In a medium bowl, toss shrimp, olive oil, salt, pepper, garlic, rosemary, lemon zest and chile flakes to combine.
Transfer the shrimp to a oven-proof dish and spread out in a single layer (or as close to it as possible).
Roast until the shrimp are pink and just cooked through, about 5 minutes. Serve immediately.
