Kwame Onwuachi’s All Hours cookbook is out September 22, 2026, from Knopf. Coauthored with Joshua David Stein, the 288-page book is priced at $40 in hardcover and is built around recipes for every part of the day, from breakfast and snacks to dinner and dessert.
Penguin Random House lists All Hours as available September 22 and describes it as a collection of home recipes designed for everything from quiet nights in to parties, cookouts and late-night eating. The publisher also lists Onwuachi on tour, including an All Hours Show event at Lincoln Center in New York on September 22.
What is in Kwame Onwuachi’s All Hours cookbook?
The book is organized around different eating moments rather than a single cuisine or meal type. Penguin Random House highlights recipes including Corn Milk French Toast, Curried Chicken Patties, Drunken Noodles alla Vodka, Berbere Chicken, Cosmic Brownie and Sticky Toffee Pudding.
The publisher says the book also includes dishes connected to Onwuachi’s restaurants as well as his takes on New York classics. One example specifically cited is Tatiana’s Cosmic Brownie.
Penguin Random House’s official book page lists the hardcover at $40, with 288 pages, ISBN 9780593802588 and publication by Knopf.
Why the release matters now
The key development is the book’s publication on September 22, not an older announcement resurfacing. Penguin Random House’s current release listings show All Hours becoming available today, while Onwuachi’s official author page places the All Hours Show in New York on the same date.
The launch also extends Onwuachi’s food media work beyond his restaurants. He previously published My America and Notes from a Young Black Chef, while All Hours focuses specifically on home cooking across a full day.
Is This Confirmed?
Yes. The publication date, publisher, price, page count and authorship are all confirmed by Penguin Random House, the publisher’s official source. The September 22 New York event is also listed on Onwuachi’s official Penguin Random House author page.
Recipes & Cooking recently covered other celebrity-food projects, including David Chang’s new CNN food travel series and Katie Lee’s UNEMPLOYABLE book launch.
