In a large pot of boiling water, cook potatoes for 10 minutes. Then, add the corn to the boiling water with the potatoes.
Boil until the potatoes are finished, about 5 more minutes.
Drain corn and potatoes, and place them into a large bowl.
Clean and pat dry shrimp, and add them to the bowl. Also, add sausage to the bowl.
In a small bowl, combine butter with minced garlic and Old Bay seasoning. Pour the butter mixture over the shrimp boil ingredients and toss it all together.
Transfer everything to a large baking sheet and bake at 400 °F for about 15 minutes or until the shrimp is fully cooked. Serve with lemon wedges. ENJOY
