- ½ teaspoon sea salt
Adjust to taste

Method
- 1
Heat a large, heavy-bottomed pan over medium-high heat. Add the lobster shells (or roughly chopped whole lobster), chopped onions, celery, and carrots. Cook for 5 minutes, stirring occasionally, until the shells begin to take on colour and the vegetables soften. This develops a deeper, richer flavour base.
~5 minsTip: This browning step is crucial for flavour and should not be skipped, even though you're using a slow cooker.
- 2
Transfer the browned shell and vegetable mixture to your slow cooker. Add the fish or seafood stock, bay leaves, and thyme sprigs. Stir well to combine.
~2 mins - 3
Cover and cook on Low for 6 hours or High for 4 hours. The longer, slower cooking allows maximum flavour extraction from the lobster shells and aromatics.
~6 hrsTip: Do not lift the lid unnecessarily as this extends cooking time.
- 4
Strain the bisque through a fine sieve or colander lined with muslin into a clean bowl or the slow cooker's ceramic pot (if removable). Discard the shells, vegetables, and herbs. Press gently on the solids to extract as much liquid and flavour as possible, but do not crush or force them through.
~10 minsTip: A smooth bisque is essential. Take time with this straining step.
- 5
In a small bowl, make a beurre manié by mixing the softened butter and flour into a smooth paste with a fork. If your bisque is still in the slow cooker, turn it to High setting. Whisk the beurre manié into the hot bisque in small pieces until fully incorporated. This will thicken the bisque to a luxurious, velvety consistency.
~5 minsTip: Whisking ensures a lump-free, silky texture. Alternative: you can make a separate roux in a pan and gradually whisk in some hot bisque before combining.
- 6Optional step
If using sherry or cognac, add it now and stir well. Let the bisque simmer on High for 2 minutes to allow the alcohol to cook off slightly and the flavours to integrate.
~2 minsTip: This step adds elegance and depth but is optional.
- 7
In the final 30 minutes before serving, stir in the double cream slowly, whisking constantly until fully incorporated and the soup reaches your desired richness. Season carefully with sea salt and white pepper to taste. The bisque should be smooth, glossy, and luxuriously creamy.
~30 minsTip: Adding cream late prevents curdling and preserves its delicate flavour. Taste as you season.
- 8
Ladle the bisque into warm serving bowls. Top each bowl with a small dollop of crème fraîche, a light scatter of fresh tarragon or chervil, and a few grinds of white pepper. Serve immediately.
~5 minsTip: Presentation elevates this elegant soup for special occasions.

Frequently Asked Questions
Yes, you can purchase cooked lobster meat and ask your fishmonger for lobster shells separately, or use a high-quality lobster or seafood stock as your base. However, cooking whole lobsters or using fresh shells will give you the most authentic and deeply flavoured result. If using only meat, reduce the cooking time slightly and ensure your stock is of superior quality to compensate
