Ingredients for Mary Berry Chicken Casserole Recipe
- 8 skinless, boneless chicken thighs, cut into large bite-sized chunks
- 6 ounces smoked back bacon, chopped into small salty pieces
- 2 large leeks, cleaned and sliced into thick rounds
- 3 medium carrots, peeled and sliced into chunky circles
- ½ pound baby button mushrooms, left whole for a rustic look
- 2 tablespoons all-purpose flour to thicken the savory sauce
- 2 cups chicken stock, low sodium to keep it healthy
- ½ cup dry white wine (optional, use more stock if preferred)

- 1 teaspoon dried thyme or a few fresh sprigs
- 2 tablespoons sunflower oil for frying the meat
- Salt and black pepper to taste for perfect seasoning
- Fresh parsley, finely chopped for a bright green garnish
Instructions for Mary Berry Chicken Casserole Recipe
1. Brown the Chicken
Heat the oil in a large frying pan over a medium-high heat on your stove. Add the chicken chunks and cook until they are golden brown on all sides for better flavor.
2. Crisp the Bacon
Remove the chicken and add the chopped bacon to the same hot frying pan. Cook the bacon until it is crispy and has released its smoky, savory fat into the pan.
3. Sauté the Vegetables
Add the sliced leeks and carrots to the pan with the bacon and cook for five minutes. The vegetables will soften and absorb all the wonderful flavors from the bacon and the chicken.
4. Stir in Flour
Sprinkle the all-purpose flour over the vegetable and bacon mixture and stir it in very well. Cook for two minutes to remove the raw flour taste and create a thick base.
5. Add the Liquids
Slowly pour in the chicken stock and white wine while stirring constantly to avoid any lumps. Bring the liquid to a gentle simmer until the sauce begins to thicken and look glossy.
6. Combine in Dish
Transfer the chicken pieces and the vegetable sauce into your large ovenproof casserole dish. Make sure the chicken is well-covered by the liquid so it stays very moist and tender.
7. Season and Herb
Stir in the Dijon mustard, dried thyme, salt, and pepper until everything is perfectly combined. The mustard adds a secret layer of flavor that makes the casserole taste professional and rich.
8. Add the Mushrooms
Place the whole button mushrooms on top of the mixture and push them down into the sauce. Mushrooms add an earthy taste and a wonderful texture to every bite of the finished dish.
9. Bake in Oven
Cover the dish with a tight lid and bake at 325°F for about one hour. The long, slow cooking time allows the chicken to become incredibly soft and the sauce to intensify.
10. Garnish and Serve
Remove the dish from the oven and sprinkle fresh parsley over the top for a bright finish. Serve the hot casserole in deep bowls while the steam is still rising and smelling delicious.
Cooking Tips and Simple Recipe Variations
- Use chicken drumsticks or thighs with the bone in for an even richer chicken flavor.
- Swap the white wine for a splash of apple cider for a sweeter, fruity twist.
- Add a handful of frozen peas during the last ten minutes for extra color and nutrition.
- If you don’t like leeks, you can use two large yellow onions instead for the base.
- Make sure to trim any excess fat from the chicken to keep the sauce clean.
- For a thicker sauce, stir in a little cornstarch mixed with water at the very end.
Leeks are one of those underrated vegetables that truly shine when they are given time to soften slowly in a savory base.
If you have leeks left over after making this casserole, this silky, warming leek and potato soup is one of the most satisfying ways to use them up on a cold day.

FAQs about Mary Berry Chicken Casserole Recipe
Can I make this in a slow cooker?
Yes, you can! Brown the meat and veggies first, then cook on low for six to seven hours. You may need to use slightly less stock since the liquid does not evaporate.
Do I have to use white wine?
No, you do not have to use wine if you prefer not to cook with it. Simply replace the wine with an equal amount of chicken stock or even some apple juice.
Why are my carrots still hard?
Make sure to slice your carrots into thin circles so they can cook through in time. If you like very soft carrots, sauté them for a few extra minutes at the start.
Can I use chicken breast instead?
You can use chicken breast, but be careful not to overcook it as it can become dry. Thighs are recommended because they stay juicy during the long baking time in the oven.
How do I get a very thick sauce?
The flour should thicken it, but you can also mash a few of the cooked carrots. This is a natural way to add thickness and extra flavor to your savory gravy.
