This recipe was kind of a desperate fluke. Back in 2012 (yikes, that’s a while ago!) – on the day hurricane Sandy was slated to tear apart my home we frantically tore through our fridge and freezer in search of things we had to make that minute in case we lost power (which we did). Amist the stacks of Tupperware, I found a bag of walnuts in the fridge, one lemon on the verge of turning and huge filet of frozen cod. So, at 10am, I made us lemon crusted cod which we ate for breakfast. It was delicious, and has stuck with our dinner (more suitable) repertoire since.
The cod is perfectly flaky and buttery enough to melt in your mouth and the walnut crust gives each bite the perfect crunch. Plus, the addition of the lemon pepper adds the perfect zing to the more mild flavor of the fish. Even if you aren’t preparing for a massive hurricane, you should definitely make this.
Just maybe not for breakfast. Unless you are trading your coffee for white wine, and in that case, all bets are off.
Step by Step Guide to Making Lemon and Walnut Crusted Cod
Preparation:
- Preheat the oven to 425°F (220°C). Lightly grease a baking pan.
- Rinse cod fillets under cold water and pat dry with paper towels. Place the fillets in the prepared baking pan.
- Evenly drizzle lemon juice over the cod fillets.
Creating the Crust:
- In a small mixing bowl, combine the finely chopped parsley, lemon zest, breadcrumbs, and finely chopped walnuts. Season the mixture with a dash of salt and lemon pepper to enhance the flavor.
- Pour the melted butter into the walnut and breadcrumb mixture. Stir until the ingredients are well combined and the mixture becomes crumbly.
Applying the Crust and Baking:
- Spread about 2 tablespoons of the walnut mixture over one side of each cod fillet, pressing slightly to adhere.
- Place the baking pan in the preheated oven and bake for 15 minutes, or until the cod is opaque, flakes easily with a fork, and the crust is golden brown.
Recipe Notes:
- Ensure your walnuts are finely chopped for a consistent crust.
- For a crispier crust, broil the fish for an additional 1-2 minutes at the end of baking.
- Lemon pepper seasoning adds an extra zing, adjust according to your taste.
- Serve with a wedge of lemon for an extra burst of citrus.

Frequently Asked Questions
Can I use a different type of fish instead of cod?
Yes, you can substitute cod with other flaky white fish like haddock or tilapia, but adjust the cooking time if the fillets are thicker or thinner.
What can I use if I don’t have lemon pepper for the crust?
If you don’t have lemon pepper, you can use regular black pepper and add a bit more lemon zest to maintain the citrus flavor.
How finely should I chop the walnuts for the crust?
Chop the walnuts finely enough to mix well with the breadcrumbs, ensuring they provide a nice crunch without being too large.

Sprinkling a bit of fresh thyme into the walnut crust adds a nice earthy note that pairs surprisingly well with the lemony flavor.
Made this for a quiet Sunday dinner, and it was just right. The walnut crust added such a nice texture contrast to the cod. Big ups!!
Simple and great.
I bake cod 2 to 3 times a month and this is my husband and my favorite recipe we have tried. Enjoyed eating and easy to prepare.
Glad to hear that!
This was fantastic. Made it with haddock instead of cod but it was perfect. Browned so nicely and the walnuts gave it a great crunch. Didn’t have fresh parsley so substituted dried dill and it was great.
That’s great to hear Claudia! Haddock sounds like the perfect replacement for the cod. Thanks for sharing!
Thank you for this recipe! I didn’t have bread crumbs so I substituted potato pancake mix and it was delicious!
Excellent recipe. I made this tonight and didn’t change a thing. Will definitely make again.
Excellent recipe! The topping stuck and browned perfectly. It was so delicious and transformed my frozen bland cod filets.
You mention the ing. lemon-pepper in your prose, but not in the recipe. Does it belong in the recipe?
I made this last night, and it honestly turned out perfectly. Thank you!
