Here's my version:
4 skinless chicken quarters
1 cup of your favorite grated cheese ( I used gruyere)
1/3 cup mayo
1/3 cup sour cream
Salt + pepper
2 tbsp olive oil
Season skinless chicken quarters with salt and pepper. Place on a baking sheet.
Slice onions on a mandolin and mix with a tbsp of oil. Sprinkle on the chicken. Slice potatoes on a mandolin, season with salt and 1 tbsp of olive oil. Arrange potatoes atop the chicken with some overlap. Bake at 385F for 25 minutes. Mix sour cream, mayo and cheese with smoked paprika. Remove the chicken from the oven and spread the cheese mix atop potatoes. Return to oven for 10 minutes. After 10 minutes raise the temp to 425 and watch for the cheese to turn a nice caramel color. Once it does, your "French" chicken is ready to remove from the oven and serve.
