Add 2 large eggs and ½ cup milk of choice to one large shallow bowl. Whisk wet ingredients together vigorously until mixture is pale in color and eggs are no longer streaky. Set bowl aside.
Add 1 cup all-purpose flour, salt, freshly cracked black pepper, 1 teaspoon paprika, ½ teaspoon garlic powder, and ½ teaspoon onion powder to second large shallow bowl. Whisk dry ingredients together until well blended. Set bowl aside.
One by one, dip chicken pieces in egg mixture, coating all sides completely. Hold chicken piece over bowl, allowing excess egg mixture to drip back into bowl, then place chicken in breading mixture. Flip and roll chicken in dry ingredients, coating well on all sides.
Shake any excess breading mixture back into bowl, then return chicken to egg wash and repeat process. Coat chicken in egg wash on all sides, then let excess egg wash drip back into bowl before placing chicken in breading mixture. Gently press breading onto chicken to ensure breading sticks on all sides.
Shake excess breading back into bowl, then transfer chicken to baking sheet or large plate. Repeat breading process with remaining chicken, coating each piece in egg wash, then breading, then egg wash again, and then breading again.
Once all chicken pieces have been fully breaded and placed on baking sheet or plate, place baking sheet or plate in refrigerator. Chill chicken 20 minutes.
