Gregg Wallace is reported to be almost £300,000 out of pocket after the parent company controlling the now-closed Wallace & Co restaurant in Putney went into voluntary liquidation.
Companies House documents showed that Wallace Cafes Ltd still owes £93,000 to creditors.
A sale of stock, fittings and other assets is expected to raise around £65,000.
Wallace & Co closed in January this year. It is not the first of the MasterChef co-host's businesses to collapse - Gregg's Bar and Grill in Bermondsey in August last year, while his greengrocers business West Veg had £500,000 worth of debts when it went into administration in March 2013.
