Instant Pot Seafood Chowder is the ultimate seafood-lovers meal. Packed with whitefish, baby shrimp, crab meat, scallops and fresh lobster meat, this creamy chowder is delicious anytime of the year. It's a versatile chowder that can be made with your favorite seafood or as the recipe is written. It's one of our favorite chowders, along with pressure cooker Manhattan clam chowder and New England clam chowder.
While Instant Pot seafood chowder has a long list of ingredients, don't let that deter you. It's easy to make in 1 pot and in only 30 minutes. These ingredients are simply added to the pot and cooked, with little hands on work and minimal effort! It's practically a dump and start soup perfect for any pressure cooker skill level.
The great thing about Instant Pot seafood chowder is you can use a variety of crustaceans, finned fish, and mollusks. So if you don't have or don't like something I use here, simply replace it with something you do love.
As written, this recipe works in a 6, 8 or 10 quart pressure cooker. For 3 quart pressure cookers, you'll need to reduce the amount of servings.

Ingredients and Substitutions
The main ingredients in this Instant Pot seafood chowder are:
- Scallops: frozen work best so that they don't overcook. Use large bay scallops cut into pieces or whole small scallops.
- Lobster meat: if you can't find lobster meat, throw in some clams or mussels, or extra shrimp, crab or fish.
- Whitefish: I usually use tilapia but salmon, cod, and haddock are great options too. Use frozen so that it doesn't overcook and cut it into chunks before adding to the pot. Most of the fish will flake apart as it's cooked.
- Crab meat: make sure it's cooked, picked through, and in pieces. Always check for pieces of shells before adding to the pressure cooker. Like the shrimp, the crab is put in just at the end to warm.
- Shrimp: I use cooked baby shrimp so they can be put in at the end just to warm. Since uncooked shrimp take only a minute or two to pressure cook, this keeps them from overcooking.
- Clam juice: adds a nice seafood taste. Substitute with white wine or an extra cup of broth.
- Potatoes: waxy potatoes, like baby creamer potatoes, are best because they stay together in hot soups.
- Carrots, celery, onion and garlic
- Vegetable broth: use seafood stock or chicken broth as an alternative.
- Heavy cream: for a lighter version, whole milk can be used but the chowder will be a little less rich and creamy. Do not put whole milk under pressure, and instead add it at the end with the shrimp and crab.
- Thyme and parsley: I use dried but fresh can be used if you triple the amount.
- Old Bay seasoning: if you really enjoy this seasoning, you can use up to 1 teaspoon.
Feel free to use a different amount of each fish. Just make sure to keep the total quantity the same (3 pounds) so that you still end up with a hearty and chunky chowder.

Kristina's tips
Make The Best Seafood Chowder
- Make sure to do a controlled quick release to avoid frothy liquid from spraying out of the valve.
- If changing the type of seafood used, make sure to use the same total quantity so you still get a hearty, chunky chowder.
- If you'd like the broth thicker, melt 3 tablespoons of butter and mix with ¼ cup of flour. Set the finished chowder to saute for 2 minutes. Mix in the butter and flour paste and stir continuously until it begins to boil. Let boil for 2 minutes to thicken.
Instructions
- Set the Instant Pot to saute on normal (or high) for 3 minutes. Melt the butter and saute the carrots, onions, celery, and garlic stirring often.
- Pour in the vegetable broth and deglaze the bottom of the pan to ensure there are no pieces of stuck food. Add the heavy cream, clam juice, potatoes, frozen fish, frozen scallops, lobster chunks, thyme, parsley, Old Bay seasoning, bay leaves, salt, and pepper. Do not stir. *Heavy cream can go under pressure without curdling because it has a high fat content, which prevents it from doing so.
- Close and seal the pressure cooker lid. Set to pressure cook/manual on high for 5 minutes. Complete a controlled quick release of the pressure when finished.
- Remove the pressure cooker lid and stir in the baby shrimp and crab meat. Stir thoroughly and serve with oyster crackers, fresh herbs, and a dash of red pepper flakes if desired.

What Is A Controlled Quick Release?
To do a controlled quick release, lightly press or turn the pressure release valve so that the steam comes out slowly rather than at full force. You can stop for a few seconds and restart this manual pressure releasing method if liquid starts to spray out. A controlled quick release prevents hot frothy liquid from exploding all over your kitchen.
How To Store
Store uneaten fish chowder in the fridge for up to 5 days. I don't suggest freezing it, as the texture of the heavy cream will change.

Not bad, but a tad salty. Two teaspoons salt is too much. I would omit next time. I don’t keep heavy cream in the house so substituted with 1/2 & 1/2 or milk and melted butter, which can also add salt; store-bought broth can as well. I also don’t buy Old Bay but you can find a homemade recipe online. The one I found called for cardamom but used 1:1 nutmeg:allspice as substitute. Lastly, I added 1 tsp each dried dill and tarragon and garnished with crumbled bacon and fresh chives or green onions.
