Ingredients & Why They Work

This Seafood Crepes with Béchamel Sauce and Gruyère Recipe blends simple, fresh ingredients that complement each other beautifully — from silky crepes to rich béchamel, tender seafood to nutty cheese. Choosing quality seafood and good Gruyère makes all the difference here, so keep that in mind next time you grab your shopping list.

• Eggs: Essential for tender, elastic crepes that hold the filling without tearing.
• Butter (unsalted): Melted in the crepe batter for richness and used in béchamel and greasing pans to get that perfect texture and flavor.
• All-purpose flour: Provides structure in both crepes and béchamel; key to getting a smooth sauce and thin crepes.
• Milk: Whole milk for a creamy béchamel, plus a mix of milk and water in the crepes to keep them light.
• Shrimp & Scallops: The stars of the seafood filling—fresh or well-defrosted for the best texture and flavor.
• Olive oil: For sautéing seafood and veggies; adds a fruity depth without overwhelming the dish.
• Onion & Mushrooms: Build extra savoriness and texture in the filling, balancing the seafood’s sweetness.
• White wine: Adds acidity and depth; helps deglaze the pan and intensifies the filling’s flavor.
• Parsley: Adds freshness and a pop of color in the filling.
• Gruyère cheese: Melts beautifully on top, creating a golden crust with a mild nuttiness that complements everything.

Tweak to Your Taste

I love making this recipe my own by swapping in different types of seafood or adjusting the cheese, and I encourage you to experiment too! You can easily create a version that works for your dietary needs or just switch it up for seasonal ingredients.

• Seafood Swaps: I once tried crab and mussels instead of shrimp and scallops and loved how they added new textures and flavors—definitely a must-try!
• Cheese Variations: Mozzarella works great if you prefer something milder, while Emmental gives a slightly sweeter note.
• Make It Vegetarian: Skip the seafood and load up with roasted vegetables and mushrooms for a satisfying veggie alternative.
• Spice It Up: Adding a pinch of cayenne or some smoked paprika to the béchamel can give a subtle kick without overpowering the delicate seafood.

Step-by-Step: How I Make Seafood Crepes with Béchamel Sauce and Gruyère Recipe

Step 1: Whisk Together the Crepe Batter Smoothly

Start by combining eggs, melted butter, flour, a pinch of salt, milk, and water in a large bowl. I usually use a handheld mixer so the batter ends up silky smooth and lump-free, which helps make those crepes thin and delicate. Then, cover and let the batter rest for about 30 minutes—this little pause allows the flour to absorb the liquids fully and helps prevent tears when cooking.

Step 2: Cook Crepes with Care

Heat your non-stick pan over medium heat and lightly grease it with butter. Pour a ladle of batter and swirl it quickly in the pan to make a thin layer. Once the edges start to lift and little bubbles form on the surface (about 1 minute), it’s time to flip! Cook the other side for about 30 seconds, then stack the crepes on a plate and cover with a towel to keep them soft and warm. You’ll end up with around 10-12 crepes—enough to impress your guests.

Step 3: Craft the Silky Béchamel Sauce

Melt butter in a saucepan over medium heat—watch closely to keep it from browning. Stir in flour until you get a thick paste, then slowly add milk while whisking to avoid lumps. Bring to a gentle boil while stirring constantly until the sauce thickens nicely. Season with salt and pepper once it’s velvety smooth. Setting this béchamel aside is a good time for that coffee break or to tidy up your prep area.

Step 4: Sauté the Seafood Filling

Pat your shrimp and scallops dry—this helps them sear instead of steaming. In a skillet, cook diced onions in olive oil until translucent, then add mushrooms and cook until their moisture evaporates. Toss in the seafood and cook briefly to avoid overcooking. Splash in white wine, letting it mostly evaporate to concentrate the flavors. If there’s too much liquid, drain it off so the filling isn’t soggy. Lastly, stir in most of the béchamel (saving some for the topping) and parsley for freshness.

Step 5: Assemble and Bake Your Crepes

Butter your baking dish well to prevent sticking. Spoon about ¼ cup of the seafood filling onto the lower third of each crepe, then roll it up tightly and place seam side down in the dish. Once all crepes are nestled in, drizzle the remaining béchamel over the top and scatter shredded Gruyère evenly. Bake at 400°F for 12-15 minutes until bubbling. For an extra touch, switch on the broiler for 1-2 minutes to get that perfect golden crust. Serve these hot and watch smiles bloom around your table!

How to Serve Seafood Crepes with Béchamel Sauce and Gruyère Recipe

Garnishes

I usually sprinkle a bit of fresh parsley or chives on top before serving to add a lovely splash of green and fresh flavors that brighten up each bite. A wedge of lemon on the side really brings out the seafood’s natural brightness, too—don’t skip it if you enjoy a bit of citrus zing.

Side Dishes

Light, refreshing sides work best here. I’m a big fan of simple mixed greens dressed with lemon vinaigrette or roasted asparagus drizzled with olive oil and a pinch of sea salt. If you want something a little heartier, a garlic mashed potato or herbed rice pilaf pairs wonderfully without stealing the spotlight.

Creative Ways to Present

For special gatherings, I love baking the crepes in individual au gratin ramekins instead of one big dish—that makes serving a breeze and adds a bit of elegance to the table. You can also play with layering, stacking crepes like mini lasagnas for a dramatic centerpiece that’s both beautiful and indulgent.

Make Ahead and Storage

Storing Leftovers

When I’ve got leftovers, I cover them well with foil or plastic wrap and store in the fridge for up to 2 days. The flavors actually meld beautifully overnight, so sometimes I find the next day’s crepes taste even better!

Freezing

If I need to prep well in advance, I freeze cooked crepes wrapped tightly in plastic wrap, stacking them between sheets of parchment paper. They’ll keep for up to a month in the freezer. The filling and sauce freeze well too if stored separately in airtight containers.

Reheating

To reheat, I pop the assembled crepes in a preheated 350°F oven until warmed through and bubbly, about 15 minutes. This keeps the crepes delicate and stops the seafood from drying out. Avoid microwaving as it can make crepes rubbery.
