Instant Pot Shrimp Boil
This Instant Pot Shrimp Boil delivers juicy Cajun-spiced shrimp, baby potatoes, corn, and smoky sausage in one pot, ready in under 30 minutes for the easiest seafood boil ever.
The Easiest Instant Pot Shrimp Boil You Will Ever Make
There is something magical about a classic shrimp boil. The smell of Cajun spices, the way the corn soaks up all that buttery broth, the sausage that somehow tastes better after a quick simmer. Normally this means babysitting a giant pot on the stove for half an hour, but this Instant Pot Shrimp Boil gets you all that flavor in a fraction of the time. If you have been searching for instant pot shrimp recipes that actually deliver on the classic seafood boil experience, this is the one to bookmark.
What makes this version so good is the order of operations. The potatoes, sausage, and corn go in first to pressure cook together, then the shrimp get added at the very end so they stay tender and never turn rubbery. It is a small trick that makes a huge difference, and it is exactly why this instapot seafood boil recipe works so reliably every single time.
Before we get cooking, the right tools and ingredients make a real difference here. A good pressure cooker with a reliable seal, fresh Cajun seasoning, and shrimp that have not been previously frozen and refrozen will all push this dish from good to genuinely unforgettable. These are the products that genuinely help this recipe shine:
Why This Recipe Works So Well in the Instant Pot
Pressure cooking is perfect for a shrimp boil because it cooks the potatoes through quickly while infusing everything with the broth, garlic, and lemon sitting at the bottom. Unlike the stovetop version, there is no need to babysit a rolling boil or worry about overcooked corn.
- The potatoes and sausage get a full 5 minutes of pressure to become tender and smoky.
- The corn rides on top, so it steams instead of getting waterlogged.
- The shrimp go in last and gently cook in the residual steam, which is the secret to perfectly tender shrimp every time.
Chef's Tip: Never pressure cook the shrimp with everything else. Shrimp cook in just a couple of minutes, and adding them at the very end after a quick release is the single biggest difference between rubbery shrimp and tender, juicy ones.
A Few Notes on Ingredients
This recipe is wonderfully forgiving, which is part of why so many people search for an instapot shrimp boil easy enough for a weeknight. Andouille sausage brings the most authentic flavor, but kielbasa works in a pinch. Old Bay is optional, but it adds a briny depth that pairs beautifully with the Cajun seasoning. Fresh corn is ideal, but frozen corn on the cob can go in straight from the freezer.
For the shrimp themselves, look for ones labeled large or extra large, since smaller shrimp can overcook before the rest of the dish is ready. Leaving the tails on also makes for a more dramatic presentation if you are serving this family style.

Instant Pot Shrimp Boil
This Instant Pot Shrimp Boil delivers juicy Cajun-spiced shrimp, baby potatoes, corn, and smoky sausage in one pot, ready in under 30 minutes for the easiest seafood boil ever.
Ingredients
- 1 lb baby potatoes, halved if larger than golf ball size
- 3/4 lb andouille sausage, sliced into 1-inch rounds
- 4 corn on the cob, halved or quartered
- 1 lb large shrimp, peeled and deveined, tails on
- 2 tbsp Cajun seasoning, plus more to taste
- 1 tbsp Old Bay seasoning, optional but recommended
- 4 garlic cloves, smashed
- 1 lemon, halved, plus wedges for serving
- 1 cup chicken broth, or water
- 4 tbsp unsalted butter, melted, for serving
- 2 tbsp fresh parsley, chopped, for garnish
Instruction
Add the chicken broth to the Instant Pot, then add the smashed garlic and squeeze in the juice from the halved lemon, tossing the lemon halves in too.
Layer in the baby potatoes and sliced andouille sausage, then sprinkle with half of the Cajun seasoning and the Old Bay seasoning.
Place the corn pieces on top, then lock the lid and set the valve to sealing. Cook on high pressure for 5 minutes.
Quick release the pressure as soon as cooking finishes, then carefully open the lid.
Add the raw shrimp directly on top of the potatoes and corn, sprinkle with the remaining Cajun seasoning, then close the lid (no need to seal) and let the residual heat steam the shrimp for 3 to 5 minutes, or use the saute function briefly if needed, until the shrimp are pink and opaque.
Drain any excess liquid if desired, then transfer everything to a large platter or pour directly onto a newspaper-lined table.
Drizzle with melted butter, scatter fresh parsley over the top, and serve immediately with extra lemon wedges.
Equipment
- Instant Pot or electric pressure cooker (6-quart or larger)
- Tongs
- Large serving platter
- Sharp knife and cutting board
Notes
Serving and Storage Tips
The best way to serve this is the messy, fun way. Pour the entire contents onto a newspaper-lined table or a large platter, drizzle with melted butter, and let everyone dig in with their hands. A pile of napkins and a few extra lemon wedges go a long way.
If you somehow end up with leftovers, store them in an airtight container in the fridge for up to two days. Reheat gently in a skillet rather than the microwave, since high heat can make the shrimp tough. This insta pot shrimp boil recipe also reheats nicely as a next-day seafood hash if you chop everything up and crisp it in a pan with a little extra butter.
Easy Variations to Try
- Swap shrimp for a mix of shrimp and crab legs for an even bigger seafood boil.
- Add a splash of beer instead of part of the broth for deeper flavor.
- Toss in a few dashes of hot sauce or extra cayenne if you like things spicier.
However you customize it, this is the kind of recipe that turns a regular dinner into an event. Once you try this method, you will understand why so many home cooks now consider it their go-to among instant pot recipes shrimp lovers swear by.
