It’s an elegant yet comforting dish that’s ideal for special dinners or when you want to impress guests with minimal effort.
Ingredients
To craft an exceptional Seafood Mornay, choosing the right ingredients is essential. We break down the key components to ensure the perfect blend of flavors and textures.
Seafood Selection
Our seafood choice sets the foundation for this dish’s delicate yet rich profile. We recommend a combination of tender, fresh options:
- 1/2 pound shrimp, peeled and deveined
- 1/2 pound scallops, cleaned
- 1/2 pound white fish fillets (e.g., cod or haddock), cut into chunks
- 1/4 pound crab meat, picked over for shells (optional for added sweetness)
These varieties offer a pleasing balance of sweetness, firmness, and subtle ocean flavor. Choosing fresh or sustainably sourced seafood will elevate the final dish.
Mornay Sauce Ingredients
The hallmark of our Seafood Mornay is the creamy, cheesy Mornay sauce. This sauce begins with a classic béchamel base enriched with cheese for deep umami:

Prep Work
Before we start combining flavors in our Seafood Mornay, proper prep work lays the foundation for success. Let’s get everything ready to ensure smooth cooking and an exceptional final dish.
Preparing the Seafood
Selecting and prepping fresh seafood is crucial. We recommend using a mix of shrimp, scallops, white fish fillets, and crab meat for that signature rich yet delicate profile.
- Shrimp: Peel and devein 1 pound of medium shrimp. Pat dry with paper towels.
- Scallops: Rinse ½ pound of sea scallops and remove the tough side muscle if present.
- White Fish Fillets: Choose firm, flaky fish such as cod or haddock. Cut into 1½-inch chunks.
- Crab Meat: Use about ½ cup of fresh or canned lump crab meat. Check for shell fragments.
Keep the seafood chilled until ready to cook to maintain freshness and texture.
| Seafood Type | Quantity | Prep Details |
|---|---|---|
| Shrimp | 1 pound | Peeled, deveined, patted dry |
| Scallops | ½ pound | Rinsed, muscle removed |
| White Fish | 1 pound | Cut into 1½-inch chunks |
| Crab Meat | ½ cup | Checked for shell bits, drained |
Preparing the Sauce Ingredients
The Mornay sauce combines a béchamel base enriched with cheese for a creamy, luscious texture. Preparing the ingredients beforehand makes the cooking process seamless.
- Shallots: Finely mince 2 medium shallots. Their subtle sweetness complements the seafood.
- Cheese: Grate 1 cup Gruyère and ½ cup Parmesan cheese freshly for optimal melting and flavor.
- Butter and Flour: Measure 4 tablespoons unsalted butter and 4 tablespoons all-purpose flour for the roux.
- Milk: Warm 3 cups whole milk to enhance the sauce’s creaminess without lumps.
- Seasonings: Prepare 1 teaspoon salt, ¼ teaspoon white pepper, and a pinch of freshly grated nutmeg.
- Extras: Zest of 1 lemon and 2 tablespoons chopped fresh parsley for bright accents.
Having these ingredients prepped and ready ensures our Mornay sauce develops that unmistakable velvety texture and rich flavor.
| Ingredient | Quantity | Preparation |
|---|---|---|
| Shallots | 2 medium | Finely minced |
| Gruyère Cheese | 1 cup | Freshly grated |
| Parmesan Cheese | ½ cup | Freshly grated |
| Unsalted Butter | 4 tablespoons | Measured |
| All-purpose Flour | 4 tablespoons | Measured |
| Whole Milk | 3 cups | Warmed |
| Salt | 1 teaspoon | Measured |
| White Pepper | ¼ teaspoon | Ground |
| Nutmeg | Pinch | Freshly grated |
| Lemon Zest | From 1 lemon | Zested |
| Fresh Parsley | 2 tablespoons | Chopped |
Making the Mornay Sauce
Crafting the perfect Mornay sauce is essential for our Seafood Mornay to shine. We will create a smooth, velvety base enriched with cheese that complements the delicate seafood flavors flawlessly.
Creating the Roux
We start by making a classic roux, the foundation of our creamy sauce. Here is the process step-by-step:
- Melt 4 tablespoons of unsalted butter in a heavy-bottomed saucepan over medium heat.
- Once melted, add 4 tablespoons of all-purpose flour all at once.
- Stir continuously with a wooden spoon or whisk for 2-3 minutes to cook the flour, ensuring the roux stays pale and smooth, avoiding any browning.
- This step removes the raw flour taste and builds the base structure for the sauce’s creamy texture.
Adding Milk and Cheese
Next, we transform the roux into a béchamel sauce and then enrich it to become a Mornay:
- Gradually whisk in 3 cups of whole milk, warmed to room temperature, to prevent lumps.
- Continue whisking over medium heat until the sauce thickens and coats the back of a spoon, about 6-8 minutes.
- Remove the sauce from heat.
- Stir in the cheeses for richness and flavor:
- 1 cup grated Gruyère cheese
- ½ cup grated Parmesan cheese
- Mix until the cheese melts completely, creating a smooth, gooey texture.
| Ingredient | Quantity | Purpose |
|---|---|---|
| Butter | 4 tbsp | Roux base |
| Flour | 4 tbsp | Thickening agent for sauce |
| Milk | 3 cups (warmed) | Gives creamy béchamel texture |
| Gruyère cheese | 1 cup (grated) | Adds rich, nutty flavor |
| Parmesan cheese | ½ cup (grated) | Sharpens cheese flavor profile |
Seasoning the Sauce
To elevate the Mornay sauce perfectly, we season with precision:
- Add salt and white pepper to taste, keeping the seasoning delicate to complement the seafood.
- Grate a pinch of fresh nutmeg into the sauce; its warmth enhances the depth without overpowering.
- Optionally, stir in finely minced shallots sautéed in butter for a subtle aromatic lift.
- For brightness, finish with a touch of fresh lemon zest or chopped parsley before combining with seafood.
These seasonings balance the sauce’s richness and make our Seafood Mornay truly irresistible.
Cooking the Seafood
To achieve the perfect texture and flavor in our Seafood Mornay, cooking the seafood properly is essential. Whether we choose to sauté or poach, precision and gentle handling will preserve the delicate taste and tender bite of the seafood.
Sautéing or Poaching Seafood
We have two excellent cooking methods for our seafood: sautéing and poaching. Each method enhances the seafood differently and complements the rich Mornay sauce.
-
Sautéing Seafood
- Heat a large sauté pan over medium-high heat and add a tablespoon of unsalted butter or neutral oil such as grapeseed oil.
- When the butter melts and foams or the oil shimmers, add the prepared seafood in a single layer without crowding the pan.
- Cook shrimp and scallops for about 2 minutes per side until they turn opaque and develop a light golden crust. White fish fillets need approximately 3–4 minutes per side.
- Season lightly with salt and white pepper during cooking. Avoid overcooking — seafood should be just cooked through and tender to the bite.
- Remove seafood from heat and set aside while we finish the sauce.
- In a shallow skillet or saucepan, combine 1 cup of dry white wine with 1 cup of water or fish stock.
- Add a few sprigs of fresh parsley, a crushed garlic clove, and a pinch of salt for subtle aromatic infusion.
- Bring the liquid to a gentle simmer over medium heat.
- Gently add seafood in a single layer and poach for 3–5 minutes, depending on size — shrimp and scallops until just opaque, fish until flakes easily with the fork.
- Avoid boiling or rapid bubbling to prevent toughening the seafood.
- Remove seafood with a slotted spoon and drain well before adding to the sauce.
| Cooking Method | Heat Level | Cooking Time | Key Notes |
|---|---|---|---|
| Sautéing | Medium-high heat | 2 min per side (shrimp) | Develops slight golden crust |
| 3-4 min per side (fish) | Avoid overcrowding pan | ||
| Poaching | Gentle simmer | 3-5 min | Infused with aromatics, very tender seafood |
| Do not boil, keep liquid at gentle simmer |
“The key to a luscious Seafood Mornay lies in perfectly cooking the seafood — tender, flavorful, yet not overdone — to harmonize beautifully with the creamy, cheesy sauce.“
By following these techniques, we lock in the fresh seafood flavors and textures that make our Seafood Mornay a standout dish.
Combining Seafood and Sauce
To create the perfect Seafood Mornay, the final step is to delicately combine the cooked seafood with the rich, creamy Mornay sauce. This process ensures each bite delivers a harmonious blend of flavors and textures that define this classic dish.
Mixing and Heating Together
- Prepare the Seafood: Ensure the seafood is cooked just until tender, whether sautéed or poached, to maintain its delicate texture and avoid overcooking.
- Gentle Incorporation: Transfer the cooked seafood into the saucepan containing the warm Mornay sauce. Use a wooden spoon or silicone spatula to fold the seafood gently into the sauce. This preserves the shape and integrity of the shrimp, scallops, fish fillets, and crab meat.
- Low Heat Warming: Place the saucepan over low heat. Slowly warm the mixture, stirring gently but continuously to prevent the sauce from scorching or becoming grainy. Heating for 3 to 5 minutes allows the seafood to absorb the rich flavors of the sauce without losing moisture.
- If the sauce thickens too much during warming, add a splash of warm milk or a few tablespoons of reserved seafood cooking liquid to loosen it.
- Taste and adjust the seasoning with salt, white pepper, or a pinch of nutmeg to maintain balanced flavor.
| Step | Action | Purpose |
|---|---|---|
| 1 | Cook seafood properly | Preserve tender texture |
| 2 | Fold seafood into Mornay sauce | Keep seafood intact |
| 3 | Warm over low heat | Blend flavors and prevent curdling |
| 4 | Adjust consistency and seasoning | Perfect sauce texture and taste |
“The key to an impeccable Seafood Mornay lies in the gradual, gentle blending of the seafood with the velvety sauce, letting the layers of flavor intertwine without disturbing the delicate seafood texture.”
By mastering this combination step, we ensure our Seafood Mornay is rich, creamy, and bursting with fresh ocean flavors, ready for finishing touches or serving immediately.
Baking (Optional)
Baking Seafood Mornay adds a golden bubbly crust that elevates both the texture and presentation. This step is optional but highly recommended when serving guests or aiming for a more polished finish.
Preparing for Baking
To prepare for baking, first preheat the oven to 375°F (190°C). This temperature ensures even cooking without over-drying the seafood. Transfer the combined seafood and Mornay sauce into a lightly buttered oven-safe baking dish for optimal heat distribution and to prevent sticking.
Next, sprinkle a generous layer of finely grated Gruyère cheese evenly over the top. This cheese melts beautifully, creating a rich, golden crust. For added texture and flavor, we like to finish with a light dusting of freshly grated Parmesan and optional breadcrumbs. These enhance crispness and add an inviting aroma.
Finally, place the dish on the middle rack to promote balanced browning and avoid burning.
Baking Instructions
| Step | Action | Details | Time |
|---|---|---|---|
| 1 | Preheat oven | Set to 375°F (190°C) | 10 minutes |
| 2 | Transfer mixture | Spread gently in a buttered oven-safe dish | N/A |
| 3 | Add toppings | Sprinkle with Gruyère, Parmesan, and optional crumbs | N/A |
| 4 | Bake | Place in middle oven rack | 15-20 minutes |
| 5 | Check for golden crust | Look for bubbling sauce and lightly browned cheese crust | End of baking |
| 6 | Rest before serving | Let sit 5 minutes to set | 5 minutes |
Pro Tip: Avoid overbaking which can dry out the mussels and scallops; the goal is a warm, bubbly sauce and a golden top.
Once baked, the Seafood Mornay should present with a bubbly, aromatic crust complementing the creamy rich base beneath. This optional baking step lends an elegant, restaurant-quality finish to our classic dish.
