Kathy Sidell’s Tips and Recipes for a Nantucket Dinner Party

The best part of a party at Saltie Girl owner Kathy Sidell’s Nantucket home? Everyone’s invited.

About an hour before her dinner guests are set to arrive, Kathy Sidell hears an unexpected knock at the door of her Nantucket home. The restaurateur behind the buzzy Back Bay seafood bar Saltie Girl peeks outside and sees a fisherman friend, cooler in hand after a long day at sea. He’s stopping by to ask if Sidell and her husband, Carl Goldberg, would like a piece of the enormous bluefin tuna he just reeled in. As the unmistakable aroma of grilled lamb in the air suggests, however, Sidell has already made more than enough food for the intimate group of family and friends gathering to dine. Perhaps he’d like to join them? Regrettably, he can’t, but he doesn’t leave before insisting she take a thick slab of fish for another meal.

It’s moments like this that make Sidell feel as at home here on Nantucket as she does in Boston. After decades of renting on the island, Sidell and Goldberg are celebrating their first full season in their Monomoy summer home. It’s been a long time coming for the couple, who purchased the land in 2003 but didn’t finish construction on the house until last year. “We started to build restaurants in 2004, which explains why we got sidetracked,” says Sidell, who operates hot spots in Boston, Dedham, and Natick, and on Nantucket. Still, the long delay allowed Sidell and Goldberg to think through every aspect of the home’s design. Naturally, the kitchen is a focal point, outfitted with a Wolf range, a La Cornue rotisserie, and blue-and-white tiles reminiscent of those on Saltie Girl’s distinctive back bar.

As islanders and visiting family members begin to arrive, Sidell suggests everyone head to the living room for strawberry-rhubarb rum cocktails and seasonal starters such as crab-avocado-and-burrata toast, a favorite at Saltie Girl. Soon it’s time to stroll outside to the patio, where gold-rimmed plates atop a wood table rest beside vases filled with flowers snipped from the yard. All eyes quickly turn to a side table set with a family-style spread, including lamb cooked on the wood-burning grill and risotto carbonara, served in a carved-out Parmigiano-Reggiano wheel. “With each scoop, you get more cheese,” Sidell notes with delight as she heaps the truffle-topped risotto onto her plate. As the sun begins to set and glasses clink, Sidell slips in a few words: “I’m kind of pinching myself right now,” she says. “Honestly, waiting all these years has made moving in that much sweeter. You plant the seeds, and slowly, surely, it happens.” Finally, it’s time to eat.
