Instant Pot Low Country Shrimp Boil
We love going to those restaurants that dump the shrimp boil right on the table. Then they hand you a bib and a mallet and leave you to just dive in!
You can have the same experience in your own home. This pressure cooker shrimp boil is an Instant Pot dump and start recipe, so it’s easy to make.
Which potatoes are the best to use?
Baby red potatoes and small new potatoes are the best as they cook to the perfect tenderness!
If you use larger potatoes, it would be good to cut them in half or quarters for faster cooking, and to help the rest of the ingredients fit in the pot.
What size of shrimp work best in Instant Pot Low Country Shrimp Boil?
I like to use Extra Large 26/30 shrimp, or Large 31/35. The number refers to how many shrimp per pound. Small number = larger shrimp.
I have the best results using frozen shrimp. The pot is very full, so it takes a long time to come to pressure. The shrimp thaws in that warmup time.
If you are interested in learning more about shrimp sizes and such, my friend Jessica Gavin, a Culinary Scientist, has a very good article you may like to read: Types and Sizes of Shrimp.
Here’s how easy it is to make Instant Pot Low Country Shrimp Boil:
If you are using small, unfrozen shrimp, you may only need to cook for 1 minute. I do recommend smaller potatoes in that instance.
A Family Friendly Meal
This Instant Pot Low Country Shrimp Boil is a fun meal that will get the family around the dinner table. There’s something for everyone!
Kids really like this Instant Pot Shrimp Boil. They get to eat with their hands, and you can include sausage that is not spicy for them. I like using kielbasa.
If you do like a spicy sausage, Andouille is very good in this recipe! Or use both kinds.

- 2 cups Water
- 1 1/2 Tbsp Old Bay Seasoning, divided (or use a good splash of Zatarain's® Concentrated Shrimp & Crab Boil liquid)
- 1 tsp Coarse Salt (or 1/2 tsp table salt)
- 1 lb New Potatoes, small, 4 oz size, or cut larger ones in quarters
- 1 Onion, cut in thick slices
- 6 cloves Garlic, roughly chopped
- 2 Bay Leaves
- 1 Lemon, quartered
- 2 tsp Cajun Seasoning, divided (optional)
- 2 ears Corn on the Cob, cut in thirds
- 1 lb Smoked Sausage, (cooked) cut in 2" pieces
- 2 lbs Shrimp, raw, large to jumbo size (easy peel, or split & deveined) partially frozen is best
- Butter, for dipping
- Crusty Bread
-
Have all of your potatoes, corn, sausage, onion, garlic & lemon chopped or cut before you start cooking. Also have the spices there with you as it will make this go faster/easier, and everything will cook at the proper times.
-
Add 2 cups of water to the pressure cooker and turn on the Sauté setting to get the water warming up.
-
Add the Old Bay seasoning (or shrimp boil seasoning), and salt.
-
Add Potatoes, onion, garlic, bay leaves, and lemon. Then sprinkle with some of the Cajun seasoning.
-
Add the Corn and sprinkle it with a little more of the Cajun seasoning.

Add the sausage.

Close the lid and set the steam release knob to the Sealing position, Then cancel the Sauté setting.
-
Press the Pressure Cook/Manual button or dial and then the + or - button or dial to select 2 minutes for frozen shrimp (1 minute for fresh shrimp). It will take several minutes to come up to pressure. Use High Pressure.
-
When the cook cycle is finished, turn the steam release knob to the Venting position and do a Quick Release of the steam/pressure. This will take a few minutes as the pot is full.
-
Open the lid once the pin has dropped down. Turn off the pot.
-
Use a spider skimmer or large slotted spoon to scoop the shrimp boil contents to a large bowl.
-
At this point you can dump it onto a table lined with newspaper or butcher paper, or put it on a baking sheet pan and serve it from there.
-
Melt some butter for dipping, and serve with some crusty bread.
TIP: If you keep the shells on the shrimp, and keep them partially frozen, they will not be overcooked.

We substituted beer for the water and it came out really tasty. We may add more garlic and spread some butter over everything before we serve as well.
This recipe looks amazing! Can you please tell me what brand/kind of Cajun Seasoning you used? Many thanks, Amy
Hi, thank you! I like Tony Chachere’s.
This was so good! I didn’t have a lemon so used a splash of lemon juice concentrate. Didn’t have a whole onion so used some frozen diced I had on hand and used frozen corn on the cob! Only 1lb of the shrimp fit in my IP, though…oh well! More for later! Thanks for sharing the recipe!
Made this for lunch and my wife just loved it! Very easy to make. Thanks!
I am assuming this is frozen RAW shrimp, deveined with shells on, correct? Excited to try this!
Yes it is!
Question: If I were to double the potatoes to 2 pounds and added 2 more ears of corn, would I need to increase the cook time?
Hi Kelly! As long as it fits in the pot, and they are the same size, you can keep the cook time the same.
I did use frozen, peeled, deveined tail-off raw shrimp (61-70 per lb., used the entire 16oz. bag) followed all your instructions but cut the pressure cooker off after 1 minute on high and transferred to a sheet pan in the oven on 200° to keep warm. I also don’t have that saute function, so I used 2 cups of hot water and hoped for the best! It turned out perfectly, my family isn’t even big on seafood- but they loved it with a pot of rice. The only things that were like mush were the lemons, so I’d say it’s a win ?
That’s awesome! That was so clever of you to do a shorter cook time so you could keep it warm in the oven! Thank you for your review!
I’m wandering if I could a peeled and deveined shrimp for this. Or do you have to use a shelled shrimp.
It’s all about the cook time. The size of the shrimp, and having the shell on, as well as being partially frozen, helps slow down the cook time so they don’t overcook. I would say if they are large, and frozen, you stand a better chance when they are already peeled.
This recipe was an instant success in our house. Delicious. I have shared it with my friends and family. Thank you.
That’s awesome, Windy! Thank you for your review!
We made this tonight since I had 2 lbs of wild caught gulf shrimp and shrimp boil concentrate begging to be used. We followed this recipe to a T. It was AMAZING. I am from Lousiana, so I’m hard to please with shrimp boils. It did take a good 20min to come to pressure, but it was well worth the wait.
Thank you, Katie! That’s quite a compliment from a Louisiana girl!
For the dipping sauce: is it butter or the juice from the IP?
Hi Anne, it’s the juice, or “pot likker” from the IP. You can also use butter, which is great on the corn!
One more question…I am making the Shrimp Boil this weekend for guests. My hubby bought Red Argentinian Shrimp even though I told him not to. They are not the Trader Joes RAS, and are much larger. The reason I said not to buy the RAS was because they cook so much faster than regular shrimp. So the question…since these shrimp are LARGE (16-20 per pound), and if I keep them frozen til I put them in the pot, can I keep the time at 3 minutes without worrying about them getting mushy? Thanks so much!!
Yes, if they are large, this time will work. I use the 21-25 and they are perfect for me. If yours are not completely cooked, just put the lid back on (on Venting) and lit it sit a couple minutes and check it again.
Thanks, Sandy! Really looking forward to it.
OMG. The best ever. Wow. Thank you so much for this easy to follow, but phenomenally great recipe! I think we went heavy on the Cajun seasoning since we love spicy and heat. This turned an average Tuesday into something very special. Thank you!!
Hi Karen! Yay! I’m so happy to hear how much you liked this shrimp boil! No more boring Tuesdays!
This sounds so yummy but I don’t have a pressure cooker. How can this be made without one?? Thank you
Hi Jan, I would layer the ingredients in a bit pot, except for the shrimp. Cook until the potatoes are done, then turn off the heat and add the shrimp on top and close the lid and let them steam until done.
Just wondering what size IP is good for this recipe? I don’t see that mentioned anywhere. Thanks!
Use a 6 quart or an 8 quart.
Loved this! I made my own Cajun seasoning otherwise followed the exact recipe. Some shrimp turned out little mushy (used frozen) might go for extra jumbo next time. I used jumbo 21-25 count
Hi Megan, I’m glad you liked this recipe! I think I also use the 21-50 count shrimp. Always with the shells. You might try cutting 1 minute off of the cook time and see if that helps. Of course, larger shrimp are a great solution as well! Yum! Thank you for your review!
I’m making it for dinner tonight. I know we’ll love it and am so happy to have an easy IP recipe. Thanks.
Wow! So delicious and really easy! Nice adaptation for the instant pot.
Thanks Kathy! I’m glad you liked it! It’s so nice to have something so easy and tasty!
We loved this recipe! I had never had a shrimp boil before so didn’t know what to expect. It was so delicious! My family had so much fun eating with our hands, and the kids laughed when I dumped it out on to the table. We will be having this with company next time. Thank you for sharing this great recipe!
Hi Cherish (I love your name!), I’m so glad you liked this shrimp boil recipe! I am going to make it for my kids when they come to visit! Thanks for your review!
