I adore shrimp bisque and this recipe is from Ina Garten. It’s creamy, with a great shrimp flavor, as you use the shells as added flavor. Serve with warm crusty bread.
1lb large shrimp, peeled and deveined, but keep all the shells
4 cups seafood stock (for US cooks, this brand is available in markets)
3 tbsp good olive oil
2 cups chopped leeks, white and green parts (3 leeks)
1 tbsp chopped garlic (3 cloves)
pinch of cayenne pepper
1/4 cup Cognac or brandy
1/4 cup dry sherry
4 tbsp (1 stick) unsalted butter
1/4 cup all-purpose flour
2 cups half and half
1/3 cup tomato paste (puree)
2 tsp kosher salt
1 tsp freshly ground black pepper
Place the shrimp shells and seafood stock in a saucepan and simmer for 15 minutes. Strain and reserve the stock. add enough water to make 3 & 3/4 cups.
Meanwhile, heat the olive oil in a large pot or Dutch oven. Add the leeks and cook them for 10 minutes over medium-low heat, or until the leeks are tender but not browned. Add the garlic and cook 1 more minute.
Add the cayenne pepper and shrimp and cook over medium-low heat for 3 minutes, stirring occasionally. Add the Cognac/brandy and cook for 1 minute more, then the sherry and cook for 3 minutes longer.
Transfer the shrimp and leeks to a food processor fitted with a steel blade and process until coarsely pureed.
In the same pot, melt the butter. Add the flour and cook over medium-low heat for 1 minute stirring with a wooden spoon. Add the half and half and cook, stirring with a whisk, until thickened, about 3 minutes.
Stir in the pureed shrimp, the stock, tomato paste, salt and pepper and heat gently until hot but not boiling.
Season, to taste, and serve hot
