Step-by-Step Instructions
- Sauté the Aromatics
Heat butter and olive oil in a large pot over medium heat. Add onion and celery, cooking until soft and fragrant—about 4 minutes. Stir in garlic and cook for 30 seconds more. - Build Flavor
Mix in tomato paste, paprika, Old Bay, cayenne, salt, and pepper. The mixture should look glossy and smell smoky and savory. - Add Broth
Pour in seafood stock, scraping up any browned bits from the bottom of the pot. Let it gently simmer for 5 minutes. - Make It Creamy
Stir in heavy cream and cream cheese until melted and silky smooth. For ultra-velvety texture, blend briefly with an immersion blender. - Cook the Shrimp
Add chopped shrimp and simmer for 3–4 minutes until pink, tender, and juicy. - Fold in Crab
Gently stir in lump crab meat and lemon juice. Heat just until warmed—don’t boil. - Taste & Serve
Adjust seasoning, ladle into bowls, and garnish with herbs and extra cream for a restaurant-style finish.
