Step-by-Step Cooking Guide

Step 1 – Prepare the Seafood

Season shrimp, fish, and crab with lemon juice, salt, and pepper. Set aside for 10 minutes.

Step 2 – Make the Creamy Sauce

In a pan, melt butter over medium heat. Add flour and cook for 1–2 minutes to form a roux.

Slowly whisk in milk and cream, stirring continuously until the sauce thickens. Add garlic, paprika, oregano, salt, and pepper. Cook for another 2–3 minutes.

Step 3 – Cook the Seafood

Add the seasoned seafood into the sauce and cook gently for 3–5 minutes until just tender. Do not overcook.

Step 4 – Assemble the Gratin Cake

Preheat oven to 180°C (350°F). Grease a baking dish.

Pour the seafood mixture into the dish and spread evenly.

Step 5 – Add Topping

Mix breadcrumbs with olive oil and sprinkle over the top. Add mozzarella and cheddar cheese evenly.

Step 6 – Bake

Bake for 20–25 minutes or until the top is golden brown and bubbly.

Step 7 – Rest & Serve

Let the gratin rest for 5–10 minutes before slicing into portions.
