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

Pat your chicken wings dry with paper towels and place them in a large bowl.

Combine olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper in a smaller bowl. Pour over chicken wings and toss thoroughly.

Lay the coated wings in a single layer on the prepared baking sheet, ensuring they are spaced apart.

Roast the wings for 35–40 minutes, flipping halfway through until skin is crisp and internal temperature reaches 75°C (165°F).

While the wings bake, melt unsalted butter in a small saucepan over low heat. Add minced garlic and sauté for 1–2 minutes.

Transfer the roasted wings to a large bowl and drizzle the garlic butter over them, tossing to coat.

Garnish with chopped parsley if desired and serve immediately.
