Halibut Romesco

Greenwich, Connecticut has long set the standard for refined living—and that expectation extends naturally to the table. As a personal chef serving Greenwich and all of Fairfield County, I bring the same rigor and artistry found in Michelin-starred kitchens directly into your home. The dish you are about to explore—Halibut Romesco—is among the most requested on my private dining menus, year after year, from intimate weeknight suppers in backcountry Greenwich to landmark holiday celebrations in the great estates along Round Hill Road.

Halibut Romesco bridges two worlds I love deeply: the clean, cold-water purity of Pacific halibut and the bold, sun-soaked complexity of Catalonia's most celebrated sauce. It is a dish that reads as effortlessly elegant at the table while quietly demanding real skill in the kitchen—exactly the kind of cooking I was trained to deliver over four decades in professional kitchens.

Romesco traces its roots to the fishing port of Tarragona on the southern coast of Catalonia, where fishermen needed a sauce rugged enough to stand up to the intense, smoky flavor of freshly caught salt cod and shellfish roasted over open fires on the beach. The word itself likely derives from the Catalan romesco, a wild red pepper variety native to the region that arrived in Spain via South America in the sixteenth century and quickly transformed Catalan cuisine forever.

By the eighteenth century, inland villages in the Camp de Tarragona region had codified Romesco into something approaching its modern form: dried ñora peppers or roasted red peppers blended with toasted almonds or hazelnuts, ripe tomatoes, fried bread for body, garlic, olive oil, and sherry vinegar for the necessary acid lift. Every family kept a slightly different version, some adding smoked paprika (pimentón de la Vera), some preferring hazelnuts over almonds, others adding a pinch of cayenne for heat. Romesco resisted standardization because it was never meant to be standardized—it was peasant ingenuity at its most inspired.

The sauce gained international recognition in the late twentieth century when Catalan cuisine emerged as one of the world's most innovative food cultures. Today, Romesco sits alongside aioli and sofregit as a foundational pillar of Catalan cooking, beloved in fine dining rooms from Barcelona to New York—and now, from my kitchen, to yours in Greenwich.

Exceptional ingredients are not optional—they are the foundation. When preparing Halibut Romesco for my Greenwich clients, I source with intention from the finest local purveyors Fairfield County has to offer.

For the halibut itself, I work exclusively with sustainable, day-boat Pacific halibut—thick, pristine fillets with a sweet, briny finish that hold up beautifully to the rich Romesco. Fresh thyme and flat-leaf parsley come from Gilbertie's Herb Farm in Westport, the oldest herb farm in the United States, where organically cultivated herbs are harvested at peak oil concentration. Roasted red peppers are made in-house from local greenhouse-grown peppers found at the Westport Farmers Market (open seasonally on Imperial Avenue) and the Greenwich Farmers Market at Horseneck Parking Lot—a beloved weekend ritual for my clients in the Cos Cob and Old Greenwich neighborhoods.

1. Roast the peppers. Place red peppers directly over an open flame or under a broiler, turning until completely charred on all sides, about 10–12 minutes. Transfer to a bowl, cover with plastic wrap, and rest 15 minutes. Peel, seed, and roughly chop.

2. Blister the tomatoes. Halve Roma tomatoes, drizzle with olive oil, season with salt, and roast cut-side up at 400°F for 20 minutes until softened and caramelized at the edges.

3. Toast the almonds. In a dry skillet over medium heat, toast almonds 4–5 minutes, tossing frequently, until fragrant and golden. Remove immediately to prevent burning.

4. Fry the bread. In 1 tbsp olive oil, fry the torn bread slice until deeply golden and crisp on all sides. Drain on paper towels.

5. Build the Romesco. Combine peppers, tomatoes, almonds, garlic, fried bread, sherry vinegar, and smoked paprika in a blender. Pulse to a rough paste. With the motor running, stream in ¼ cup olive oil until the sauce is emulsified but still has texture—not perfectly smooth. Season generously with salt. Taste for vinegar balance. Set aside; reheat gently before plating.

6. Season the halibut. Pat fillets completely dry. Season both sides with kosher salt 20 minutes before cooking to allow moisture to draw out and reabsorb. Pat dry again just before searing.

7. Sear to perfection. Heat a cast-iron skillet over high heat until smoking. Add 2 tbsp olive oil, swirl to coat. Lay halibut presentation-side down. Reduce heat to medium-high. Cook undisturbed for 3–4 minutes until a golden crust forms. Flip, add butter and thyme, and baste continuously for 2–3 minutes. Internal temperature should reach 130°F for a slightly translucent, silky center—the hallmark of properly cooked halibut.

8. Plate with intention. Spoon warm Romesco generously across the center of each warmed plate. Lay the seared halibut fillet directly over the sauce. Finish with a squeeze of fresh lemon, a drizzle of your best olive oil, picked flat-leaf parsley, and a lemon cheek on the side. Serve immediately.
