To prepare a wiener schnitzel breaded veal cutlets recipe, first preheat the oven to 450?F (232?C) and prepare the breading. Heat the olive oil in the skillet over medium-high heat. Add the chopped onion and cook, stirring frequently, until the onion is translucent, about 5 minutes. Remove the pan from the heat and add the garlic and saute until fragrant, 1 minute. Pour the flour into the mixture and stir until it's evenly coated. Season with salt and pepper to taste. Set aside.
