Steamed Seafood in the Instant Pot

Posted by Andrea on Jun 11, 2021

My love for my Instant Pot runs deep. I use it for basic functions like making soups, cooking dried beans quickly, hard-boiling eggs, cooking pasta, making the perfect cheesecake, braising meat and poultry, but I also do more nuanced tasks like making yogurt and cheese in it. 

So when my mom brought me a magazine article from a chef in Louisiana who steams oysters in the Instant Pot, I ran to my local seafood shop for fresh oysters to give them a try. What resulted is a slight obsession with steaming seafood in the multi-cooker, which could not be easier. 

oysters 4 waysThe beauty of the Instant Pot is that it's an all-in-one machine. You can sauté, steam, pressure cook, ferment, and if you are a true gadget nerd like me, you have a CrispLid that transforms the Instant Pot into an air fryer (note: newer models of the Instant Pot have an air fryer function, mine is just OG). 

For my steamed seafood study, I used oysters, clams and mussels. I'll break down each bivalve mollusk and provide a simple formula that you simply can't forget.

I love chargrilled and baked oysters, but I will admit that shucking oysters is not my favorite kitchen task so I rarely make them at home. But if you steam them, the shucking is done for you! All you have to do is put the oysters in the Instant Pot with a little water, steam for a couple of minutes, quick release and the shells practically open on their own. I used my oyster knife for a couple of oysters, but most opened very easily by just pulling the shell apart with my fingers.

Close and lock the lid. Select steam function and set timer for 2 minutes. It will take about 15 minutes for the pressure to build so while that's happening, melt 6 Tablespoons butter, and add 2 Tablespoons Tabasco sauce (or your hot sauce of choice), 1 clove garlic minced and 2 Tablespoons fresh chopped parsley and stir until combined.

oysters and shrimpOnce I saw how quick and easy steaming oysters was in the Instant Pot, I started experimenting with different toppings. Next on the menu was oysters four ways with toppings consisting of:

  • Cajun Garlic Butter (same as above except I omitted the parsley since I used it in the below breadcrumb mixture)

cajun garlic butter

  • Classic Mignonette (red wine vinegar and minced shallot, typically served with raw oysters but also delicious on steamed ones)


  • White Wine Cream Sauce (sauté shallot in butter, add white wine, reduce and add heavy cream and reduce again)

  • Toasted Panko Breadcrumbs with Grated Parmesan Cheese and Parsley

breadcrumb toppingAll of the toppings were good, but when I combined the Cajun garlic butter with the breadcrumb mixture, we had a clear winner!

Steamed Clams

When purchasing fresh clams or any seafood, they should come with a label so you know where and when they were harvested. I was lucky enough to get Cedar Key clams from Florida.

raw clamsI utilized the sauté function of the Instant Pot to make a white wine sauce to steam the clams in, but the rule of steaming for two minutes still applies.

Steamed Mussels

Next up were mussels. Give your mussels a good rinse and discard any that are open or have broken shells.

open musselsMost of my mussels were already "cleaned" which means the beard has been removed, but I found a few stragglers. Just pull those hair-like fibers out of the mussel.

So I thought I'd try to recreate those recipes as close as possible using my Instant Pot and CrispLid. Again, it's the same formula: steam for 2 minutes. This time, I made a sauce with rosé hard cider and shallot. The Hopleaf uses Wittekerke beer, but I couldn't find that and had a can of the cider in my pantry so I went with that. 

rose ciderI sautéed some shallot in butter, added the cider and then the mussels. Steam for 2 minutes and quick release (notice a very easy-to-remember pattern here?).

musselsOnce again, serve with lots of crusty bread to sop up that sauce and some fries made with the CrispLid (or any air fryer) with a garlic aioli for dipping and glass of rosé for sippin'.
