Heat the grill to medium heat. My grill was registering about 400-degrees.
Lay out the foil and brush the center of each piece with a little bit of olive oil.
Put a layer of the potatoes on the foil.
Next, add the sliced sausage and the shrimp on top of the potatoes.
Place a couple of pieces of corn on each side of the potatoes.
Sprinkle everything with the old bay seasoning and the fresh garlic if using.
Top off with a slice of lemon, another small drizzle of olive oil, and a small pat of butter.
Seal up the Shrimp Boil Packets. Crimp the edges well so that everything steams in the packet while cooking.
Place the packets on the grill and cook for about 20 minutes.
Remove the packets from the grill, poke small holes in each packet to let some of the steam escape. Let them set a couple of minutes then they are ready to serve.
Open Carefully! Top with a little of the sliced green onion.
If you use a different size shrimp, you may need to adjust the cooking time.
The red potatoes cut to 1-inch squares cook perfectly, as written above. If you want to use another type of potato or want bigger pieces, you may need to cook the potatoes a little bit before making the packets.
Remember to use heavy-duty aluminum foil and seal the packets well.
When grilling, rotate the packages halfway through cooking.
Try these packets with your favorite seasoning!
If you want to cook these packets in the oven, cook for 20 minutes with the oven set to 375 to 400-degrees F.
