Creating the Sheet Pan Shrimp Boil is a straightforward process if you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper for easy cleanup.
2. Prepare Vegetables: In a large bowl, toss together the halved potatoes, corn, and sliced sausage. Drizzle with half the melted butter, and sprinkle with 1 tablespoon of Old Bay seasoning, paprika, salt, and pepper. Mix well to coat.
3. Spread on Sheet Pan: Spread the potato and sausage mixture evenly across the prepared sheet pan. Make sure to leave space for the shrimp.
4. Roast: Bake in the preheated oven for about 20 minutes, until the potatoes are nearly tender.
5. Add Shrimp: While the vegetables are baking, in a separate bowl, combine the shrimp, remaining butter, minced garlic, lemon juice, and the remaining Old Bay seasoning. Toss until well-coated.
6. Combine and Finish Cooking: After 20 minutes, remove the pan from the oven and add the shrimp mixture on top of the vegetables. Spread evenly and return to the oven for an additional 5-10 minutes, until the shrimp are pink and cooked through.
7. Garnish: Remove from the oven and garnish with freshly chopped parsley. Squeeze lemon wedges over the top for extra zest.
8. Serve: Serve directly from the sheet pan for a fun and casual dining experience.

By following these steps, you will create a delectable Sheet Pan Shrimp Boil that is packed with flavor and completely satisfying.
