Use in both toaster ovens and countertop ovens. Ideal for cooking one or two servings. The majority of toaster ovens sold in the last five years did not come with proper fitting bakeware. The outer dimensions of our toaster oven bakeware are eight by ten inches. A baking sheet, a roasting pan, a crisper pan are sold separately and as a set. Roast meat, vegetables, potatoes. Bake small casseroles; a petite batch of cookies; dainty, crispy crust pizzas; crispy chicken nuggets and much more.
