It’s faster to cook tater tots in the air fryer, there’s no long preheating time for the oven, and the air fryer won’t heat up the whole kitchen as an oven does! To be honest, I store a bunch of sheet pans in my oven, so it’s always a production to get the oven going. So if I can make something in my air fryer, then I’m usually taking the air fryer route. It’s also much crispier, as I mentioned earlier. The tater tots aren’t as crispy when I cook them in the oven.
