Why do I love roast winter vegetables? For starters, because they are fresh, local, and seasonal. Unlike summer produce, they keep for a long time without losing most of their flavor. They feel like winter food: hearty, substantial, rib-sticking. Francis Mallmann quick-roasts them at very high heat in a wood oven until they almost burn. A home oven doesn't put out that kind of thousand-degree heat, but when something as simple as slices of Delicata squash are coated with a little bit of olive oil, sprinkled with kosher or coarse sea salt, and then roasted, they come out of the oven chewy, nutty, sweet, and savory. Part caramelization, part umami, and part Maillard.
This dish is a slight adaptation of a recipe in Yotam Ottolenghi's Plenty, which I came across when I was asked to be a judge in Food52.com's "Tournament of Cookbooks." In case you don't know Yotam Ottolenghi's work—you'd never forget such a fun name—he is a London-based Israeli chef who writes a vegetarian column for the Guardian. He is not a vegetarian himself, which makes me trust his recipes even more. In other words, he is neither ideological nor moralistic about it: his only aim is food that tastes great.
Caramelized and well-seasoned winter vegetables are fine by themselves, but the maple-mustard vinaigrette lifts the flavors enormously. We made this recipe for a New Year's Eve dinner, and afterward I received ooh-and-aah e-mails from people about "the best vegetables ever!"
For sure, the company, the wine, and the other food had something to do with the reviews. But, taking all that into consideration, tell me, honestly, how often are people moved to praise a parsnip?
A few years ago I would have said you need your own roast tomatoes for this recipe, but now I find that Desert Glory or similar deeply flavored cherry tomatoes, though they don't hold a candle to real summer tomatoes, are fine when caramelized.
