There’s something timeless about French Chicken Casserole — that mix of elegance and simplicity that French country cooking does so well. Juicy chicken thighs are seared until golden, then simmered slowly with mushrooms, shallots, herbs, and a splash of white wine until the sauce turns silky and rich.
It’s a comforting, aromatic dish that feels like a hug in a pot — perfect for cold evenings or when you want to impress without fuss.

Every ingredient adds a layer of flavor — the herbs bring freshness, the wine adds depth, and the cream ties it all together.
Main Ingredients

- 8 ounces cremini mushrooms, halved

- 2 ribs celery, diced
- 3 cloves garlic, minced
- 3 tablespoons all-purpose flour
- 2 cups chicken stock
- 1 pound baby gold potatoes, halved
- 4 sprigs fresh thyme
- 1 sprig fresh rosemary
- 1 bay leaf
- ¼ cup heavy cream
Optional Add-Ons or Substitutes
- Use boneless thighs or chicken breasts for a leaner version

Step-by-Step Instructions
This casserole is all about layers — browning, simmering, and letting the sauce evolve into something magical.
- Prep and season the chicken: Pat the chicken thighs dry and season generously with salt and pepper. (Jake’s tip: Dry skin = better sear.)
- Sear the chicken: In a large Dutch oven, melt butter over medium-high heat. Add the chicken, skin-side down, and sear for 4–5 minutes per side until golden brown. Remove and set aside.
- Cook the vegetables: In the same pot, add mushrooms, shallots, and celery. Sauté for 5 minutes until softened and slightly caramelized.
- Add garlic and flour: Stir in minced garlic and cook for 30 seconds. Sprinkle flour and stir well to form a roux, letting it coat the vegetables.
- Deglaze: Pour in the white wine, scraping up all the browned bits at the bottom — that’s where the flavor lives. Simmer for 2 minutes.
- Add stock and herbs: Stir in chicken stock, thyme, rosemary, and bay leaf. Add potatoes and return the chicken to the pot, nestling it into the broth.
- Simmer: Cover and reduce heat to low. Cook for 35–40 minutes, until the chicken is tender and potatoes are fork-soft.
- Finish with cream: Stir in the heavy cream. Simmer uncovered for another 5 minutes to thicken slightly.
Quick Reminders:
- Always brown your chicken first — that’s non-negotiable for depth of flavor.
- Don’t rush the simmer — slow heat makes the sauce luscious.
- Remove herbs before serving to keep the sauce smooth.
- Serve immediately while the sauce is velvety and aromatic.
Expert Tips for Success
This dish is simple but benefits from small chef’s touches.
- Use bone-in chicken for the juiciest texture.
- Deglaze properly to lift all the caramelized flavor.
- Add a splash of lemon juice at the end for brightness.
- Don’t over-stir the potatoes — they’ll thicken the sauce naturally.
- Fresh herbs matter — they give a more aromatic finish.
- Pair with crusty bread or rice to soak up every drop.
