Ingredients
- 1 tablespoon salt
 - 4 to 6 red potatoes, quartered
 - 3 ears of corn, cut in half
 - 1/2 cup unsalted butter
 - 1/2 tablespoon Old Bay seasoning
 - 1/2 teaspoon cayenne pepper
 - 1/2 teaspoon garlic salt
 - 1/2 teaspoon onion powder
 - 1/2 teaspoon smoked paprika
 - 1/2 teaspoon freshly ground black pepper
 - 1/4 teaspoon mustard powder
 - 1/4 teaspoon dried oregano
 - 5 garlic cloves, minced
 - 1 pound Andouille sausage, cut into 1-inch-thick pieces
 - 1/2 pound medium to large shrimp, peeled, tail-on, deveined
 - 2 tablespoons chopped fresh parsley
 - 2 lemons, quartered
 
Directions
- Preheat the oven to 400ºF.
 - In a large pot, combine the salt with 5 cups of water and bring to a boil over medium-high heat. Add the potatoes and boil until fork tender, 7 to 10 minutes. Add the corn and boil until brighter in color and the kernels appear more plump, 3 to 5 minutes. Drain the water from the pot and set the vegetables aside.
 - Melt the butter in a microwave-safe dish. Whisk in the Old Bay, cayenne, garlic salt, onion powder, smoked paprika, black pepper, mustard powder, oregano, and minced garlic until well combined.
 - On a large sheet pan, spread out the sausage, shrimp, corn, and potatoes. Pour the seasoned butter over the sheet pan and mix all the components together until well coated.
 - Bake for 7 minutes, carefully remove from the oven, and gently stir components. Place back in the oven and bake until the shrimp is pink, about 5 minutes.
 - Garnish with the parsley and serve with the lemon wedges.
 - Store leftovers in an airtight container in the refrigerator for up to 2 days.
