Loaded with tender clams, vegetables, and cream broth, this keto clam chowder is a hearty and rich meal you will quickly fall in love with. This low carb clam chowder recipe comes with a twist: we’ve given it a keto makeover, requiring no potatoes! In place of the potatoes, you have an option of using a daikon radish, which is the “keto potato”. It looks like a potato and has a similar texture.

This keto seafood soup is easy to make and doesn’t require any fancy ingredients. You will find everything in your pantry – no last-minute drive to the grocery store, as long as you always keep a can of clams in your cupboard.

If you try this keto clam chowder recipe once, you will never be tempted to cheat with the store-bought clammed seafood chowder again. The best thing about this delicious soup is that it is keto, low-carb and gluten-free. We use a keto friendly thickener called arrowroot powder.

The tenderness of celery and onion along with the creaminess of chicken broth and whipping cream will melt in your mouth. A burst of delicious flavors will explode on your taste buds. The slight brininess and underlying creaminess with the tenderness of the clams is the perfect thing. And if you add some daikon radish, the high carb potatoes will not be missed! The reds, greens and whites of this delicious soup make for an Instagram-perfect picture.

Top this creamy soup with crispy bacon and serve with a fresh batch of keto rolls.

Is Clam Chowder Keto?

As it is traditionally made, clam chowder is not keto. You will find this soup to be full of carbs from the flour (used as a thickener) and potatoes. But not anymore! With our keto clam chowder recipe, we have taken out the carbs while still maintaining the heartiness of this soup. This low carb chowder recipe replaces the high carb potatoes with low carb ingredients, including daikon radish – which acts like a potato in this recipe. If you can’t get a hold of a daikon radish, just omit it. You could try regular radishes if you wanted. One cup of daikon radish has 2.9 grams net carbs.

What is New England Clam Chowder?

Normally, New England clam chowders have clams, celery, onions, flour, cream and potatoes. Some recipes also call for salted pork. To replace the flour, we use arrowroot powder which is a keto friendly thickener for soup. To replace the potatoes, we use daikon radish, but you can omit that all together too. Some people will use celery root to replace the potato in keto chowder. You can use celery root as well if you grocery store carries it. Another popular vegetable in keto clam chowder is cauliflower. Cauliflower can also replace the potato in this chowder soup.

This keto soup recipe does have carrot for color and flavor. We only use 1/4 cup of carrots for the entire soup, so they don’t add too many carbs overall.

How Many Carbs Are in Clams?

For a 100 gram (3.5 ounces) clams serving, there are only 5 grams of carbs. One 6.5 oz can of clams has 8 grams total carbs. This keto seafood recipe features low carb vegetables so the soup will decrease our carb count that way. Clams are high in protein. Furthermore, they are also a rich source of vitamins, minerals and omega-3 fatty acids. Imagine enjoying a hearty, warm soup on a cold winter evening without counting the carbs in each spoon! Amazing, right?

How to Thicken Low Carb Seafood Soup?

Arrowroot flour is used to thicken most low carb soups. Once you have prepared the soup, add the arrowroot powder. Heat the soup at a low temperature so that it doesn’t form clumps. It is odorless and has a neutral flavor, making it the perfect option as a thickener. The best thing about arrowroot powder is that it also freezes well. So, you can make this keto chowder soup ahead and store it in the freezer and enjoy it the next day as well.

For extra creamy clam chowder, consider adding some cream cheese to your soup.
