Oster 6-Slice Toaster Oven 6058

The Oster 6-Slice Toaster Oven 6058 is a countertop cooking appliance designed for baking, convection baking, broiling, toasting, preparing pizza, dehydrating, and defrosting foods. Its electronic control panel provides separate cooking functions, adjustable time and temperature settings, and a digital clock display.

The toaster oven features a removable wire rack with three positioning options, a baking pan, a broiling rack, a removable crumb tray, and a glass door. The interior includes easy-clean walls and a built-in lamp for viewing food during operation.

The convection fan circulates heated air to help food cook more evenly and quickly. For everyday use, the toaster oven provides dedicated settings for toasting bread and bagels, preparing 9–12-inch pizzas, and using the Bake or Broil functions.

The appliance also includes preset temperatures for specific cooking functions. The Pizza setting operates at 400°F, Dehydrate at 185°F, and Defrost at 150°F.

The Oster 6058 is intended for household use and operates from a 120-volt AC electrical outlet. Proper rack placement, cooking settings, cleaning, and ventilation are important for safe operation and consistent cooking results.
