This product is designed for household use only – When using electrical appliances, basic safety precautions should always be followed, including the following:

  2. Do not touch hot surfaces. Use handles or knobs.
  3. To protect against electrical shock and personal injury, do not immerse this appliance, including cord and plug, in water or other liquid.
  4. Close supervision is necessary when any appliance is used by or near children.
  5. Unplug from the outlet when not in use and before cleaning. Allow to cool completely before putting on or taking off parts, and before cleaning.
  6. Do not operate any appliance with a damaged cord or plug or after the appliance malfunctions or has been damaged in any manner. To avoid hazards, return the appliance to NESCO® Factory Service Department for examination, repair, or adjustment.
  7. The use of accessory attachments not recommended by the manufacturer may result in fire, electric shock, or injury to persons.
  8. Do not use outdoors.
  9. Do not let the cord hang over the edge of the table or counter, or touch hot surfaces.
  10. Do not place on or near a hot gas or electrical burner or in a heated oven.

Polarized Plug:
This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, the plug is intended to fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not try to modify the plug in any way.

Short Cord Instructions:
A short power supply cord is provided to reduce the risk resulting from becoming entangled in or tripping over a longer cord. Extension cords may be used if care is exercised in their use. If an extension cord is used, the marked electrical rating of the cord should be at least as great as the electrical rating of the appliance. The longer cord should be arranged so that it will not drape over the tabletop where it can be pulled on by children or tripped over unintentionally.

Get To Know Your Roaster Oven

COVER: Heavy gauge high-profile aluminum Cover is designed to control heat and moisture efficiently. Two vent holes are provided for air circulation. Note: When lifting the Cover, tilt it away to divert escaping steam. RACK: The removable chrome-plated steel or non-stick coated Rack is designed for better baking and fat-free roasting. COOKWELL: The porcelain enamel or non-stick Cookwell has a full 18-quart capacity. It is removable for easy clean up in the dishwasher or sink, or food storage in the refrigerator.

The side of the Roaster Oven contains the exclusive “CIRCLE OF HEAT” element for even, moist cooking, plus the added advantage of thick insulation and a full-range automatic oven temperature control. DO NOT PLACE FOOD DIRECTLY IN THE HEATWELL, ONLY USE THE COOKWELL. AUTOMATIC TEMPERATURE CONTROL: Regulates cooking temperature to maintain the dial setting in the Roaster Oven interior.

The conveniently placed guide gives recommended temperatures for slow cooking, roasting, baking, steaming, and serving. SIGNAL LIGHT: The glow of the signal light indicates the Roaster Oven is heating. When the desired temperature is reached, the signal light goes out. It goes off and on during cooking, indicating that the temperature is being maintained.

How to Use and Care for Your Roaster Oven
before using it for the first time

  1. Unpack your NESCO® Roaster Oven completely and REMOVE ALL PACKAGING MATERIAL AND INFORMATION LABELS. Place the Roaster Oven in a VENTILATED AREA ON A HEAT RESISTANT SURFACE. Set the control dial to its minimum setting. Plug the cord into a 120-volt AC outlet. Return control to the maximum setting (450ºF). Operate the Roaster Oven empty (without the Cookwell or Cover) for approximately 60 minutes, or until any odor or smoking disappears. Some smoke and odor are a normal part of “curing” the element and will not reoccur in cooking use. When curing is completed, turn the temperature control to its lowest setting, unplug the unit from the electrical outlet, and allow it to cool.
  2. Wash the Cover, Cookwell, and Rack in warm sudsy water, then rinse and dry. Refer to the complete cleaning instructions on the next page.
  3. NON-STICK COOKWELL: When ‘curing’ your Roaster Oven with a non-stick Cookwell, we recommend that it be operated WITHOUT COVER AND COOKWELL. Do this in a covered outside area or other well-ventilated area. After curing and cleaning, and before cooking in your non-stick Cookwell for the first time, lightly coat the interior of the Cookwell with vegetable oil.
To Operate Your Roaster Oven
  1. Place the Cookwell into the Heatwell. Always use the Cookwell for food. NEVER PLACE FOOD DIRECTLY IN THE HEATWELL.
  2. Preheating is recommended. To preheat, place the Cookwell into the heat well and cover. Set the control dial to its minimum setting. Plug into a 120-volt AC outlet. Reset the temperature control to the desired temperature. Preheat for 20 minutes. Carefully, using hot pads, add food to the Cookwell.
  3. The Rack may be used for baking or fat-free roasting. Other foods, such as soups and stews, are prepared without the Rack.
  4. Replace the Cover. Always cook with the Cover in place.
  5. If the Roaster Oven has not been preheated, turn the temperature control to its lowest setting. Plug the cord into a 120-volt AC outlet. Set the temperature control to the desired temperature. Fill the Cookwell with food as desired.
  6. Cook the food for the desired amount of time. When finished, turn the temperature control to its lowest setting, and unplug the cord from the 120-volt outlet. Allow the Roaster Oven to cool and clean as recommended below. THE COOKWELL, COVER, AND ACCUMULATED STEAM WILL BE HOT. USE CAUTION AND HOT PADS TO LIFT COVER OR REMOVE COOKWELL FROM HEATWELL.

Care and Cleaning

  1. After the NESCO® Roaster Oven has cooled, remove the Cover, Rack (if used) and Cookwell. Wash in warm sudsy water or place in the dishwasher. CAUTION–do not put a Cover in the dishwasher.
  2. Cooked-on food may be removed by using a non-abrasive cleaning pad and non-abrasive cleansers. Do not use abrasive cleaners or steel wool as porcelain enamel or non-stick finish may scratch. Use a plastic scrubbing pad to remove stains or cooked-on foods, and also to clean the steel Rack. HINT: To easily remove baked-on food residue, place Cookwell in Heatwell; then fill Cookwell with hot water. Cover and heat at 350ºF for 30 minutes. Turn off and allow to cool completely. Wash the cookwell as directed above.
  3. NEVER IMMERSE THE ROASTER OVEN IN WATER. To clean, wipe the outside of the Roaster Oven with a damp cloth and dry. Do not use abrasive cleansers on exterior surfaces.
  4. PORCELAIN ENAMEL COOKWELL has a strong finish and provides easy cleaning and years of use. It will not stain and stays attractive, even when used often.
  5. Avoid cutting food in the cookwell. The use of a non-stick spray on the interior surface is optional. Avoid storing items in the Cookwell which may scratch the surface. When roasting or baking at high temperatures, you may notice an irregular band of discoloration around the sidewalls of the Cookwell. This discoloration is characteristic of the super tough, nonstick coating used on the interior of the Cookwell and in no way affects the performance or durability of the finish. With continued use, the discoloration will become less noticeable.
Helpful Hints


  • Roasting meat in your NESCO® Roaster Oven keeps it moist and tender.
  • For additional browning, you can add 1 tbsp. browning sauce to oil and brush over skin before roasting.
  • • To sear meat: Preheat the Roaster Oven at 450ºF. Add margarine. Cover, then sear meat for 10 to 15 minutes per side until lightly browned. Stir ground meat once. Time will vary depending on the quantity of meat. Alternative browning method for self-basting turkeys. Preheat at 400°F for 20 minutes. Roast bird for 1 hour at 400°F. Reduce heat to 350° using the time in the chart, 13 – 18 minutes per pound. During the last hour of Roasting increase the temperature to 400°F and remove all excess juices from the bottom of the cook well.


  • Follow recipe directions for temperature settings.
  • Cut-up meats and vegetables should be of uniform size pieces.
  • Remember, little moisture escapes during cooking, so add additional liquid sparingly.
  • When slow cooking, heat is very gradual.
  • To convert a standard recipe to slow cooking: for each 30 minutes required in a standard recipe, slow cook about 1-1/2 hours at 200ºF to 250ºF.
  • When slow-cooking meats and poultry, it is not necessary to use the Rack. The low temperature prevents the meat from sticking to the bottom of the Cookwell.
  • Remember, little moisture escapes during slow cooking so add additional liquid sparingly.
