Jonnie Boer (born January 9, 1965, in Giethoorn) is a Dutch Michelin star winning head chef and co-owner of the restaurant De Librije in Zwolle, Netherlands.

[5] Jonnie Boer uses nature as his source of inspiration to develop new dishes, but also as basis of his cooking.

[6][7] In February 2011 the local paper De Stentor reported that Jonnie Boer was in financial trouble.

The firebrand sale at order from the banks of restaurant Koperen Kees was nonsense, according to Jonnie Boer.

[8] Boer claimed that the sale of Koperen Kees was one of priorities, the theater-formula not fitting with the philosophy of the rest of the Librije Group.
