Key Ingredients
To make this delicious Baked Cod with Mayo and Parmesan, you’ll need a handful of pantry staples and fresh cod fillets. Here are the main ingredients and the roles they play in creating that golden crust and bright, flaky fish:
- 4 cod fillets (about 6 ounces each): Firm, flaky fish that soaks up flavors and bakes beautifully under a creamy crust.
- 1/2 cup mayonnaise: Creates a rich, smooth base for the Parmesan topping and helps it adhere to the fish.
- 1/2 cup grated Parmesan cheese: Adds nutty, savory notes and crisps up into a golden, bubbly crust.
- 1 tablespoon Dijon mustard: Provides a subtle tang that balances the richness of the mayo and cheese.
- 2 tablespoons fresh lemon juice: Brightens the dish with citrus notes and tenderizes the cod ever so slightly.
- 1 teaspoon garlic powder: Infuses warm, aromatic garlic flavor without clumping or burning.
- 1 teaspoon onion powder: Offers a mild sweetness and depth without adding chunks.
- 1 teaspoon paprika: Lends a hint of smoky color and a gentle earthiness to the topping.
- 1/2 teaspoon black pepper: Delivers just enough heat to awaken the flavors.
- 1/2 teaspoon salt: Enhances and balances all the ingredients for a perfectly seasoned bite.
- 1 tablespoon chopped fresh parsley (for garnish): Sprinkles fresh herbal brightness over the finished fish.
How To Make Baked Cod with Mayo and Parmesan
Ready to transform those ingredients into a showstopping fish dinner? Follow these steps for perfectly baked cod crowned with a creamy, golden Parmesan layer that’s sure to impress.
1. Preheat your oven to 400°F (200°C) and prepare a baking dish by lightly greasing it with cooking spray or a drizzle of olive oil to prevent sticking.
2. In a mixing bowl, combine the mayonnaise, grated Parmesan cheese, Dijon mustard, fresh lemon juice, garlic powder, onion powder, paprika, black pepper, and salt. Stir until the mixture is fully smooth and every ingredient is evenly distributed.
3. Pat the cod fillets dry with paper towels to remove excess moisture—this step ensures a crisp crust when baking.
4. Arrange the cod fillets in a single layer in the prepared baking dish, leaving a little space around each piece for even heat circulation.
5. Spoon the mayo and Parmesan mixture generously over each fillet, spreading it into an even layer so the cheese can bubble and brown.
6. Bake in the preheated oven for 15–20 minutes, or until the fish is cooked through and flakes easily with a fork; the topping should be golden and bubbly.
7. Remove the baking dish from the oven and let the cod rest for 2–3 minutes—this brief rest helps the juices redistribute.
8. Garnish each fillet with the chopped fresh parsley, then serve immediately and enjoy your creamy, crunchy Baked Cod with Mayo and Parmesan!

This golden-crusted cod shines on its own, but pairing it thoughtfully elevates it to a complete, satisfying meal. Whether you’re hosting friends or cooking for two, these ideas add color, texture, and complementary flavors for a well-rounded dinner:

- Herb-Infused Rice: Fluff cooked jasmine or basmati rice with a bit of chopped parsley and lemon zest to soak up any leftover sauce on your plate.

Tips For Perfect Baked Cod with Mayo and Parmesan
Even though this baked cod is a breeze, these little tricks will help ensure you get that perfect golden crust and tender fish every time. From extra herbaceous boosts to meal prep ideas, let’s dive into some pro tips:
- For added flavor, mix in chopped fresh dill or chives with the mayonnaise mixture to introduce an herbal brightness that pairs beautifully with seafood.
- Serve with a side of steamed vegetables or a crisp green salad to round out the meal with color, crunch, and extra nutrients.
- Store any leftovers in an airtight container in the refrigerator for up to 2 days, then reheat gently in a warm oven to maintain the topping’s crisp texture.
How To Store It
Wondering what to do with any extra cod? Proper storage keeps your Baked Cod with Mayo and Parmesan just as delicious the next day, so you can enjoy every bite without waste:
- Refrigerate Promptly: Allow the cod to cool slightly, then transfer to an airtight container and store in the fridge for up to 2 days.
- Gentle Reheating: Warm leftover fillets in a 325°F (160°C) oven for about 8–10 minutes, loosely covered with foil to prevent drying.
- Freeze for Later: Wrap cooled, baked fillets individually in plastic wrap and place them in a freezer bag for up to 1 month; thaw overnight in the fridge before reheating.
- Avoid Microwaving: Microwaves can soften the crisp topping, so stick to oven reheating for the best texture and flavor retention.
Frequently Asked Questions
Here are answers to some common questions about making and enjoying Baked Cod with Mayo and Parmesan:
- How long does it take to prepare and cook this recipe?
A: Preparation takes about 10 minutes to gather ingredients, measure spices, and mix the mayo-Parmesan topping. Baking requires 15–20 minutes in a 400°F (200°C) oven, for a total time of around 25–30 minutes from start to finish.
- Can I substitute Greek yogurt for mayonnaise in the topping?
A: Yes. Use 1/2 cup plain Greek yogurt in place of mayonnaise for a lighter tang. The yogurt will create a slightly less rich crust but still holds the Parmesan and seasonings together well. Be sure to mix thoroughly so the texture remains creamy.
- How can I ensure the cod stays moist and doesn’t dry out?
A: Patting the fillets dry removes excess surface moisture for a crust, but do not overbake. Begin checking for doneness at 15 minutes by inserting a fork into the thickest part. The cod should flake apart easily yet remain opaque and slightly translucent at the center. Resting the fish for a couple of minutes after baking also helps retain juices.
- Can I use other types of fish or seafood instead of cod?
A: You can substitute halibut, haddock, pollock, or even thicker salmon fillets. Adjust baking time according to thickness: firmer, thicker fillets may need 18–22 minutes, while thinner fish will cook in 12–15 minutes. Always check flakiness with a fork.
- What side dishes pair well with this baked cod?
A: Steamed or roasted vegetables like asparagus, broccoli, green beans, or carrots complement the creamy topping. A simple tossed green salad with a lemon vinaigrette balances the richness, and a serving of rice, quinoa, or crusty bread helps soak up the flavorful juices.
- How should I store and reheat leftovers?
A: Store cooled leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place cod in a baking dish, cover loosely with foil, and warm in a 325°F (160°C) oven for 8–10 minutes until heated through. Avoid microwaving, which can make the topping soggy.
- Can I customize the seasoning or add fresh herbs to the mayo-Parmesan mixture?
A: Absolutely. Stir in 1–2 tablespoons chopped fresh dill, chives, or tarragon for herbal notes. A pinch of cayenne or a dash of smoked paprika can add heat and smokiness. Just maintain the 1:1 ratio of mayo to Parmesan to ensure proper consistency.
- Is it possible to assemble the dish ahead of time?
A: Yes. Prepare the cod and spread the mayo-Parmesan topping, then cover the baking dish with plastic wrap and refrigerate for up to 4 hours before baking. Allow the dish to sit at room temperature for 10–15 minutes before placing it in the preheated oven to ensure even cooking.
