A cooked spoon roast lasts three to four days in a refrigerator set to 40 F or lower. Alternatively, it is safe to store a cooked spoon roast in the freezer for between two and six months.
Cooked meat must be placed in the refrigerator within two hours of taking it out of the oven to keep bacteria at bay. However, if the room temperature is 90 F or over, the meat should not sit out for more than one hour. Secure, airtight wrapping ensures that the meat remains fresh for as long as possible and that its juices don't interfere with the quality of other foods.
