An incredibly tasty and versatile creamy chicken casserole made from onions, carrots, celery, chicken breast and peas cooked in a creamy sauce. Serve with mashed potato, or, top with puff pastry and bake as a pie.
Here it is! The recipe for my new Creamy Chicken Casserole. A comforting and filling meal made from affordable, everyday ingredients. This is a generous-sized casserole which can be served two different ways if you like. I served half of mine with mashed potato for dinner one night. Then put the remainder in a pie dish, added some puff pastry and baked it for dinner the following night. Too easy!
To create this recipe, I worked with my favourite supermarket, Countdown. This recipe is made with carrots, celery, onions and frozen peas. I know my local Countdown will always have these simple ingredients in stock, and at an affordable price point. If value for money is on your radar, this type of meal is an excellent way to save time, energy and ingredients. Make one tasty meal and serve it two ways over two days. Who doesn't love getting ahead?
- Chicken: I used chicken breast in this recipe. Breasts are more affordable than thighs and although they can dry out in some recipes, that's not an issue here as they cook in the creamy sauce.
- Vegetables: At the base of this recipe is the Golden Trio as it is referred to in French cooking; onion, carrot and celery.
- Stock: I used liquid, store bought stock for convenience. Feel free to use homemade stock, or stock cubes and boiling water.

Step by step instructions:
Preheat the oven to 180°C fan bake. Heat a large cast-iron casserole dish to a medium heat. Pour in the oil, then add the onion, carrot and celery. Sauté for five minutes until the onion starts to soften.
Stir in the crushed garlic, then make a gap in the centre and add the butter. Once it starts to bubble, sprinkle over the flour, and stir to combine. Cook for two minutes.
Pour in half of the chicken stock and deglaze the base of the dish with a wooden spoon. Add the rest of the chicken stock, then add the diced chicken thighs.
Place the lid on top and bake in the oven for 45 minutes.
Remove the dish from the oven and add the peas and cream. Mix the cornflour with 3 tablespoons of cold water, then add to the dish and stir everything together.
Cook for another 15 minutes in the oven, uncovered, until the casserole starts to thicken up. Season well to taste with salt and pepper. Serve on top of mashed potato and garnish with parsley.
Top tip: This tasty chicken casserole can also be served as a pot pie. I like to use the leftovers for this part.
Simply add the cooled casserole to a pie dish. Place a piece of puff pastry on top and brush with an egg wash. Bake at 190°C for 40 minutes, or until the pastry is golden brown.
Either make one large pie as above, or, individual pot pies pies.
Yes it can. Simply swap the regular flour for gluten free flour. As always, make sure you read the labels on any processed food including your chicken stock to ensure it is 100% gluten free.
Absolutely. Simply allow the casserole to cool to room temperature. Place in an airtight container in the freezer for up to three months. If you want to freeze a chicken casserole pie, simply do this after the pastry has been added, but before baking. Cover well with cling film and tin foil then freeze for up to three months. Allow the pie to defrost completely before cooking as per the instructions above.
Feel free to substitute the vegetables to suit your tastes. The ones I've used are generally some of the most affordable and available all year around. Don't forget about frozen vegetables either - they are just as nutritious as fresh vegetables!
Store any leftover chicken casserole in an airtight container in the fridge for up to three days. Reheat on the stovetop or in the microwave until piping hot.
This casserole can also be frozen. Check out the handy tips in the FAQ section above.
The best thing about this meal is its versatility. The casserole can be served with a side of mashed potato, baked potatoes, steamed rice or freshly cooked pasta. Or, follow the instructions above to make a pot pie. Pot pies are generally not as thick as a regular pie and therefore don't have the extra pastry on the bottom.
AD – Thank you so much to Countdown for partnering with me to create this recipe.
