Roaster ovens are versatile tabletop appliances that can bake, roast, steam and slow cook food in temperatures ranging from 200 to 450 degrees. Unlike toaster ovens and other small appliances, a toaster oven will consistently hold the correct low temperatures needed for safe slow cooking throughout the day. Use a classic slow cooker recipe like a stew or casserole, and you can create meals hours ahead of time without purchasing a separate slow cooking appliance.
Things You'll Need
Search through a specialized slow cooker recipe book for a recipe your family will enjoy. While most oven-baked and stove top recipes can be converted to the slow cooker, the timing can be tricky if you are not familiar with the process. If you are new to slow cooking, use a slow cooker recipe.
Preheat your roaster oven. If your recipe calls for cooking on the low setting, preheat the roaster to 200 degrees. If your recipe requires a high setting, preheat to 300 degrees.
Place the food into your roaster oven in the correct order. Food cooks at different rates in a slow cooker, so food that takes longer, like root vegetables, must be placed on the bottom, closest to the source of heat. Place meat on top of vegetables, and pour sauce ingredients over the top of everything else.
Cook your food in the roaster oven the same way you would if it were in a basic slow cooker. Do not remove the lid during cooking, as this releases heat and increases cooking time by as much as half an hour.
