In a large heavy-bottomed pot, melt the ghee over medium heat.
Add the diced yellow onion, celery, and carrots, sautéing for 5-7 minutes until the vegetables are softened and translucent.
Stir in the minced garlic and tomato paste, cooking for 1 minute until the paste turns a deep red color.
Pour in the dry sherry to deglaze the pot, using a wooden spoon to scrape up any flavorful bits from the bottom.
Add the seafood stock, sea salt, black pepper, and smoked paprika, then bring the mixture to a gentle simmer for 15 minutes.
Use an immersion blender to process the soup directly in the pot until it is completely smooth and velvety.
Stir in the heavy cream and the cooked lobster meat, heating through for 3 minutes without letting the bisque reach a boil.
Ladle the bisque into warm bowls and garnish with finely chopped fresh chives.
