Instant Pot /Pressure Cooker Low Carb Manhattan Clam Chowder, a delicious Keto and Weight Watchers Friendly, Gluten Free, Low Calorie restaurant quality soup
That’s not Potatoes you see in the photo!!!!
Nope, this Pressure Cooker Low Carb Manhattan Clam Chowder is totally Low Carb, Gluten Free, Weight Watchers Approved, Low Calorie and it tastes delicious.
Seriously, this is the best Manhattan Clam Chowder I have ever had.
The best part? Well, it is super easy to make in a Pressure Cooker.
My Manhattan Clam Chowder is probably different from what you are used to getting at a restaurant or in a can.
I’ve made it super healthy and super delicious. Turnips and Radish replace the Potatoes.
Trust me, you will NOT miss the Potatoes. Have you tried my Pressure Cooker Ameriana Wedding Soup?
How about my Low Carb Air Fryer Hash Brown Radishes?

What Vegetables are in Low Carb Manhattan Clam Chowder?
- Red Pepper
While your Instant Pot or Pressure Cooker is heating, chop up the vegetables.
Most of the vegetables are diced to about the same size. The celery should be finely diced.
It is always important when using a Stainless Steel cooking pot to wait for the pot to heat up completely before adding a fat. Doing so will make the cooking pot, non stick..
Leave the Bacon alone and let it render.
Depending on how fatty the Bacon is, will determine if you will need to dump out some of the fat.
When the Bacon begins to turn brown, use a High Temperature Spatula and scrape the brown bits from the bottom.
If you use regular Bacon, it will render quickly.
Thicker Bacon, like in the photo, will take a bit longer.
I forgot to take a photo of when I added the Celery, Carrots, Red Pepper and Leaks.
I wanted to show you the discoloration on the bottom of the cooking pot from cooking the Bacon.
As the Vegetables begin to soften, they will release water.
Once that happens, it very easy to use your High Temperature Spatula and scrape the bottom of the pot and deglaze it, so that nothing is stuck and the pot returns to it’s clean and shiny state.
What Seasonings are in Manhattan Clam Chowder?
Well, my version is different than any version I have seen.
So, these are some of the seasonings that I use. Remember, the veggies also add a particular flavor.
Once the Veggies are beginning to soften, add in all the Seasonings.
As you Sauté the Minced Garlic with the Seasonings, the liquid will start to evaporate.
You’ll smell the yummy Garlic, in about about a minute. The veggies will now have a syrupy texture to them and look delicious.
Pour in the all the Clam Juice from the Cans of Chopped Clams. There will be about eight ounces of yummy Juice. You’ll need about 16 more ounces of Clam Juice. It is sold in bottles.
If you cannot find bottled Clam Juice, you can use Better than Bouillon Clam Base, mixed with Fresh Water to equal 16 ounces.
The Diced Tomatoes add nice texture to the Manhattan Clam Chowder.
The Crushed Tomatoes will break a part and add to the thickness of the Chowder. If you want a less tomato-y Chowder, just use more Diced Tomatoes instead of Crushed. Tomato Paste adds a deeper flavor to the Soup.
In the case of canned Tomatoes, brand does matter, so get the best brand that you can afford.
A great substitute for Potatoes in Soup are Turnips and Radishes.
It may sound weird, but I promise you that when you cook Radish, it loses the bitter and spicy taste.
Radishes kind of takes on the taste of whatever you are cooking.
In this moist environment, they will be the texture of a parsnip/carrot, but without the starch.
The Turnips taste sort of like ‘clean’ Potatoes. Smoother, but not mushy.
If you want to use only Turnips and no Radish, it’s fine. Just dice up the whole Turnip in that case.
I am so exited for you to try this Pressure Cooker Low Carb Manhattan Clam Chowder.
It’s one of those soups, where the Potatoes are really quite key.
So, this Low Carb, Low Calorie version will be such a treat.
For another Seafood recipe, try my Pressure Cooker Seafood Corn Chowder.
Chopped Clams are what used.
I you want to throw in fresh Clams too, that is great and will add a nice flavor.
Add them in after Pressure Release and Simmer, until the Shells open.
I added both, but wrote the recipe for Canned Chopped Clams, since they are so easy to source.
Tons of good veggies and Clams in this Chowder.

Pin it Pressure Cooker Low Carb Manhattan Clam Chowder
I loved your recipe. However there is a mistake in your directions. You say to put the leeks, turnips and radishes in one bowl. But then the leeks are to be sautéed with the carrots and pepper. I had trouble separating the leeks from the turnips and radishes so they could be sautéed. Other than that, it is a great recipe!
This soup was awesome! I I initially had my doubts because of the turnips and radishes (which I have never used isn’t 40-plus years of cooking). But the radishes blended in nicely and my husband did not realize I had used turnips rather than potatoes. I did not have the chili paste so I used red pepper. This recipe is a keeper!
I want to try to make this soup, how many carbs per serving and how many servings? Thank you

Hi Danny. I added that info to the recipe card. Hope it helps and enjoy! Jill
Barbara Mays-Stock says
This recipe looks fantastic and I want to make it this week. Very important question, though. It’s just my husband and me, so can this Chowder be frozen and still maintain its yummy taste and “mouth feel?”
Thanks for another great recipe! I put it out on my Face Book just now!
Jill Selkowitz says
Yes, you can freeze. Jill
I almost cried when I tasted this. It’s that good!! Thank you, Jill!!

Donna P. says
Thanks for sharing! I made this for dinner tonight and fooled my husband with the turnips. The chowder was delicious!
I am so glad this was a hit! Jill
Lori J Chapman says
A question, have you tried this using just turnip but no radish? Thanks!
Simply superb!! I chose to omit potatoes as well as their substitutes – radishes and turnips.
I am so glad you enjoyed this recipe, Dana. Jill
Kathy Parakin says
My husband raved about this soup.
Virginia stecker says
How many people does the clam chowder serve?
Probably six people. Jill
Question: In the beginning of your photo step-by-step description above, you mention the seasonings you like to use in this recipe, one of which, Sea Salt. However, in the actual recipe, Sea Salt is not listed…actually, no salt is listed. Is this a mistake? If so, how much Sea Salt is needed for this recipe. Making it tonight cuz Manhattan Clam Chowder is my FAV!!!
Donna, thank you for noticing. I have just added it. Enjoy. Jill
Reba Scott says
This looks wonderful…..cannot wait to try it. We just started a low card meal plan so this sounds perfect! While I’ve got most of the ingredients I don’t have any turnips or radishes, cooked radishes was such an alien idea to me and sounded awful, but you make them sound awesome so I’m game!! What can I substitute for the Sambal Oelek Chili Paste, cause I’m pretty sure I won’t be able to find it? I won’t get to the store before next weekend because right now I can’t even see the road in front of the house!! Snow!! Thanks for the recipe and any help!!
Pepper flakes. Jill
This looks delicious, and I don’t even like clams, ha ha. I will be making this for my husband, though, who loves clam chowder. The bonus is it’s low-carb, which is how I eat, so I can have some too. Can’t wait to try it!
I am excited to hear how you both like this, WG. Jill
