Preheat your oven to 425°F. Line a baking sheet with parchment paper and spray it with cooking spray.
In one bowl (or a zip-top bag), mix the flour with 1 teaspoon of the seasoned salt. In a second bowl, whisk the eggs.
In a third bowl, combine the panko, Parmesan cheese, and the remaining ¼ teaspoon of seasoned salt. Stir in the olive oil until the crumbs are evenly coated.
Working in batches, toss the chicken pieces in the flour mixture until fully coated. Shake off the extra.
Dip the floured chicken into the egg, coating it completely. use a fork to lift the chicken out of the bowl and let the excess egg drip off.
Next, coat the chicken in the breadcrumb mixture, pressing gently to help the crumbs stick. Make sure the entire nugget is coated and no bare spots are present.
Place the coated nuggets on the prepared baking sheet, and spray the tops of the nuggets with cooking spray.
Repeat the coating and breading process until all the nuggets are breaded and sprayed with cooking spray. All the nuggets should be in an even layer on the baking sheet, with room for air to circulate around each piece of chicken.
Bake for 10 minutes, then flip the nuggets, and finish baking for another 5–7 minutes, or until golden brown and cooked through (the internal temp should be 165°F).
Optional: For extra crispy browned nuggets, broil them on HIGH for 1-2 more minutes to turn the crumbs a deep golden brown.
Let the nuggets cool for a few minutes before serving.
