Ingredients

Here’s what you’ll need to gather for this vibrant purple shrimp bisque recipe. Precise measurements ensure the perfect balance of flavor and texture.

For the Shrimp & Stock:

1 lb medium-large shrimp (about 16-25 count), shell-on, preferably wild-caught (You’ll use the meat later and shells for stock)
1 tbsp olive oil
1 medium yellow onion, roughly chopped (no need to peel for stock)
1 large carrot, roughly chopped (Or use 2 medium carrots)
2 stalks celery, roughly chopped
2-3 cloves garlic, smashed (no need to peel for stock)
1 bay leaf
1 sprig fresh thyme (or 1/4 tsp dried)
1/4 tsp black peppercorns
7-8 cups water (adjust as needed for desired stock quantity)
Salt to taste

For the Bisque:

4 tbsp unsalted butter, divided (Use 1 tbsp for cooking shrimp, 3 tbsp for bisque base)
1 tbsp olive oil
1 medium yellow onion, finely diced
1 stalk celery, finely diced
1 medium carrot, finely diced
1 medium purple potato (about 4-5 oz), peeled and finely diced (this provides the color!)
1-2 cloves garlic, minced
1/8 tsp cayenne pepper (or more, to taste)
1/2 tsp paprika
1/2 tsp Creole seasoning (optional, for extra flavor)
1/4 tsp white pepper (recommended for appearance)
3 tbsp tomato paste
1/3 cup all-purpose flour
Approx. 5-6 cups prepared Shrimp Stock (from above, amount depends on desired consistency)
1 tbsp white wine vinegar (optional, for a touch of acidity)
1 cup heavy cream
1-2 tsp fresh lemon juice
Salt to taste

For Garnish (Optional):

Cooked shrimp meat (reserved from peeling)
Drizzle of heavy cream or dollop of crème fraîche
Finely chopped fresh chives or parsley

Step-by-Step Instructions

Follow these steps carefully to create your delicious purple shrimp bisque recipe.

1. Prepare the Shrimp and Start the Stock:

Peel the shrimp, placing the shells in one bowl and the shrimp meat in another. Devein the shrimp meat if necessary. Cover the shrimp meat and refrigerate until needed.
Heat 1 tbsp olive oil in a large stockpot or Dutch oven over medium-high heat.
Add the reserved shrimp shells and cook, stirring constantly, until they turn bright pink and fragrant, about 2-3 minutes. Don’t let them burn.
Add the roughly chopped onion, carrot, celery, smashed garlic, bay leaf, thyme sprig, and black peppercorns to the pot with the shells.
Sauté for 5-7 minutes, stirring occasionally, until the vegetables begin to soften slightly.
Pour in the 7-8 cups of water (using slightly more water ensures enough stock for the recipe). Bring the mixture to a boil, then reduce the heat to low, cover, and simmer gently for 20-30 minutes to extract maximum flavor. Skim off any foam that rises to the surface.

2. Make the Bisque Base:

While the stock simmers, melt 3 tbsp butter with 1 tbsp olive oil in a separate large, heavy-bottomed pot or Dutch oven over medium heat.
Add the finely diced yellow onion, celery, carrot, and purple potato.
Season with a pinch of salt and the white pepper. Cook, stirring frequently, until the vegetables are softened but not browned, about 8-10 minutes. The purple potato should be tenderizing.
Stir in the minced garlic, cayenne pepper, paprika, and optional Creole seasoning. Cook for 1 minute more until fragrant.
Add the tomato paste and cook, stirring constantly, for 1-2 minutes until it darkens slightly in color. This deepens the flavor.
Sprinkle the flour over the vegetables and stir continuously for about 1-2 minutes to cook out the raw flour taste and coat the vegetables evenly. This forms the roux that will thicken the bisque.

3. Combine and Simmer:

Strain the shrimp stock through a fine-mesh sieve into a large bowl or another pot, pressing gently on the solids (shells and vegetables) with the back of a ladle to extract all the liquid. Discard the solids. You should have around 5-6 cups of flavorful stock.
Turn off the heat under the vegetable/roux mixture. Slowly whisk in about 1 1/3 cups of the prepared shrimp stock into the pot with the vegetables. Stir constantly to incorporate it smoothly into the roux and lift any bits from the bottom of the pot.
If using, stir in the optional 1 tbsp of white wine vinegar now for a hint of acidity.
Return the heat to medium-low. Gradually whisk the remaining hot shrimp stock into the pot.
Bring the soup to a gentle simmer. Reduce the heat to low, cover, and cook for about 15-20 minutes, stirring occasionally, to allow the flavors to meld and ensure the purple potatoes are very tender.

4. Blend the Bisque:

Remove the pot from the heat. If you used a thyme sprig, remove and discard it.
Carefully transfer the soup to a high-powered blender. Important: Blend in batches, filling the blender no more than halfway each time to avoid dangerous pressure buildup from the hot liquid. Hold the lid down firmly with a kitchen towel while blending. Alternatively, use an immersion (stick) blender directly in the pot.
Blend until the soup is completely smooth and velvety. The purple potatoes should blend in, giving the bisque its signature color. This may take a couple of minutes per batch.

5. Strain and Finish:

For an extra-smooth, restaurant-quality texture, place a fine-mesh strainer over another clean pot or the pot you initially cooked the bisque base in. Pour the blended soup through the strainer, using a spatula or ladle to push the liquid through. Discard any solids left in the strainer.
Return the strained bisque to the stove over low heat.
Stir in the heavy cream and fresh lemon juice. Do not boil after adding the cream, just heat it through gently.
Taste the bisque and adjust seasoning with salt and more white pepper or cayenne if needed.

6. Cook Shrimp and Serve:

While the bisque is gently heating, prepare the reserved shrimp meat. You can either:
- Sauté: Melt the remaining 1 tbsp of butter in a small skillet over medium heat. Add the peeled shrimp, season lightly with salt or Creole seasoning, and cook for 1-2 minutes per side, just until pink and opaque. Don’t overcook.
- Poach: Add the raw peeled shrimp directly to the gently simmering bisque and cook for 2-3 minutes until pink and cooked through.
Ladle the hot purple shrimp bisque recipe into warm bowls.
Garnish with the cooked shrimp (either whole or chopped), a swirl of extra heavy cream or crème fraîche, and a sprinkle of fresh chives or parsley, if desired. Serve immediately.

Serving Suggestions

This vibrant purple shrimp bisque recipe is elegant on its own, but pairing it with the right accompaniments elevates the experience:

Crusty Bread: Absolutely essential for soaking up every last drop! Offer slices of warm baguette, sourdough, or a rustic country loaf. Garlic bread or cheesy toast points are also fantastic choices.
Simple Green Salad: A light salad with a bright vinaigrette provides a fresh contrast to the rich bisque. Think mixed greens, cucumber, and a lemon-based dressing.
Oyster Crackers or Croutons: For a bit of crunch, sprinkle some classic oyster crackers or homemade garlic croutons on top just before serving.
Beverage Pairing: Serve with sparkling water with lemon or lime, or a crisp sparkling grape juice alongside the meal.
As Part of a Larger Meal: Serve smaller portions in cups or small bowls as an elegant appetizer for a multi-course dinner. It pairs wonderfully with grilled fish, scallops, or even a simple steak.
Presentation: Use shallow, wide bowls to best showcase the beautiful color and allow ample space for garnishes like the sautéed shrimp, a cream swirl, and fresh herbs.

Frequently Asked Questions (FAQs)

What makes this shrimp bisque purple?
The unique color comes from adding finely diced purple potatoes to the bisque base. They blend smoothly into the soup, imparting their natural hue without significantly altering the classic bisque flavor, perhaps adding a subtle earthy sweetness.
Does this recipe contain alcohol?
No, this version uses extra shrimp stock and an optional touch of white wine vinegar instead of the traditional wine or brandy.
Can I use frozen shrimp?
Yes, frozen shrimp work well. Ensure they are completely thawed before you begin, especially before peeling and using the shells for stock. Pat them dry after thawing.
Can I use pre-cooked shrimp?
You can, but the flavor won’t be quite as deep since you won’t have shells for the stock. If using cooked shrimp, skip the shell stock step (use good quality store-bought seafood or vegetable broth instead) and simply add the chopped cooked shrimp to the finished bisque to heat through just before serving.
Can I make this recipe ahead of time?
Yes, this bisque reheats well. Prepare the bisque completely (without adding the final shrimp garnish if sautéing separately). Let it cool, then store it in an airtight container in the refrigerator for up to 2-3 days. Reheat gently over low heat, stirring occasionally. Do not boil. Add freshly cooked shrimp just before serving.
Is this bisque spicy?
This recipe has a very mild warmth from the cayenne pepper. You can easily adjust the amount of cayenne to your preference – increase it for more kick or omit it entirely for no spice.
How can I make the bisque thicker or thinner?
If your bisque is too thick, whisk in a little more warm stock or water until it reaches your desired consistency. If it’s too thin, you can simmer it gently (before adding the final cream and shrimp) to reduce and thicken it further. Alternatively, make a small slurry of cornstarch and cold water, then whisk it into the simmering bisque until thickened.
Do I really need to strain the bisque?
Straining is highly recommended for the smoothest, most luxurious texture, especially since blended shrimp shells (even small bits) and vegetable fibers can remain. However, if you have a very powerful blender and don’t mind a slightly more rustic texture, you could skip the final straining step.

Recipe Tips for Success

Make your purple shrimp bisque recipe even better with these helpful tips:

Don’t Skip the Shell Stock: Using the shrimp shells is crucial for developing a deep, authentic seafood flavor base. It makes a world of difference compared to using just water or generic broth. Make extra stock as indicated in the recipe.
Sweat, Don’t Brown (the Base Veggies): Cook the finely diced onion, celery, carrot, and purple potato gently over medium heat until they are soft and translucent, but not browned (caramelized). This ensures their sweet, aromatic flavors meld into the bisque without overpowering it.
Cook the Tomato Paste: Stirring the tomato paste into the vegetables and cooking it for a minute or two helps concentrate its flavor and removes any raw taste.
Use White Pepper: For a visually pristine, creamy bisque without black specks, opt for white pepper instead of black pepper in the main soup base.
Blend Safely and Thoroughly: Hot liquids expand in a blender! Blend in small batches, never fill more than halfway, and hold the lid securely. Blend until very smooth for the best texture.
Strain for Silkiness: Don’t underestimate the power of straining the blended soup through a fine-mesh sieve. It removes any lingering fibrous bits from the vegetables or shells, resulting in an incredibly smooth, velvety texture.
Consider Vinegar for Acidity: A tiny splash of white wine vinegar (added with the stock) can help brighten the flavors. Lemon juice at the end also helps achieve this.
Temper the Cream: While not strictly necessary if you add it off-heat or over very low heat, you can temper the cream to prevent any possibility of curdling. Whisk a ladleful of the hot bisque into the cream in a separate bowl, then slowly stir the warmed cream mixture back into the pot.
Don’t Overcook the Shrimp: Shrimp cook very quickly! Whether sautéing separately or poaching in the bisque, cook them just until they turn pink and opaque (about 2-3 minutes). Overcooked shrimp become rubbery.
Taste and Adjust: Seasoning is key. Taste the finished bisque after adding the cream and lemon juice, then adjust salt and pepper as needed before serving. Lemon juice brightens the flavors.
Ingredient Quality Matters: Use fresh aromatics and good quality shrimp, as their flavors are prominent in the final dish.
