You know, when you think of the humble air fryer, you might think it's only useful for making delicious fried delicacies without the grease, sans the name! But the air fryer can do so much more. Just look at the new cookbook from Becky Abbott and Jennifer West titled Air Fryer All Day. Both stopped by Tonia's Kitchen to talk about a very fall-like casserole that really brings on the flavor no matter the season. Both told Tonia it's called the Harvest Casserole, and as the name says, it offers the flavors of fall like apples, sausage onions and cinnamon. All you have to do is bring those ingredients together in the air fryer and set for 300 Degrees for 25 minutes. Both Becky and Jennifer says everyone who's tried it, loved it!
