Step-by-Step Instructions
Step 1: Prepare the Seafood
Clean and pat dry all seafood. Remove any shells from shrimp and check mussels for freshness.
Step 2: Sauté Aromatics
In a large skillet, melt butter over medium heat. Add shallots and garlic, cooking until fragrant and translucent.
Step 3: Deglaze with Wine
Pour in white wine and simmer for 2–3 minutes to reduce slightly. This builds a flavorful base for the sauce.
Step 4: Add Cream and Seasoning
Stir in heavy cream and Dijon mustard. Simmer gently until slightly thickened. Season with salt, pepper, and optional paprika or saffron.
Step 5: Cook the Seafood
Add mussels first and cover until they start opening (about 3–5 minutes). Then add fish fillets, shrimp, and scallops. Simmer until seafood is cooked through and tender.
Step 6: Finish and Garnish
Stir in fresh parsley. Serve immediately in individual casseroles or a large serving dish, garnished with lemon wedges.
💡 Pro Tip: Avoid overcooking seafood to maintain tenderness and flavor.
