Cornflake Crusted Fish and Chips

This recipe is basically the grown-up version of eating cereal for dinner, except now you can claim it’s sophisticated because it involves actual cooking.

The cornflake coating creates this ridiculously satisfying crunch that makes regular breadcrumbs seem boring and uninspired.

You’ll get perfectly flaky fish inside with a golden, crispy exterior that sounds like a symphony when you bite into it.

The best part is watching people’s faces when they realize you’ve turned breakfast cereal into the star of dinner.

This is the kind of recipe that makes you feel like a culinary genius while using ingredients you probably already have in your pantry.

Plus, it’s ready in 20 minutes, which means you can go from “what’s for dinner?” panic to looking like you planned this all along.

Ingredients

For tartar sauce

1 /2 cup mayonnaise
2 Tbsp. pickle relish
1 Tbsp. diced onion

For fish

1 /2 cup all-purpose flour
Kosher salt and freshly ground pepper
2 eggs
3 cups cornflakes, well crushed
1 lb. cod, tilapia, or other white fish, cut into small fillets

Instructions

Prepare the tartar sauce

1 Combine 1/2 cup mayonnaise, 2 tablespoons pickle relish, and 1 tablespoon diced onion in a small bowl. Mix thoroughly until well combined and set aside. This sauce actually improves as it sits, allowing the flavors to meld together while you prepare the fish.

Set up your breading station

2 Preheat your oven to 500°F (260°C) and line a baking sheet with aluminum foil for easy cleanup. Place a wire rack on top of the foil-lined baking sheet – this is crucial for allowing air circulation around the fish, ensuring the bottom stays crispy instead of soggy.
3 Pour 1/2 cup all-purpose flour onto a small tray or wide bowl and season generously with at least 1 tablespoon kosher salt and freshly ground pepper to taste. The flour mixture should be well-seasoned since this is your first layer of flavor.
4 In a second wide bowl, beat 2 eggs with 3 tablespoons water until completely smooth. The water helps thin the egg mixture slightly, making it easier to coat the fish evenly without clumping.
5 Add 3 cups well-crushed cornflakes to a third tray or shallow dish. For best results, crush the cornflakes using a food processor or by placing them in a sealed bag and rolling with a rolling pin until they’re broken into small, uniform pieces but not powdered.

Bread and bake the fish

6 Pat the fish fillets completely dry with paper towels and season both sides generously with kosher salt and freshly ground pepper. Moisture is the enemy of crispy coating, so don’t skip this step.
7 Working with one fillet at a time, dredge first in the seasoned flour, shaking off excess. Next, dip into the egg mixture, allowing excess to drip off. Finally, roll thoroughly in the crushed cornflakes, pressing gently to help the coating adhere. Place each coated fillet on the wire rack.
8 Bake in the preheated 500°F (260°C) oven for 10-12 minutes until the fish is just cooked through and flaky when tested with a fork. The internal temperature should reach 145°F (63°C) and the coating should be golden brown and crispy.

Air fryer alternative

9 To make in an air fryer, arrange as many fillets as will fit comfortably in the basket without overcrowding. Cook at 400°F (204°C) for 4-6 minutes, turning halfway through cooking time for even browning.

Excellent for kids’ parties since the familiar cornflake coating appeals to young palates. Great for Lenten meals or healthy eating goals when you want comfort food that fits your nutritional needs.

Pro Tips and Troubleshooting

Professional Techniques

Pat fish completely dry before seasoning – excess moisture prevents proper coating adhesion and creates soggy results. Season each layer (flour, fish, and coating) rather than relying on just one seasoning step for maximum flavor impact. Use the wire rack without exception – this single step makes the difference between restaurant-quality crispy coating and disappointing soggy fish.

Common Mistakes and Solutions

Overcrowding the pan leads to uneven cooking and steaming instead of crisping. Cook in batches if necessary, keeping finished pieces warm in a 200°F (93°C) oven. Skipping the flour step results in coating that falls off during cooking. Not preheating the oven fully to 500°F (260°C) prevents proper browning and crisping.

Storage and Reheating

Refrigerate leftovers for up to 3 days in airtight containers. Reheat in a 400°F (204°C) oven for 5-7 minutes to restore crispiness – never use the microwave, which makes coating soggy. Tartar sauce keeps for up to 1 week refrigerated.

Make-Ahead Strategies

Bread the fish up to 4 hours ahead and refrigerate on the wire rack, covered with plastic wrap. Make tartar sauce up to 3 days ahead for better flavor development. Crush cornflakes in large batches and store in airtight containers for quick future meals.

Recipe Scaling

Double the recipe easily by using two baking sheets and wire racks. Cooking time remains the same – just rotate pans halfway through for even browning. Tartar sauce scales perfectly and actually improves when made in larger batches.

This cornflake-crusted fish delivers all the satisfaction of traditional fish and chips with a fraction of the oil and mess, proving that sometimes the most brilliant culinary innovations come from thinking outside the box – or in this case, outside the breadcrumb container.
