Sauté Aromatics: Melt butter in a medium pot over medium heat. Add onion and garlic, cooking until soft and fragrant.
Create the Base: Stir in flour and cook for 1 minute. Gradually whisk in the broth to avoid lumps. Mix in tomato paste, heavy cream, and milk, then simmer for 5 minutes.
Add Seafood: Gently fold in shrimp, crab meat, Old Bay seasoning, paprika, salt, and pepper.
Finish the Bisque: Stir in white wine (if using) and cook until the shrimp turn pink, about 3–5 minutes. Adjust seasoning to taste.
Serve: Ladle the bisque into bowls and garnish with freshly chopped parsley.
