Preheat oven to 375°F (190°C).
In a bowl, toss chicken thighs with olive oil, salt, pepper, garlic powder, onion powder, and paprika.
Place on a baking sheet and bake for 45 minutes. Broil for the last 2 minutes for extra crispiness.
While chicken bakes, mix together Kewpie mayo, sugar-free sweet chili sauce, and Sriracha.
Brush sauce over cooked chicken and return to oven for 2 more minutes.
Garnish with parsley flakes and serve hot.
