Quick and easy keto creamy crab soup. Make with fresh crab or canned crab. A comforting, low-carb seafood bisque, ready in 15 minutes!
Can I have crab on the keto diet?
Is crab low carb and keto friendly? Yes. One can of crab meat has no carbs! That's right! None. Nada.
How do I make low carb creamy crab soup?
This low-carb and keto friendly crab bisque is easy to make.
First, you'll start with a roux-type of base for the soup. I like to use almond flour and butter to begin. In many traditional soups, you'll see a flour and butter base, but this one doesn't have all those nasty carbs!
Next, add in your dairy: half and half, cream cheese, and heavy whipping cream.
Finally, add in the crab and seasonings to the mix. I like to use dried chives, Old Bay Seasoning and Tony's Creole seasoning. If you don't have Tony's or chives, you may use fresh onions, onion powder, or garlic powder to substitute those ingredients. Just give it a little taste-test to determine your preferences of flavor.
Can I use canned crab to make crab soup/bisque?
I have to admit, I was really skeptical about using canned crab for this recipe. However, it was all I had on hand. To be perfectly honest, I wanted a fast crab soup that tasted like lobster bisque, but without all the fuss and long list of ingredients. This soup is simple, yet full of flavor, just like lobster bisque.

I loved this recipe ❤️ it was quick and easy for this momma of four!
Amazing and EASY!!! Thank you 🙂
Just finished a bowl and OMG, it was fantastic! This is the most simple recipe for such a great tasting soup. I had a container of lump crab that I was planning to make crab cakes with but came across this recipe and thought it seemed way to easy not to try it. This soup does not disappoint! It is noted that it makes 10 servings but I ate two ladles full as one serving so I am estimating this will be more like 5-6 servings. Thank you for the great recipe, I will definitely be making it again, an maybe even adding some extra seafood since it is nice and thick like a chowder.
Thank you so much for taking the time to try it out and stop by. I'm so glad you loved it <3!
Can I freeze this soup?
Hi Darlene,
because of the cream cheese, I do not recommend freezing. Thanks for stopping by!
Mine wasn't thick. Taste is great though
To thicken, you may add more crab or a bit of Xanthan gum.
All I can say is yummyyyyyyy!
