Breaded Baked Cod
Crispy Panko-Crusted Cod with Lemon
This foolproof technique gives you restaurant-quality fish at home — tender cod fillets wrapped in a golden, crunchy coating that actually stays put. The secret is in the three-step breading process and a touch of mayo that helps everything bind together beautifully.
White fish like cod walks a narrow line in the kitchen — it needs enough heat to develop a proper crust, but just a few minutes too long and you're left with something that resembles cardboard. This panko-crusted version solves that problem by creating a protective armor of golden crumbs that insulates the fish while adding serious textural contrast.
The three-step breading process isn't just restaurant showmanship — each layer serves a purpose. The flour creates grip, the seasoned egg mixture acts as glue, and the panko forms that coveted crunchy shell. But the real secret ingredient here is mayonnaise mixed into the egg wash. It sounds unconventional, but mayo is essentially eggs and oil emulsified together, which means it helps the coating adhere better while adding richness that keeps the fish moist.
This technique works beautifully with any white fish — halibut, mahi-mahi, or even tilapia all respond well to this treatment. The coating stays put through baking, emerging golden and crispy while the fish inside remains flaky and tender. It's the kind of reliable method that turns a simple weeknight dinner into something that looks like you ordered it from your favorite seafood restaurant.
Ingredients
- 1½ lbwhite fish fillets (cod, haddock, or similar firm white fish)
- kosher salt
- freshly ground black pepper
- 1 cuppanko breadcrumbs
- 2 tbspfresh parsley, finely chopped
- ¼ cupall-purpose flour
- 2 largelarge eggs
- 1 tspCajun seasoning
- 2 tbspmayonnaise
- 1 fresh lemon
- tartar sauce(optional)
Instructions
- Preheat your oven to 425°F and let it come to full temperature while you prep the fish.
- Line a large rimmed baking sheet with foil or parchment paper, then spray generously with cooking spray. This prevents sticking and makes cleanup easier.
- Cut the fish into 6-ounce portions — about 4-5 inches long and evenly sized so they cook at the same rate.
- Season both sides of each fillet with salt and pepper, pressing gently so the seasoning adheres to the surface.
- Mix the panko and chopped parsley in a wide, shallow bowl. The parsley adds color and fresh flavor to the crust.
- Place the flour in a separate shallow bowl for the first coating station.
- In a third bowl, whisk together the eggs, Cajun seasoning, and mayonnaise until smooth. The mayo helps the coating stick and adds richness.
- Dredge each piece of fish in flour, shaking off any excess. The flour creates a base layer that helps the egg mixture cling.
- Dip the floured fish into the egg mixture, letting excess drip off, then press into the panko mixture on both sides. Really press to make sure the coating adheres well.
- Place the breaded fillets on your prepared baking sheet with space between each piece for even browning.
- Bake for 16-20 minutes until the coating is golden brown and the fish flakes easily when tested with a fork at the thickest part.⏱ 20 min
- While the fish bakes, cut the lemon into 4 wedges for serving.
- Serve immediately with lemon wedges for squeezing and tartar sauce on the side if desired.
Tips & Tricks
- Pat the fish completely dry with paper towels before seasoning — any surface moisture will prevent the flour from sticking properly.
- Press the panko coating firmly with your palms after dredging to ensure it adheres; loose coating will fall off during baking.
- Check doneness by inserting a fork at the thickest part — the fish should flake easily and read 145°F on an instant-read thermometer.
- If your panko seems too fine, pulse it briefly in a food processor to create more varied-sized crumbs for better texture.
- Space the fillets at least an inch apart on the baking sheet so steam doesn't build up and soften the coating.
Frequently Asked Questions
Can I use regular breadcrumbs instead of panko?
Regular breadcrumbs will work but won't give you the same light, crispy texture. Panko breadcrumbs are larger and create more air pockets, which means better crunch. If you only have regular breadcrumbs, the coating will be denser but still tasty.
What if I don't have Cajun seasoning?
Mix together 1/2 teaspoon each of paprika, garlic powder, and onion powder with a pinch of cayenne pepper. You can also just use additional salt and pepper if you prefer a milder flavor.
How do I know when the fish is fully cooked?
The coating should be golden brown and the fish should flake easily when tested with a fork at the thickest part. Internal temperature should reach 145°F, but the flake test is more reliable than a thermometer for thin fillets.
Can I make this ahead of time?
You can bread the fish up to 4 hours ahead and refrigerate on the baking sheet, covered. Don't freeze breaded raw fish as it affects the texture. Bake directly from the refrigerator, adding 2-3 extra minutes to the cooking time.
