Jonnie Boer

Jonnie Boer (9 January 1965 – 23 April 2025) was a Dutch Michelin-starred head chef and co-owner of the restaurant De Librije in Zwolle, Netherlands.

Biography Boer was born in Giethoorn. Together with his wife and business partner Thérèse Boer he ran the 3-starred De Librije (in 16th century monastery library building ) and Librije's Winkel (cooking shop). They also owned Librije's Hotel and Librije's Atelier (cook- and wine school), all located in a former women's prison.

In 1989, Boer became head chef at De Librije. In 1992, he and his wife bought the restaurant. The Michelin Guide awarded the first star in 1993. Five years later, Michelin awarded Jonnie Boer his second star. In 2004 Boer was awarded his third star.

Jonnie Boer used nature as his source of inspiration to develop new dishes, but also as basis of his cooking.

Boer died of a pulmonary embolism on Bonaire, on 23 April 2025, at the age of 60.

Controversy In February 2011, the local paper De Stentor reported that Jonnie Boer was in financial trouble. Fact was that the Librije Group was hit by the economic recession and had to cut costs. The firebrand sale at order from the banks of restaurant Koperen Kees was nonsense, according to Jonnie Boer. Boer claimed that the sale of Koperen Kees was one of priorities, the theater-formula not fitting the philosophy of the rest of the Librije Group. Sander Dol became the new owner.
