Put the flour, eggs, and the breadcrumbs each separately in 3 shallow dishes.
Place each veal cutlet between two pieces of plastic wrap and pound with the flat side of a meat mallet until about ¼-inch thick.
Dip each piece into the flour and then shake off the excess. Next, run the cutlets through the egg to coat it lightly. Finally, press the cutlets in the breadcrumbs to coat.
Heat the oil in a large skillet over medium heat.
Cook the breaded cutlets until browned on each side, about 3 minutes per side. Lower the heat if necessary to keep the breading from burning.
Transfer to a paper towel-lined plate to drain.
Serve drizzled with lemon.
Notes
Have a butcher cut the cutlets for you or partially freeze the meat - it makes slicing it thin a breeze. You could also buy thinly pre-cut cutlets instead.
When dredging the meat, try and keep one hand dry and one wet so that the flour doesn't clump.
For less mess when coating the meat with flour and breadcrumbs, use food storage containers, close the lid, and then shake until coated.
Ensure that the cutlets are well coated in the breadcrumbs before frying.
Test that the oil is hot enough before adding the Wiener schnitzel to the pan. Drop in a couple of breadcrumbs; if they sizzle, the oil is hot enough.
Don't overcrowd the pan when frying; fry one or two at a time if your pan isn't big enough.
