Instructions

Prepare the oven and potatoes
Preheat oven to 200°C (400°F). Line a large baking tray with parchment paper. Toss baby potatoes with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Spread on half of the tray. Roast for 10 minutes.
Make the garlic herb butter
Meanwhile, in a small bowl, mix softened butter with garlic, parsley, dill, chives, lemon juice, and 1/4 teaspoon salt to make the garlic herb butter.
Prepare the cod
Pat cod fillets dry. Rub with 2 tablespoons olive oil, lemon zest, 1/2 teaspoon salt, and 1/4 teaspoon pepper.
Add green beans
After potatoes have roasted for 10 minutes, add green beans to the tray. Drizzle with a little olive oil and season with salt and pepper. Toss gently.
Add fish and finish baking
Place cod fillets on the tray. Top each fillet with a generous dollop of garlic herb butter. Return tray to oven and bake for 12–15 minutes, until cod is just opaque and flakes easily, potatoes are golden, and green beans are crisp-tender.
Serve
Serve immediately, spooning any melted herb butter from the tray over the cod and vegetables.

Zusatztipps für die Zubereitung

The key to perfect cod is avoiding overcooking. The fish should be just opaque and flake easily when tested with a fork. If your fillets are thicker or thinner than 150g each, adjust the cooking time accordingly. For thinner fillets, you may want to add them to the tray a few minutes after adding the green beans.

Varianten und Anpassungen

This recipe works beautifully with other firm white fish like haddock or pollock. For a heartier version, add sliced lemon under the fish before baking. If you enjoy a bit of heat, sprinkle red pepper flakes over the top before serving. You can also swap the herb mixture based on what's available - thyme and rosemary make excellent alternatives to dill.

Serviervorschläge

Serve this dish straight from the oven with the melted herb butter spooned generously over the top. A crisp Sauvignon Blanc or Pinot Grigio makes an excellent pairing, highlighting the delicate flavors of the fish. For a complete meal, all you need is a slice of crusty bread to soak up the incredible sauce.
