Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easier cleanup.
In a large mixing bowl, combine the olive oil, minced garlic, lemon zest, lemon juice, smoked paprika, red pepper flakes, salt, and black pepper. Mix until well combined.
Add the shrimp to the bowl and toss until they are evenly coated in the marinade. Let the shrimp sit for about 15 minutes to absorb the flavors.
Spread the marinated shrimp in a single layer on the prepared baking sheet.
Roast the shrimp in the preheated oven for 8-10 minutes, or until they turn pink and opaque. Be careful not to overcook them as they can become tough.
Remove from the oven and sprinkle with fresh parsley for garnish before serving.
Notes
Be careful not to overcook the shrimp to avoid toughness.
