Heat a Dutch oven or soup pot on medium heat and add the butter.
4 tablespoons unsalted butter
When melted, add the flour in stages in stir. You add it in stages to avoid clumping. This will create a roux.
4 tablespoons all-purpose flour
Add the celery, onions, and carrots to the roux and stir. Cook for 3-4 minutes or until the vegetables are soft.
½ cup chopped carrots, ½ cup chopped celery, ½ cup chopped onions
Add the garlic. Cook until the garlic is fragrant.
3 garlic cloves
Pour in the seafood stock, heavy cream, milk, Worcestershire sauce, hot sauce, Old Bay Seasoning, salt, and pepper to taste and stir. Stir until the ingredients are well combined.
2 cups Seafood Stock, 1 cup heavy whipping cream, 1 cup milk, 1 teaspoon Worcestershire sauce, ½ tablespoon hot sauce, 1 teaspoon Old Bay Seasoning, salt and pepper to taste
Use an immersion hand blender to puree and smooth out the soup. Alternatively, you can transfer the soup to a high powered blender. Be careful, it's hot.
Blend the soup until creamy and smooth. Add the crab meat to the pot. I like to add half of the crab meat here. Stir and cook for a few minutes until fully combined and warm.
1 pound lump crab meat
Serve the soup and top the servings with the additional remaining crab meat.
