Instructions

Prepare the Oven and Vegetables

Preheat the oven to 400°F (200°C). Lightly grease a large baking dish with olive oil.

Add the sliced carrots, zucchini, yellow bell pepper, and onion or leek to the baking dish. Drizzle with olive oil and season with a little salt, black pepper, and half of the dried thyme or oregano.

Toss the vegetables gently so they are evenly coated. Spread them into an even layer.

Make the Creamy Sauce

In a bowl, whisk together the heavy cream, minced garlic, white wine or vegetable broth, lemon juice, and the remaining dried thyme or oregano. Add a little salt and freshly cracked black pepper.

Stir in the chopped fresh dill, reserving a few sprigs for garnish.

The sauce should be smooth and lightly seasoned. The lemon will brighten the cream while the garlic and herbs add Mediterranean flavor.

Partially Roast the Vegetables

Place the vegetable-filled baking dish in the preheated oven and roast for about 12–15 minutes.

This gives the firmer vegetables, especially the carrots, a head start before the cod is added. The vegetables should begin to soften but should not be completely cooked.

Add the Cod and Sauce

Remove the baking dish from the oven and carefully arrange the cod fillets over the vegetables.

Season each cod fillet with salt and black pepper. Pour the creamy herb sauce around and slightly over the fish, allowing some of it to settle among the vegetables.

Drizzle the tops of the cod fillets lightly with olive oil and add a few fresh dill sprigs.

Bake Until Flaky

Return the dish to the oven and bake for approximately 15–18 minutes, depending on the thickness of the cod.

The fish is ready when it becomes opaque, flakes easily with a fork, and reaches an internal temperature of 145°F (63°C).

Avoid overbaking because cod can become dry when cooked for too long.

Finish and Serve

Remove the dish from the oven and let it rest for a few minutes. Spoon some of the creamy sauce and roasted vegetables over each cod fillet.

Finish with fresh dill and a squeeze of lemon juice. Serve immediately with your favorite side dish.

Tips

Choose Thick Cod Fillets

Thick, firm cod fillets work especially well because they remain juicy while the vegetables finish roasting. If using thinner fillets, reduce the final baking time and check them earlier.

Cut Vegetables Evenly

Try to keep the carrot, zucchini, pepper, and onion pieces relatively similar in size. This helps them cook more evenly and prevents some vegetables from becoming too soft while others remain firm.

Give Carrots a Head Start

Carrots take longer to become tender than zucchini and bell pepper. Pre-roasting the vegetables before adding the cod helps create a better final texture.

Do Not Overcrowd the Dish

Arrange the vegetables in a fairly even layer and leave enough space for the cod fillets. Overcrowding can cause the vegetables to steam instead of roast.

Use Fresh Lemon

Fresh lemon juice provides a brighter flavor than bottled lemon juice and balances the richness of the creamy sauce beautifully.

Check the Fish Early

Cod thickness can vary significantly. Begin checking the fish around the 15-minute mark to prevent overcooking.

Let the Dish Rest Briefly

Allowing the baked cod to rest for a few minutes after removing it from the oven gives the sauce a chance to settle and makes serving easier.

Variations

Use Greek Yogurt

For a lighter creamy sauce, replace the heavy cream with plain Greek yogurt. To prevent curdling, whisk the yogurt with the broth and add it carefully rather than exposing it to very high heat for an extended time.

Try Another White Fish

Cod can be replaced with haddock, halibut, or sea bass. Adjust the cooking time according to the thickness of the fish.

Add Mediterranean Olives

For an extra Mediterranean touch, add a small handful of sliced Kalamata olives to the vegetables before baking.

Add Cherry Tomatoes

Halved cherry tomatoes can be added to the vegetable mixture. They become juicy and slightly caramelized as they roast and add extra freshness to the creamy sauce.

Add Spinach

A handful of fresh baby spinach can be stirred into the warm sauce near the end of cooking. The residual heat will soften the leaves without making them overly wilted.

Make It Dairy-Free

Use a dairy-free cream alternative or a smooth unsweetened plant-based cream. Keep the rest of the ingredients the same for a dairy-free variation.

Q&A

Can I use frozen cod?

Yes. Thaw the cod completely in the refrigerator and pat it very dry with paper towels before cooking. Excess moisture can make the dish watery.

What fish can I use instead of cod?

Haddock, halibut, and sea bass are good alternatives. Since different fish vary in thickness and moisture, cooking time may need to be adjusted.

Can I make this recipe without wine?

Yes. Replace the dry white wine with vegetable broth. The broth will still provide moisture and flavor for the creamy sauce.

How do I know when cod is done?

The fish should be opaque throughout and flake easily with a fork. For food safety, the thickest part should reach 145°F (63°C).

Can I prepare the vegetables ahead of time?

Yes. The vegetables can be sliced several hours ahead and refrigerated in an airtight container. Prepare the sauce separately and assemble the dish shortly before baking.

What should I serve with creamy baked cod?

This dish pairs well with crusty bread, rice, couscous, quinoa, roasted potatoes, or a simple green salad.
