If you're preparing several foods that get "done" at different times, you often can successfully hold most hot foods for about 15 to 20 minutes in a preheated oven set to 200 to 250°F. For longer than this, check frequently with a food thermometer, to assure the food is remaining at a temperatures of 140°F or above. If necessary, adjust the oven's temperature to a higher setting. Keeping foods hot for extended periods (more than a couple of hours) may reduce the quality of the food. Examples of ways to keep foods warm include
