All of those Sundays in front of the slow cooker have paid off for T-Mobile CEO John Legere — and fans of the recipes he dishes up as part of his weekly side gig. The Bellevue, Wash.-based wireless carrier announced the release Thursday of a new cookbook: “#SlowCookerSunday: Leadership, Life and Slow Cooking with CEO and Chef, John Legere.”

Born out of the Facebook Live cooking show that attracts more than 5 million viewers each week, Legere’s book is a collection of 52 of his favorite recipes — including stuffed shells with spinach, beef brats, veggie omelet and giant chocolate chip cookie.

“#SlowCookerSunday” also includes some of the Legere’s brash advice, whether you’re in the office or the kitchen, such as “Don’t be a chicken,” which includes “tips on making bolder moves at work and in the kitchen, plus non-chicken recipes like a melt-in-your-mouth pot roast, an easy apple cake and a corned beef and cabbage dish.”

Legere said viewers of his show have been telling him to do a cookbook and the so-called Un-CEO finally took his own advice, to shut up and listen.

“For me, ‘#SlowCookerSunday’ is so much more than a cookbook,” Legere said in a news release. “Sure, you’ll make incredible food with the recipes in it, get a little bit of advice, and laugh at old photos of me (in a suit!), but my favorite part is that you’ll be helping feed the hungry across the country.”

Net proceeds from sales of the book, which will retail for $19.99, are going to Feeding America. The book will sell on T-Mobile.com starting today and in T-Mobile stores nationwide beginning Friday.

Martha Stewart, who knows a thing or two about being a CEO and a kitchen diva, wrote the forward for the book. She previously starred in a Super Bowl commercial for T-Mobile alongside rapper Snoop Dogg.

“I have gone through this book with a fine-tooth comb and must admit that it’s pretty good!” Stewart wrote. “I like it because it’s more than just a book full of great recipes for cooking. It’s also a primer for all of us who want some great advice on how to be a great CEO and a successful entrepreneur.”

GeekWire previously went behind the scenes of “Slow Cooker Sunday” to watch Legere in action at his favorite restaurant, Din Tai Fung in Bellevue’s Lincoln Square. Check out that story and video below:
