This Instant Pot Keto Clam Chowder is just like your favorite complete with a stellar potato substitute - turnips!

This recipe was so flavorful and delicious! Thank you so much! Even my  picky son liked it. I bought two cans of Bubble Bee whole baby clams and I had a lot of juice but to make up the difference I added chicken broth instead of water. Besides that, I followed the recipe just as it was and we all really liked it. Thanks again!


Christina, thank you for the lovely feedback!


I read through the recipe twice and don’t see instructions on when you’re supposed to add the clams. I know they can get rubbery if you cook them too long, so I don’t want to make any assumptions.


Hi Tanya, they are added after the pressure cooking (see step 4). I hope this helps!


This looks great! But is the nutritional information really only for a 1/4 cup?  


Hi Susi, it is per 1 1/4 cup. I hope this helps! 😊


This clam chowder is awesome! Delicious! Amazing! Five stars for you!!


Thank you Ingrid!


Omg this is delicious!! Added a few pieces of frozen haddock fillets too. My non Keto family loved it. I am not a fan of turnips but I found you couldn't taste them. Will definitely make this again.


Thank you Theressa! If you need to substitute, try rutabaga or cauliflower 😊


Made it on the stove top. Loved it! So delicious!  Added a little arrowroot powder to thicken. Next time will also buy a bottle of clam juice so i can use less water.


Thank you Jeanne!


How can you make this without an instant pot?


You can make it on the stove. It's the same steps as for the Sauté program, and then instead of pressure cooking, you'll need to cook it covered for a little longer (until the vegetables are tender).
