Smoky One-Pan Roasted Branzino with Fennel
This roasted branzino with fennel sits on a bed of chickpeas that get crispy-edged and caramelized in the hot oven. It looks like a complex weekend project, but the whole meal comes together on a single sheet pan in under 40 minutes.
What Sets This Sheet Pan Seafood Apart
I track what foods actually keep me full, and standard white fish usually leaves me hungry an hour later. The fiber-heavy base of chickpeas and artichokes completely changes that equation.
Broiling the whole fish at the very end blisters the skin without drying out the delicate meat underneath. Squeezing the charred, hot lemon over the pan creates an instant warm vinaigrette that mixes perfectly with the olive oil and roasting juices.

Building the Roasted Branzino with Fennel
Start by tossing the fennel, chickpeas, artichokes, and tomatoes directly on your sheet pan. Spread them into a single layer so they roast instead of steaming. If the pan is crowded, the vegetables will turn mushy.
Score the branzino three times on each side. I usually rub the olive oil deep into these cuts to make sure the meat actually absorbs the flavor. Stuff the cavity with parsley and oregano.
Lay the fish right on top of the vegetables. Add the lemon halves face-down, then roast at 425°F for 18-20 minutes.
Flip the oven to broil for the last few minutes. You want the skin blistered and the thickest part of the fish to hit 145°F. Once it is out of the oven, squeeze those caramelized lemons over the vegetables and toss them in the hot pan juices.
A Few Quick Notes Before You Roast
- The most common mistake: Not patting the fish entirely dry before scoring. Moisture is the enemy of crispy skin.
- Dietary swaps: If you do not love fennel, swap it for thinly sliced bell peppers. It still hits that classic Mediterranean branzino recipe flavor profile.
- Serving contrast: Serve it alongside an arugula salad if you want a sharp, peppery bite to cut through the rich olive oil. Alternatively, a side of creamy tzatziki works well for dipping the fish.
- Storage: The fish is best eaten immediately, but the roasted chickpeas and vegetables keep in the fridge for up to 3 days.

Description
A stunning, heart-healthy centerpiece that captures the essence of coastal Mediterranean cooking. This one-pan recipe features a whole, tender branzino roasted to perfection atop a rustic bed of sweet fennel, creamy chickpeas, and artichoke hearts. The secret is the instant vinaigrette, created by squeezing fire-charred lemon over the hot pan, mingling its smoky juice with olive oil and fresh herbs for an unforgettable finish.
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; confirm the thickest part of the fish reaches 145°F (63°C) or flakes easily with a fork.
- 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.

Final Thoughts
I often pair this with a high-fiber socca to soak up the leftover lemon vinaigrette from the pan. I feel full for hours after eating this, without that heavy, sluggish feeling that usually follows a big dinner.
