Chili Dog Casserole in NuWave Oven
Countertop convection ovens circulate air rapidly via a top-mounted heating element and fan. Exposing an 8x8 silicone baking pan directly to this intense radiant heat scorches cheese before the interior warms. Covering the dish with aluminum foil for the initial ten minutes traps steam, allowing the tortillas and franks to reach a safe internal threshold without desiccating the exterior.
Flour tortillas contain starches that readily absorb moisture from canned chili. Placing the rolled franks seam-side down prevents the tortilla wrappers from unfurling as the starch molecules hydrate and expand during the high-power cooking cycle. Keeping the layer of chili distributed evenly beneath and above the rolls ensures the ambient humidity softens the wrapper uniformly.
Evaluating doneness relies entirely on visual inspection since inserting a thermometer into thin hotdogs yields inaccurate readings. Removing the foil during the final five minutes exposes the cheddar cheese to direct radiant heat until butterfat separates and the surface bubbles aggressively. Look for distinct browning around the edges of the pan alongside a thick consistency in the surrounding chili.
