Preheat the oven to 400°F and line a baking sheet with parchment paper.
In a medium-sized bowl, whisk together the flour, 1 teaspoon of sea salt, paprika, garlic powder, onion powder, cayenne, and ground black pepper until fully combined.
In another bowl, combine the breadcrumbs and the remaining teaspoon of salt, and whisk to combine.
In a third bowl, whisk together the eggs and milk until well combined.
Dip the chicken nuggets into the flour mixture and coat on all sides, then dip them into the egg mixture. Remove the nuggets from the egg wash and let any excess egg wash drip off. Transfer the chicken to the bowl with the breadcrumbs and toss to coat, then place the chicken on the parchment paper-lined baking sheet.
Spray (or drizzle) the chicken with olive oil, then bake for 15 minutes, flip, and bake for an additional 10-15 minutes, until golden and crisp.
Serve and enjoy!
