Instructions
Step 1: Prepare the Potato Dauphinoise
Preheat oven to 350°F.
In a saucepan, combine heavy cream, butter, smashed garlic, thyme, rosemary, salt, and pepper. Bring to a gentle simmer for 2–3 minutes, then remove from heat and allow the herbs to infuse for about 15 minutes.
Butter a baking dish and begin layering the potatoes slightly overlapping. Pour some of the infused cream over each layer as you go.
Top with Gruyère or Parmesan cheese.
Cover loosely with foil and bake for 50 minutes. Remove foil and continue baking another 20–25 minutes until golden and bubbling.
Let rest while preparing the chicken.

Step 2: Sear the Chicken
Pat chicken thighs dry and season generously with salt and pepper.
Heat butter and olive oil in a large skillet over medium-high heat.
Sear chicken skin-side down first until deeply golden and crisp, about 4–5 minutes per side.
Transfer chicken to a plate.

Step 3: Build the Sauce
In the same skillet, add onions, mushrooms, green beans, and white wine.
Cook for 8–10 minutes until mushrooms become caramelized and onions soften.
Add garlic and flour and stir continuously for 1 minute.
Pour in chicken stock while scraping all the browned bits from the bottom of the pan.
Return chicken and juices back into the skillet. Cover and simmer over medium-low heat for 10–15 minutes until chicken is cooked through and tender.

Step 4: Finish the Cream Sauce
In a bowl, whisk together sour cream and egg yolk.
Slowly whisk in a few spoonfuls of the warm sauce to temper the mixture.
Reduce heat to low and slowly stir the cream mixture back into the skillet.
Add lemon juice and parsley.
Simmer gently for 3–5 minutes until the sauce becomes silky and slightly thickened.
Taste and adjust seasoning as needed.
