When I want a seafood dinner that’s both simple and full of fresh flavor, this Mediterranean Baked Haddock is one of my go-to recipes. Tender haddock fillets are baked with sweet tomatoes, briny olives, lemon, herbs, and creamy feta, creating an easy one-pan meal that’s light, colorful, and satisfying.
As the fish bakes, the tomatoes release their juices, blending with olive oil, lemon, and seasonings to create a flavorful Mediterranean-inspired sauce. The result is a dish that feels special enough for entertaining but is simple enough to make on a busy weeknight.
Author’s Note – The Simple Joy of Coastal Living
Last week, when I shared my Lemon Butter Pan-Seared Scallops recipe, I mentioned how fortunate we are to have a local fisherman friend who delivers fresh seafood from the Massachusetts coast to our door every week during the summer months. Haddock is one of the fish I receive most often, and this Mediterranean Baked Haddock has become one of my favorite ways to prepare it.
The combination of tomatoes, olives, lemon, olive oil, and feta allows the fresh fish to shine while creating a simple Mediterranean-inspired sauce that’s perfect for soaking up with a piece of crusty bread. It’s one of those recipes I find myself making on repeat all season long.
It’s delicious and I hope you’ll love it as much as we do!

What Makes This Recipe Mediterranean
Mediterranean cooking is often built around simple ingredients that don’t need much fuss. Olive oil, fresh fish, tomatoes, herbs, olives, lemon, and feta cheese are all staples throughout Mediterranean coastal regions.
Rather than relying on heavy sauces, this recipe lets fresh ingredients create their own flavor. As the tomatoes soften and release their juices, they combine with olive oil, lemon, and herbs to create a light sauce that perfectly complements the delicate haddock.
silvia’s tips for the best baked fish
➜ Use the freshest fish available. Living in New England, I’m fortunate to have access to excellent seafood, and this recipe really lets quality fish shine.
➜ Don’t skip the lemon slices. They gently perfume the fish as it bakes and help create the bright Mediterranean flavor profile.
➜ Use colorful cherry tomatoes if possible. The combination of red and yellow tomatoes adds beautiful color to the finished dish. I usually grow a variety of tomatoes in my garden, so that’s always a pleasant add-on
➜ Add the feta after baking. Keeping the feta fresh preserves its creamy texture and prevents it from drying out in the oven.
➜ Let the tomatoes do the work. During baking, the tomatoes release their juices and combine with the olive oil, lemon, and seasonings to create a simple but flavorful sauce.
➜ Avoid overcooking the fish. Haddock is done when it flakes easily with a fork and reaches 145°F in the thickest part.
