The Duchess of Sussex on Tuesday confirmed she would co-host Junior MasterChef - Masterchef Australia's mini-me spin-off - over its 2027 season.
The channel is rebooting the program after six years off the air.
The former actress dropped into Flemington's Centenary Hall in 2026 to judge an episode of the grown-up competition.
Contestants were challenged to transform a staple ingredient into a dish "fit for a duchess".
The episode drew Masterchef's biggest Sunday audience since 2023.
Meghan said a return to Australian TV was an "easy yes".
"I love cooking with my own kids, so seeing what these young stars create in the kitchen is going to be a lot of fun," she said in a statement.
"I can't wait to see what they cook up."
The Duchess of Sussex previously earned a Daytime Emmy nomination for her Netflix show, With Love, Meghan.
It featured cooking, entertaining and gardening segments with occasional celebrity appearances.
The show aired for two seasons in 2025 - including a single holiday special - after the duke and duchess quit as senior working royals in 2020.
The duchess also once appeared as a guest judge on a children's cooking show in the US.
Meghan will join celebrated Malaysian-Australian chef and presenter Poh Ling Yeow on the show, which is expected to begin filming in 2027.
Ling Yeow said she was thrilled the show would return to air.
"People often ask me whether it might come back," she said.
"I know the news will be met with plenty of excitement."
"I had a lovely time filming with (Meghan) earlier this year, and being reunited will be a real treat."
Ten is unveiling its 2027 programming line-up over the week.
