Balthazar opened on April 21, 1997, at 80 Spring Street in SoHo. Keith McNally had already opened Odeon in Tribeca (1980) and Café Luxembourg on the Upper West Side (1983), but Balthazar was the one that remade his reputation. He built a French brasserie interior from scratch in a former textile warehouse — the mosaic tile floors, tin ceilings, scarred brass mirrors, and zinc bar were designed to look decades old on opening night — and the restaurant became an immediate New York institution. The Balthazar Bakery at the same address opened the same week, baking the bread and pastries for the restaurant and selling directly to the public before the kitchen opens each morning.
Weekend brunch is the hardest reservation in the house. Balthazar seats about 180 guests and has been fully booked on Saturday and Sunday mornings for most of its nearly three decades in SoHo. The brioche French toast is $24 on the brunch menu. The recipe below reproduces it as faithfully as possible at home: thick-cut bakery brioche, overnight custard soak, clarified butter, and a low-and-slow cook that finishes in the oven.
Three Things Most French Toast Recipes Get Wrong
Most French toast recipes dip the bread in custard for 30 seconds and cook it immediately over high heat in whole butter. Against thick brioche, that approach produces toast that is eggy and surface-coated on the outside and still dry bread in the center. The Balthazar version — and really any good brioche French toast — requires three things that most home recipes skip.
Overnight soak. A 2-inch brioche slice does not absorb custard in 30 seconds, or even 30 minutes. To fully saturate thick brioche, it needs 4 hours minimum and is best soaked overnight. The overnight soak transforms the interior into something closer to bread pudding: the custard distributes evenly through the crumb, and the finished slice has that yielding, custardy core rather than the dry-bread-with-wet-exterior texture of a quick-dipped version.
Day-old brioche. Fresh brioche is too moist and too soft to hold up to an extended soak. It will absorb custard, but it will also partially dissolve, producing a soggy, torn slice that falls apart when you try to cook it. Brioche that has had 24 hours to air-dry has a firmer structure — the gluten has stiffened slightly and the crumb can absorb without collapsing. If you are making this same-day, slice the brioche 3 to 4 hours before soaking and leave it uncovered on a wire rack to dry slightly.
Clarified butter and oven finish. Whole butter has milk solids that burn at low temperatures. For thick French toast, you need to cook it low and slow — 3 to 4 minutes per side over medium-low heat — to build a golden crust without burning the exterior while the thick interior sets. Whole butter will turn dark before the crust is properly caramelized. Clarified butter has no milk solids; its smoke point is over 400°F, which lets you maintain steady medium-low heat for as long as you need. The oven finish (6 to 8 minutes at 350°F) is what fully sets the custard in the center of a 2-inch slice — stovetop heat alone cannot penetrate that far without over-cooking the outside.
About the Custard
The ratio here is 1 cup heavy cream to 3 eggs. This is on the cream-heavy end of the French toast spectrum: more cream and fewer eggs produces a custard that sets softer and silkier, with a richer mouthfeel, rather than the firmer, more egg-forward result of a higher-egg ratio. For bakery-quality brioche, this is the right call — the custard should enhance the bread’s butteriness rather than compete with it.
Nutmeg is present at a background level — 1/4 teaspoon freshly grated for the whole batch. You should not be able to identify it in the finished dish; its role is to add a faint warmth that makes the custard taste like something from a pastry kitchen rather than something from a home kitchen. Fresh-grated nutmeg from a whole nut is significantly more aromatic than pre-ground; if you have a whole nutmeg, use it.
The Maple Syrup Matters
Grade A Dark Color/Robust Taste maple syrup — formerly called Grade B — is the correct choice alongside this dish. It has a pronounced, complex maple flavor that registers clearly against the rich custard and butter. Grade A Medium Amber is too mild; it adds sweetness without depth. Pure maple syrup only: pancake syrup is corn syrup flavored with artificial maple extract, and it will taste obviously wrong against a dish this well-made.
