Set up a small bowl of whisked egg and place panko and flour, respectively, on small plates.
Mix the garlic powder, sea salt, and cayenne pepper into the panko.
Pat zucchini slices dry and, working in batches, dredge the discs in flour. Dip the floured zucchini discs in the egg mixture, then the panko. Repeat for all, coating evenly and pressing the panko mixture into the disc as needed.
Place in a single, even layer on a baking sheet spritzed or rubbed with oil *OR* for extra crispy zucchini chips, spritz the chips with spray oil and place on a wire rack atop the baking sheet. Love this trick!
Bake until browned and crisp, approx. 25-30 minutes on the center rack. For extra even crisping, feel free to flip them over halfway through the cooking process if you're baking them right on the baking sheet.
Once they're golden and crispy, remove from oven and top with a drizzle of red hot sauce and a sprinkling of cheese.
Return to the oven and continue to bake (or switch it to broil if you'd like!) until cheese is hot and melty. You can skip the cheese entirely if preferred and can even just dip the zucchini chips in buffalo sauce if you want them to stay super crispy for longer.
Sprinkle with chopped parsley for an optional garnish and dive in while they're HOT with your favorite dressing or dip! I like to add sriracha to ranch dressing as a dip - so good!
