Her new cookbook, Trisha Yearwood's Georgia Cooking in an Oklahoma Kitchen, hit No. 3 on the New York Times Bestseller List this week in the "Advice, How-To & Miscellaneous" category. It's the week's top selling cookbook. In a statement, Yearwood said she was "overwhelmed" by the response.
Co-authored with her mother, Gwen, and sister Beth, the book began as a scrapbook of favorite family recipes put together for Trisha, 43, when she moved to Oklahoma to live with husband Garth Brooks, 46. Specialties include Gwen's Fried Chicken with Milk Gravy, Daddy's Biscuits and Just-Married Pound Cake.
The first-time author told PEOPLE earlier this year, "I love to cook – it's second to music, my greatest passion. You make a dish and serve it and everybody goes, 'Oh my gosh it's the best!' and you feel like you've been given a standing ovation!"
Her secret ingredient? "Garth always says it's about cooking with love," Yearwood said. "He said that food just tastes better when you can tell someone that loves you made it. It's true!"
Yearwood – whose favorite recipe is for Thanksgiving Cornbread Dressing – joked that the book was as much for her own family as for anyone else. "My mother and sister and I had so many recipes that we all loved that weren't written down," she said. "So even if nobody but my mom bought this book, it's just good to get these all in one place!"
