- 1/2 cup panko breadcrumbs
- 1/2 cup finely grated Parmesan
- 1 tsp garlic powder
- 1 tsp Italian seasoning (or dried oregano)
- 1/2 tsp kosher salt (plus more to taste)
- 1/4 tsp black pepper

How to make oven-baked cod with Parmesan crust
1) Heat the oven. Preheat to 425°F. Lightly oil a sheet pan or line with parchment for easy cleanup.
2) Mix the crust. In a bowl, combine panko, Parmesan, garlic powder, Italian seasoning, salt, pepper, and lemon zest. Drizzle in olive oil and mix until the crumbs look evenly moistened.
3) Prep the fish. Pat cod very dry (this helps the crust stick). Place fillets on the pan and season lightly with salt and pepper.
4) Add the binder. In a small bowl, stir together mayonnaise and Dijon (if using). Spread a thin layer over the top of each fillet.
5) Press on the topping. Mound the Parmesan panko mixture on top of each piece of cod and gently press so it adheres.
6) Bake. Bake 10–14 minutes, depending on thickness, until the fish flakes easily and the topping is golden. For extra browning, broil 1–2 minutes at the end, watching closely.
7) Finish and serve. Sprinkle with parsley and squeeze fresh lemon juice over the top. Serve right away.
How to know when cod is done
- Flake test: The fish should flake easily with a fork and look opaque.
- Temperature: Aim for 135–140°F in the thickest part; it will carry over slightly as it rests.
- Timing: Most cod fillets bake in 10–14 minutes at 425°F. Very thick pieces may take a couple extra minutes.
Tips for the crispiest Parmesan crust
- Dry the fish well before adding the binder and crumbs.
- Use finely grated Parmesan so it melts and browns evenly.
- Don’t skimp on the oil in the crumb mixture; it helps the topping crisp in the oven.
- Broil briefly at the end for deeper color—just keep a close eye on it.
Serving ideas
- Roasted asparagus, broccoli, or green beans
- Garlic mashed potatoes or roasted baby potatoes
- Rice pilaf or buttered orzo
- Simple arugula salad with lemon vinaigrette
Substitutions and variations
- Fish: Swap cod for haddock, pollock, or halibut (adjust bake time for thickness).
- Gluten-free: Use gluten-free panko.
- Extra flavor: Add smoked paprika or a pinch of red pepper flakes to the crust.
- No mayo: Use Greek yogurt or a little melted butter; just aim for a thin sticky layer to hold crumbs.
Storage and reheating
- Refrigerate: Store leftovers in an airtight container up to 2 days.
- Reheat: Warm on a sheet pan at 375°F for 8–10 minutes to re-crisp the topping. Avoid the microwave if you want the crust crunchy.
