Shrimp and Sweet Potato Bisque

Ingredients
- 3 tbsp olive oil
- 2 pounds raw Gulf shrimp in shells
- 2 quarts water
- 1 pint dry white wine
- 8 ounces clam juice
- 2 bay leaves
- 1 shrimp bouillon cube
- 2 tbsp butter
- 1 cup chopped onion
- 1/2 cup diced celery
- 1/2 cup diced carrot
- 2 cloves minced garlic
- 1 10 oz can Rotel original diced tomatoes, drained
- 40 ounces Princella cut sweet potatoes, drained
- 1 1/2 cup frozen sweet corn, thawed
- 1 tsp dried thyme
- 2 tbsp paprika
- 1 1/2 tsp salt
- 1/4 tsp black pepper
- 3 ounces can tomato paste
- 1/4 tsp Worcestershire sauce
- 1/2 tsp Old Bay seasoning
- Tabasco sauce
- 3 tbsp butter
- 1 pint heavy cream
- Salt & black pepper
- Paprika for garnish
Step-by-Step Instructions
- Heat olive oil in a deep skillet over medium-high heat and sauté shrimp until shells are red and crisp, about 5-7 minutes. Remove from heat, cool, and peel. Reserve shells for seafood stock and refrigerate shrimp meat for later incorporation.
- In a large stock pot, combine water, dry white wine, clam juice, bay leaves, shrimp bouillon, and shrimp shells. Bring to a boil over high heat, then reduce heat to medium-low and let simmer for 30 minutes to develop a rich shrimp stock.
- While stock simmers, heat 2 tbsp butter in the skillet over medium heat and sauté onion, celery, carrots, and garlic. Cook until vegetables are wilted and softened, about 8-10 minutes, then add drained tomatoes, sweet potatoes, and corn. Cook another 5 minutes. Stir in thyme, paprika, salt, pepper, and tomato paste. Let simmer until reduced and thickened, about 5-7 minutes.
- Strain the shrimp shells from the stock and discard. Add the vegetable mixture to the stock pot. Bring to a boil, reduce heat and simmer for 30 minutes to blend flavors.
- When the soup is finished cooking, remove bay leaves. Working in batches, puree soup in a blender or food processor (solids first for easier blending), then strain through cheesecloth or fine mesh wire strainer back into the pot for a silky smooth texture. Left over solids may be saved and used in other recipes such as savory bread.
- In food processor, coarsely chop the reserved shrimp then add to the soup and simmer for 5 minutes until just cooked through. Season with Tabasco sauce to taste, Worcestershire, and Old Bay. Enrich the soup by whisking in the softened butter and heavy cream, then adjust seasoning with salt and pepper. Keep warm over low heat while flavors blend until ready to serve. Ladle into warm bowls and garnish with a shake of paprika.
Common Problems and Solutions
Q: Why does my bisque taste watery or bland?
A: Make sure you simmer the shrimp shells for the full 30 minutes to extract maximum flavor. Don't skip the step of reducing the vegetable mixture before adding to stock—this concentrates flavors. Also, season generously and adjust at the end after adding cream.
Q: Can I skip the straining step?
A: You can, but straining is what makes this a true bisque with that signature silky-smooth texture. If you skip it, you'll have more of a chunky soup, which is still tasty but not technically a bisque.
Q: Why did my bisque separate or look grainy?
A: Add the cream at the end over low heat and don't let the soup boil after adding cream, or it may break. Make sure the butter is softened when you whisk it in. If using a blender for hot liquid, work in small batches and vent the lid to prevent pressure buildup.
Tips and Techniques
Don’t overcook the shrimp when you add them back at the end—5 minutes is plenty since they’ve already been sautéed. For extra depth, you can roast the sweet potatoes before adding them instead of using canned. This freezes beautifully for up to 3 months; just reheat gently and whisk to restore smooth texture.
Ingredient Substitutions

Equipment Needed

Historical Context
Bisques originated in French cooking but were embraced by Louisiana Creole cuisine, which has a strong French influence. The addition of Louisiana sweet potatoes makes this a distinctly regional variation, showcasing the state’s agricultural heritage alongside its famous Gulf seafood.
