Keto Lobster Bisque

Why This Is Strictly Keto

Classic bisque is thickened with a flour roux or rice. This one gets its body from reducing real broth with tomato paste and heavy cream, so there is no flour, rice or starch — just lobster, butter, vegetables and cream.

Ingredients

• 3 tablespoons butter
• ½ yellow onion, finely chopped
• 1 celery stalk, finely chopped
• 2 cloves garlic, minced
• 2 tablespoons tomato paste
• 3 cups (720 ml) seafood or chicken broth
• 1 cup (240 ml) heavy cream
• 12 ounces (340 g) cooked lobster meat, chopped
• 1 teaspoon fresh thyme leaves
• ¼ teaspoon cayenne pepper
• Salt and black pepper, to taste
• 1 tablespoon lemon juice

Instructions

1. Sauté the vegetables: Melt the butter in a large pot over medium heat. Cook the onion and celery for 5 minutes until soft, then stir in the garlic for 1 minute.

2. Add the tomato paste: Stir in the tomato paste and cook for 2 minutes to deepen its flavor.

3. Simmer: Pour in the broth, add the thyme and cayenne, and simmer for 15 minutes.

4. Blend: Use an immersion blender to purée the soup until smooth.

5. Finish: Stir in the cream and lobster and warm gently for 5 minutes without boiling. Season with salt, pepper and lemon juice.

Tips

• Lobster tail meat works beautifully; buy cooked tails or steam them yourself for 8 minutes.
• Do not let the soup boil after the cream goes in, or it can separate and the lobster can turn tough.
• A homemade shellfish stock made from the lobster shells adds even more depth.
