Step-by-step instructions
- Begin by preheating your oven to 200°C (390°F).
- In a saucepan, melt the butter over medium heat. Add the minced garlic and sauté for a minute until fragrant.
- Gradually stir in the flour, creating a roux. Cook for another minute.
- Slowly whisk in the milk, ensuring there are no lumps, until the mixture thickens into a béchamel sauce.
- Season your béchamel with salt, pepper, and a pinch of nutmeg.
- Fold in the mixed seafood and half of the grated cheese, incorporating everything evenly.
- Pour the mixture into a suitable baking dish and sprinkle the remaining cheese on top.
- Bake for 20 to 25 minutes until the gratin is golden and bubbly.
Best ways to enjoy it
When it comes to serving seafood gratin, the possibilities are endless! For a rustic touch, serve it directly from the baking dish. Pair it with a crisp green salad dressed lightly with lemon vinaigrette to balance the richness. For a more filling option, consider accompanying it with crusty bread or a side of garlic mashed potatoes.
Storage and reheating tips
If you’re fortunate enough to have leftovers, storing your seafood gratin is simple. Allow it to cool completely before covering it with foil or plastic wrap and refrigerating for up to three days. For the best experience, reheat in the oven at 180°C (350°F) until warmed through. This will help maintain that crispy top.
Extra advice
- Make it creamy: For an extra creamy texture, add a splash of cream to the béchamel.
- Cheese variety: Feel free to experiment with different cheeses like Parmesan or mozzarella for varied flavors.
- Herbs and spices: Fresh herbs, such as parsley or dill, can elevate the dish significantly; sprinkle them over right before serving.
Creative twists
Why not experiment with different flavor profiles? Add a hint of spice with crushed red pepper flakes, or incorporate some sautéed mushrooms for an earthy twist. If you’re looking for a lighter version, swap out the béchamel for a simple lemon-butter sauce to accompany the seafood.
