During an appearance on ‘Cooking with the Stars,’ the rock legend’s son spoke about growing up with pro chefs cooking their meals

Jack Osbourne is reflecting on his late dad Ozzy Osbourne’s eating habits.

During an Aug. 3 TV appearance on the U.K. food show Cooking with the Stars — filmed before his father’s death — Jack, 39, spoke about growing up in a house where professional chefs often cooked the family’s meals.

“I grew up on potato waffles until we moved to America,” he said, recalling how he, Ozzy, mom Sharon and sisters Aimee and Kelly moved to the U.S. from England when he was around 11 years old. “We would get take out all the time — apart from times when we had a chef.”

Jack joked that the Black Sabbath frontman never employed any one chef for a long time, as he was a “picky eater” who would suddenly decide: “‘No, I don’t like it anymore,’ even though it’s some amazing chef.”

Osbourne died on July 22 at 76 years old. Jack publicly mourned his father’s death alongside his mother and siblings on the Black Sabbath bridge and bench in Birmingham, England.

Ozzy had been diagnosed with Parkinson’s disease in 2023. Before his death, he performed his final Black Sabbath concert in early July.

A source close to the family also told PEOPLE that the rocker was to be honored by his family with a funeral befitting the star’s infectious spirit.

“They’re very grateful for the special family time they had together before Ozzy passed,” the source said last week. “They’re planning a small, private funeral that will be a celebration of his life. Ozzy would never want a mope-fest.”

The source added that the rocker’s family is “touched by all the love and support pouring in from around the world.”

Although Jack hasn’t yet spoken publicly about his father’s death, a number of other Osbourne family members have looked back on Ozzy’s life — including Jack’s ex-wife Lisa Stelly.

Stelly posted a touching tribute on Instagram of Ozzy with his grandchildren throughout the years. From painting in the house to flying in a private jet, the proud mom of three shared several special memories of Ozzy enjoying being a grandfather.

Stelly, 38, reposted the post onto her Instagram Stories, adding “Love you, Papa” in text and Ozzy’s 1995 song, “See You on the Other Side.”

Daughter Kelly, 40, also posted a photo on her Instagram Stories on Aug. 1, showing a flower display crafted in honor of Ozzy.

An arrangement of purple flowers that spelled out “Ozzy F—— Osbourne” could be seen in the social media post.

The florals were similar to those that were laid at the hearse at Ozzy’s funeral.

Kelly previously shared a poignant tribute to her dad on her Instagram Stories on July 24, posting lyrics from the Black Sabbath song “Changes,” which she and Ozzy recorded their own version of in 2003.

“I feel unhappy I am so sad,” Kelly wrote in her social media post. “I lost the best friend I ever had .”
