Ingredients
- 200 g of scallops
- 150 g of peeled shrimp
- 200 g of fresh mushrooms
- 2 shallots
- 1 garlic clove
- 20 cl of heavy cream
- 1 glass of white wine
- 50 g of grated cheese
- 2 tablespoons of olive oil
- Salt and pepper
- 1 bunch of fresh parsley
Substitution Options
If you can’t find scallops, you can use additional shrimp or even some diced fish like cod. For the mushrooms, cremini or oyster mushrooms work well. If you prefer a lighter option, replace the heavy cream with half-and-half or a dairy-free alternative.
Preparation Section
Step 1: Preheat the Oven
Start by preheating your oven to 180°C (350°F). While the oven is heating up, gather all your ingredients and get ready to create magic in the kitchen.
Step 2: Sauté the Shallots and Garlic
Finely chop the shallots and garlic, then sauté them in a pan with olive oil on medium heat until they become translucent and fragrant. The aroma will already have you salivating!
Step 3: Add the Mushrooms
Stir in the sliced mushrooms and cook until they are golden brown. The mushrooms will release their natural juices, adding a depth of flavor to the dish. Pro tip: Don’t overcrowd the pan; cook the mushrooms in batches if necessary for the best caramelization.
Step 4: Cook the Seafood
Add the scallops and shrimp to the pan, followed by the white wine. Let it simmer for a few minutes until the alcohol evaporates. You’ll see the seafood turning pink and opaque, a sign that they’re perfectly cooked.
Step 5: Incorporate the Cream and Seasoning
Stir in the heavy cream, salt, and pepper. Mix well and let it cook for another 2 minutes. The creamy sauce will thicken slightly, coating the seafood and mushrooms beautifully.
Step 6: Assemble the Casseroles
Divide the mixture into individual cassolettes, then sprinkle with grated cheese and chopped parsley. The cheese will melt and create a delightful, golden crust.
Step 7: Bake to Perfection
Place the cassolettes in the preheated oven and bake for about 15 minutes, or until the tops are golden and bubbly. Chef’s tip: Use a broiler for the last minute to get a perfect, crispy top.
Timing
Plan your time wisely:
– Prep time: 20 minutes
– Cooking time: 25 minutes
– Total time: 45 minutes
Chef’s Secret
To enhance the flavor, add a pinch of nutmeg to the cream sauce. It adds a subtle, warm note that complements the seafood and cream perfectly.

Necessary Equipment
- Oven-safe cassolettes
- Large skillet
- Sharp knife
- Cutting board
- Wooden spoon
Storage
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or on the stovetop, adding a little milk or cream to keep the sauce creamy. Avoid microwaving, as it can make the seafood tough and the sauce lumpy. For longer storage, consider freezing the casserole before baking. Freeze it in a freezer-safe container for up to 3 months, and thaw overnight in the fridge before baking.
Tips and Advice
Make sure all your ingredients are fresh, especially the seafood. Freshness is key for the best flavor and texture. Also, don’t overcook the seafood; it should be tender and succulent. If you’re serving this to guests, you can prep the casserole ahead of time and bake it just before serving for a stress-free experience.
Presentation Tips
- Garnish with fresh parsley and a squeeze of lemon juice for a pop of color and freshness.
- Serve with a side of crusty bread or a simple green salad to balance the richness of the casserole.
- For a more elegant presentation, use small, individual ramekins and serve as a starter or a light main course.

Common Mistakes to Avoid
Mistake 1: Overcooking the Seafood
Overcooked seafood can become tough and rubbery, spoiling the dish. To avoid this, cook the scallops and shrimp just until they turn opaque and start to curl. They should still be slightly springy to the touch. Pro tip: Remove the seafood from the heat as soon as they are done to prevent overcooking.
Mistake 2: Not Using Enough Olive Oil
Using too little olive oil can result in the shallots and garlic burning rather than sautéing. Make sure to use enough oil to coat the pan and allow the aromatics to cook evenly. Pro tip: Add a small amount of butter along with the olive oil for extra flavor and richness.
Mistake 3: Not Preheating the Oven
Skipping the step of preheating the oven can lead to uneven cooking. Make sure the oven is fully preheated before baking the cassolettes. This ensures that the dish cooks evenly and forms a beautiful, golden crust. Pro tip: Use an oven thermometer to ensure the correct temperature.
Mistake 4: Not Tasting the Sauce
It’s crucial to taste and adjust the seasoning of the sauce before adding the seafood. A well-seasoned sauce enhances the overall flavor of the dish. Pro tip: Start with a little salt and pepper, then taste and adjust as needed.
Mistake 5: Overcrowding the Pan
Overcrowding the pan when sautéing the mushrooms can lead to steaming instead of browning. This results in a less flavorful dish. Pro tip: Cook the mushrooms in batches if necessary to ensure they get the proper caramelization.
