Ingredients
  

For the Crêpes:

  • 1 cup all-purpose flour
  • 2 large eggs
  • 1 ¼ cups milk
  • 2 tbsp melted butter
  • Pinch of salt

For the Seafood Filling:

  • 1 tbsp olive oil or butter
  • ½ small onion, finely chopped
  • 1 garlic clove, minced
  • 1 cup cooked shrimp, chopped
  • 1 cup cooked scallops or white fish, flaked
  • ½ cup cooked crab meat (optional)
  • ½ cup mushrooms, finely chopped
  • Salt and pepper, to taste
  • 2 tbsp parsley or chives, chopped

For the Béchamel Sauce:

  • 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 1 ½ cups milk
  • Salt, white pepper, and a pinch of nutmeg
  • ¼ cup grated Parmesan or Gruyère (optional)

Instructions
 

  • 1. Make the Crêpe Batter:
    Whisk together flour, eggs, milk, melted butter, and salt until smooth. Let rest 30 minutes (optional for tenderness).
  • 2. Cook the Crêpes:
    Heat a non-stick pan, lightly greased. Pour in about ¼ cup of batter, swirl to coat, and cook until golden on both sides. Set aside.
  • 3. Prepare the Filling:
    Sauté onions and garlic in olive oil until soft. Add mushrooms, then seafood. Cook briefly, season with salt, pepper, and herbs.
  • 4. Make the Béchamel:
    Melt butter, whisk in flour, and cook for 1 minute. Gradually add milk, whisking until smooth. Season with salt, pepper, and nutmeg. Stir in cheese if using.
  • 5. Assemble the Crêpes:
    Place filling in each crêpe, roll or fold, and place in a baking dish. Pour béchamel over the top.
  • 6. Optional – Bake:
    Bake at 375°F (190°C) for 10–15 minutes until bubbly and slightly golden.

Notes

  • Use Fresh or Frozen Seafood: Be sure to pat seafood dry before cooking to avoid excess moisture that can make the crêpes soggy.
  • Make Ahead Tip: Both the crêpes and béchamel sauce can be made a day in advance. Store them separately in the fridge, then assemble and bake just before serving.
  • Crêpe Texture Matters: Don’t overcook the crêpes—they should be tender and pliable, not crispy, so they can roll easily without tearing.
  • Thicken the Béchamel: Let the béchamel simmer until it coats the back of a spoon. A thick sauce prevents runny fillings.
  • Customize the Filling: Add sautéed leeks, mushrooms, or spinach for extra flavor and nutrition.
  • Garnish Ideas: Top with fresh parsley, chives, a sprinkle of parmesan, or a squeeze of lemon for brightness.
