Why This Recipe Works

The secret to this casserole's success lies in the combination of flavors and textures. The crepes provide a delicate and tender base, while the chicken and mushrooms add protein and earthy flavor. The sauce, made with a mixture of cream, cheese, and spices, brings everything together and adds a rich and creamy element to the dish.

The key to making this sauce is to cook it slowly and patiently, allowing the flavors to meld together and the cream to thicken. You'll also need to stir the sauce constantly to prevent it from sticking to the bottom of the pan.

Another important aspect of this recipe is the layering of the ingredients. By placing the crepes, chicken, and mushrooms in a specific order, you'll create a dish that's both visually appealing and easy to serve.

How to Make Chicken And Mushroom Crepes Casserole

1
In a large bowl, whisk together the crepe flour, eggs, milk, and a pinch of salt. The batter should be smooth and free of lumps.
2
Heat a small non-stick pan over medium heat and brush it with a small amount of butter. Pour a small amount of the crepe batter into the pan and tilt the pan to evenly coat the bottom.
3
Cook the crepe for about 2 minutes, until the bottom is light brown. Loosen the crepe with a spatula and flip it over. Cook for another minute, until the other side is also light brown. Repeat with the remaining batter, until you have about 8-10 crepes.
4
In a large skillet, heat the olive oil over medium-high heat. Add the sliced mushrooms and cook until they are tender and lightly browned, about 5-7 minutes.
5
Add the chicken to the skillet and cook until it is browned on all sides and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set it aside.
6
In the same skillet, add the butter and let it melt. Add the flour and whisk to combine. Cook for about 1 minute, until the mixture is lightly browned and has a nutty aroma.
7
Slowly pour in the heavy cream, whisking constantly to prevent lumps. Bring the mixture to a simmer and cook until it thickens, about 2-3 minutes.
8
Add the grated cheese to the sauce and stir until it is melted and smooth. Season the sauce with thyme, salt, and pepper to taste.
9
To assemble the casserole, place a layer of crepes in the bottom of a 9x13 inch baking dish. Top the crepes with a layer of chicken, then a layer of mushrooms, and finally a layer of sauce. Repeat this process until all of the ingredients have been used, ending with a layer of sauce on top.
10
Cover the dish with aluminum foil and bake in a preheated oven at 375 F (190 C) for about 25-30 minutes, until the casserole is hot and the sauce is bubbly.
11
Remove the foil and continue baking for an additional 10-15 minutes, until the top is lightly browned and the casserole is heated through. Check the internal temperature of the chicken with an instant-read thermometer to ensure it reaches 165 F (74 C).
12
Remove the casserole from the oven and let it rest for about 10-15 minutes before serving. This will allow the sauce to set and the flavors to meld together.

Expert Tips

Make sure to cook the crepes until they are lightly browned and tender, as this will help them to hold their shape in the casserole.
Don't overfill the casserole with too many ingredients, as this can make it difficult to serve and can lead to a messy presentation.
