- Preheat your oven to 250°F and line a baking sheet with foil. Set a wire rack on top and lightly oil it. 
- In a large bowl, toss the wings with baking powder and salt until evenly coated. 
- Arrange wings skin-side up on the rack in a single layer. Don’t crowd ‘em—space is key for crispiness. 
- Bake at 250°F for 30 minutes, then increase oven to 425°F and continue baking for 40–50 minutes until skin is crispy and brown. 
- Let rest for 5 minutes. Toss in your favorite sauce or serve as-is.
