Step 1

Pour water into the bottom of the Instant Pot.

Step 2

Add in the potatoes in an even layer. Sprinkle about half of the Old Bay/seasonings over the potatoes. Add in the sausage in an even layer. Add in the green beans in an even layer. Sprinkle the beans with half of the remaining seasonings. Add in the corn in an even layer. Sprinkle the corn with the rest of the seasonings. Add in the butter on top of the corn. If using shrimp add it on top.

Step 3

Cover and secure the lid. Make sure the valve is set to sealing. Set the manual/pressure cook button to 1 minute. The pot will take a while to come to pressure. Once the minute of pressure cook time is up move the valve to venting. Remove the lid.

Step 4

Toss the contents of the pot with tongs. Scoop onto serving dishes. Drizzle a tablespoon of the drippings onto each serving.
