In an air fryer combine sweet potatoes, onion and apple.
Pour in 2 tbsp oil, 1 tsp garlic powder, 1 tsp thyme, 1 tbsp maple syrup, 1 tsp salt and ¼ tsp pepper and toss to coat.
Air fry for 8 minutes at 400 degrees.
While that is cooking, in a bowl combine chicken thighs, 2 tbsp oil, 1 tbsp champagne vinegar, 1 tsp salt, 1 tsp garlic powder and 1 tbsp maple syrup and toss to coat.
When sweet potatoes are done, stir them to disperse and place chicken thighs on top of them in a single layer.
Place back in the air fryer for 10 minutes, then flip the chicken and cook an additional 5 minutes.
