1) Melt Butter: In a large, heavy pot over medium heat, melt butter.
2) Cook Aromatics: Add onions, carrots, and celery. Cook until softened, about 7 minutes. Season with salt and pepper.
3) Add Garlic & Tomato Paste: Stir in garlic and tomato paste. Cook until fragrant and the paste coats the vegetables, about 2 minutes.
4) Incorporate Flour: Sprinkle flour over the mixture and cook, stirring constantly, for 1 minute.
5) Deglaze & Simmer: Pour in seafood stock and wine. Stir in the bay leaf and thyme. Bring to a simmer, then reduce heat. Let the soup simmer uncovered, stirring occasionally, until the liquid is slightly reduced and flavors meld, about 30 minutes.
6) Blend Smooth: Remove the bay leaf and thyme sprigs. Use an immersion blender to purée the soup until very smooth.
8) Finish the Bisque: Return the pot to medium-low heat. Stir in the heavy cream and lobster meat, and cook gently until warmed through, about 5 minutes.
9) Serve & Garnish: Ladle into bowls, garnish with chives, and serve immediately.
