Preheat oven to 400 degrees.
Place artichoke hearts in a large baking dish halved side up.
Sprinkle lemon zest on top of each half followed by the juice of half a lemon. (If you prefer a less lemony taste, use about a quarter of the lemon.)
Mound panko on each half, followed by the cheese mixture.
Drizzle with olive oil
Bake for ten minutes. Then turn on broiler until cheese is fully melted and golden. Serve immediately.
