Whether you’re cooking for your family or hosting a small gathering, this casserole is always a hit. Let’s get started on this simple yet amazing dish.

Ingredients You’ll Need

Here’s everything you need to whip up this casserole. Most of these are pantry staples, so you might already have them on hand:

• 6 chicken thighs (bone-in, skin-on for extra flavor)
• 2 tablespoons olive oil
• 1 onion, finely chopped
• 2 garlic cloves, minced
• 1 cup mushrooms, sliced
• 1 cup chicken stock
• 1/2 cup white wine (optional, but highly recommended!)
• 1/2 cup heavy cream
• 1 tablespoon Dijon mustard
• 1 teaspoon dried thyme (or 2 teaspoons fresh thyme)
• Salt and pepper to taste
• Fresh parsley for garnish

How to Make French Chicken Casserole

Step 1: Prep Your Ingredients

First things first, gather all your ingredients. I like to chop everything ahead of time so I can focus on cooking. Trust me, this little step makes things feel way more manageable.

Step 2: Sear the Chicken

Heat the olive oil in a large oven-safe skillet over medium heat. Season your chicken thighs with salt and pepper, then sear them skin-side down until they’re golden brown. This usually takes about 5 minutes. Flip them over and cook for another 3 minutes. Once done, set the chicken aside.

Step 3: Sauté the Vegetables

In the same skillet, add the chopped onion and cook until it’s softened and slightly golden. Toss in the garlic and mushrooms, and cook for another 3-4 minutes. Your kitchen will smell amazing by now!

Step 4: Build the Sauce

Pour in the white wine to deglaze the pan, scraping up all those flavorful bits stuck to the bottom. Let it simmer for a minute or two, then add the chicken stock, cream, Dijon mustard, and thyme. Stir it all together and bring it to a gentle simmer.

Step 5: Combine and Cook

Nestle the chicken thighs back into the skillet, making sure they’re coated in the sauce. Transfer the skillet to a preheated oven at 375°F (190°C) and bake for 25-30 minutes, or until the chicken is fully cooked and tender.

Step 6: Garnish and Serve

Once out of the oven, sprinkle fresh parsley over the top for a pop of color. Serve the casserole straight from the skillet alongside some crusty bread, mashed potatoes, or a fresh salad.

Tips for Making the Best French Chicken Casserole

• Use quality chicken. Bone-in, skin-on thighs really elevate the flavor, but you can use chicken breasts if you prefer.
• Don’t skip the searing. It adds depth to the dish and keeps the chicken juicy.
• Make it your own. Swap out the mushrooms for leeks or add some carrots for extra veggies.

What to Serve with French Chicken Casserole

This casserole is versatile and pairs beautifully with sides like:

• Creamy mashed potatoes
• Buttered noodles
• Steamed green beans
• A simple green salad

Storing and Reheating Leftovers

If you’re lucky enough to have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of stock or cream to revive the sauce.
