Brandon Clark: The Only Husband She Ever Had
Alex met Brandon Clark in 2006 while teaching a fish class at New York’s Institute of Culinary Education. Clark, then a lawyer exploring a possible career change, impressed her enough that she hired him part-time at Butter. Romance followed quickly. They married on April 29, 2007, at the restaurant where their relationship began. Their daughter, Ava Simone Clark, arrived that July.
The marriage lasted until 2015. After the divorce the pair kept co-parenting amicably. Clark stepped away from cooking after a kitchen injury and returned to law and other interests, while Alex continued raising Ava largely as a single mother. Reports of difficulties during the marriage circulated at the time, but both parents have kept the focus on their daughter rather than public drama.
The Engagement That Didn’t Become a Marriage
In the years after her divorce, Alex began dating fellow chef Michael Castellon around 2016–2017. They met when she complimented a steak at the restaurant where he worked. The relationship stayed relatively private until June 2020, when Castellon proposed on her birthday during a casual stop near their home. Alex publicly confirmed the engagement, and the culinary community celebrated the news.
The engagement ended in February 2022. Castellon confirmed the split and wished her well. Alex later spoke openly about the emotional difficulty of the breakup. No wedding ever took place, and the two have not reunited.
Life as a Single Mother and Professional Powerhouse
Alex and Brandon share one child, Ava, who turned 19 in July 2026. Mother and daughter have collaborated on a cookbook and appear close in public posts. Alex has repeatedly described parenthood as the experience that made her want to become a better person and a better cook. She continues to balance television work, restaurant responsibilities, book projects, and recent collaborations such as a limited-time menu for Hilton Garden Inn.
As of late 2025 and into 2026, there are no confirmed reports of a new long-term partner. Alex has kept her personal life private while remaining active and visible in her professional world.
