Raise your hand if you've ever set off your smoke detectors while trying to create the char you get from outdoor grilling inside. I know I have! The Foodi Grill comes with a unique system to control the smoke. The temperature-controlled grill grate, splatter shield, and cool-air zone work together to reduce the amount of smoke and keep your kitchen almost smoke-free. Of course, if you have too much fat at too high of a heat, it can cause smoke. For this reason, I recommend adding oil directly to the food (in this case, asparagus stalks) and not the grill pan itself.
