ingredients
- 1/2 tablespoon olive oil
- 6 skinless chicken thighs,
- 1/2 cup white wine
- 1 1/2 cup chicken stock
- 1 Vidalia onion, sliced
- 3 cloves garlic, sliced
- 2 cup green beans, blanched
- 1 tablespoon butter
- 2 russet potatoes, boiled and sliced
- 2 sprigs thyme
- 1/2 cup heavy cream
- 1 teaspoon cornstarch
- 3 ounces gruyere, grated
- 2 ounces Parmesan, grated
- 2 tablespoons French's crispy onions
- Kosher salt and pepper, to taste
Method
Step 1
Preheat oven to 400°F.
Step 2
In a hot cast iron skillet, season chicken with salt and pepper and sear in olive oil allowing to brown on both sides. After browned, add 1 cup chicken stock, white wine, half of the Vidalia onion and 1 garlic clove.
Step 3
Cover the pan with the lid halfway and allow chicken to cook through while simultaneously allowing liquid to reduce the volume by half, about 20 minutes.
Step 4
In a separate medium skillet, heat cream and the remaining chicken stock, pre-cooked potato, thyme and cornstarch and allow to thicken for 10-15 minutes at a simmer. Add 2 ounces of gruyere and 2 ounces Parmesan, salt and pepper. Ensure cheese is melted and turn off the heat.
Step 5
After the chicken is fully cooked, remove chicken from pan, reserve sauce and separate chicken from bone. Add sauce and de-boned chicken to base of cast iron, forming a bottom layer.
Step 6
In sauté medium pan, season and sear mushrooms in butter, add green beans, deglaze with 2 tablespoons of white wine. Then, layer green bean mushroom mixture on top of chicken in cast iron pan.
Step 7
Layer potatoes on top of green beans and cook in oven for 15 minutes. Next, add the remaining gruyere and cook for another 10 minutes.
Step 8
Remove from oven, allow to rest for 5 minutes, then top with crispy shallots and serve.
