Ingredients You’ll Need
The magic of this recipe lies in its simplicity. Each ingredient plays a pivotal role in building depth, richness, and that crave-worthy creamy texture that transforms humble seafood into a decadent treat.
- Shrimp (1 pound, peeled and deveined): Provides a sweet, tender bite and cooks quickly ensuring the gratin stays delicate.
- Scallops (1 pound, fresh or thawed frozen): Adds buttery richness and a slightly chewy texture that pairs beautifully with the shrimp.
- Butter (2 tablespoons for sautéing): Helps in gently softening the onions and garlic while imparting a silky base to the cream sauce.
- Onion (1 medium, chopped): Adds a subtle sweetness and fragrant depth when caramelized softly.
- Garlic (2 cloves, minced): Brings a warm, aromatic earthiness that lifts the creamy sauce.
- Heavy Cream (1 cup): The star ingredient that creates the velvety, rich consistency essential for the gratin.
- White Grape Juice (1/2 cup, or substitute with white wine): Adds a subtle fruity acidity to balance the richness and brighten the flavors.
- Grated Cheese (1 cup, Gruyère or cheddar): Melts into the sauce creating a golden, bubbly crust with notes of nuttiness and tang.
- Salt (to taste): Enhances all the flavors, bringing harmony to the dish.
- Black Pepper (to taste): Adds a gentle kick and sharpness that complements the creamy base.
How to Make Irresistibly Creamy Seafood Gratin Recipe for Cozy Nights Recipe
Step 1: Prepare the Seafood
Begin by rinsing your shrimp and scallops under cold water, then pat them dry with a paper towel. This step is key to ensure the seafood sears nicely and doesn’t steam in the pan. Set aside while you prepare the aromatics – patience here will pay off in taste!
Step 2: Sauté Onions and Garlic
Melt the butter in a large skillet over medium heat. Add the chopped onions and cook them gently until they’re soft and translucent, about 5 minutes. Then toss in the minced garlic and continue to sauté for another minute until fragrant. This forms the wonderful flavor base your creamy sauce needs.
Step 3: Cook the Seafood
Increase the heat to medium-high and add the shrimp and scallops to the skillet. Cook for about 3-4 minutes, just until they start to turn opaque. Don’t overcook here – the seafood will finish cooking in the oven, so you want to retain that tender texture.
Step 4: Deglaze with White Grape Juice
Pour in the white grape juice or white wine, scraping the bottom of the pan gently to lift all those lovely caramelized bits. This fruity liquid cuts through the richness and adds a delicate brightness to the dish.
Step 5: Add Heavy Cream and Simmer
Lower the heat and stir in the heavy cream, allowing everything to gently bubble for 3-5 minutes. This lets the flavors marry beautifully while the sauce thickens into that irresistibly creamy consistency we’re aiming for.
Step 6: Season and Assemble
Adjust seasoning with salt and pepper to taste. Transfer the seafood and cream mixture into a gratin dish. Evenly sprinkle the grated cheese on top, which will toast into a golden, bubbly crust when baked.
Step 7: Bake to Perfection
Place the dish in a preheated oven at 375ºF (190ºC) and bake for about 20 minutes or until the top is beautifully golden and bubbling. This final step melds the creamy sauce with the cheese topping, creating the perfect cozy night meal.
How to Serve Irresistibly Creamy Seafood Gratin Recipe for Cozy Nights Recipe

Garnishes
A sprinkle of fresh chopped parsley or chives adds a pop of color and a light herbal note that balances the creaminess wonderfully. A squeeze of lemon over the top just before serving can also brighten flavors and elevate the seafood charm.
Side Dishes
Pair your gratin with a crisp green salad tossed in a tangy vinaigrette to cut through the richness, or try some crusty garlic bread for sopping up every last bit of that luscious sauce. Lightly roasted vegetables also make a lovely accompaniment without overwhelming the star seafood flavors.
Creative Ways to Present
Serve this gratin straight from the oven in individual ramekins for a charming, intimate presentation. Alternatively, place in a rustic cast-iron skillet for a more family-style feel that invites communal sharing – nothing brings warmth like food savored together!
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and refrigerate for up to 2 days. The flavor actually develops further, making it a great option for next-day indulgence that still holds that creamy texture.
Freezing
While best enjoyed fresh, you can freeze the gratin in a freezer-safe dish before baking. Wrap it tightly in foil and plastic wrap to prevent freezer burn, and it will keep for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in a 325ºF (160ºC) oven until warmed through and the cheese topping bubbles again, about 15-20 minutes. Avoid microwaving, which can cause the sauce to separate and the texture to suffer.
FAQs
Can I use other types of seafood?
Absolutely! This recipe is quite versatile. Feel free to swap in lobster, crab, or firm white fish chunks, just adjust cooking times accordingly so everything stays tender and juicy.
What cheese works best for gratins?
Gruyère is a classic pick for gratins because it melts beautifully and adds a nutty flavor. Sharp cheddar is an excellent more accessible alternative that also provides great melt and bite.
Is it possible to make this recipe dairy-free?
You can substitute heavy cream with coconut cream and use dairy-free butter and cheese alternatives to create a creamy texture while keeping it dairy-free. The flavor will shift but remain delightful.
Can I prepare the sauce ahead and bake later?
Yes! You can prepare the seafood and cream sauce ahead, store it in the fridge, and add cheese just before baking. This can save time on busy evenings and still yield a fresh, warm gratin.
How can I make the sauce less rich?
Try using half heavy cream and half milk or a lighter cream version. Adding a splash more white grape juice or wine can also help cut richness without sacrificing flavor.

Ingredients
Seafood
- 1 pound Shrimp (peeled and deveined)
- 1 pound Scallops (fresh or thawed frozen)
Sauce
- 2 tablespoons Butter (for sautéing)
- 1 medium Onion (chopped)
- 2 cloves Garlic (minced)
- 1 cup Heavy Cream
- 1/2 cup White Grape Juice (or substitute with white wine)
Topping and Seasoning
- 1 cup Grated Cheese (Gruyère or cheddar recommended)
- Salt (to taste)
- Black Pepper (to taste)
Instructions
- Prepare Seafood: Rinse the shrimp and scallops under cold water and pat them dry with paper towels. Ensure shrimp are peeled and deveined to enhance taste and texture.
- Sauté Aromatics: In a large skillet, melt the butter over medium heat. Add the chopped onion and minced garlic, sautéing until the onions are translucent and fragrant, about 3-5 minutes.
- Cook Seafood: Add the shrimp and scallops to the skillet with the aromatics. Cook gently until the seafood just starts to turn opaque, approximately 3-4 minutes, stirring occasionally to avoid sticking.
- Add Liquid Ingredients: Pour in the heavy cream and white grape juice (or white wine). Stir to combine and bring to a gentle simmer. Allow it to cook for about 5-7 minutes, letting the sauce thicken slightly and the flavors meld.
- Season the Mixture: Season the gratin with salt and black pepper to taste. Adjust seasoning carefully considering the saltiness of the cheese.
- Assemble the Gratin: Transfer the seafood and sauce mixture to a baking dish if your skillet is not oven safe. Sprinkle the grated cheese evenly over the top.
- Bake the Gratin: Preheat the oven to 375°F (190°C). Bake the assembled gratin for 15-20 minutes or until the cheese is melted, bubbly, and golden brown.
- Serve: Remove the gratin from the oven and let it rest for a few minutes before serving. This will help the sauce thicken slightly and enhance the creamy texture.
