Lemon Butter Baked Cod

Lemon Butter Baked Cod delivers tender, flaky cod fillets baked to perfection in a pool of garlicky lemon butter sauce. This elegant yet effortless dish delivers restaurant-quality results with minimal prep and hands-off cooking — perfect for busy weeknights or impressive dinner parties. Where Pan-Seared Cod relies on precise dry-heat searing and immediate serving to protect its texture, this recipe takes a genuinely different, gentler approach: the fish bakes directly in a pool of melted butter, lemon juice, and garlic, meaning the cooking liquid itself does much of the flavor work while the oven's even, surrounding heat cooks the fillets through without requiring the constant attention undisturbed searing demands. Arranging the fillets snugly in the baking dish ensures the butter sauce actually pools around them rather than spreading thin across a larger dish, keeping the fish genuinely submerged in flavor throughout baking. Thin lemon slices placed directly on top of each fillet contribute both visual presentation and further citrus aromatics as they bake alongside the fish. The result is a dish that's genuinely low-effort and high-reward — flaky, moist cod in a bright, garlicky butter sauce with almost no active cooking required.

Ingredients Method Notes

Ingredients

For the Cod

800 g cod fillets 4 portions, about 200g each
10 g fine sea salt
4 g freshly ground black pepper
3 g smoked paprika

For the Lemon Butter Sauce

80 g unsalted butter melted
45 ml lemon juice
6 garlic cloves minced

For Garnish

1 lemon thinly sliced
30 g fresh parsley chopped

Method

Preheat and Prepare

Preheat your oven to 200°C (400°F). Place the 800g of cod fillets in a baking dish in a single layer, ensuring they fit snugly so the butter will pool around them.

Make the Lemon Butter Sauce

In a small bowl, combine the 80g of melted butter, 45ml of lemon juice, and minced garlic cloves. Whisk together until well incorporated.

Season the Fish

Season each cod fillet evenly with the 10g of salt, 4g of black pepper, and 3g of smoked paprika. Pour the lemon butter mixture over the fish, ensuring each piece is well coated.

Add Lemon Slices

Arrange the thinly sliced lemon rounds on top of each fillet, placing 2-3 slices per portion for beautiful presentation and extra citrus flavor.

Bake Until Flaky

Bake uncovered for 15-18 minutes until the fish flakes easily with a fork and is opaque throughout. The top should dry slightly while the bottom stays moist in the butter.

Garnish and Serve

Spoon the pan juices over each fillet, garnish with the 30g of chopped fresh parsley, and serve immediately while hot.

Notes

Arranging the fillets snugly in the baking dish is a deliberate spatial choice rather than a space-saving one. A dish that's too large for the amount of fish and butter spreads the sauce thin across the bottom, meaning less of it actually surrounds and bastes the fillets during baking — a snugly fitted dish keeps the butter genuinely pooled around the fish throughout the cooking time.

The lemon slices on top of each fillet contribute more than visual appeal. As they bake, they release additional citrus oils and juice directly onto the fish's surface, layering a second, more concentrated citrus note on top of the lemon already whisked into the butter sauce.

Baking uncovered is specifically what allows the top of the fillets to dry very slightly while the submerged portion stays moist in the butter — this contrast, though subtle, is part of what gives the finished dish some textural interest beyond a uniformly soft result.
