I have a few health problems, which means there are days when I’m at home in agony. I still want to make a dinner for my family, but don’t always have lots of effort to put in. This slow cooker chicken and mushroom pie filling is PERFECT for these days!
Today I want to share with you one of my easiest recipes ever! You can use leftover wine, if you’re the type of person who has leftover wine, or stock, if you’re not. Be sure to check out my slow cooker tips while you’re here too.
It is really an absolute doddle and you can have this slow cooker chicken mushroom pie filling in your slow cooker in minutes.

Ingredients for slow cooker chicken mushroom pie filling
250ml white wine
2 tablespoons of plain flour
Salt and pepper
Stock cube or stock pot
400g chicken breast
1 tsp of thyme, tarragon or rosemary
1 tin of sliced mushrooms or 300g fresh mushrooms
20g butter
50g frozen filo pastry sheets
Method for slow cooker chicken mushroom pie filling
Whisk together 250ml of white wine, 2 tablespoons of plain flour and salt and pepper. Either whisk it in a jug, to help with measuring out the wine, or directly in to your slow cooker pot to save yourself a little effort, and washing up.

Add your chicken.

Add your mushrooms. Crumble in a stock cube or add a stock pot. Add a little thyme, tarragon or rosemary depending on your preferred flavour. I find tarragon works really well and often used dried for convenience.
Cook on low for 8+ hours. I cooked ours overnight, for 10 hours, and it was lovely and flaky.
If you want to keep larger chunks of chicken then used diced chicken and cook for 4-5 hours on low or 3 hours on high.

Pour into a pie tin. Melt your butter. Dip your filo pastry sheets in and then lay on top of the slow cooker chicken mushroom pie filling.
Cook at gas mark 5 (190C) for 25-30 minutes. As soon as the top is golden brown it is ready for serving.

ALL of the slow cooker recipes on this website have been cooked using a Ninja Foodi OL750UK, or a previous Ninja multi-cooker model, but you can use ANY slow cooker, as timings should be very similar.

Loved it, the only thing is I’d of liked the sauce a bit thicker so I think next time I’ll use a little less wine.

This sounds/looks delicious! Laughing at "if you're the type of person who has leftover wine" I'm definitely not that person! X
