Preheat the oven: Start by preheating your oven to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease it with cooking spray.

In one shallow bowl, whisk together the flour, garlic powder, onion powder, paprika, black pepper, and a pinch of salt.

In a second bowl, beat the eggs until well combined.

In a third bowl, mix the panko breadcrumbs with the grated Parmesan cheese.

Working in batches, dredge each piece of chicken first in the seasoned flour, making sure it's fully coated.

Next, dip the floured chicken into the beaten eggs, allowing any excess to drip off.

Finally, roll the chicken in the panko-Parmesan mixture, pressing gently to ensure an even coating.

Arrange on the baking sheet: Place the coated chicken pieces on the prepared baking sheet, making sure they aren’t touching for maximum crispiness. Drizzle the tops lightly with olive oil, or use a cooking spray to evenly coat the surface of the chicken.

Bake for crispiness: Bake the chicken pieces for 18-20 minutes, turning them halfway through the cooking time. They should be golden brown and crispy on the outside, and the internal temperature should reach 165°F (74°C) to ensure they are fully cooked.

Mix the sauce: In a medium bowl, whisk together the mayonnaise, sour cream, and buttermilk until smooth and creamy. If you prefer a thicker sauce, omit the buttermilk, or adjust the amount to reach your desired consistency.

Add the flavor: Stir in the grated Parmesan cheese, ranch seasoning mix, fresh parsley, and lemon juice. Season with salt and pepper to taste.

Adjust the seasoning: Taste the sauce and adjust the seasoning as needed. If you like a more pronounced tang, add a little extra lemon juice. For a stronger ranch flavor, add more ranch seasoning.

Once the boneless wings are done baking, you have two options for serving:

Toss them in the sauce: For a fully coated experience, place the cooked boneless wings in a large bowl and pour the Ranch Parmesan Sauce over them. Toss until each piece is evenly coated with the sauce.

Drizzle with sauce: If you prefer a lighter touch, arrange the baked wings on a serving platter and drizzle the Ranch Parmesan Sauce on top. You can also serve the sauce on the side for dipping.
