Preheat your oven to 220°C (425°F) and line a baking sheet with parchment paper or foil.

Pat the chicken wings dry with paper towels to ensure they are moisture-free.

In a mixing bowl, combine olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper if desired. Toss the wings in this mixture.

Arrange the seasoned wings in a single layer on the prepared baking sheet or wire rack.

Roast the wings in the oven for 35–40 minutes, flipping halfway, until crispy and cooked through.

While wings bake, melt butter in a small saucepan over low heat, add minced garlic and cook until fragrant.

Toss the wings in the garlic butter after they are done.

Garnish with chopped parsley and serve immediately.
