Make Ahead Options
These Seafood Gratin preparations are ideal for busy home cooks looking to save time during the week! You can prep the seafood mixture (shrimp and scallops with seasoning) up to 24 hours in advance and store it in the refrigerator. Simply sauté the aromatics and combine everything in your baking dish, but hold off on adding the cheese until just before baking—this prevents it from becoming soggy. When you’re ready to serve, sprinkle the cheese on top and bake at 180°C (350°F) for about 15 minutes until bubbly. This way, you can enjoy deliciously creamy seafood gratin with minimal stress and maximum flavor!

Seafood Gratin Recipe FAQs
How do I choose the freshest seafood for my gratin?
Absolutely! When selecting shrimp and scallops, look for clear eyes and a slightly salty smell for shrimp. The shells should be shiny and moist, and the flesh should appear translucent. For scallops, seek out a translucent appearance and avoid any that have dark spots or an overly fishy odor. Always go for local and seasonal options if available – your gratin will thank you!
What’s the best way to store leftovers?
Very! Store your seafood gratin in an airtight container in the fridge for up to 2-3 days. Make sure to let it cool completely before sealing it up. To keep the cheese topping nice and fresh, cover it lightly with foil. This way, you can enjoy the savory flavors without any hassle.
Can I freeze seafood gratin?
Definitely! You can freeze the seafood gratin for up to 2 months. Before freezing, ensure it’s well-wrapped in plastic wrap and aluminum foil to ward off freezer burn. I recommend freezing it unbaked for the best taste. When ready to cook, simply thaw it in the fridge overnight and then bake as usual.
What if my seafood is overcooked?
Oh no! If you’ve overcooked your seafood, it may turn out a bit rubbery, but don’t fret! If it’s slightly overdone, a generous drizzle of extra heavy cream can help salvage the dish by adding moisture. Next time, pay close attention to the color changes; shrimp should be pink and scallops should appear opaque after about 3 minutes of cooking.
Can I make a vegetarian version of this gratin?
Absolutely! Create a delicious vegetarian seafood gratin by substituting seafood with a mix of sautéed mushrooms, zucchini, and spinach. I often add fresh herbs like thyme or basil for added flavor. Make sure to follow the cooking times as these veggies will require slightly different handling but will yield a hearty dish that’s just as creamy and comforting.
Is this dish safe for my pet?
Great question! While seafood can be a treat for pets, it’s best to keep this gratin away from your furry friends due to ingredients like garlic and onions, which are toxic to dogs and cats. Stick to plain, cooked seafood for pet treats, and they’ll enjoy it without any worries.
