In a small bowl, mix together ⅓ cup panko breadcrumbs, 1 tsp italian seasoning (if using), and ¼ cup parmesan cheese. Set aside.
Slice zucchini into rounds, approximately ⅓" thick. Add to a medium bowl. Add 2 Tbsp. olive oil and a sprinkle of salt and pepper and toss until rounds are fully coated. You may want to use a fork or your hands to separate them if they stick together to make sure they're fully coated.
Grab each round and press them into the panko mixture on both sides to coat in crumbs. Lay them evenly spaced out across a parchment-paper lined sheet pan. Repeat with all the rounds.
Bake at 350° for 20-25 minutes or until cheese mixture takes on a golden color.
