*Note: These instructions don't call for dipping the chicken in flour before the egg. Skipping flour produces a thinner, crispier crust rather than a thick, shell-like coating, I've found skipping the flour works particularly well for baking or air-frying, allowing for a lighter result.
Cut the chicken: Cut the chicken breasts into 1½ to 2-inch cubes. Set aside.
2½ lbs. boneless skinless chicken breasts
Season the chicken: Add the chicken to a bowl with the seasonings and olive oil. Toss to combine so the chicken is coated evenly. Allow to marinate for ~15 minutes at room temperature. Start Timer
1 tsp. garlic powder, 1 tsp. onion powder, 1 tsp. kosher salt, 1/4 tsp. paprika, Adjust seasonings based on preference, 1/4 tsp. black pepper
Set up dipping station: Mix the breadcrumbs and parmesan together in a bowl, and whisk the eggs in another bowl. Note: if you feel the panko crumbs are large, you can place the panko in a zip-lock bag with a rolling pin to ensure that the crumbs are just the right size for an even coating.
1¾ cup panko breadcrumbs, 1 cup freshly grated parmesan, 2 large eggs
Dip: Dip the chicken lightly in the egg, allowing excess to drip off, then toss in the breadcrumb mixture, pressing gently to adhere.
Air fryer method: Preheat to 400°F. Spray the basket lightly with oil and arrange the chicken in a single layer. Cook for ~8-10 minutes (flip halfway through cooking) or until chicken is golden and internal temperature reaches 165°F with a meat thermometer. Start Timer
1 Tbsp. olive oil
Oven method: Preheat the oven to 425°F. Line a baking sheet with foil and place a rack on top. Bake for 8 minutes on one side, and ~6-8 minutes on the other side or until the internal temperature reaches 165°F with a meat thermometer. Start Timer
Garlic butter: Mix melted butter with garlic, parsley, and chili flakes.
1/2 cup unsalted butter, 5-6 garlic cloves, 1 Tbsp. dried parsley or Italian seasoning, Pinch red pepper flakes
For both methods: Once cooked, brush the garlic butter sauce on the chicken (or right before you plan to serve).
Finish and serve: Add more parmesan and parsley on top and serve with ranch or garlic aioli. These are really good as an appetizer or wrapped up in a tortilla wrap with lettuce, tomatoes, aioli, and cheese.
More grated Parmesan to garnish on top
