Prepare the ingredients by rinsing the shrimp and cutting the corn and potatoes.
Fill a large pot with water and add salt, seafood seasoning, and halved lemon.
Bring the pot to a rolling boil over high heat.
Add the potatoes and cook for 10 minutes.
Add the sausage and corn, cooking for an additional 5 minutes.
Finally, add the shrimp and cook until they turn pink, about 3-4 minutes.
Turn off the heat and let the pot sit for 5 minutes for flavors to meld.
Carefully drain the shrimp boil into a colander and transfer to a large platter.
Serve with additional lemon wedges and dipping sauces, if desired.
