The CityLife Pergola: Crisp Pan-Roasted Branzino with Crushed Fingerlings and Castelvetrano-Vermouth Butter

Instructions

1. 1

   Place 1 lb baby fingerling potatoes in a medium saucepan, cover with cold water by an inch, add 0.5 tsp flaky sea salt, and bring to a lively boil over medium-high heat. Simmer until completely tender when pierced with a paring knife, about 12 minutes.

   14 min

   Tip: Starting potatoes in cold water ensures they cook evenly from core to skin without bursting.

2. 2

   While the potatoes simmer, prep the fish's building envelope: score the skin of the 4 skin-on branzino fillets with 3 shallow diagonal slashes. Blot both sides vigorously with paper towels until bone-dry, then season both sides evenly with 0.25 tsp flaky sea salt and 0.25 tsp freshly cracked black pepper.

   5 min

   Tip: Scoring prevents the fillets from curling upwards in the skillet, guaranteeing flush contact and crackling skin.

3. 3

   Drain the cooked 1 lb baby fingerling potatoes and return them to the warm pot. Use a fork or potato masher to crush them gently into rustic chunks, then fold in 1 tbsp extra-virgin olive oil, 1 tbsp unsalted butter, a pinch of the remaining 0.25 tsp flaky sea salt, and 0.25 tsp freshly cracked black pepper. Cover with a lid to keep warm.

   3 min

   Tip: These crushed potatoes act as the load-bearing base of your plate, catching every bead of pan sauce.

4. 4

   Set a large 12-inch stainless steel or cast-iron skillet over medium-high heat and warm 2 tbsp extra-virgin olive oil until shimmering. Lay the seasoned 4 skin-on branzino fillets skin-side down, pressing firmly with a flexible fish spatula for the first 30 seconds to anchor the skin flush against the hot metal. Pan-roast undisturbed until the skin is deeply golden and crisp, about 4 minutes.

   5 min

   Tip: Do not move the fillets prematurely; the fish will naturally release from the pan once the skin caramelizes.

5. 5

   Gently flip the 4 skin-on branzino fillets onto their flesh side and cook for just 1 minute more until opaque and barely cooked through. Transfer immediately to a warm platter, skin-side up, to preserve that fragile crunch.

   1 min

   Tip: The residual heat will finish carrying the delicate white flesh to a silky, melting flake.

6. 6

   Pour off any excess surface oil, return the skillet to medium heat, and add 1 medium shallot and 8 fresh sage leaves. Sauté for 1 minute until the shallot softens and the sage leaves turn fragrant and crisp. Pour in 0.33 cup dry vermouth and 0.33 cup rich vegetable or chicken brodo, scraping up the caramelized pan drippings, and reduce by half, about 2 minutes.

   3 min

   Tip: Dry vermouth delivers botanic complexity instantly, eliminating the need for prolonged sauce reductions.

7. 7

   Lower the heat to low. Stir in 0.5 cup Castelvetrano olives and vigorously swirl in the remaining 3 tbsp unsalted butter one cold cube at a time until the sauce transforms into a glossy, velvety emulsion. Remove from heat, stir in 1 tbsp fresh lemon juice, and taste for balance, seasoning with any remaining 0.25 tsp flaky sea salt if desired.

   2 min

   Tip: Cold butter is essential here for emulsification—stir continuously off direct heat to avoid breaking the sauce.

8. 8

   Spoon a generous mound of the warm crushed potatoes onto each of four shallow plates. Rest a crisp 4 skin-on branzino fillets fillet proudly over the potatoes, then spoon the buttery Castelvetrano olive and vermouth reduction alongside, garnishing with the crisped 8 fresh sage leaves.

   2 min

   Tip: Spoon the sauce around the base rather than over the fish to keep that architectural skin singing with crunch.
