Break the corn into 2-3 inch pieces. I found it hard to break, so if you decide to cut it, be careful.
Cut the sausage into 1/4" slices
Wash and then quarter or halve the potatoes, depending on the size (keep the skin on the potatoes).
Wash the shrimp (seafood). I didn't take the shells off but you can.
Chop the green onions and finely chop the parsley
Butter Sauce
Melt the stick of butter in a microwave-safe bowl in the microwave for about 1 minute.
Combine the butter with the spices
Prepare & Assemble
Line a baking sheet with aluminum foil
Drizzle about 2 tablespoons of olive oil onto the foil. I used my clean hands to spread it around but you can also use a pastry brush or the back of a wooden spoon.
Mix potatoes with 1/3 of the butter mixture. I did it in a bowl but you can also do it right on the baking sheet, being careful not to rip the foil. Make sure the potatoes are in a single layer
Put in preheated oven for 30 minutes, turning 1/2 way through
After 30 minutes, add the corn with another 1/3 of the butter mixture. Combine with potatoes and put back into the oven for 15 minutes. Again, make sure it's in a single layer.
Add the last 1/3 of the butter to the shrimp and the sausage, and stir in with the juice of 1/2 a lemon.
Lastly add the shrimp and sausage mixture to the pan, stirring well, making sure it's still a single layer and put back into the oven for the last 15 minutes
I prepped all of my ingredients in three different bowls all at once when the butter was still melted. It made a little more mess but worked better for me.
Garnish with parsley, green onions and lemon wedges
