Crab Bisque Soup
by Sommer Collier — on Apr 1, 2026 My crab bisque soup is an elegant, restaurant-style dish that’s surprisingly easy to make at home. I use packaged lump crab meat, simple sautéed veggies, a light roux, and a splash of sherry, then blend it all into a rich, velvety soup with just the right amount of cream. This easy one-pot seafood bisque is cozy, bold, and full of flavor without being fussy.
Honestly, I’ll eat just about any seafood you put in front of me. Scallops, clams, fish across the spectrum of fishiness, lobsters, crabs… You get the idea. I love them all! Yet out of this list, I’d say my favorite is crab. It is upscale but accessible, like when I use it to make pan fried crab cakes, and not quite as expensive as some other types of seafood I mention.
In the spirit of making a decadent dish more casual (and on a slightly tighter budget), today I’m sharing with you my fabulous crab bisque soup recipe. This is a much simpler version of lobster bisque soup that’s still luxurious, but made with fewer ingredients and requires no cooking or shelling of seafood. All you need is a large pot and an immersion blender to make a rich bisque with big, bold seafood flavor and an ultra creamy, silky smooth texture in well under an hour!

Sommer’s Recipe Highlights
Well-Balanced Bisque – I always get rave reviews on this recipe for being decadent but not over-the-top… The sweet crab and the deeply sweet, almost nutty flavor of sherry are softened by heavy cream, while the bold tomato and zesty Cajun seasoning bring the soup back to the savory side. No one flavor overtakes the other, and instead, the crab bisque tastes equally, and perfectly, bright and rich.
Fancy without Fuss – This delightful soup is easy to make in one pot with ready-to-use precooked crab meat, from a container, and boxed seafood stock. Then you need only a handful of other kitchen pantry staples, plus sherry which you may or may not have on hand. (We usually keep a bottle of cooking sherry in the house… Or two.) I prepare it in only about 40 minutes from start to finish, and serve it right when it comes off the stove.
Main or a Side for All Occasions – Any gathering with a menu that includes “bisque” can be considered an elegant affair. I serve it at dinner parties as a lighter main dish, particularly during the summer months, or as a soup course before a main dish with a high-end protein. But truly, my crab bisque recipe is so straightforward and easy, don’t shy away from making it for casual dinners with the family!
Key Ingredients and Tips
- Veggies – I use chopped peeled onion and carrot (don’t bother peeling), plus several garlic cloves.
- Seafood stock – I prefer seafood stock made with a variety of shellfish versus fish stock for the deepest, umami flavor.
- Heavy cream – Please use real heavy cream for the most amazing soup texture. Seriously, the flavor and texture simply won’t be the same with any alternatives that contain less fat. This is a true bisque, and we’re not making diet food here, people!
- Crab meat – I use store-bought and ready-to-use shelled lump crab meat from a tub (or can) at the seafood counter. The tubs tend to be on the more expensive side, but the quality and flavor of the meat is typically better.
- Sherry – I use dry sherry (a little for the soup, a little for me). But cooking sherry also works well! It just has a more tart, lightly salty taste.
- Tomato paste – Just a couple of tablespoons is enough to add bright tomato flavor and help give the puree that gorgeous orange color.
- Cajun seasoning – I use this classic spice blend to season the soup in the true Southern fashion with a dash of heat. However, Old Bay is also delicious and adds more of a coastal, sweet, and herby flair to the crab soup.
How to Make

Prep and Sauté Veggies – I start by melting butter in my large soup pot over medium heat. Then I add the veggies and sauté for just a few minutes, until they get a bit of color on the outside.
Stir in Flour – Next, I sprinkle the flour evenly over the veggies. I continue to sauté everything for another 2-3 minutes, scraping the bottom of the pot to prevent the vegetables and flour from sticking or burning.
Deglaze and Simmer – The flour and butter will naturally create a slightly thick coating on the bottom of the pot. Once the flour is cooked, I pour in the sherry a splash at a time, while stirring and unsticking the veggies. Then I stir in the seafood stock to completely deglaze the pan, followed by the tomato paste and seasoning blend.
I increase the heat a bit to bring the soup base to a simmer, then bring it back down a tad to keep it from fully boiling. I let it simmer for about 15 minutes, stirring and scraping the bottom of the pot every few minutes, until the liquid is thick (almost like a gravy) and the carrots are super soft.
Purée – Now, this is very important: Move the pot off of the burner and turn off the heat. Then use your immersion blender to puree the soup and veggies until smooth. I don’t like to have any lumpiness in my bisque base, so usually it takes several minutes of blending, scraping down the pot with a spatula, and blending again until it reaches the perfect silky-smooth consistency.
Add Cream – I take that silky soup base to the next level of decadence by stirring in heavy cream. Then it becomes unbelievably thick, rich, and velvety… Now, it’s a true bisque!
Stir in Crab Meat – Here, I show adding the crab meat right into the pot. However, for a fancier presentation, you can ladle the bisque into bowls, then add a neat scoop of crab into the center of the bowl so it’s showing.
Expert Tips
An immersion blender is easiest to puree the vegetables and make a super smooth bisque base. But if you don’t have one, you can use a standard blender. Just be careful when adding hot liquid to a blender! Make sure to open the vent and cover it with a kitchen towel… If there’s no room for the steam to escape when you turn on the blender, the lid can come flying off creating a huge mess, not to mention burn you.
Serving Suggestions
Crab soup makes a fabulous light main dish. To add a bit more to the table, and be sure I sop up every single last drop of the soup, I serve it with warm French bread or homemade Red Lobster cheddar bay biscuits. (Yes, those biscuits!)
To balance the richness of the bisque, I also usually serve a fresh salad. Nothing fancy, a simple steakhouse-style salad or caesar salad with romaine hearts or any crisp, refreshing greens and dressing is great.
For more refined holiday dinner parties, I often serve surf-and-turf, and pair crab bisque with top-quality steaks. Reverse-seared filet mignon or classic French steak au poivre are elevated main proteins that don’t take much effort. But if you can’t get enough seafood (I don’t blame you) try pairing the soup with other seafood dishes like rich and cheesy seafood stuffed shells or scallop scampi, for the ultimate “surf and surf” meal.
Storing and Reheating
The soup really does have the most lovely taste and texture when it’s freshly prepared. However, should you find yourself with leftovers, they will keep well for 2-3 days in an airtight container stored in the refrigerator. And if you know you’ll have leftovers from the jump, I suggest storing the crab and soup separately.
Reheat the leftover soup very gently on the stovetop over low heat. Or microwave portions in short bursts at 50% power, just until heated through.
Frequently Asked Questions
Well yes, technically. But I don’t recommend it, or if you do, I don’t recommend trying to pass it off as a *true* crab bisque. That’s because imitation crab isn’t actually crab… Instead, it’s a combination of white fish that’s been chopped and shaped together. Tasty? Yes. Crab? No.
A dry white wine, like Pinot Grigio or Sauvignon Blanc, or sweeter brandy or cognac are great alternatives that offer a light, warm alcohol taste without overpowering the crab.
The alcohol evaporates quickly from the sherry when it is cooked, so don’t worry, kids are completely safe to eat crab bisque. But if you want a nonalcoholic substitute, you can easily use a bit more seafood broth or chicken broth.
Honestly, a bisque should not be “thick.” Yes, it needs to have some body so it flows beautifully and coats the spoon, but I’m not making a chowder here. If you feel you absolutely need to make it a smidge thicker, whisk together a slurry using 1 tablespoon of cold water with 1 tablespoon of cornstarch. Then slowly stir it in either right before or after adding the heavy cream, and allow it to simmer for a minute with the cream. Definitely do this before adding the crab! Otherwise, you’ll wind up overcooking the crab meat while the bisque simmers to thicken.

Ingredients
- 4 tablespoons butter
- 4 tablespoon all-purpose flour
- 1 cup chopped onion
- 1 cup chopped carrot
- 3-5 cloves garlic minced
- ¼ cup dry sherry or cooking sherry
- 32 ounces seafood stock
- 2 tablespoons tomato paste
- 1 tablespoon cajun seasoning
- 1 cup heavy cream
- 8 ounces lump crab meat drained
Instructions
- Set a large 6-8 quart pot over medium heat. Add the butter. Once melted, add in the chopped onion, carrots, and minced garlic. Stir and sauté the vegetables for 3-5 minutes, then stir in the flour. Cook the flour for another 2-3 minutes, scraping the bottom of the pot to make sure it doesn't stick.
- Then deglaze the bottom of the pot by pouring in the dry sherry. Stir and loosen any bits on the bottom. Add the seafood stock, tomato paste, and Cajun seasoning. Stir and bring to a simmer.
- Simmer the bisque base for 12-15 minutes stirring regularly. Once the base has thickened and the veggies are very soft, turn off the heat.
- Use an immersion blender to purée the soup base. Make sure it is very smooth. *If you do not have an immersion blender, you can carefully pour the soup base into a standard blender jar. Make sure to cover the blender jar, open the vent in the lid, and put a kitchen towel over the top. Turn the blender on low at first and then raise the speed to make sure it's well puréed. Be very careful when doing this, so you don't splatter hot soup all over yourself and your kitchen.
- Once the soup is puréed, turn the heat back on low and stir in the heavy cream. Simmer for another 2-3 minutes. Taste, then salt and pepper as needed.
- You can now stir in the lump crab meat. Or if you would like your crab bisque to look pretty in the bowls, ladle the hot soup into bowls and then scoop lump crab meat into a nice neat pile in the center before serving.
- Garnish with fresh chopped parsley, scallions, or even Parmesan cheese.
