Set your oven to 400°F (200°C).
Let it heat up completely.
This ensures even cooking throughout.
A hot oven gives the best results.
Pat the shrimp dry with paper towels.
Moisture prevents proper roasting.
Place them in a large mixing bowl.
Remove tails if you prefer easier eating.
Add olive oil to the bowl.
Toss in minced garlic immediately.
Add salt and black pepper generously.
Sprinkle red pepper flakes if you like heat.
Mix everything together really well.
Make sure each shrimp is coated evenly.
Line your baking sheet with parchment paper.
Spread shrimp in a single layer.
Don't overcrowd them on the sheet.
Space allows them to roast, not steam.
Place the sheet in your hot oven.
Roast for 8 to 10 minutes total.
The shrimp should turn pink and opaque.
Don't overcook or they'll become rubbery.
Check them at 8 minutes for doneness.
Remove from oven once they're done.
Squeeze fresh lemon juice over the shrimp.
Sprinkle chopped parsley on top for freshness.
Serve immediately while they're hot and delicious.
