Oster Roaster Oven Cooking Times


  • Place the REMOVABLE ROASTING PAN into the ROASTER OVEN BODY. CAUTION: Do not cook food in the roaster without using the removable roasting pan.
  • Place the lid on the roaster.
  • Make sure that the TEMPERATURE CONTROL is in the OFF position, then plug cord into a 120 volt AC outlet.
  • Turn the roaster on by turning the TEMPERATURE CONTROL to the desired temperature.
  • Preheat for 15 to 20 minutes. Light will turn OFF once the set temperature is reached.
  • Place ROASTING RACK into the REMOVABLE ROASTING PAN, put food on the RACK, and place the LID on the roaster oven. NOTE: Some foods or recipes do not require the ROASTING RACK to be used.
  • When finished, turn the TEMPERATURE CONTROL to the OFF position and unplug roaster oven from outlet.
  • Remove LID and using oven mitts, remove the ROASTING RACK with food and serve.
  • Your Oster® Roaster features a unique Defrost setting. The Defrost setting is convenient for when you have forgotten to defrost your frozen turkey ahead of time or did not allow yourself enough time to fully defrost it in time to roast it. With this unique and innovative Defrost setting, you can to take your turkey from frozen to roasted in hours – not days!

    NOTE: In order to plan your day accordingly, when roasting a turkey from frozen you can estimate it will take around twice the time it would normally take to roast an already defrosted turkey in your roaster.

    It’s easy to use; just follow these few simple steps:

  • Turn temperature knob to “DEFROST.” Preheat roaster for about 15-20 minutes.
  • Unwrap your frozen turkey and place it on the roasting rack inside of roaster and place lid on top. Defrosting process begins. • Make sure to have a good meat thermometer to check defrosting temperatures from time to time; however, try not to open the lid too many times as it is important to keep as much heat as possible in the roaster while defrosting.
  • Check that legs and thighs have reached between 90°F and 100°F before basting. Once they do, brush the outside of the turkey with butter or oil and season with salt and pepper (see chart below for estimated times).
  • Continue cooking in the Defrost Setting until the thighs and legs reach at least 130°F to 150°F and the breast reaches at least 50°F to 60°F. (see chart below for estimated times). Once desired temperatures have been met, use a baster to remove any excess liquid or ice chunks remaining in the cavity. Then, using tongs, remove the bag of giblets and neck. Once removed, brush the outside with additional butter or oil.NOTE: If the giblets and neck are hard to remove at this time, let the turkey defrost slightly longer checking about every 10– 15 minutes until they can be removed relatively easily.
  • Now you are ready to start roasting. Turn the temperature knob to 325°F and roast your turkey (see chart below for estimated times). The turkey will be done roasting when the temperature of the breast reaches at least 165°F and the legs and thighs reach at least 175°F. The other important temperature to take is inside the cavity – it also needs to reach at least 165°F or you risk contaminating the rest of the bird when you carve it.NOTE: To check doneness of the turkey it is important to take temperature readings in different areas of the turkey to make sure it is all completely done. If any of the areas have not reached the temperatures noted above, let it roast for a little longer until they are reached, checking about every 10 – 15 minutes.
  • Above times are estimates and should be used as a guide to planning your total time using the defrost setting. Your best indicators at each stage are the temperatures the turkey reaches at each step using a good meat thermometer.

    NOTE: You might be wondering why it would take a smaller turkey longer than a larger turkey to roast once it is thawed and you have removed the neck and giblets. Your roaster defrost and roasting process is based on temperature and turkey size.

  • Larger turkeys – As the roaster is defrosting, it is also heating the turkey; since it takes longer to defrost a larger sized turkey; it also heats it longer therefore shortening the time to roast to completion.
  • Smaller turkeys – Since defrosting time for a smaller sized turkey is shorter, so is the heating time of the turkey; therefore, it takes longer to roast to completion.

  • Remove all packaging materials.
  • Wash the REMOVABLE ROASTING PAN, ROASTING RACK and LID in hot, soapy water using a sponge or wash cloth. Rinse and dry thoroughly. NOTE: Do not use abrasive cleaners.
  • The outside of the ROASTER OVEN BODY may be cleaned with a soft cloth and warm soapy water. CAUTION: Do not immerse the ROASTER OVEN BODY in water.

  • Always use pot holders or oven mitts when placing or removing food, a baking pan or casserole in the preheated roaster. CAUTION: Always lift the lid away from your body to avoid any escaping steam from the roaster.
  • Significant amounts of heat escape whenever the LID is removed; therefore the cooking time must be extended. Avoid frequent removal of the LID for checking cooking progress or stirring.
  • To use the LID REST feature, hold the LID upright by the HANDLE and place the edge of the LID under the metal tabs just above either side HANDLE.
  • The LID is designed with a glass viewing window that allows you to monitor cooking progress with ease. High-moisture foods such as turkey and roasts may cause condensation to form on the glass as the cooking cycle starts. This is temporary and the condensation will dissipate during the cooking process, providing a clear view of your food.
  • Convenience foods can be baked in the roaster oven. Place container on ROASTING RACK. Follow package directions.
  • Meats roasted in your Roaster Oven will be moist and tender. For additional browning, brush oil or butter over the meat before cooking.
  • To create a darker roasted, crispier skin poultry, remove your poultry from the roaster oven at the last 30 minutes of roasting time and place in your oven at 425⁰ F for the last 30 minutes to complete the roasting process.

    This appliance should be cleaned after every use.CAUTION: Do not immerse the ROASTER OVEN BODY in water or other liquid. Do not put REMOVABLE ROASTING PAN in dishwasher.

  • Turn temperature control to the “OFF” position.
  • Unplug the roaster oven from outlet and allow unit to cool.
  • Allow the roaster oven to cool completely before cleaning.
  • Wash the REMOVABLE ROASTING PAN, LID and ROASTING RACK in hot soapy water – using a sponge or cloth. Rinse thoroughly in hot water, then towel dry. NOTE: Do not use abrasive cleaners.
  • Wipe the inside and outside of the ROASTER OVEN BODY with a damp cloth.
  • USER MAINTENANCE: This appliance has no user serviceable parts. Any servicing beyond that described in the Cleaning Section should be performed by an Authorized Service Representative only. See Warranty Section.


    How long does it take to cook a roast in an electric roaster?

    Cook the roast at 300 degrees Fahrenheit for 15 to 30 minutes per pound, depending on whether you want rare, medium or well-done beef. Cook for 3 to 4 hours total for a well-done roast; the meat should fall apart when done.

    Does a roaster cook faster than an oven?

    Save Energy and Space

    Because an electric roaster oven is smaller than a conventional oven, it uses heat more efficiently. Roaster ovens takes 30 percent less time and uses 36 percent less energy based on average time and energy savings when using a roaster vs. a conventional oven.

    How long does a 17 lb turkey take to cook in a roaster?

    You’ll want to plan about 8-10 minutes per pound for an unstuffed bird at 325º Fahrenheit. You should always read your instruction manual because each roaster may be different.

    How long does a 20lb turkey take in a roaster?

    Simply turn the roaster down to 325 degrees thereafter. Roast for an additional 15 minutes per pound at 325 degrees. A 20-pound turkey will need about 4 ½ hours of roasting at the lower temperature.
