Place & Heritage

Greenwich & Fairfield County — Where American Affluence Meets a Discerning Table

Long before the hedge funds arrived, Greenwich was already something special. Settled in 1640, it drew merchants, artists, and generations of families who understood that how you live matters — and that a beautiful setting deserves a beautiful table. Perched at the southwestern edge of Connecticut, where the Mianus River meets the Long Island Sound, Greenwich became the anchor of Fairfield County: a corridor of graceful estates, stone walls, and understated wealth stretching north through Westport, Darien, and New Canaan to Ridgefield.

Fairfield County developed a culinary identity to match its ambitions — one rooted in fresh local produce from the shores and farms of the Connecticut River Valley, refined through decades of proximity to New York's finest restaurants and food suppliers. Greenwich residents have always eaten well: farmers markets that draw serious cooks, specialty butchers, and a quiet preference for ingredients that don't need an explanation. There is no pretension here, only expectation — an expectation that whatever arrives at the table has been thoughtfully sourced, skillfully prepared, and served with the kind of warmth that makes guests linger well past dessert. That standard is exactly where Private Chef Robert feels most at home.

Why Private Chef Robert

What Are the Benefits of Hiring a Private Chef in Greenwich, CT?

The single greatest benefit of hiring a private chef in Greenwich is also the simplest: your home becomes a five-star dining experience — one that has been designed entirely around you, your guests, and the occasion at hand. Not a restaurant's version of five-star. Not a caterer's interpretation of your preferences. Yours, completely.

For a Greenwich homeowner, that distinction matters more than it might anywhere else. You entertain discerning guests. Your dinner table has hosted people who have dined at Eleven Madison Park, vacationed in Tuscany, and know the difference between Pecorino Romano and Pecorino Toscano. You are not looking for competent. You are looking for exceptional — and for the rare combination of excellence and ease, where the evening simply unfolds without friction, without logistical anxiety, and without you spending your own dinner party in the kitchen.

Private Chef Robert builds every menu from the ground up, in direct conversation with you. There are no printed options to choose from, no tier packages to select. You discuss the occasion — whether it's an intimate dinner for eight, a Marche-inspired regional tasting for twelve, or a relaxed Sunday supper for the family — and Chef Robert designs accordingly. Dietary restrictions, personal preferences, the season, the rhythm of the evening: all of it factors in before a single ingredient is sourced.

And the sourcing itself reflects the Greenwich standard. Chef Robert works with the region's finest suppliers: the premium Italian imports and artisanal pantry goods from DeCicco & Sons, the exceptional seafood counter at Fjord Fish Market in Greenwich, and the superior farm-fresh produce from Stew Leonard's in nearby Norwalk. For specialty cuts and whole animals like the rabbit at the heart of this evening's fourth course, he relies on the heritage-breed programs at Pat LaFrieda Meats. For a dinner like tonight's — a porchetta-style rabbit rooted in the mountain villages of Le Marche — this level of ingredient sourcing is not a luxury; it is the foundation.

The difference between Private Chef Robert and a catering company is not merely one of scale. A catering company arrives with a pre-built menu, plated in volume, and a team focused on service logistics. Chef Robert arrives with mise en place tailored to your kitchen, your guests, and your vision. He handles every aspect of preparation, cooking, plating, and kitchen cleanup — leaving your counters immaculate and your evening uninterrupted. There is no handoff to a banquet manager. There is no server hovering with a script. There is a chef who genuinely cares about the meal, and about your experience of the meal.

The emotional return on that investment is real and lasting. The time you reclaim — the hours you would have spent researching caterers, coordinating deliveries, managing prep, and cleaning up afterward — comes back to you as presence. You are at the table with your guests. You are part of the evening rather than the engine of it. Your guests, for their part, feel the difference immediately. Dinner tastes different when it is clearly made for them.

This evening's fourth course — Coniglio in Porchetta dei Sibillini, a rabbit rolled and roasted in the porchetta tradition of the Sibillini Mountains, served with rosemary-crisp Yukon Gold potatoes and bitter foraged chicory — is exactly the kind of dish that makes that point without a word. It is specific. It is accomplished. It arrives at the table with a story, and it invites your guests to ask where it came from. The recipe that follows is your invitation to explore it — and the number at the bottom of this page is how you bring Chef Robert's hands to the work.

Coniglio in Porchetta dei Sibillini con Patate al Rosmarino e Cicoria Selvatica

Course Secondi Piatti
Region Le Marche
Yield Serves 6
Total Time ~2 hrs 15 min
Difficulty Intermediate
A Note from Chef Robert — Coniglio in Porchetta is the dish that first made me fall in love with Le Marche. I encountered it in Amandola, a small hill town at the edge of the Sibillini Mountains, where a nonna had been making it the same way for sixty years — the rabbit butterflied and rolled with wild fennel, garlic, and rosemary until it perfumed the whole house before it even hit the oven. For a Greenwich dinner party, this dish does something remarkable: it is deeply rustic in its origins and completely elegant in execution. It rewards the table with something genuinely unexpected, and that surprise — that moment when a guest asks "what is this?" — is exactly what I live to create.

3a — Mise en Place: Organize Your Kitchen Before the First Cut

Set up three stations before beginning. Everything should be measured, prepped, and at its station before any heat touches the pan. This is how professional kitchens move with confidence.

❶ Cold Prep Station

  • 2 whole rabbits, butterflied & boned — kept cold
  • 2 lbs Yukon Gold potatoes, cut into 1½-inch chunks
  • 1½ lbs cicoria selvatica (chicory), washed, trimmed, and blanched
  • 3 tbsp wild fennel fronds, finely chopped
  • 2 tbsp fresh rosemary leaves, minced — divided use
  • 1 tbsp fresh thyme leaves
  • 8 garlic cloves, minced — plus 3 garlic cloves, thinly sliced (for chicory)
  • 4 cloves garlic, skin-on and smashed (for potatoes)
  • Zest of 1 lemon; juice of ½ lemon (for chicory finish)
  • Butcher's twine, cut into 10-inch lengths × 8 pieces

❷ Cheese & Pantry Station

  • 6 thin slices lardo or pancetta tesa
  • 1 tsp fennel pollen (or ½ tsp toasted fennel seeds, ground)
  • ½ tsp dried red pepper flakes — divided use
  • 2 tsp kosher salt — divided use
  • 1 tsp freshly ground black pepper — divided use
  • 6 tbsp extra-virgin olive oil — divided use
  • ¾ cup Verdicchio dei Castelli di Jesi (or dry white wine)
  • ½ cup chicken or rabbit stock
  • Fleur de sel — for finishing potatoes

❸ Cooking Station

  • Large heavy-bottomed roasting pan or Dutch oven (fits 2 rabbit rolls)
  • Large rimmed sheet pan (for potatoes)
  • 12-inch sauté pan (for chicory)
  • Instant-read thermometer
  • Kitchen timer × 2
  • Carving board with juice channel
  • Sharp boning knife
  • Ladle for basting

3b — Ingredients

For the Coniglio in Porchetta

  • 2 whole rabbits (approximately 2½ lbs each), butterflied, boned, and opened flat — ask your butcher
  • 8 cloves garlic, minced to a fine paste
  • 3 tablespoons wild fennel fronds (or cultivated fennel fronds), finely chopped
  • 1 teaspoon fennel pollen (substitute: ½ teaspoon toasted fennel seeds, ground)
  • 2 tablespoons fresh rosemary leaves, minced
  • 1 tablespoon fresh thyme leaves
  • ½ teaspoon dried red pepper flakes
  • 2 teaspoons kosher salt, plus more for seasoning
  • 1 teaspoon freshly ground black pepper
  • 6 thin slices lardo or pancetta tesa (for larding and wrapping)
  • 3 tablespoons extra-virgin olive oil
  • ¾ cup Verdicchio dei Castelli di Jesi or other dry white wine
  • ½ cup good chicken or rabbit stock

For the Patate al Rosmarino (Rosemary Roasted Potatoes)

  • 2 lbs Yukon Gold potatoes, scrubbed, cut into 1½-inch chunks
  • 4 cloves garlic, skin-on and gently smashed
  • 4 sprigs fresh rosemary
  • 3 tablespoons extra-virgin olive oil
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • Fleur de sel, to finish

For the Cicoria Selvatica (Wilted Foraged Chicory)

  • 1½ lbs cicoria selvatica — wild chicory, dandelion greens, escarole, or radicchio di campo
  • 3 cloves garlic, thinly sliced
  • 3 tablespoons extra-virgin olive oil
  • ¼ teaspoon dried red pepper flakes
  • Juice of ½ lemon
  • Kosher salt, to taste

3c — Method

  1. 1
    Preheat and Prepare the Herb Paste Position oven racks to accommodate both the rabbit roasting pan (middle rack) and the potato pan (lower third). Preheat oven to 375°F. In a small bowl, combine the minced garlic, chopped fennel fronds, fennel pollen, minced rosemary, thyme, red pepper flakes, 1½ teaspoons kosher salt, ½ teaspoon black pepper, and 1 tablespoon olive oil. Work together with a fork until it forms a coarse, fragrant paste — it should smell like the hillsides above Amandola on a warm morning.
  2. 2
    Season and Stuff the Rabbit Lay each butterflied rabbit skin-side down on your cutting board, patted completely dry with paper towels. Season the interior flesh lightly with salt. Spread half the herb paste evenly over the interior surface of each rabbit, all the way to the edges. Lay 3 slices of lardo lengthwise across the herb-coated flesh. The lardo will melt into the meat during roasting, keeping it moist and adding a subtle porcine richness that is entirely authentic to the porchetta tradition.
  3. 3
    Roll and Tie Starting from the longer side, roll each rabbit tightly and firmly into a cylinder, keeping the stuffing inside as you go. Tie with butcher's twine at 1-inch intervals — aim for 4 ties per roll. The finished rolls should be compact and hold their shape when pressed gently. A loose roll will unravel in the pan; a tight one will emerge golden and shapely, holding clean slices at service. Season the exterior of each roll generously with the remaining salt and pepper.
  4. 4
    Sear Until Deeply Golden Heat 2 tablespoons olive oil in your roasting pan or Dutch oven over medium-high heat until shimmering. Add both rabbit rolls and sear without moving them for 2–3 minutes per side, rotating to brown all four sides — approximately 8–10 minutes total. You are looking for a rich mahogany crust, not just pale gold — this is where the flavor lives. The kitchen will begin to smell extraordinary. That is the signal you want.
  5. 5
    Deglaze and Braise-Roast Remove the pan from direct heat. Pour in the white wine carefully — it will sputter and steam dramatically. Scrape up any browned bits from the pan bottom with a wooden spoon. Add the stock. The liquid should reach about one-third of the way up the rolls. Transfer to the preheated oven, uncovered. Roast for 55–65 minutes, basting with the pan juices every 20 minutes. The rolls are ready when the internal temperature reads 160°F and the skin has tightened to a crackled, amber finish.
  6. 6
    Roast the Rosemary Potatoes (concurrent) While the rabbit goes into the oven, toss the potato chunks on your sheet pan with 3 tablespoons olive oil, the smashed garlic, rosemary sprigs, salt, and pepper. Spread in a single layer with space between each piece. Roast on the lower rack at 375°F–400°F for 38–42 minutes, turning once at the 20-minute mark. The potatoes are done when the cut sides are deeply caramelized and crisp, and they yield completely when pressed with a spatula. Finish with a pinch of fleur de sel immediately from the oven.
  7. 7
    Blanch and Prepare the Cicoria Bring a large pot of well-salted water to a boil. Add the chicory greens and blanch for 2 minutes to remove bitterness and soften the leaves. Drain and press out excess moisture. In a 12-inch sauté pan, warm 3 tablespoons olive oil over medium heat. Add the sliced garlic and red pepper flakes and cook until the garlic turns faintly golden and fragrant, about 90 seconds. Add the blanched chicory and toss to coat. Cook for 3–4 minutes, until the leaves have wilted into a silky, cohesive tangle. Finish with the lemon juice and a pinch of salt. Taste — the bitterness should be present but gentle, a counterpoint to the richness of the rabbit.
  8. 8
    Rest the Rabbit and Reduce the Pan Sauce Remove the rabbit from the oven and transfer to a cutting board fitted with a juice channel. Tent loosely with foil and rest for 8–10 minutes before slicing. Do not skip this step — resting allows the juices to redistribute, keeping every slice succulent rather than dry. Meanwhile, place the roasting pan on a burner over medium heat and reduce the braising liquid until it thickens to a glossy, deeply savory film that coats the back of a spoon — about 3–4 minutes. Taste, adjust for salt, and keep warm.
  9. 9
    Slice and Plate Remove the twine from each rabbit roll. Using a sharp knife, cut each roll into ¾-inch medallions — you should get 6 to 7 clean rounds per roll. Each slice will reveal the green herb filling at its center, like a savory jelly roll from the mountains. Arrange 2–3 medallions per plate, overlapping gently. Spoon a small pool of reduced pan sauce beneath or around the medallions. Nestle a portion of rosemary potatoes alongside, and place the wilted cicoria on the opposite side as a counterpoint. Finish with a drizzle of your finest extra-virgin olive oil over the entire plate.
Plating & Garnish — For dinner party service, consider a warm, pre-heated plate. Garnish with a single fresh rosemary sprig, a scant pinch of fennel pollen dusted over the rabbit medallions, and two to three whole chicory leaves placed upright for height. The color palette — amber rabbit, golden potatoes, deep green chicory — speaks the language of the Italian countryside without a word of explanation.

3d — Time on Task

Stage Task Time
Mise en Place Butterflying & boning (butcher prep), herb paste, vegetable & chicory prep, station setup 40 minutes
Active Prep Seasoning, rolling, tying, searing, deglazing 20 minutes
Oven — Rabbit Braise-roast, basting twice 60 minutes
Oven — Potatoes (concurrent) Roasting alongside rabbit (staggered start by 20 min) 40 minutes
Stove — Chicory Blanch + sauté (concurrent with rest period) 10 minutes
Rest & Sauce Reduction Rabbit rests, pan sauce reduces 10 minutes
Plating & Service Slicing, plating, garnish, service 8 minutes
Total Time · Fridge to Table (with concurrent tasks) ~2 hours 15 minutes

Chef's note: Request that your butcher butterfly and bone the rabbits 24–48 hours in advance. The herb paste can be made the night before and refrigerated, covered. The assembled, tied rabbit rolls can also be prepared the morning of service and refrigerated uncovered on a rack to dry the exterior — this dramatically improves the sear and the finished crust.
