While most of the ingredients for this seafood au gratin recipe are commonly found in your kitchen, you might need to visit the supermarket for fresh shrimp and scallops.

Ingredients For Seafood Au Gratin Recipe
Shrimp: Peeled and deveined, these add a sweet and tender texture to the dish.
Scallops: Provide a delicate and slightly sweet flavor that pairs well with the creamy sauce.
Heavy cream: Adds richness and a smooth texture to the gratin.
Parmesan cheese: Offers a sharp, nutty flavor that enhances the overall taste.
Cheddar cheese: Brings a creamy and slightly tangy element to the dish.
Butter: Adds a rich, buttery flavor and helps to create a smooth sauce.
Salt: Enhances the natural flavors of the seafood and cheese.
Black pepper: Adds a hint of spice and depth to the dish.
Parsley: Provides a fresh, herbaceous garnish that brightens the final presentation.
Technique Tip for This Recipe
When preparing the shrimp and scallops, make sure they are thoroughly dried with paper towels before mixing them with the other ingredients. Excess moisture can dilute the heavy cream and prevent the cheese from forming a proper crust. For an extra layer of flavor, consider searing the seafood in a hot pan with a bit of butter before combining it with the cream and cheese. This will add a delightful caramelized note to your Seafood Au Gratin.

How to Store / Freeze This Dish
- Allow the seafood au gratin to cool completely at room temperature before storing.
- Transfer the leftovers to an airtight container. Ensure the container is sealed tightly to maintain freshness.
- Store the container in the refrigerator if you plan to consume the dish within 2-3 days. The flavors will meld together beautifully, making it even more delicious.
- For longer storage, consider freezing the seafood au gratin. Place the cooled dish in a freezer-safe container or wrap it tightly with aluminum foil and then plastic wrap to prevent freezer burn.
- Label the container with the date to keep track of its freshness. The seafood au gratin can be frozen for up to 2 months.
- When ready to reheat, thaw the frozen dish in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor of the seafood.
- Preheat your oven to 350°F (175°C). Transfer the thawed seafood au gratin to an oven-safe dish if it was stored in a non-oven-safe container.
- Cover the dish with aluminum foil to prevent the top from over-browning and bake for 20-25 minutes, or until heated through. Remove the foil for the last 5 minutes to allow the top to become bubbly and golden.
- Garnish with fresh chopped parsley before serving to add a touch of freshness and color to your reheated seafood au gratin.
How to Reheat Leftovers
- Preheat your oven to 350°F (175°C). Place the seafood au gratin in an oven-safe dish, cover with aluminum foil to retain moisture, and bake for about 15-20 minutes until heated through.
- For a quicker option, use a microwave. Transfer a portion of the seafood au gratin to a microwave-safe dish, cover with a microwave-safe lid or plastic wrap (leaving a small vent), and heat on medium power for 2-3 minutes. Stir halfway through to ensure even heating.
- If you prefer a stovetop method, place the seafood au gratin in a skillet over medium-low heat. Add a splash of heavy cream or milk to prevent drying out, and stir occasionally until warmed through.
- For a crispy top, use a broiler. Preheat the broiler on low, place the seafood au gratin in an oven-safe dish, and broil for 3-5 minutes, watching closely to avoid burning. This method works best if the dish is already mostly reheated using another method.
