Mediterranean-Style Baked Cod with Vegetables & Creamy Sauce

by

This Mediterranean-style baked cod is the perfect balance of light and indulgent. Tender, flaky cod fillets are gently baked over colorful vegetables and finished in a rich yet bright creamy sauce infused with garlic, herbs, and a hint of citrus. It looks impressive enough for guests but is simple enough for a weeknight dinner.

The beauty of this dish lies in contrast: delicate white fish, roasted vegetables with slight caramelization, and a silky sauce that ties everything together. It’s wholesome, vibrant, and deeply satisfying without being heavy.

Below is the full detailed recipe with step-by-step instructions, tips, variations, storage guidance, and serving suggestions.

Ingredients (Serves 4)

For the Cod & Vegetables:

  • 4 cod fillets (6 oz each), skinless

  • 2 tablespoons extra virgin olive oil

  • 1 zucchini, sliced into half-moons

  • 1 red bell pepper, sliced

  • 1 yellow bell pepper, sliced (optional for color)

  • 1 cup cherry tomatoes, halved

  • 1 small red onion, thinly sliced

  • 2 medium carrots, sliced into rounds

  • 3 cloves garlic, minced

  • 1 teaspoon dried oregano

  • 1 teaspoon dried thyme

  • ½ teaspoon paprika

  • Salt and freshly ground black pepper, to taste

  • Juice of ½ lemon

For the Creamy Mediterranean Sauce:

  • 1 tablespoon olive oil or butter

  • 2 cloves garlic, finely minced

  • ½ cup vegetable or chicken broth

  • ¾ cup heavy cream (or half-and-half for lighter option)

  • ¼ cup grated Parmesan cheese

  • 1 teaspoon Dijon mustard

  • 1 tablespoon fresh lemon juice

  • 1 tablespoon chopped fresh dill (plus extra for garnish)

  • 1 tablespoon chopped fresh parsley

  • Salt and pepper to taste

Equipment Needed

  • Large oven-safe baking dish or casserole pan

  • Medium saucepan

  • Cutting board

  • Sharp knife

  • Mixing bowl

  • Whisk

  • Aluminum foil (optional)

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This temperature allows the vegetables to soften and caramelize while keeping the fish tender and moist.

Lightly grease your baking dish with olive oil to prevent sticking.

Step 2: Prepare the Vegetables

Slice all vegetables uniformly so they cook evenly. Try to keep pieces roughly the same thickness.

In a large mixing bowl, combine:

  • Zucchini

  • Bell peppers

  • Cherry tomatoes

  • Red onion

  • Carrots

  • Minced garlic

Drizzle with 2 tablespoons olive oil and season with:

  • Oregano

  • Thyme

  • Paprika

  • Salt

  • Black pepper

Toss thoroughly until everything is evenly coated.

Spread the vegetables in an even layer across the bottom of the baking dish.

Step 3: Pre-Roast the Vegetables

Place the dish in the oven and roast for 10–12 minutes before adding the fish. This gives the firmer vegetables (like carrots) a head start.

You’ll notice the vegetables beginning to soften and release their juices.

Step 4: Prepare the Cod

While the vegetables are roasting:

  • Pat the cod fillets dry with paper towels. This helps them brown slightly instead of steaming.

  • Lightly season both sides with salt, pepper, and a small squeeze of lemon juice.

  • Drizzle very lightly with olive oil.

Avoid over-seasoning — the sauce will add plenty of flavor.

Step 5: Add Cod to the Dish

Remove the vegetables from the oven.

Nestle the cod fillets gently on top of the vegetables. Spoon a little of the vegetable juices over each fillet for added moisture.

Return the dish to the oven and bake for 12–15 minutes, depending on thickness.

The fish is done when:

  • It flakes easily with a fork

  • It reaches an internal temperature of 145°F (63°C)

  • It appears opaque throughout

Be careful not to overcook — cod becomes dry quickly.

Preparing the Creamy Mediterranean Sauce

While the fish is baking, prepare the sauce.

Step 6: Sauté the Garlic

In a medium saucepan over medium heat:

  • Add 1 tablespoon olive oil or butter.

  • Add minced garlic and sauté for about 30 seconds until fragrant (do not brown).

Step 7: Build the Sauce Base

Pour in the broth and let it simmer for 2–3 minutes to reduce slightly.

Lower the heat and whisk in the heavy cream.

Let it simmer gently for 3–5 minutes until slightly thickened.

Step 8: Add Flavor Elements

Stir in:

  • Parmesan cheese

  • Dijon mustard

  • Lemon juice

  • Fresh dill

  • Fresh parsley

Whisk until smooth.

Taste and adjust salt and pepper as needed.

If the sauce becomes too thick, add a tablespoon of broth.
If too thin, simmer a bit longer.

Step 9: Combine and Finish

Once the cod is fully cooked:

  • Remove the baking dish from the oven.

  • Spoon the creamy sauce generously over the fish and vegetables.

  • Garnish with extra fresh dill and parsley.

Serve immediately while warm.

Why This Recipe Works

  1. Pre-roasting vegetables prevents sogginess.

  2. Cod bakes gently on top, absorbing flavor from below.

  3. Cream sauce adds richness without overpowering.

  4. Lemon balances the cream beautifully.

  5. Fresh herbs brighten everything.

It’s comfort food with Mediterranean freshness.

Serving Suggestions

This dish pairs beautifully with:

  • Warm crusty bread

  • Steamed rice

  • Couscous

  • Orzo pasta

  • Mashed potatoes

  • Quinoa

For a lighter option, serve it as-is in bowls with extra vegetables.

A crisp green salad with lemon vinaigrette complements it perfectly.
