Cut chicken into bite-sized cubes.
Make them about 2 inches each.
Pat them dry with paper towels.
This helps the coating stick better.
Mix Parmesan cheese and mayonnaise in a bowl.
Add garlic powder and onion powder.
Stir until everything blends smoothly.
Season with salt and pepper.
Toss chicken pieces in the mixture.
Make sure each piece is fully covered.
The coating should be thick and creamy.
Preheat your oven to 375°F.
Line your baking sheet with parchment paper.
Place coated chicken pieces on the sheet.
Space them out evenly. Bake for 25-30 minutes.
They should turn golden brown.
Check that internal temperature reaches 165°F.
