Step 1: Prepare the Wings
Pat the chicken wings completely dry using paper towels. This is the most important step for achieving crispy skin! Place them in a large mixing bowl. Any moisture on the surface will prevent crisping, so really take your time with this step.

Step 2: Season the Wings
Add the baking powder, salt, black pepper, and garlic powder (if using) to the bowl with the wings. Toss thoroughly until every wing is evenly coated. The mixture should look slightly powdery on the surface – this is exactly what you want!

Step 3: Prepare Your Baking Setup
Line a large baking sheet with aluminum foil (for easier cleanup) and place a wire cooling rack on top. Arrange the wings on the rack in a single layer, making sure they’re not touching. Space is crucial for air circulation and even crisping. Use two baking sheets if needed.

Step 4: Refrigerate (Optional but Recommended)
For extra-crispy wings, refrigerate the seasoned wings uncovered on the rack for 30 minutes to 2 hours. This dries out the skin even more. If you’re short on time, you can skip this and bake immediately.

Step 5: Preheat and Bake
Preheat your oven to 250°F. Bake the wings at this low temperature for 30 minutes. This rendering process melts out the fat under the skin.

Step 6: Increase Heat
After 30 minutes, increase the oven temperature to 425°F and bake for an additional 20 minutes until the wings are golden brown and crispy.

Step 7: Flip and Finish
Carefully flip each wing using tongs and bake for another 10-15 minutes until deeply golden, crispy, and cooked through (internal temperature should reach 165°F).

Step 8: Make the Garlic Butter Sauce
While the wings finish cooking, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 1-2 minutes, stirring constantly, until fragrant but not browned. Remove from heat and stir in the parsley, red pepper flakes (if using), and lemon juice (if using).

Step 9: Toss and Serve
Transfer the hot, crispy wings to a large clean bowl. Pour the garlic butter sauce over the wings and toss gently to coat. Sprinkle with freshly grated Parmesan cheese and toss again. Taste and add more salt if needed.

Step 10: Serve Immediately
Transfer to a serving platter and garnish with additional parsley and Parmesan if desired. Serve hot with your favorite dipping sauces and plenty of napkins!
