Preheat oven to 425°F. Line a rimmed sheet pan with parchment.
Drain artichokes well and pat very dry with towels.
Stir together panko, Parmesan, olive oil, garlic, lemon zest, paprika, salt, and pepper.
Toss artichokes with lemon juice, then add to the bowl and coat evenly.
Spread in a single layer, cut sides up, on the prepared pan.
Bake 15 minutes. Flip and bake 3–5 minutes more, until golden and crisp.
Broil 1 minute for extra crunch if needed. Sprinkle parsley and serve hot.
