Oven Baked Mediterranean Branzino with potatoes and veggies tastes bright, lemony, and savory, with tender fish, crisp-edged potatoes, and juicy, olive-studded veggies. It suits weeknight cooks and dinner hosts who want a 40-minute sheet pan dinner with big flavor and minimal fuss. I grew up sneaking extra roasted potatoes off the pan, and I still do.
Easy Oven Baked Mediterranean Branzino with potatoes and veggies
Oven Baked Mediterranean Branzino with potatoes and veggies uses one sheet pan, simple pantry staples, and a hot oven that does the heavy lifting. You toss the veggies, season the fish, and roast. The skin turns crisp, the flesh stays moist, and cleanup stays painless.
You can find whole branzino at most fish counters, and the fishmonger will clean and scale it for you on request. Pre-cut potatoes and cherry tomatoes shorten prep, and a quick herb-lemon oil ties everything together. You get restaurant-level results without fancy gear.
Ingredients You Need
- 2 whole branzino, 1 to 1.25 pounds each, cleaned and scaled
- Sub: whole dorade, trout, or small snapper; for fillets, use 4 skin-on fillets and reduce cook time
- 1 pound baby Yukon gold potatoes, thinly sliced into 1/4-inch rounds
- Shortcut: use pre-washed mini potatoes; you can also cube Yukon golds
- 1 red onion, cut into thick wedges
- 1 red bell pepper, sliced
- 1 cup cherry tomatoes
- 1/2 cup pitted Kalamata olives
- 2 tablespoons capers, drained
- 1 large lemon, zested and cut into rounds
- 4 cloves garlic, minced or grated
- 1/4 cup extra-virgin olive oil
- I like California or Greek EVOO for peppery flavor
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme or 1 tablespoon chopped fresh
- 1/2 teaspoon sweet paprika
- Pinch red pepper flakes, optional
- 1/3 cup dry white wine or low-sodium chicken broth
- 1/2 cup chopped fresh parsley
- Kosher salt and freshly ground black pepper
Equipment
- Large rimmed sheet pan, 18×13 inches
- Parchment paper
- Paper towels
- Sharp knife and cutting board
- Microplane or fine grater for lemon and garlic
- Instant-read thermometer
- Fish spatula or thin metal spatula
How to Make Oven Baked Mediterranean Branzino with potatoes
- Prep: 15 minutes
- Cook: 25 minutes
- Total: 40 minutes
- Heat the oven to 425°F. Line the sheet pan with parchment. Pat the fish dry inside and out.
- Mix the flavor base: in a bowl, combine olive oil, garlic, lemon zest, oregano, thyme, paprika, red pepper flakes, 1 teaspoon salt, and 1/2 teaspoon black pepper.
- Toss the potatoes, onion, bell pepper, cherry tomatoes, olives, and capers with half of the oil mixture. Spread the veggies in a single layer on the pan and tuck in half the lemon rounds.
- Roast the veggies for 12 minutes to jump-start browning.
- Prep the branzino while the veggies roast. Score each side of the fish with 3 shallow diagonal slashes. Season the cavity and skin with salt and pepper, then stuff the cavity with remaining lemon rounds and a little parsley.
- Pull out the pan. Push the veggies to the edges and place the fish in the center. Spoon the remaining oil mixture over the fish and splash the wine around the veggies.
- Return the pan to the oven and roast 12 to 15 minutes, depending on fish size. Check the thickest part with a thermometer; it should read 135°F and the flesh should flake easily.
- For extra-crisp skin, switch to broil for 1 to 2 minutes while you watch closely. Pull the pan, rest the fish 5 minutes, then shower with chopped parsley and a squeeze of lemon juice.
Tips & Common Mistakes
- Dry the fish well so the skin crisps.
- Score lightly; deep cuts can dry the flesh.
- Slice potatoes thin and evenly for tender centers and crisp edges.
- Give veggies a head start so the fish does not overcook.
- Do not crowd the pan; use two pans if needed for good browning.
- Season the cavity and the skin for full flavor.
- Use an instant-read thermometer; pull at 135°F for moist fish.
- If you use fillets, roast veggies 15 minutes, then add fillets skin-side up and cook 8 to 10 minutes.
- Keep lemon zest in the oil mix and lemon slices in the cavity; that combo brings bright flavor without bitterness.
- Skip the wine if you prefer; use broth or water and a splash of extra lemon juice.
Variations I’ve Tried
- Greek-style: add more oregano, sprinkle crumbled feta over the veggies for the last 5 minutes, and finish with dill.
- Chermoula vibe: swap the dried herbs for a paste of cilantro, parsley, garlic, cumin, coriander, paprika, lemon, and olive oil.
- Fennel-forward: add 1 bulb thin-sliced fennel to the veggies and use orange zest in place of lemon zest.
- Herb and citrus mix: tuck orange and lemon slices in the cavity and finish with basil and mint.
- Spicy: rub the fish with a little harissa mixed into the oil and use extra red pepper flakes.
- Olive lovers: add green Castelvetrano olives for buttery pop and double the capers.
How to Serve Oven Baked Mediterranean Branzino
Set the fish on the veggies and spoon the pan juices over everything. Add a drizzle of good olive oil, extra lemon, and more parsley for color. Pair with a crisp salad, warm crusty bread, or couscous to catch the juices. Chill a bottle of Sauvignon Blanc or Assyrtiko, or pour sparkling water with lemon if you keep it zero-proof.
Storage
- Make-ahead: slice the veggies, mix the oil seasoning, and store both in the fridge up to 24 hours. Ask the fish counter to clean and scale the branzino so you can go straight to roasting. Pat the fish dry right before cooking.
- Storage: store leftovers in a shallow container up to 2 days in the fridge. The skin softens, but the flavors stay great.
- Reheat: warm the fish and veggies on a sheet pan at 300°F for 10 to 12 minutes, loosely covered with foil. For a little skin snap, uncover and broil 1 minute at the end while you watch closely.
- Freezer: you can freeze cooked fish up to 2 months, though texture drops. Thaw overnight in the fridge, then reheat gently.
