Step‑by‑Step Instructions for Creamy French Chicken Casserole
Step 1: Prepare Chicken
Begin by cutting the boneless skinless chicken thighs into bite-sized pieces and seasoning with salt and pepper. This simple step flavors the chicken, ensuring each piece absorbs the deliciousness of the creamy sauce. Set the seasoned chicken aside as you get ready to brown it, which will take just a few moments.
Step 2: Brown Chicken
Heat a tablespoon of olive oil in a large skillet over medium-high heat. Add the seasoned chicken pieces, cooking them for about 5-7 minutes until they are golden brown and cooked through. Stir occasionally for even browning. Once done, remove the browned chicken from the skillet and set it aside, allowing the skillet to retain its flavorful drippings.
Step 3: Sauté Vegetables
In the same skillet, add the chopped onion and sauté for roughly 3-4 minutes until it becomes translucent and fragrant. Next, stir in the minced garlic, cooking for an additional minute to release its aromatic qualities. Now, toss in the mushrooms, carrots, and green beans, allowing everything to cook together for about 5 minutes until the vegetables start to soften, enlivening your kitchen with vibrant scents.
Step 4: Make Creamy Sauce
Stir in the dried thyme and rosemary, followed by the chicken broth and heavy cream to form the luscious base of the creamy French chicken casserole. Add the Dijon mustard and season the mixture with salt and pepper. Bring the sauce to a gentle simmer, watching for bubbles to appear as it thickens slightly, about 5 minutes.
Step 5: Combine Ingredients
Return the browned chicken back to the skillet, ensuring every piece is well-coated in the creamy sauce and mixed thoroughly with the sautéed vegetables. This combination will create a mouthwatering blend for your casserole. Generously sprinkle shredded Gruyère cheese on top, ready to melt into a bubbling delight.
Step 6: Bake
Preheat your oven to 375°F (190°C) as you prepare to finish off the creamy French chicken casserole. Transfer the skillet to the oven and bake for 25-30 minutes, or until the cheese is golden brown and bubbly. Keep an eye on it; the perfect bubbling cheese will be your cue that it’s ready!
Step 7: Let Rest
After baking, remove the casserole from the oven and allow it to rest for about 5-10 minutes before serving. This resting time helps the casserole set, making it easier to serve while enhancing the dish’s flavors. As you wait, enjoy the delightful aroma wafting through your kitchen, setting the stage for a cozy family meal.

Creamy French Chicken Casserole Recipe FAQs
What type of chicken should I use for this casserole?
I recommend using boneless skinless chicken thighs, as they provide tenderness and an incredible flavor. However, if you’re looking for a leaner option, you can always substitute them with chicken breasts or even turkey for a different twist.
How should I store leftover casserole?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, reheat gently in the microwave or oven until warm throughout.
Can I freeze the Creamy French Chicken Casserole?
Absolutely! You can freeze this casserole for up to 2 months. Just let it cool completely once it’s cooked, then wrap it tightly in plastic wrap and place it in a freezer bag. When you’re ready to enjoy it, thaw it in the refrigerator overnight, and reheat to an internal temperature of 165°F (75°C).
What if I don’t have heavy cream?
If you’re out of heavy cream, you can use half-and-half or even low-fat milk as a substitute. The sauce might be slightly less rich, but it will still be creamy and delicious! If you want to make a lighter version, you could also mix in some chicken broth to balance it out.
How do I prevent my casserole from becoming too watery?
To prevent a watery casserole, ensure that you sauté the vegetables properly before adding them to the sauce. This step helps evaporate some of the moisture. If you do find it a bit runny, you can simmer the sauce longer to allow it to thicken before adding back the chicken and veggies.
