Steven Redzikowski's Pumpkin Soup with Cinnamon-Spiced Marshmallow


Steven Redzikowski’s Pumpkin Soup with Cinnamon-Spiced Marshmallow

As the chef-owner of Denver’s new Acorn restaurant, as well as OAK at Fourteenth in Boulder, CO, Steven Redzikowski contends with some cold days. “Soup should always be one of, if not the, most seasonal things on the menu,” he says. “And it’s certainly something we turn to as soon as autumn hits and we want more warmth from our meals.”

Seasonal in autumn, of course, means winter squash and root vegetables, and so this season Redzikowski was quick to put his roasted pumpkin soup on his OAK menu. “People go bananas for it,” he says. “And we’ll use it at Acorn, but most likely as a sauce, because Acorn is more of a shared-plate restaurant, and in my opinion, soup isn’t the most terribly natural thing to share.”

What makes people crazy for Redzikowski’s pumpkin soup is its blend of savory and sweet. “When people cook a butternut squash soup or sweet potatoes, they’ll often use a little brown sugar,” he says. “We like to use our homemade marshmallow with pumpkin.” The soup stock (parsnip-based), which he makes after wood-firing herbs and roasted vegetables as well as pumpkin, is super smooth. “We blend the heck out of it,” he says. “Then we pour it, table-side, over a heated bowl that already contains smoky, blow-torched pieces of spiced marshmallow. When the soup hits the marshmallow, the sticky candy melts, and it creates a really nice sweet note without overpowering the nutty, earthiness of the pumpkin.”

Redzikowski’s tip for finding pumpkins is easy: They should be in most seasonal grocery stores come fall (yes, you can buy your marshmallows in a bag). And don’t worry about organic squash – you just want to find a pumpkin that hasn’t been sitting on its side for a while and/or looks a little flat or brown on one side. “It’s pretty easy to roast pumpkin,” Redzikowski says. “I won’t say you can’t overcook them, but it’s hard, and to find out if it’s done, I just stick a pairing knife into its thickest portion and make sure I can remove it without resistance. You want the flesh, like many a comforting cold-weather dish, to be super-tender.”
