How to Make French Chicken Casserole
Step 1: Prepare the Chicken
Preheat your oven to 350°F (175°C).
Pat the chicken dry with paper towels and season generously with salt and black pepper.
Lightly coat each piece with flour, shaking off any excess.
Step 2: Brown the Chicken
Heat the olive oil in a Dutch oven over medium-high heat.
Place the chicken skin-side down and cook until golden brown. Turn and brown the other side.
Transfer the chicken to a plate.
Step 3: Cook the Vegetables
Reduce the heat to medium.
Add the butter, onion, carrots, celery, and mushrooms to the same pot.
Cook for several minutes until the vegetables begin to soften.
Stir in the minced garlic and tomato paste, cooking for another minute until fragrant.
Step 4: Build the Sauce
Pour in the chicken broth while stirring to loosen any browned bits from the bottom of the pot.
Add the Dijon mustard, thyme sprigs, and bay leaves.
Mix well until everything is combined.
Step 5: Bake
Return the browned chicken to the pot, nestling it into the vegetables.
Cover with a lid and transfer to the oven.
Bake for 45–55 minutes, or until the chicken is tender and reaches a safe internal temperature.
Step 6: Finish the Dish
Remove the thyme stems and bay leaves.
Sprinkle freshly chopped parsley over the casserole before serving.
Why This Recipe Is So Flavorful
The secret to an exceptional French Chicken Casserole is layering flavors.
Browning the chicken first creates a rich base, while the vegetables caramelize slightly before the broth is added. As the casserole bakes, the herbs infuse the sauce, and the chicken becomes incredibly tender.
