Ingredients You’ll Need
- 4 cod fillets (about 150g each), skinless
- 3 tablespoons olive oil
- 3 cloves garlic, minced (a key ingredient in many dishes, including decadent Garlic Butter Lobster Tails)
- Zest of 1 lemon
- 2 tablespoons fresh lemon juice
- 2 tablespoons fresh parsley, finely chopped
- 1 tablespoon fresh dill, finely chopped
- 1 teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 tablespoons unsalted butter, melted
- Lemon slices, for garnish
Tip: If your cod fillets vary in thickness, place the thicker ones at the edges of the baking dish — they’ll cook more evenly this way.
How to Make Baked Lemon Herb Cod
- Preheat your oven to 200°C (400°F). Line a 9×13 inch baking dish with aluminium foil, leaving enough overhang to fold over later. The foil makes cleanup effortless — you’ll simply lift it out and throw it away.
- Pat the cod fillets dry with kitchen paper. This step is crucial; excess moisture creates steam rather than allowing the fish to bake properly. The fillets should feel dry to the touch before you season them.
- In a small mixing bowl, combine the olive oil, minced garlic, lemon zest, lemon juice, parsley, dill, oregano, salt, and pepper. Stir until the herbs are evenly distributed — you’ll smell the bright, fresh aroma of lemon and herbs coming together.
- Place the cod fillets in the prepared baking dish, spacing them about 2cm apart. Pour the herb mixture evenly over each fillet, using a spoon to ensure every piece is well coated. The fish should glisten with the oil and herbs.
- Drizzle the melted butter over the top of the fillets. This adds richness and helps the fish develop a golden edge as it bakes. The butter will pool slightly around the fish.
- Fold the foil over the fish to create a sealed packet, then bake for 15-18 minutes. The exact time depends on the thickness of your fillets. You’ll know it’s done when the fish flakes easily with a fork and the flesh has turned from translucent to opaque white throughout. The aroma of lemon and herbs will fill your kitchen.
- Remove from the oven and carefully open the foil packet — watch out for the steam. Garnish with fresh lemon slices and an extra sprinkle of parsley if desired. Serve immediately while the fish is still warm and flaky.
Tips From My Kitchen
- Don’t skip patting the fish dry: Water is the enemy of a good sear or bake. When you remove excess moisture, the herb mixture clings better and the fish cooks rather than steams, giving you a firmer, more pleasant texture.
- Make the herb topping ahead of time: I often mix the olive oil, garlic, lemon zest, lemon juice, and herbs up to two days before. Store it in a sealed jar in the fridge, and when you’re ready, simply pour it over the fish. This saves precious minutes on busy evenings.
- Check for doneness with a fork: The best way to test cod is to insert a fork into the thickest part and twist gently. If the fish separates into large, moist flakes, it’s ready. Overcooked cod becomes dry and crumbly, so err on the side of slightly underdone — it will continue cooking from residual heat.
- Use a meat thermometer for precision: If you’re unsure, an instant-read thermometer inserted into the thickest part should read 63°C (145°F). This takes the guesswork out entirely and guarantees perfect results every time.
- Double the recipe for meal prep: This fish reheats beautifully — just store it in an airtight container in the fridge for up to three days. I like to make extra and flake it into salads or over rice for lunch the next day.
- Adjust cooking time for thicker fillets: If your cod is particularly thick (over 2.5cm), add 3-5 minutes to the baking time. For thinner pieces, check at the 12-minute mark to avoid overcooking.
Equipment You’ll Need
- 9×13 inch baking dish
- Aluminium foil
- Mixing bowls
- Sharp knife
- Microplane or zester
- Measuring spoons
- Kitchen tongs
Delicious Variations to Try
- Spicy Version: Add ½ teaspoon of red pepper flakes or a finely chopped fresh chilli to the herb mixture. The heat cuts through the richness of the butter beautifully and adds a lovely warmth without overwhelming the fish.
- Vegetarian/Vegan Option: Substitute the cod with thick slices of firm tofu or large portobello mushroom caps. Use a plant-based butter or extra olive oil instead of butter, and bake for the same amount of time until the tofu is golden and the mushrooms are tender.
- Different Protein: This herb mixture works wonderfully with salmon, haddock, or even chicken breast. For chicken, increase the baking time to 25-30 minutes and ensure the internal temperature reaches 74°C (165°F).
What to Serve With Baked Lemon Herb Cod
- Steamed green beans or asparagus — the bright green colour contrasts beautifully with the white fish
- Fluffy basmati rice or quinoa to soak up the lemony juices
- A simple side salad with a light vinaigrette
- Roasted baby potatoes tossed in olive oil and rosemary
