Seafood Gratin Pasta Bake Ingredients
For the Pasta

For Sautéing
• Olive Oil – perfect for sautéing seafood and leeks; butter can be used for extra flavor.
• Mixed Raw Seafood – a delightful mix including shrimp, fish, calamari, and mussels; feel free to use any preferred seafood for this Seafood Gratin Pasta Bake.
• Leeks – adds a sweet, aromatic depth; if unavailable, shallots or green onions work well.
• Garlic – enhances the overall flavor profile; can use garlic powder as an easy substitute.
For the Béchamel Sauce
• Butter – essential for creating a rich white sauce; margarine can be used for a dairy-free option.
• Flour – forms the roux for thickening the sauce; gluten-free flour can be used if needed.
• Milk – the creamy base of the sauce; plant-based milk is a great dairy-free alternative.
• Chicken Bouillon Cube/Stock – adds depth of flavor; vegetable or homemade seafood stock can elevate the taste even more.
For the Topping
• Panko – provides a delightful crunch; regular breadcrumbs can substitute if preferred.
• Grated Parmesan Cheese – enriches the topping with a burst of flavor; nutritional yeast is an excellent vegan alternative.
• Fresh Parsley (optional) – garnishes with a pop of color and freshness; feel free to omit if not available.
How to Make Seafood Gratin Pasta Bake
Preheat your oven to 180°C (350°F). This initial step will ensure your dish bakes evenly and comes out perfectly golden brown on top.
Cook the macaroni according to package instructions until al dente, then drain and spread it evenly in a baking dish. This forms the hearty base for your Seafood Gratin Pasta Bake.
Sear the mixed seafood! Heat 1 tablespoon of olive oil in a skillet over high heat, then sear the seafood for about 30 seconds on each side until it’s just undercooked. Remove and set aside in the baking dish.
Sauté the leeks and garlic by adding the remaining olive oil to the skillet. Cook until softened, about 3 minutes, then mix them into the baking dish with the pasta and seafood.
Make the béchamel sauce by melting the butter in the skillet, adding flour, and stirring constantly for 1 minute. Gradually whisk in the milk, and keep stirring until the mixture thickens, around 5 minutes. Stir in the bouillon cube, and season with salt and pepper.
Combine the sauce with the pasta mixture in the baking dish, ensuring everything is well coated. Then, top generously with panko and grated Parmesan for that delicious crispy crust.
Bake for 20-25 minutes, or until golden brown and bubbly. Allow it to rest for 5 minutes before diving in and serving!
Optional: Garnish with fresh parsley for a pop of color and additional freshness.
