Crab bisque is the elegant cousin of chowder with a smoother, richer, silkier, and deeply flavored with seafood essence. Where chowder is chunky and rustic, bisque is refined and velvety, often served as a first course in fine dining restaurants and coastal kitchens. Today we’re making it at home step by step with video, expert tips and all you need to know!
Both our Lobster Bisque and this recipe are rooted in French culinary tradition. A bisque is traditionally made by extracting maximum flavor from shellfish shells, then blending and straining for a smooth, luxurious finish.
Today you’ll see crab bisque on lots of restaurants across the US and the world, especially in Maryland and other coastal places. And if you’ve wanted to make it at home, this is all you need to know.
We make our own Lobster Stock and Crab Stock for this recipe, and use freshly cooked crab meat from our guide on How To Cook Crab Legs.
So if you have any seafood shells, make sure to keep them sealed in a freezer bag to make some stock and luscious bisques for another day.
What Is Crab Bisque?
Crab bisque is a smooth, creamy soup made from crab meat, aromatics, a rich shellfish stock (we used our Crab Stock) and is always finished with cream and bright herbs.
Unlike crab chowder, a bisque is fully blended and strained with a velvety texture and a rich taste.
Why You’ll Love Crab Bisque
- Deep Seafood Flavor: By using our homemade Crab Stock, you get an intense crab flavor.
- Ultra Smooth Texture: We strain the soup for extra silkiness and richness.
- Tasty! The aromatics, crab meat, stock, and finish with cream creates a tasty and delicious combo for a soup that feels like a hearty meal.
- Make Ahead Friendly: The flavor improves overnight, so it’s great for entertaining too!
- Restaurant Quality made easier and homemade: It’s the best way to make it at home from scratch using fresh ingredients where you have full control. We love adding fresh tomatoes instead of tomato paste for example, and by making it at home, we can control that.
Ingredients You’ll Need
- CrabMeat: Lump or claw meat, cooked fresh crab is best using our How To Cook Crab Legs.
- Crab Shells. If you didn’t have time to make the Crab Stock ahead of time, then you will be simmering the shells to intensify flavor.
- Seafood stock. We love our homemade Lobster Stock or Crab Stock, you can use store bought or, simply boil the crab shells. You can use vegetable stock if that’s all you have, chicken stock, fish stock or your favorite.
- Aromatic Base: Also known as Mirepoix, which is basically onions, celery, carrots, garlic. These create sweetness and the backbone flavor base to our bisque.
- Tomato. You can use paste or fresh tomatoes. We need just a small amount to add depth and subtle acidity.
- Herbs. We use fresh parsley, thyme, bay leaves.
- Butter. The base of the recipe, it builds richness to the bisque. While you can use olive oil or any oil, we prefer butter.
- Thickener Options: To thicken the bisque, a light roux is made using all purpose flour and butter. However, rice is the more traditional french way.
- Heavy cream: The creamy finish and velvety richness added at the end.
- Seasoning. A simple kosher salt and black pepper is best, some paprika ad granulated garlic, this recipe uses minimal spices so the crab can shine.
- Optional: If you can find clam juice, it adds so much flavor to the recipe. You can also replace some stock with dry white wine and finish with lemon juice.
How to Make Crab Bisque
Build the Base
- First step is to melt butter in a pot over medium heat, and add in the mirepoix. That’s the onions, celery and carrots.
- Don’t rush this process, you need to sauté them well until golden and translucent so the flavors can deepen before moving on the next step.
- Add the garlic and cook for just a minute, you don’t want to overcook the garlic because it can turn bitter.
Make The Roux
- At that point, you’re ready to thicken the base of the bisque by making a simple roux. Use equal parts butter and flour, we used 1 Tablespoon of each here.
- Cook down the flour in the butter until you feel that it’s slightly toasty and golden. This eliminated any raw flour flavor.
Deglaze And Add Stock
- When the flour is toasty, it’s time to deglaze the pot. We added fresh baby tomatoes along with our Crab Stock.
- We also added in our bay leaves, thyme sprigs and seasoning. Now you’re going to stir the bisque really well to make sure o bites of flour are on the pan surface. The liquid should deglaze the pot, but some bit may be stuck to the pan, so you need to scrape those using a wooden spoon.
- If you don’t have crab stock, you would need to add the crab shells at this stage and let them simmer gently with the tomatoes and fish stock.
- Simmer and cook the base of the bisque for 35-45 minutes.
Blend & Add Cream
- Use an immersion blender and blend the soup until smooth.
- Now pour the cream into the pot and keep the heat at a simmer.
- Strain the bisque for a smooth finish.
- Add in the crab meat last, and simmer some more.
- Season and adjust if needed.
