The actress and TV talk show host admits she has become an "obsessed foodie" in recent years and loves discovering new dishes.
And she's giving some serious thought to compiling her favourite recipes into her very own book.
"My mom, who I only lived with until a certain early time in my life, was a California vegetarian from the 70s," Drew tells People. "She was very into that crunchy granola, vegetables, clean eating kind of stuff, and I still eat that way predominantly today."
"I started travelling the world, educating myself about food, learning who my favourite chefs were, and trying different restaurants. And that inspired me to then eventually start cooking in my 30s and 40s."
The "Santa Clarita Diet" star reveals she now has a whole closet devoted to cookbooks, and teased she might have her own in the works.
"Cookbooks are like schoolbooks for me, and I read them front to back," Drew adds. "I love the stories. I love learning a technique."
And while fans might have to wait for Drew's book to get their hands on her cooking tips, she is already passing on advice to her daughters, Olive and Frankie.
"[Olive] makes an incredible breakfast. She makes eggs, and veggie sausages, and toast," the proud mum says. "I recently posted an Instagram [photo], where I showed a breakfast she made for me when I was sick. She did it a hundred per cent on her own, and it meant so much to me."
