In a small bowl, mix together the mayonnaise, chopped pickles, lemon juice, mustard, parsley, onion powder, and capers if using. Add salt and pepper to taste.

Refrigerate for at least 20 minutes to let the flavors blend together. This step makes the sauce richer and creamier.

Pro Tip: Make the tartar sauce ahead of time and store it in the fridge. The flavor improves as it sits.

How to Assemble the Sandwich

1. Toast the Buns: Lightly butter and toast the sandwich buns until golden. This helps them hold up better to the sauce and fish.
2. Layer the Ingredients:
   • Spread a generous spoonful of tartar sauce on the bottom bun.
   • Add a crispy cod fillet.
   • Top with shredded lettuce and a slice of tomato.
   • Add cheese if desired.
   • Finish with another layer of tartar sauce on the top bun.
3. Serve Immediately: The sandwich is best enjoyed while the fish is still warm and crispy.

Presentation Tip: Serve with lemon wedges on the side for an extra burst of freshness. Add a handful of fries or a side salad for a complete meal.

Storage and Make-Ahead Tips

• Storing Leftovers: Keep leftover cooked fish in an airtight container in the refrigerator for up to 2 days.
• Reheating: Reheat in an oven or air fryer at 350°F for 10 minutes to keep the coating crispy. Avoid microwaving, as it can make the fish soggy.
• Tartar Sauce: Store in a sealed container in the fridge for up to a week. Stir before using again.
• Make-Ahead: You can bread the fish fillets ahead of time and refrigerate them for up to 4 hours before frying.

Recipe Variations

• Spicy Cod Sandwich: Add a dash of hot sauce or a teaspoon of Cajun seasoning to the batter for a kick.
• Baked Version: Instead of frying, bake the breaded cod at 400°F for 15–18 minutes, flipping halfway through.
• Lemon Herb Cod: Mix lemon zest and dried herbs into the breadcrumb coating for a bright flavor.
• Fish Tacos: Cut the cod into smaller pieces and serve in tortillas with tartar sauce and shredded cabbage.
• Healthier Twist: Use an air fryer instead of oil for a lower-fat version that’s still crispy and delicious.

Health Benefits

Plus, making it at home lets you control the ingredients and skip the unnecessary additives often found in fast-food versions.
