There are a few key tips to make sure your wings come out crispy. First, pat the chicken dry with paper towels before baking. This helps remove any excess moisture that would otherwise make the skin soggy. Second, bake the wings in a single layer on a wire rack set inside a baking sheet. This allows hot air to circulate around the wings and helps them crisp up. Finally, if you want extra crispy wings, bake them for a few minutes longer until they're golden brown.
