More about Joe →Flaky cod, caramelized fennel, bright tomatoes all done in one skillet and on the table fast. Mediterranean One Pan Cod Fennel is the kind of dish that looks like you tried way harder than you actually did.
Spring last year, I was shooting a whole series of lighter dinners and kept coming back to this one the golden sear on the cod, the way the fennel goes almost sweet and silky in the pan. It’s the kind of easy win that makes busy weeknights feel manageable again. After eight years behind the lens in test kitchens, I’ve learned that the secret is getting the skillet genuinely hot before the fish goes in that’s what gives you that beautiful crust instead of a soggy bottom.

Ingredients
Notes
- Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, cover the fish with foil and warm in the oven at 350°F until heated through, or gently warm individual servings in the microwave. Add a squeeze of fresh lemon juice before serving to brighten the flavors.
Why You’ll Love This One Pan Cod Fennel
Here’s why this one keeps coming back into the weeknight rotation it looks stunning on the table and takes almost no effort to pull together. The fennel turns soft and almost sweet in the oven, the cherry tomatoes burst into something jammy and rich, and the cod comes out tender and flaky every single time.
It’s the kind of dinner worth reaching for on tired spring evenings when you still want the meal to feel like something comforting but not heavy, easy but not boring.
What You’ll Need
No specialty shopping required. Every ingredient here does real work, and most of it is already in a well-stocked kitchen.
- Cod fillets mild, flaky, and quick-cooking; halibut or sea bass work just as well
- Fennel bulb thinly sliced so it softens fully; sub a large shallot or half a yellow onion if needed
- Cherry tomatoes halved so they break down into a light, saucy base
- Capers small but mighty; they add a briny punch that balances the sweetness
- Extra-virgin olive oil, red wine vinegar, and honey this trio creates the flavor backbone of the whole dish
- Lemon slices and fresh basil don’t skip the garnish; it lifts everything at the end
How to Make It
The process is straightforward: roast the vegetable base first, then nestle in the fish. That two-stage approach is what keeps the cod from overcooking while the fennel gets properly golden.
- Preheat your oven to 400°F.
- Slice the fennel bulb thinly after removing the stalks, root end, and core from each quarter.
- In a 4-quart baking dish, combine cherry tomatoes, fennel, garlic, capers, 3 tablespoons olive oil, red wine vinegar, honey, half the salt, and chili flakes if using. Stir well.
- Bake uncovered for 20 to 25 minutes, until the tomatoes are broken down and jammy.
- Pat cod fillets dry, brush with remaining olive oil, and season with the remaining salt and black pepper.
- Toss the tomato mixture, nestle the fish into the pan, and top each fillet with a lemon slice. Roast 10 to 15 minutes until the fish flakes easily.
- Finish with chopped fresh basil and spoon the tomato mixture over each fillet when serving.
Pro Tip: Patting the fish completely dry before brushing with oil makes a noticeable difference in how cleanly the fillets hold together in the pan.
Can You Make This Mediterranean One Pan Cod Fennel Ahead of Time?
The tomato and fennel base is the part that benefits most from advance prep. You can roast that mixture up to a day ahead and refrigerate it in the baking dish. When you’re ready to eat, bring it back to temperature in the oven, then add the fish and finish roasting fresh cod is always best cooked right before serving.
Storage and Reheating Tips
Leftovers store well for up to two days, though the fish is at its best the day it’s made.
- Refrigerate in an airtight container for up to 2 days
- To reheat without drying out the cod, cover the baking dish with foil and warm at 350°F until heated through
- A small squeeze of lemon juice before serving wakes up the flavors after reheating
- Individual portions can also be reheated gently in the microwave on a low setting
Simple Swaps Worth Knowing
The recipe is flexible without losing any of what makes it work.
- Swap cod for halibut or sea bass both hold up beautifully in this style of roasting
- No fennel bulb? Use one large shallot or half a yellow onion for a milder base
- Red chili flakes are optional leave them out for a gentler, kid-friendly version
- Fresh basil is worth seeking out here, but flat-leaf parsley is a decent backup

Can I substitute another fish for cod in this recipe?
Yes – halibut or sea bass work well as direct swaps. Keep the same fillet size and check for doneness around the same roasting time.
How long to bake Mediterranean cod in one pan?
The tomato and fennel base roasts for 20 to 25 minutes at 400 degrees F, then the cod fillets go in for 10 to 15 minutes until they flake easily with a fork.
What vegetables go with Mediterranean baked cod?
This dish already features cherry tomatoes and fennel as built-in vegetables. If fennel is unavailable, the recipe suggests subbing a large shallot or half a yellow onion.
