Marinate 8 pieces of chicken breast (20 oz) with 1 tbsp olive oil, 2 tsp sriracha, 1/2 tsp paprika, 1/2 tsp garlic powder, 1/2 tsp pepper, and 1/4 tsp salt. Make sure every piece of chicken gets seasoned evenly. Preheat the air fryer to 350°F.
Beat 1 medium egg with 2 tbsp milk in a bowl.
Combine 1 tbsp melted butter, 1/2 cup breadcrumbs, and 0.25 oz parmesan in another bowl.
Place 1/4 cup all-purpose flour into a large dish. Take a piece of chicken with your dry hand, dip it in the flour, and shake to remove the excess.
Dredge it over the egg mixture with your wet hand, flip, and allow the excess to drip off.
Place it into the breadcrumbs, use your dry hand to sprinkle the breadcrumbs onto the chicken, then press to coat both of its sides. Place it onto a rack or a baking sheet. Repeat to coat the remaining pieces.
Lay all of the pieces into the air fryer basket in a single layer (fry multiple batches if necessary), and air-fry for 10 minutes. Flip at the 7th minute.
While the chicken’s cooking, combine 2 tbsp Japanese mayonnaise with 1 tbsp Greek yogurt in a bowl. Optional: toast the buns in a non-stick pan over medium heat until warm.
Assemble the burger and enjoy!
