Step 1

Preheat your oven to 400℉.  Line a large, rimmed baking sheet with parchment paper.

Step 2

Place shrimp in a large bowl and toss with olive oil and garlic.

Step 3

Spread the shrimp out onto the prepared pan.  It's okay if they are snuggled next to each other.  Sprinkle with rosemary, salt and pepper.

Step 4

Bake for 8 to 10 minutes, depending on the size of your shrimp.  The shrimp will curl up and turn pink when done.
