Ingredients for Seafood Gratin with Mushrooms

To make a delicious seafood gratin with mushrooms, you will need the following ingredients:

Main Ingredients:

• 300 g mixed seafood (shrimp, mussels, calamari): This trio of seafood adds variety and flavor to the gratin. If you prefer, you can use just one type of seafood or a different combination based on availability.
• 200 g mushrooms (sliced): Mushrooms add a savory, earthy flavor to the dish. You can use white button mushrooms, cremini, or even wild mushrooms for added depth.
• 1 onion (finely chopped): Onions provide a touch of sweetness and depth to the sauce.
• 2 garlic cloves (minced): Garlic is a must for seasoning and enhancing the overall flavor profile.
• 2 tbsp butter: Butter creates a rich and creamy base for the sauce.
• 1 tbsp olive oil: Olive oil adds a smooth richness to the cooking process.
• 200 ml heavy cream (30%): The cream is the backbone of the sauce, giving it a luxurious, smooth texture.
• 100 ml white wine: White wine adds acidity and brightness to balance the richness of the cream.
• 100 g Gruyère or Parmesan cheese (grated): Cheese is what gives the gratin its signature golden, crispy top and adds a layer of savory goodness.
• 1 tbsp flour: The flour helps thicken the sauce and create the perfect texture.
• ½ tsp salt: Salt enhances all the flavors and is essential for seasoning.
• ¼ tsp black pepper: Black pepper adds a bit of heat and sharpness to balance the creaminess.
• ¼ tsp nutmeg: Nutmeg adds a warm, slightly sweet spice that pairs wonderfully with creamy sauces.
• 50 g breadcrumbs: Breadcrumbs create the golden crust on top of the gratin.
• 1 tbsp fresh parsley (chopped): Parsley adds a pop of color and freshness to the final dish.

Instructions for Preparing Seafood Gratin with Mushrooms

Step 1: Preheat the Oven

Start by preheating your oven to 190°C (375°F). This will ensure that the oven is hot and ready to bake the gratin when it’s time. Don’t forget to grease your baking dish with a bit of butter or cooking spray to prevent sticking.

Step 2: Sauté Onions and Garlic

In a large pan, heat the olive oil and 1 tbsp butter over medium heat. Once the butter has melted, add the finely chopped onion and minced garlic. Sauté the onions and garlic until they become soft and translucent, about 3-4 minutes. This step infuses the butter and oil with wonderful aromatic flavors.

Step 3: Cook the Mushrooms

Add the sliced mushrooms to the pan and cook for an additional 3-4 minutes until they begin to soften and release their moisture. Mushrooms cook down quickly, and you’ll want them to release some of their natural juices to form the base of your sauce.

Step 4: Add Flour and White Wine

Sprinkle the flour over the mushrooms and stir it in. Allow the flour to cook for about a minute to remove the raw taste. Then pour in the white wine and let it simmer for 2 minutes. This helps to deglaze the pan and add a bit of acidity to balance the richness of the cream.

Step 5: Make the Sauce

Next, pour in the heavy cream, and season the mixture with salt, black pepper, and nutmeg. Stir everything together and cook for 3-4 minutes, allowing the sauce to thicken slightly. The sauce should have a creamy consistency, but not too thick—remember, it will continue to thicken slightly as it bakes.

Step 6: Add Seafood

Stir in the mixed seafood (shrimp, mussels, and calamari). Cook for just 2-3 minutes to warm the seafood through. Be careful not to overcook the seafood at this stage, as it will continue to cook in the oven.

Step 7: Transfer to Baking Dish

Once the seafood is mixed in, transfer the entire mixture into the greased baking dish. Spread it out evenly, making sure the seafood and mushrooms are well-distributed.

Step 8: Add Cheese and Breadcrumbs

Sprinkle the grated cheese (Gruyère or Parmesan) evenly over the top of the seafood mixture. Then, add the breadcrumbs on top of the cheese for a crispy, golden crust. Dot the top with the remaining 1 tbsp butter to ensure the gratin gets a nice, buttery finish.

Step 9: Bake

Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the top is golden brown and bubbling. You’ll know it’s ready when the cheese has melted and the edges of the gratin have become crispy.

Step 10: Garnish and Serve

Once baked, remove the gratin from the oven and let it cool for a few minutes. Garnish with fresh chopped parsley before serving to add a touch of color and freshness.

Serve your seafood gratin with mushrooms warm, paired with a crisp salad, or alongside a loaf of crusty bread for a full meal. It’s the perfect balance of creamy, cheesy, and savory flavors that will have everyone coming back for seconds!
