Ingredients You’ll Need
The beauty of this recipe lies in its simplicity. Most of these ingredients are already in your kitchen.
| Ingredient | Quantity | Notes |
|---|---|---|
| Cod fillets | 4 (about 1½ lbs / 680g) | Fresh or frozen (thawed) cod works well |
| Mayonnaise | ½ cup | Use light mayo for a lower-calorie version |
| Parmesan cheese | ½ cup (grated) | Freshly grated gives the best flavor |
| Lemon juice | 1 tbsp | Freshly squeezed preferred |
| Garlic powder | 1 tsp | Adds a subtle, aromatic flavor |
| Salt | ½ tsp | Adjust to taste |
| Black pepper | ¼ tsp | Freshly ground for extra flavor |
| Fresh parsley | 1 tbsp (chopped) | For garnish and color |
Step-by-Step Instructions
Let’s walk through how to make this dish flawlessly from start to finish.
Step 1: Preheat the Oven
Set your oven to 400°F (200°C) and position the rack in the middle.
Preheating ensures even cooking and helps the topping develop that golden crust.
Step 2: Prepare the Baking Dish
Lightly grease a baking dish or line it with parchment paper for easier cleanup. Place the cod fillets in a single layer, making sure they aren’t overlapping.
Step 3: Create the Creamy Coating
In a mixing bowl, combine:
- ½ cup mayonnaise
- ½ cup grated Parmesan
- 1 tablespoon lemon juice
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
Stir until the mixture is smooth and well combined. It should have a thick, creamy consistency.
Step 4: Spread and Coat
Using a spoon or spatula, spread the mixture evenly over the top of each cod fillet. Don’t coat the bottom — you want the mayo-Parmesan blend to bake and crisp beautifully on top.
Step 5: Bake to Perfection
Bake uncovered for 12–15 minutes, depending on the thickness of your fillets. The fish is done when:
- The top is lightly golden and bubbling
- The flesh flakes easily with a fork
- Internal temperature reaches 145°F (63°C)
Step 6: Garnish and Serve
Remove from the oven, rest for 2 minutes, then garnish with fresh chopped parsley. Serve warm with your favorite sides.
Chef’s Expert Tips
👩🍳 1. Use Fresh Ingredients:
Freshly squeezed lemon juice and real Parmesan (not the powdered kind) make a world of difference.
🔥 2. Don’t Overbake:
Cod cooks quickly; overbaking can make it dry. Remove it as soon as it flakes easily.
🥣 3. Adjust the Coating:
If you prefer extra crunch, sprinkle a tablespoon of breadcrumbs over the top before baking.
🧈 4. Enhance the Flavor:
Add a pinch of paprika or dried dill for a hint of smokiness or freshness.
🍋 5. Balance with Acidity:
A light squeeze of lemon before serving enhances the creamy topping beautifully.

Frequently Asked Questions
1. Can I use a different fish instead of cod?
Yes. Haddock, tilapia, or halibut make great substitutes with similar texture and flavor.

You can mix the mayo-Parmesan topping up to 24 hours in advance and refrigerate it until needed.

Absolutely! Cook at 380°F (193°C) for about 10–12 minutes until golden and flaky.
4. Can I make it dairy-free?
Yes, substitute Parmesan with nutritional yeast for a dairy-free, umami flavor.
5. How do I know my cod is fully cooked?
It should be opaque and easily flake apart with a fork. A food thermometer should read 145°F (63°C) in the center.
6. What type of mayonnaise works best?
Regular or light mayo both work. Avoid fat-free versions, as they don’t brown or taste as rich.
7. Can I add vegetables to the same pan?
Yes! Toss zucchini, bell peppers, or cherry tomatoes with olive oil and roast them alongside the cod for a one-pan meal.
