Ingredients
  

For the Crêpes

  • 1 cup 125g flour
  • 2 eggs
  • 1 ½ cups milk
  • 1 tbsp melted butter
  • Pinch of salt

For the Filling

  • 2 cups cooked shredded chicken
  • 1 ½ cups sliced mushrooms
  • 1 small onion finely chopped
  • 2 tbsp butter
  • 2 tbsp olive oil
  • Salt & black pepper
  • Fresh parsley chopped

For the Béchamel Sauce

  • 3 tbsp butter
  • 3 tbsp flour
  • 2 cups milk
  • Salt pepper & nutmeg to taste

For the Topping

  • 1 –1 ½ cups shredded cheese mozzarella, gruyère, emmental, or a mix

Instructions
 

  • Prepare the Crêpes: Mix flour, eggs, milk, melted butter, and salt until smooth. Cook thin crêpes in a lightly greased pan and set aside.
  • Make the Filling: Sauté the onion and mushrooms in butter and olive oil until softened. Add the shredded chicken, season with salt, pepper, and parsley. Stir in a few tablespoons of béchamel to make the filling creamy.
  • Prepare the Béchamel: Melt butter, whisk in flour, and cook for 1 minute. Gradually pour in the milk while whisking until the sauce thickens. Season with salt, pepper, and nutmeg.
  • Assemble the Casserole: Spoon chicken-mushroom filling into each crêpe and fold. Place the filled crêpes inside a casserole dish or oven-safe skillet. Pour the remaining béchamel over the top. Add shredded cheese.
  • Bake: Bake at 375°F (190°C) for 20–25 minutes. Broil for 2–3 minutes to achieve a golden, bubbly top.

Notes

  • Smoked chicken adds a deeper, richer flavor.
  • Gruyère or mozzarella gives the best melt and browning.
 

Storage
