Heat oven to 375 degrees F. Line a sheet pan with aluminum foil or parchment paper. Coat with light layer of oil and set aside.
In a large ziplock bag, combine the breadcrumbs, salt, garlic powder, paprika, and black pepper.
Working in small batches (about 5-8), dredge brussels sprouts in flour, dip into egg mixture and place in ziplock bag. Shake ziplock bag until the sprouts are fully coated in bread crumbs and remove sprouts one by one onto pre-paired baking sheet. Repeat with remaining brussels sprouts.
Drizzle sprouts with a light drizzle of olive oil and bake for 25-30 minutes, flipping half way, until golden and crispy.
