Ingredients You’ll Need

Branzino and Marinade

• 2 whole branzino, cleaned and scaled, about 1 to 1¼ pounds each
  • Ask the fish counter to gut and scale them to save time.
• 3 tablespoons extra virgin olive oil
• 3 cloves garlic, finely minced or pressed
• Zest of 1 lemon
• Juice of 1 lemon (about 3 tablespoons)
• 1 teaspoon kosher salt
• ½ teaspoon freshly ground black pepper
• 1 teaspoon dried oregano or Italian seasoning
• ½ teaspoon smoked paprika or sweet paprika
• 1 tablespoon fresh parsley, finely chopped
• 1 tablespoon fresh dill or basil, finely chopped
• 1 extra lemon, sliced into thin rounds for stuffing and topping

Potatoes and Veggies

• 1½ pounds baby potatoes or Yukon Gold potatoes, thinly sliced
  • Use baby potatoes if you want less peeling and quicker prep.
• 1 red bell pepper, sliced into strips
• 1 yellow bell pepper, sliced into strips
• 1 small red onion, sliced into wedges
• 1 small zucchini, sliced into half moons
• 10 to 12 cherry tomatoes, left whole
• 2 to 3 tablespoons extra virgin olive oil
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• 1 teaspoon dried oregano
• ½ teaspoon garlic powder
• Optional: ¼ teaspoon crushed red pepper flakes for a little heat

Pantry Shortcuts and Substitutions

• Use bottled lemon juice if you must, but fresh lemon gives brighter flavor.
• Swap branzino with whole snapper, trout, or sea bass if your store does not carry branzino.
• Replace fresh herbs with 1 extra teaspoon dried herbs if needed.
• Use frozen veggie mix (thawed and patted dry) if you want to cut chopping time.

Equipment List

• Large sheet pan or roasting pan
• Parchment paper or light oil for the pan
• Sharp knife and cutting board
• Small bowl for marinade
• Tongs or spatula
• Instant read thermometer (helpful but optional)
• Aluminum foil to tent the fish if it browns too fast

Tips & Tricks

• Pat the branzino very dry with paper towels so the skin crisps nicely.
• Slice the potatoes thinly and evenly so they cook through by the time the fish finishes.
• Toss the potatoes and veggies with oil and seasoning directly on the sheet pan to skip an extra bowl.
• Score the branzino skin with shallow diagonal cuts so the marinade sinks into the flesh.
• Stuff the cavity with lemon slices and herbs to keep the fish moist and fragrant.
• Roast the potatoes and veggies alone for 10 to 15 minutes before you add the fish so they soften and caramelize.
• Keep the fish in a single layer and avoid crowding the pan so the heat circulates well.
• Check the fish early at around 18 minutes so you do not overcook it.
• Use an instant read thermometer and pull the branzino when it reaches about 135 to 140°F in the thickest part.
• Squeeze fresh lemon over everything right before serving to brighten the flavors.

How to Make Oven Baked Mediterranean Branzino with potatoes and veggies

Prep the Oven and Pan

1. Heat the oven to 400°F and line a large sheet pan with parchment or lightly oil it.
2. Place the pan on the middle rack so the fish cooks evenly and the veggies caramelize.
3. Keep the branzino in the fridge while you prep the veggies so it stays cold and fresh.

Season the Potatoes and Veggies

1. Spread the sliced potatoes, bell peppers, red onion, zucchini, and cherry tomatoes on the sheet pan.
2. Drizzle with 2 to 3 tablespoons olive oil, then sprinkle with salt, pepper, dried oregano, garlic powder, and crushed red pepper flakes if you use them.
3. Toss everything with your hands until the veggies and potatoes coat evenly, then spread them into a single layer.

Par Roast the Veggies

1. Slide the pan into the oven and roast the potatoes and veggies for 10 to 15 minutes.
2. Stir once halfway through so the edges do not burn and the potatoes cook evenly.
3. Use this time to season the branzino so you keep the recipe moving.

Mix the Marinade

1. In a small bowl, combine olive oil, minced garlic, lemon zest, lemon juice, salt, pepper, dried oregano, smoked paprika, parsley, and dill.
2. Whisk until the mixture looks slightly thick and emulsified.
3. Taste a tiny bit and adjust salt or lemon to your liking.

Prep and Season the Branzino

1. Rinse the branzino under cold water and pat very dry inside and out.
2. Use a sharp knife to score the skin with 3 to 4 shallow diagonal cuts on each side.
3. Spoon some marinade inside the cavity and rub the rest all over the outside of the fish, including into the cuts.
4. Stuff the cavity with a few lemon slices and extra herb sprigs if you have them.

Add the Fish to the Pan

1. Pull the sheet pan from the oven after the veggies roast for 10 to 15 minutes.
2. Push the potatoes and veggies toward the edges to make space in the center.
3. Lay the branzino in the middle of the pan, then tuck a few lemon slices on top of the fish and around the veggies.
4. Spoon any remaining marinade over the fish and a little over the potatoes.

Roast the Branzino

1. Return the pan to the oven and roast for 18 to 22 minutes, depending on the size of your branzino.
2. Check at 18 minutes by inserting a fork into the thickest part of the flesh; it should flake easily and look opaque.
3. If the skin browns too quickly, tent the fish loosely with foil and finish roasting.
4. Pull the pan from the oven when the internal temperature reaches about 135 to 140°F and the veggies look tender and golden at the edges.

Finish and Serve

1. Let the branzino rest on the pan for 3 to 5 minutes so the juices settle.
2. Squeeze fresh lemon over the fish, potatoes, and veggies, then sprinkle with extra chopped parsley or dill.
3. Serve the whole branzino on the pan or transfer carefully to a platter with the roasted potatoes and veggies around it.
4. Offer extra lemon wedges at the table so everyone can adjust brightness to taste.

What to Serve with Oven Baked Mediterranean Branzino with potatoes and veggies

This Oven Baked Mediterranean Branzino with potatoes and veggies already gives you protein, carbs, and veggies, so you only need light sides. A simple cucumber and tomato salad with olive oil and herbs pairs nicely and keeps the meal fresh. You can also add warm pita bread or crusty bread to soak up the lemony pan juices. Serve with sparkling water, citrus infused water, or a light herbal iced tea to keep the Mediterranean vibe going.

Storage Options

• Store leftover branzino, potatoes, and veggies in an airtight container in the fridge for up to 2 days.
• Reheat gently in a 300°F oven for 10 to 12 minutes until warm so the fish stays moist.
• Avoid the microwave if possible since it can turn the fish rubbery, but use low power and short bursts if you must.
• Do not freeze the cooked branzino with veggies, since the texture of both fish and potatoes turns mushy after thawing.
