Ingredients

2 tbsp olive oil
8 bone-in, skin-on chicken thighs (or 4 large chicken breasts, cut into 2-3 pieces each)
2 large onions, chopped
3 carrots, peeled and thickly sliced
3 celery sticks, thickly sliced
200g button mushrooms, halved
2 large leeks, trimmed and thickly sliced
2 cloves garlic, crushed
1 tbsp plain flour
500ml chicken stock (good quality)
150ml dry white wine (optional, but highly recommended for depth of flavour)
2 tbsp fresh parsley, chopped
1 tbsp fresh thyme leaves
1 bay leaf
Salt and freshly ground black pepper

Equipment Needed

Large ovenproof casserole dish with a lid (or a large heavy-based pan and a separate ovenproof dish) • Large chopping board • Sharp knife • Measuring jug • Wooden spoon or spatula

Step-by-Step Instructions

Preheat your oven to 180°C (160°C fan/Gas Mark 4).
Heat the olive oil in a large, ovenproof casserole dish or heavy-based pan over a medium-high heat. Season the chicken thighs generously with salt and pepper. Brown the chicken pieces in batches until golden all over, then remove and set aside. This step is crucial for flavour!
Add the chopped onions, carrots, and celery to the same pan. Cook gently for about 8-10 minutes until softened, scraping up any delicious browned bits from the bottom of the pan.
Stir in the mushrooms, leeks, and crushed garlic. Cook for another 5 minutes until the leeks begin to soften.
Sprinkle the plain flour over the vegetables and stir well, cooking for 1-2 minutes to cook out the raw flour taste.
Gradually pour in the chicken stock and white wine (if using), stirring continuously to prevent lumps and create a smooth sauce. Bring to a gentle simmer.
Return the browned chicken pieces to the casserole dish, nestling them amongst the vegetables. Add the fresh parsley, thyme, and bay leaf. Season with a little more salt and plenty of freshly ground black pepper.
Bring the casserole back to a gentle simmer on the hob, then cover with a lid and transfer to the preheated oven.
Bake for 1 hour to 1 hour 15 minutes, or until the chicken is wonderfully tender and cooked through, and the sauce has thickened beautifully.
Remove the bay leaf before serving. Taste and adjust seasoning if necessary. Serve piping hot with your favourite accompaniments.

Perfect Substitutions

Chicken: Boneless, skinless chicken thighs or breasts can be used, but adjust cooking time as they will cook quicker. Brown them well for flavour.
Vegetables: Feel free to add other root vegetables like parsnips or swede, or even some frozen peas towards the end of cooking.
Wine: If you prefer not to use wine, simply increase the chicken stock by the same amount. A splash of cider would also work beautifully.
Herbs: Dried mixed herbs can be used in place of fresh, but use a little less (e.g., 1 tsp dried thyme).

Serving Suggestions

This delightful casserole is wonderfully versatile. I love to serve it with creamy mashed potatoes, perhaps a little buttered new potatoes, or even some fluffy rice to soak up all that glorious sauce. A side of lightly steamed green vegetables, such as tenderstem broccoli or green beans, would complete this truly wholesome meal beautifully.

How to Store \u0026 Reheat

Allow the casserole to cool completely before transferring it to an airtight container. It will keep beautifully in the refrigerator for up to 3 days. To reheat, gently warm on the hob over a low heat, stirring occasionally, until piping hot throughout. You may need to add a splash more stock or water if the sauce has thickened too much. This casserole also freezes exceptionally well for up to 3 months. Thaw thoroughly in the refrigerator overnight before reheating as above.

Mary's Secrets to Success

Browning the Chicken: Don't skip this step! Browning the chicken pieces well before adding them to the casserole creates a beautiful depth of flavour that you simply won't achieve otherwise. It's the secret to a truly rich sauce. Layering Flavours: Take your time to sauté the vegetables properly. Each stage of cooking builds flavour, from softening the onions to cooking out the flour. Patience here will be greatly rewarded. Good Quality Stock: A really good quality chicken stock makes all the difference. It forms the backbone of your sauce, so choose one that is rich and flavourful. Resting: Allow the casserole to rest for 5-10 minutes after it comes out of the oven before serving. This allows the flavours to settle and the sauce to thicken slightly.

Frequently Asked Questions

Can I use boneless, skinless chicken?

Yes, absolutely! While bone-in, skin-on thighs add wonderful flavour and keep the meat moist, boneless cuts are perfectly fine. Just ensure they are browned well initially and check for tenderness a little earlier in the cooking process, as they tend to cook more quickly.

How can I thicken the sauce more?

If you find your sauce isn't quite as thick as you'd like, you can either remove the lid for the last 15-20 minutes of cooking to allow some liquid to evaporate, or you can stir in a small amount of a cornflour (cornstarch) slurry (1 tsp cornflour mixed with 1 tbsp cold water) towards the end, simmering for a few minutes until it thickens.

Can I make this ahead of time?

Indeed, this casserole is an ideal make-ahead dish! The flavours actually deepen and improve overnight, making it even more delicious the next day. Simply cook as directed, allow to cool, then refrigerate. Reheat gently until piping hot throughout.

What if I don't have an ovenproof casserole dish?

Not to worry! You can do all the initial browning and sautéing on the hob in a large, heavy-based pan. Once you've added the stock and returned the chicken, simply transfer the entire contents to a deep ovenproof dish, cover it tightly with foil, and bake as instructed.

Can I add other herbs?

Certainly! Rosemary or bay leaves (if not already used) would be lovely additions, offering a slightly different aromatic note. A sprig of fresh sage could also be wonderful, particularly if you're using white wine. Always taste and adjust to your preference.
