Celery Root Bisque With Sautéed Lobster

I’ll never forget the first time I tasted celery root. It was in a tiny, unassuming bistro in Paris, and I was expecting something assertively…celery-like. Instead, I was met with an earthy sweetness and a surprisingly delicate flavor. It was a revelation that changed my entire perspective on root vegetables. This Celery Root Bisque, elevated by the richness of sautéed lobster, takes that initial surprise and turns it into an unforgettable culinary experience.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 30 minutes
• Servings: 8-10
• Yield: 2 quarts
• Dietary Type: Gluten-Free (naturally)

Ingredients

• 1 tablespoon olive oil
• 1 cup diced onion
• 1/2 cup diced parsnips (or 1/2 cup diced carrot)
• 1/2 cup diced celery
• 1 tablespoon minced shallot
• 1 teaspoon minced garlic
• 4 cups peeled roughly chopped celery root
• 5 cups chicken stock
• 1 teaspoon salt
• 1/8 teaspoon cayenne pepper
• 1 cup cream
• 2 tablespoons chopped fresh parsley leaves
• 1 (2 lb) lobsters (or 2 frozen tails)
• 2 tablespoons unsalted butter
• 1 tablespoon minced shallot
• 1/2 teaspoon minced garlic
• 1/4 teaspoon salt
• 1 tablespoon lemon juice
• 1/4 cup chopped celery leaves

Equipment Needed

• 4-quart saucepan
• Immersion blender (or regular blender)
• Large (2-3 gallon) stockpot
• Cutting board
• Kitchen towel
• Mallet (optional)
• 10-inch saute pan

Instructions

1. Begin by preparing the bisque. Set a 4-quart saucepan over medium-high heat. Add the olive oil. Once hot, sauté the onions, parsnips (or carrots, if using), and celery until softened, approximately 4 to 5 minutes. Stir frequently to prevent burning.
2. Add the minced shallot and garlic to the pan and sauté until fragrant, about 45 to 60 seconds. Be careful not to burn the garlic; it should be aromatic, not bitter.
3. Introduce the celery root, chicken stock, salt, and cayenne pepper into the saucepan. Bring the mixture to a boil, then reduce the heat to a simmer. Cook until the celery root is tender, usually around 35 to 40 minutes. You should be able to easily pierce the root with a fork when it’s ready.
4. Once the celery root is tender, remove the saucepan from the heat. Carefully puree the soup using an immersion blender (or in batches using a regular blender), until completely smooth. For safety, when using a regular blender, only fill the container about halfway with hot liquid. Vent the lid and cover with a towel while blending.
5. Taste the bisque and adjust the seasoning if necessary. Add more salt or cayenne pepper to your liking. Stir in the cream.
6. Prepare the lobster. Set a large 2 to 3-gallon stockpot to boil over high heat. Once the water reaches a rolling boil, carefully immerse the lobster in the pot. Cook the lobsters for exactly 3 minutes. This partially cooks the lobster, making it easier to extract the meat without overcooking it.
7. Immediately remove the lobster from the boiling water and chill in an ice water bath. This stops the cooking process and helps the meat to firm up.
8. When the lobster is cool enough to handle, remove it from the ice water and place it on a kitchen towel draped over a cutting board. Use a mallet to crack the shells (or carefully use a knife or kitchen shears). Remove the meat from the tail, claws, and knuckles.
9. Dice the lobster meat into 1/2-inch pieces and set aside.
10. Set a 10-inch saute pan over medium heat and add the butter. Once the butter begins to foam, add the minced shallots and garlic. Sauté the shallots and garlic until fragrant, about 1 minute. Again, watch carefully to avoid burning.
11. Add the diced lobster meat to the pan and season with the salt. Sauté the lobster until cooked through, approximately 5 minutes. The lobster should be opaque and slightly firm to the touch.
12. Add the lemon juice and raise the heat to high. Cook for 2 minutes, allowing the lemon juice to deglaze the pan and create a light sauce.
13. Incorporate the chopped celery leaves to the lobster and toss to blend. Remove from the heat and set aside.
14. To serve, ladle the celery root bisque into bowls and top each bowl with approximately 3 tablespoons of the sautéed lobster. Garnish with chopped fresh parsley leaves.

Expert Tips & Tricks

• Make-Ahead Tip: The bisque itself can be made a day or two in advance. Store it in the refrigerator and reheat gently before serving. Do not add the cream until you are ready to serve.
• Celery Root Prep: Peeling celery root can be a bit tricky. Use a sturdy vegetable peeler or a paring knife to remove the tough outer skin.
• Lobster Cooking Times: If using lobster tails instead of whole lobsters, adjust the initial boiling time accordingly. Smaller tails will require less time. Aim for just undercooking them slightly, as they will continue to cook in the sauté pan.
• Vegan Variation: For a vegan version, substitute the chicken stock with vegetable stock and replace the cream with cashew cream or full-fat coconut milk. Omit the lobster altogether or replace it with sautéed mushrooms for an earthy flavor.
• Enhance Flavor: For a deeper, more complex flavor, roast the celery root before adding it to the soup. Toss the peeled and chopped root with olive oil, salt, and pepper, and roast at 400°F (200°C) for about 20-25 minutes, or until tender and slightly caramelized.

Serving & Storage Suggestions

This Celery Root Bisque with Sautéed Lobster is elegant enough for a special occasion yet comforting enough for a cozy weeknight meal. Serve it hot, garnished with fresh parsley and a drizzle of olive oil. For a complete meal, consider pairing it with a side of crusty bread or a simple green salad.

Leftover bisque can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat, stirring occasionally. You can also freeze the bisque for up to 2 months. Thaw it overnight in the refrigerator before reheating. It is best to add the cream after thawing and reheating for the best texture. The sautéed lobster is best eaten fresh. However, if you have leftovers, store them separately in the refrigerator for up to 24 hours. Reheat gently before serving.
