Preheat your oven to 425°F (218°C). Prepare a baking sheet by lining it with parchment paper for easy cleanup.
In a medium bowl, mix together the panko breadcrumbs, ranch dressing mix, garlic powder, onion powder, paprika, salt, and black pepper. Stir until the seasonings are evenly distributed throughout the breadcrumbs.
Dip each green bean in the beaten eggs, allowing any excess egg to drip off, then coat it in the breadcrumb mixture. Press gently to ensure the crumbs adhere well. Arrange the coated green beans in a single layer on the prepared baking sheet.
Once all green beans are coated, lightly mist them with olive oil spray to encourage even browning.
Bake the green beans in the preheated oven for about 10 minutes. Carefully remove the baking sheet, flip the green beans, then return them to the oven. Continue baking for another 2 to 5 minutes, or until they’re golden and crispy.
Serve these crunchy green beans warm and enjoy their flavorful, savory coating.
