Mike Sheerin, executive chef of Chicago’s Embeya restaurant, and the soon-to-come Packed dumpling house, has been making the mashed potatoes at his family’s Thanksgiving gatherings since he was six years old. “I had the unfortunate timing of catching my mother on the phone with one of her sisters in California,” Sheerin laughs, recounting that first mashed moment. “She was trying to mash the potatoes and talk on the phone at the same time—and this was before cordless phones.” Giving up on the effort, Mike’s mom handed him a towel, poured milk and butter in the hot potatoes, “And I went to town mashing them,” says Sheerin. “I kept pushing down the masher and lifting just enough to catch a little air to lighten them. I wasn’t even thinking about what I was doing at the time, but somehow, they were pretty amazing.”
In the decades since, Sheerin personally perfected methods for marvelous mashed potatoes still include an old-fashioned masher–but also finish with this liquid gold gravy. Made with roasted bones from a turkey carcass, onion, garlic, white wine, thyme and lots of mushrooms, Sheerin’s rich gravy is worth the effort. I roast a small turkey days before Thanksgiving, save the meat for after-holiday casseroles and sandwiches, and use the carcass specifically to make this gravy. It means a lot less last-minute scrambling the day of the event. Bonus: View our marvelous mashed potatoes recipe using best-of methods from Mike and Chicago Chef Matthias Merges.
