Prepare the Coating: In a large bowl, combine bread crumbs, grated Parmesan, and a pinch of cayenne. Mix these ingredients until evenly distributed. Add salt and pepper according to your taste preferences.
Dredge the Beans: Layout the flour on a plate. In a separate bowl, have the beaten eggs ready. Working in batches, first dredge the green beans in flour, ensuring a light coat.
Egg Wash: Dip the floured beans into the eggs. Use a slotted spoon or fork to lift the beans, letting any excess egg drip off.
Bread the Beans: Place the egg-dipped beans into the bread crumb mixture. Toss gently, pressing slightly to coat thoroughly.
Bake: Arrange the coated beans on a baking sheet in a single layer. Bake in the preheated oven at 425 degrees Fahrenheit for 10-12 minutes or until they are golden brown and crisp.
Serve: Enjoy these crispy delights fresh out of the oven, ideally while warm and crunchy.
