Crab soup is a cherished staple in many coastal cuisines, especially in places like Maryland where blue crab is plentiful. This rich, comforting soup highlights the sweet flavor of crab meat in a creamy, hearty broth. While recipes vary, crab soup is often thickened with a roux and accented with spices like Old Bay seasoning. It can be served as a first course or entree, and is especially popular during colder months when a warming bowl of soup really hits the spot.

A Brief History of Crab Soup

Crab soups originated where crab was abundant, which includes coastal regions of the United States and Asia. In America, crab soup has long been associated with Maryland cuisine. This is likely because the Chesapeake Bay has sustained large populations of blue crab for centuries. Fishermen would catch the tasty crustaceans and local cooks soon incorporated them into chowders and bisques.

Over time, recipes evolved to highlight the delicate flavor of the crab meat. Cream of crab soup emerged as a regional specialty, made rich and velvety with a roux and dairy. Splashes of dry sherry added complexity while Old Bay seasoning accented the brininess of the seafood It became a staple for Maryland crab houses and a must-try dish for visitors.

On the West Coast, Dungeness crab lends itself to hearty, tomato-based crab soups and stews And in Asia, you’ll find spicy crab soups featuring chili peppers and aromatics No matter the preparation, crab soup captures the essence of this sweet shellfish in soup form.

What Type of Crab is Best for Soup?

The most common types of crab used in soups are

  • Blue crab – This is the quintessential crab for Maryland-style crab soups. Blue crab has a delicate, slightly sweet flavor. The large chunks of jumbo lump crab meat shine when gently poached in cream soups.

  • Dungeness crab – Found off the Pacific coast, its sweet, briny flavor stands up to tomato broths and robust seasonings. The flaky meat adds hearty texture to West Coast-style crab stews.

  • King crab – The large legs offer bountiful meat with a very sweet, rich flavor. It works nicely in bisques but can be pricey.

  • Snow crab – Tender, flaky leg meat with a subtly sweet taste. Not used as often but can add variety to crab soups.

No matter what type of crab you choose, make sure it’s high-quality, fresh crab meat. Canned imitation crab doesn’t compare to the real thing when making crab soups from scratch.

Common Ingredients in Crab Soup Recipes

Dairy – Most crab soups start with a roux made from butter and flour. Milk or cream are added to create a creamy base. Half-and-half, heavy cream, or a mix of milk and cream are common. Avoid low-fat dairy options as they compromise the rich texture.

Vegetables – Onions, carrots, celery, and bell peppers help add flavor. Potatoes and corn lend starchiness and sweetness. Tomatoes are popular for West Coast-style crab stews.

Herbs & Spices – Old Bay seasoning is a must for Maryland crab soup. Other options include cayenne, paprika, thyme, sherry, Worcestershire sauce, lemon juice, and hot sauce. Basil, parsley, tarragon, and chives help finish the soup.

Seafood Stock – Adding shrimp shells, lobster shells, or fish bones contributes extra seafood flavor. Chicken stock also works nicely.

Crab Meat – Jumbo lump or backfin lump crab meat is ideal for maintaining large, tender chunks in the soup. Avoid canned crab meat which lacks flavor and texture.

By thoughtfully combining these supporting ingredients, you allow the natural sweetness of the crab to shine through.

The BEST Cream of Crab

I’m extremely particular about my cream of crab soup. It’s a favorite of mine and easy to find here in Maryland, but it’s too bad that so many places don’t follow the simple recipe. My recipe tackles some of my biggest pet peeves with this classic soup.

How to Make It

what is crab soup

  • Cook the onion in melted butter until softened.
  • For about 90 seconds, whisk in the flour, spices, and salt. Like blooming cocoa powder, letting the spices and flour cook this way makes them taste better.
  • While whisking, slowly add the half-and-half. Then, let the soup simmer until it gets thicker (be sure to stir it often!). When it coats the back of a spoon, it’s done.
  • Stir the crab meat, cream, and sherry together after adding them. Keep cooking on low heat for a few more minutes; the soup will keep getting thicker as it cooks. Then, enjoy!

SAM’S TIP: It’s very important to let your soup thicken enough after adding the half and half. It should coat the back of the spoon enough that you can’t see the spoon through the soup. Otherwise, it won’t be as thick as it ought to be.

You should enjoy this within 3 days of preparing. Make sure to store it in an airtight container in the fridge.

I say yes with a caveat. I personally don’t like to freeze it because, like my potato soup and many other cream-based soups, it tends to separate and get worse as it thaws. This can sometimes be remedied by reheating over low heat and whisking, though. If you don’t mind this and still want to freeze the soup, read the recipe notes below for full instructions on how to do so.

Because of the flour roux and the cream, this soup will be thick. But you need to let the heavy cream thicken before you add the crab meat and follow the rest of the recipe. There are pictures in the recipe to help you make sure your soup is at the right stage before you move on. The soup will also continue to thicken as it sits. If your soup is too thick, you can always add a little water or broth to thin it out.
