Ingredients:
- 1 cup (125g) all-purpose flour
- 1/4 teaspoon salt
- 1 large egg
- 1 1/4 cups (300ml) milk
- 2 tablespoons (30g) unsalted butter, melted, plus more for greasing the pan
- 2 tablespoons (30g) unsalted butter
- 1/2 cup (75g) chopped yellow onion
- 2 cloves garlic, minced
- 10 ounces (300g) fresh spinach, roughly chopped
- 1 1/2 cups (200g) cooked chicken, shredded or diced
- 1/2 cup (120ml) heavy cream
- 1/4 cup (30g) grated Parmesan cheese, plus more for topping
- Salt and freshly ground black pepper to taste
- 2 tablespoons (30g) unsalted butter
- 2 tablespoons (15g) all-purpose flour
- 1 1/2 cups (360ml) milk
- 1/4 teaspoon salt
- 1/4 teaspoon ground nutmeg
- 1/2 cup (60g) grated Gruyere cheese
- 1/4 cup (30g) grated Parmesan cheese
Instructions:
- Make the Crêpe Batter: Blend or whisk together flour, salt, egg, milk, and melted butter. Let rest for at least 30 minutes.
- Cook the Crêpes: Heat a lightly greased crêpe pan or skillet over medium heat. Pour a thin layer of batter onto the pan, swirling to coat. Cook for 1-2 minutes per side, until golden brown. Repeat until all batter is used.
- Prepare the Filling: Melt butter in a large skillet. Sauté onion and garlic until softened. Add spinach and cook until wilted. Stir in chicken, heavy cream, Parmesan cheese, salt, and pepper. Simmer until heated through.
- Make the Mornay Sauce: Melt butter in a saucepan. Whisk in flour and cook for 1 minute. Gradually whisk in milk until smooth. Bring to a simmer, then reduce heat and cook until thickened. Stir in salt, nutmeg, Gruyere cheese, and Parmesan cheese until melted.
- Assemble and Bake: Spoon chicken filling into the center of each crêpe. Roll up the crêpes and place them seam-side down in a greased baking dish. Pour Mornay sauce over the crêpes and sprinkle with Parmesan cheese. Bake at 375°F (190°C) for 20-25 minutes, or until golden brown and bubbly.
