Key Ingredients
Crab Meat: This recipe uses jumbo lump crab meat, which you’ll add straight to the slow cooker. Fresh is best, but canned is acceptable if needed.
Cream, Milk & Butter: These add richness and a smooth, velvety texture to the soup.
Seasonings & Thickener: Classic seasoning like Old Bay brings signature flavor, along with salt and pepper.; cornstarch thickens the soup to the perfect consistency.
How to Make Cream of Crab Soup
- Add the main ingredients to your slow cooker.
- Let it cook low and slow until hot and well combined.
- Stir in a thickener to give it a creamy finish.
- Serve and garnish with crackers and a sprinkle of Old Bay.
Sarah’s Tips & Variations
- You can swap in clams for the crab, or use shrimp or scallops—just add those during the last 30 minutes of cooking.
- Celery, onion, and diced potatoes are great add-ins, but be sure to mince them small since this recipe doesn’t cook for very long.
- And don’t skip the Old Bay—it’s what gives this soup that classic Maryland-style flavor.
How to serve
- Toppings: If you have some crab left over, consider adding a few pieces on the top along with an extra dash of bay seasoning and a handful of oyster crackers.
- Side Dishes: You may not consider serving a side with this soup, but here are a few to consider: breadsticks, sourdough bread, or corn on the cob.

Hi, I have one question about the crab. Can you use can crab meat, if so how much is a pound in the cans?
Yes, you can use canned. Use 16 ounces (or however much you choose). It can be spendy.
Any idea how this might work with imitation crab meat, just out of curiosity?
I think imitation crab would work just fine!
Is this different from lobster bisque? Or just a simpler name?
Bisque has tomato in it, so a little different.
