Nadia Caterina Munno is the self-proclaimed The Pasta Queen. It’s a title she’s used over the past three years to accumulate a combined six million followers on various social-media platforms, where she posts boisterous, often ironic videos of herself prancing around in her enormous, blue steel and brass home kitchen, making Italian food and laughing at others’ attempts at making Italian food. But Ms. Munno, 40, is aiming much higher than TikTok celebrity. “I want to be the Italian Martha Stewart,” says Ms. Munno. Her cookbook made the New York Times bestseller list in November and she’s working on a second one.
