Prepare the chicken breasts by pounding them to about 1/2-inch thick.
Set up a breading station with three shallow dishes: one for flour, one for beaten eggs, and one for breadcrumbs.
Season the flour with salt, pepper, garlic powder, and onion powder.
Dredge each chicken breast in the flour, shake off excess, dip into the eggs, then coat with breadcrumbs.
Heat oil in a large skillet over medium heat until shimmering.
Carefully place the breaded chicken cutlets in the hot oil, cooking in batches if necessary to avoid overcrowding.
Fry each side for 4-5 minutes or until perfectly golden.
Remove the cutlets and place them on paper towels to drain excess oil.
