- Nutrient-Dense: If you are looking for a healthy baked cod recipe, this version skips heavy batters in favor of a light, fiber-rich pea purée and omega-3-packed fish.

Ingredients You’ll Need
To get the best results for this lemon baked cod recipe, quality is key. Use the freshest fish available and high-quality extra virgin olive oil to lean into those Mediterranean flavors.
For the Cod
- Cod Fillets: Look for thick, loin-cut pieces (about 6 oz each) for even cooking.
- Panko Breadcrumbs: These provide a superior crunch compared to traditional fine breadcrumbs.
- Grated Parmesan Cheese: Use freshly grated if possible; it melts and browns better.
- Garlic: Two cloves, finely minced.
- Lemon Zest: The secret to that bright, aromatic pop.
- Fresh Herbs: A mix of parsley or dill works beautifully.
- Extra Virgin Olive Oil: To bind the crust and add richness.
- Salt and Black Pepper: To taste.
For the Spring Pea Purée
- Green Peas: Fresh are lovely in spring, but frozen peas work perfectly year-round.
- Garlic: One small clove, smashed.
- Lemon Juice: To balance the sweetness of the peas.
- Olive Oil: For a silky, emulsified texture.
- Fresh Mint (Optional): Highly recommended for a classic Mediterranean pairing.
How to Make Sheet Pan Baked Cod (Step-by-Step)
Follow these steps to ensure your easy cod sheet pan dinner turns out restaurant-quality every time.
Step 1: Prep the Oven and Ingredients
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper. Use a paper towel to pat the cod fillets completely dry. This is the most important step for ensuring the crust sticks and the fish does not steam.
Step 2: Make the Parmesan Crust
In a small bowl, combine the Panko, grated Parmesan, minced garlic, lemon zest, and chopped herbs. Drizzle in 1 to 2 tablespoons of olive oil and stir until the mixture looks like wet sand.
Step 3: Assemble the Sheet Pan
Place the cod fillets on the prepared tray. Season lightly with salt and pepper. Spoon the Parmesan mixture generously over the top of each fillet, pressing down firmly so it adheres.
Step 4: Bake to Perfection
Slide the tray into the oven. Bake for 12–15 minutes (depending on thickness). For an extra-golden finish, you can turn on the broiler for the last 60 seconds—just watch it closely.
Step 5: Make the Pea Purée
While the fish bakes, boil the peas for 2–3 minutes until bright green. Drain and add to a blender with garlic, lemon juice, mint, and olive oil. Pulse until smooth but still slightly textured.
Step 6: Plate and Serve
Spoon a generous dollop of the pea purée onto each plate. Use an offset spatula to carefully place the cod on top. Garnish with a fresh lemon wedge and a drizzle of oil.

Notes
1. The “Dry Fish” Rule
The biggest mistake home cooks make with baked fish is leaving moisture on the surface. If the cod is wet, the steam will make the parmesan crust soggy. Use a heavy-duty paper towel to press firmly on both sides of the fillet until the surface is tacky, not slippery.2. Pea Purée Consistency
If your purée feels too thick or “grainy,” add 1 tablespoon of the pea-boiling water or warm vegetable broth at a time while the blender is running. For an ultra-fine, restaurant-style texture, you can pass the purée through a fine-mesh sieve, though the rustic texture is more traditional for home-style Mediterranean cooking.3. Scaling the Recipe
If you are cooking for a larger group, do not crowd the sheet pan. Leave at least 2 inches of space between each fillet. If the fish are too close together, they will steam each other rather than roasting, which prevents the crust from getting that signature “crunch.”4. Choosing the Best Cod
While Atlantic and Pacific cod are both excellent, Pacific cod is often slightly firmer, while Atlantic cod is sweeter and has larger flakes. If you prefer a very meaty texture, ask your fishmonger for “loin” cuts rather than “tail” cuts, as they are thicker and cook more evenly.5. Flavor Upgrades
- Herb Swap: If you do not like mint in your peas, try fresh basil or tarragon.
- Nutty Crust: Add 1 tablespoon of finely crushed pine nuts to the parmesan mixture for an extra layer of Mediterranean flavor.
- Acid Balance: If the dish feels “flat,” finish the plated fish with a tiny pinch of flaky sea salt (like Maldon) and an extra squeeze of fresh lemon juice.
Tips for the Best Lemon Parmesan Cod
- Do Not Overbake: Cod is done when it reaches an internal temperature of 145°F (63°C). It should flake easily with a fork but still look moist in the center.
- The Zest Rule: Only zest the yellow part of the lemon peel. The white pith underneath is bitter and can ruin the delicate flavor of the fish.
- Toasting Hack: If you want an ultra-deep gold color, lightly toast the Panko in a dry pan for 2 minutes before mixing it with the cheese.
- Uniformity: Try to choose fillets of similar thickness so they all finish cooking at the same time.

FAQs
Can I use frozen cod? Yes. Just ensure it is completely thawed in the refrigerator overnight and patted dry with paper towels to remove excess moisture.
How do I know when the cod is done? The fish will turn from translucent to opaque and will flake (separate into natural segments) when pressed with a fork.
Can I skip the pea purée? You can, but the cod with pea puree combination is what makes this dish feel like a gourmet meal. If you skip it, try serving the fish over a bed of sautéed spinach
