Ingredients for Baked Cod with Lemon and Garlic

Serves 4

• 4 cod fillets (about 6 oz / 170 g each) — fresh or fully thawed frozen cod
• 2 tablespoons extra virgin olive oil (or melted unsalted butter)
• 3 garlic cloves, finely minced
• 1 large lemon, zest and juice
• 1/2 teaspoon sea salt
• 1/4 teaspoon ground black pepper
• 1/4 teaspoon paprika (optional)
• 2 tablespoons fresh Italian parsley, chopped
• Lemon slices, for serving

Ingredient notes and swaps: For the best flavor and sustainability, choose wild-caught cod when available. If cod is not on hand, haddock, halibut, or tilapia work well with the same preparation. Swap olive oil for melted butter for a richer finish.

How to Make Baked Cod with Lemon and Garlic (Step-by-Step)

Step 1: Preheat the oven

Preheat the oven to 400°F (200°C). Line a baking sheet or shallow baking dish with parchment paper for easy cleanup.

Step 2: Prepare the lemon-garlic marinade

In a small bowl, whisk together olive oil, minced garlic, lemon zest, lemon juice, salt, pepper, and paprika if using. The citrus brightens the fish while the oil and garlic add savory depth.

Step 3: Ready the fillets

• Pat the cod fillets dry with paper towels to remove excess moisture—this helps seasoning stick and prevents steaming.
• Arrange the fillets in the prepared baking dish, leaving a little space between each piece.
• Generously spoon the lemon-garlic mixture over each fillet, coating the tops and sides.

Step 4: Bake

• Bake in the preheated oven for 12–15 minutes, depending on fillet thickness. The fish is done when it is opaque throughout and flakes easily with a fork.
• For a lightly golden finish, switch the oven to broil and broil for 1–2 minutes at the end—watch closely to avoid burning.

Step 5: Garnish and serve

• Sprinkle chopped parsley over the hot fillets.
• Add lemon slices to the plate for presentation and extra brightness.
• Serve immediately with your favorite sides.

Pro Tips for Perfect Baked Cod

• Don’t overcook: Cod cooks quickly—start checking at 12 minutes. Overcooked cod becomes dry and stringy.
• Use fresh citrus and garlic: Fresh lemon juice and freshly minced garlic provide better flavor than bottled alternatives.
• Season evenly: Pat fillets dry first, then season and marinate briefly for more consistent flavor.
• Try herbs: Dill, thyme, or basil complement lemon and garlic beautifully.
• Spice it up: A pinch of crushed red pepper flakes or a sprinkle of smoked paprika adds a subtle kick.

Freezing

FAQs
