Step‑by‑Step Instructions for Chicken Casserole Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 190°C (170°C fan/Gas 5). This ensures the temperature is just right when your Chicken Casserole is ready to bake. A hot oven helps to create that golden, bubbly finish we all love. While the oven heats up, gather all your ingredients to streamline the cooking process.
Step 2: Season the Chicken
While the oven is warming, take your bone-in, skin-on chicken thighs and season them generously with salt and pepper. This simple step enhances the flavor of the chicken, bringing out its natural juices. Make sure to coat both sides of the thighs for a well-seasoned dish that will delight your family.
Step 3: Sear the Chicken
In a large non-stick casserole pan, heat a splash of olive or sunflower oil over medium-high heat. Once hot, carefully add the seasoned chicken thighs skin-side down and sear for 7-8 minutes until the skin is beautifully golden brown. Afterward, turn them over and cook for an additional 3 minutes before removing them from the pan to set aside.
Step 4: Sauté the Vegetables
In the same pan, add the sliced onion, chopped bacon, and mushrooms. Sauté for 4-5 minutes until the onion is soft and everything is lightly browned. This will infuse your Chicken Casserole with a rich, smoky flavor, creating a perfect base for the dish ahead. Stir occasionally to ensure even cooking and to scrape up any browned bits from the bottom.
Step 5: Add Carrots and Flour
Next, toss in the sliced carrots and sprinkle over the plain flour. Stir everything together well to coat the vegetables with flour, which will help thicken the sauce later. Cook this mixture for about 2-3 minutes until everything is well mixed and starting to soften, creating a flavorful foundation for your casserole.
Step 6: Incorporate the Stock and Thyme
Sprinkle dried thyme over the mixture, then gradually pour in the hot chicken stock while continuously stirring. This will help you avoid lumps and ensure a smooth sauce for your Chicken Casserole. Bring this to a simmer, allowing the mixture to thicken slightly as the flavors meld together, creating a heavenly aroma in your kitchen.
Step 7: Return Chicken to the Pan
Now, return the seared chicken thighs to the pan, nestling them into the bubbling sauce. Bring the entire mixture back to a simmer, then cover the pan with a lid. This will trap the moisture, helping the chicken to cook evenly and retain its juiciness. Once simmering well, transfer the casserole gently into the preheated oven.
Step 8: Bake the Casserole
Let your Chicken Casserole bake in the oven for 45 minutes. You’ll know it’s ready when the chicken is cooked through and tender. The aroma should be irresistible! After 45 minutes, carefully remove the casserole; be cautious of the hot steam when lifting the lid.
Step 9: Add Leeks and Finish Baking
Finally, stir in the sliced leeks, which will add a lovely sweetness and texture to the dish. Cover it again and return the casserole to the oven for an additional 15 minutes. This allows the leeks to soften beautifully. When the timer goes off, the Chicken Casserole should be bubbly and inviting, perfect for serving to your loved ones.

Chicken Casserole Recipe FAQs
How do I choose the right chicken for my casserole?
Absolutely! For a flavorful and juicy Chicken Casserole, I recommend starting with bone-in, skin-on chicken thighs—they truly elevate the dish. However, if you’re short on time, boneless thighs work wonderfully and will reduce your cooking time; just remember to adjust accordingly, letting them cook for about 35 minutes before adding leeks.
How should I store the leftover chicken casserole?
Very good question! Store leftover Chicken Casserole in an airtight container in the fridge for up to 3 days. Ensure it has cooled completely before sealing to preserve the flavors. For longer storage, freeze it in a suitable container for up to 3 months. This helps keep it fresh and ready for a cozy meal anytime!
Can I freeze my chicken casserole?
Absolutely, freezing is a great option! Once the casserole has cooled completely, transfer it to an airtight container, leaving some space for expansion. You can store it for up to 3 months. To reheat, allow it to thaw overnight in the fridge, then gently warm on the stovetop, adding a splash of chicken stock to keep it moist.
What if my casserole turns out too watery?
Very common! If you find your casserole is too watery, don’t worry—just simmer it on the stovetop over low heat to reduce the liquid.
