Celebrating Simple, Sun-Drenched Ingredients

The magic of Mediterranean cooking is letting simple, high-quality ingredients shine. There are a few key players in this dish that make all the difference.

Whole Branzino

Don’t be intimidated! Branzino, also known as Mediterranean sea bass, is a wonderfully mild and slightly sweet white fish. Roasting it whole keeps the flesh incredibly moist and tender, and it’s a fantastic source of lean protein and those amazing omega-3 fatty acids.

High-Quality Extra Virgin Olive Oil

Olive oil is the liquid gold of the Mediterranean. For a recipe like this, where it’s a key part of the flavor, use a good quality extra virgin olive oil. Its fruity, peppery notes tie all the other ingredients together beautifully.

Fresh Fennel

If you’ve never tried roasted fennel, you are in for such a treat. Raw, it has a crisp, licorice-like flavor. But when you roast it, it becomes tender, mellow, and wonderfully sweet. It’s the perfect vegetable to pair with fish.

Your Questions About This Mediterranean Fish Recipe, Answered

When you’re starting out, it’s normal to have questions! I know I did. Here are a few common ones I get that will help you feel like a pro.

1.What is the healthiest fish to eat on the Mediterranean diet?

Great question! The focus is on fish rich in omega-3s. Branzino is an excellent choice, as are other fatty fish like salmon, sardines, mackerel, and tuna. The goal is to enjoy fish a couple of times a week, so pick the ones you love!

2.How do you cook a whole fish in the oven?

It’s so much easier than you think! The key is high heat and not overthinking it. The method in this recipe is my favorite: roasting it on a bed of vegetables protects the fish, infuses it with flavor, and cooks your side dish at the same time. This is the secret to a perfect baked white fish with vegetables and lemon.

3.What vegetables go well with fish in a Mediterranean style?

Oh, so many! This recipe uses a classic combination of fennel, cherry tomatoes, red onion, and artichoke hearts. Other fantastic options include zucchini, bell peppers, asparagus, and olives. Think colorful, fresh, and seasonal!

Okay, are you ready to make the most delicious fish dinner of your life? Here’s how you do it.

Ingredients

  • 2 whole branzino about 1 lb / 450g each, scaled and cleaned, head and tail on
  • 1 large fennel bulb trimmed, cored, and thinly sliced
  • 1 can 15-ounce / 425g chickpeas, rinsed and drained thoroughly
  • 1 large red onion cut into thin wedges
  • 1 cup about 150g quartered artichoke hearts (packed in water, not oil), drained
  • 1 cup about 150g cherry tomatoes
  • 4 cloves garlic thinly sliced
  • 1 lemon halved
  • ¼ cup 60 ml high-quality extra virgin olive oil, divided
  • ½ teaspoon fine sea salt
  • ½ teaspoon black pepper
  • 2 sprigs fresh oregano
  • A small bunch of fresh flat-leaf parsley for stuffing and garnish

Instructions

  • Preheat your oven to 425°F (220°C) with a rack in the center.
  • On a large, heavy-duty rimmed baking sheet, combine the sliced fennel, rinsed chickpeas, red onion wedges, artichoke hearts, cherry tomatoes, and sliced garlic. Drizzle with half of the extra virgin olive oil (2 tablespoons), the fine sea salt, and black pepper. Toss everything together until evenly coated, then spread into a single, even layer.
  • Thoroughly pat both branzino dry with paper towels, inside and out. Using a sharp knife, make 3 shallow diagonal scores on each side of the fish. Rub the remaining 2 tablespoons of olive oil all over the fish, ensuring it gets into the scores and the cavity. Place a few sprigs of parsley and one sprig of oregano inside the cavity of each fish.
  • Lay the conditioned branzino directly on top of the bed of vegetables on the baking sheet. Place the two lemon halves, cut-side down, on an open corner of the pan. Transfer the entire sheet to the preheated oven.
  • Roast for 18-20 minutes, or until the vegetables are tender and the fish is opaque and starting to flake.
  • Turn the oven to the high broil setting. Move the oven rack so the fish skin is about 6 inches from the heating element. Broil for 2-4 minutes, watching carefully, until the skin is beautifully blistered and crisp.
  • Carefully remove the baking sheet from the oven. Gently transfer the whole roasted fish to a large serving platter. With tongs, pick up the hot, charred lemon halves and squeeze their smoky, caramelized juice all over the vegetables remaining on the pan.
  • Toss the vegetables in the pan juices to create an instant, warm vinaigrette. Spoon this flavorful vegetable and chickpea mixture artfully around the fish on the platter. Garnish generously with fresh, chopped parsley and serve immediately.
