2 Syn Steak and Mushroom Pie | Slimming World

Since starting on Slimming World one thing we miss is pie! Mmmmm piiiiiiiie! We came up with a Slimming World alternative, a 2 Syn Chicken and Mushroom Pie, so we thought we’d try it with steak and came up this 2 Syn Steak and Mushroom Pie!


For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

Now, we know there’s probably a lot of Slimming World friendly pies made with filo out there, but this is our version (so it’s obviously our favourite, although we’re a little bit biased perhaps?).

2 Syn Steak and Mushroom Pie


As we all know, shortcrust and puff pastry are quite high in syns. When I say quite high, I mean silly high. Filo is a good low syn alternative and you still get a nice crunchy lid. You’ll even save around half the amount of syns if you switch to filo.

The Instant Pot

What can I say about the Instant Pot? It’s like a like a slow cooker/pressure cooker hybrid, and it’s probably one of our favourite, and most used kitchen gadgets. It makes cooking this 2 Syn Steak & Mushroom Pie SO much easier. The filling will take 30 minutes in the pressure cooker compared with over 4 hours in the slow cooker!!

When ever we need to replace oil to cook things in the oven we use Frylight. Perfect for everyday frying and cooking, it delivers exactly one calorie per spray, which makes it Syn free! The Butter Flavour is perfect for this 2 Syn Steak and Mushroom Pie recipe as you would normally brush the filo with melted butter before cooking.

Pressure Cooker - Pie Filling
  1. Spray the Instant Pot/pressure cooker with frylight and place into Saute mode. Brown the steak in batches until it has browned then set aside
  2. Deglaze the pan with some of the beef stock, making sure there is nothing stuck to the bottom of the pan. Add the onions, mushrooms, red wine vinegar, Worcestershire sauce, tomato puree, stock pot (optional), and beef stock to the pan and stir well
  3. When the liquid starts to bubble add the steak & lock the lid. Place on Manual for 30 minutes. Make sure the valve on top is set to sealing & allow the Instant Pot/pressure cooker to release manually for 20 minutes after cooking
  4. Remove the lid and place the Instant Pot/pressure cooker back into Sautee mode & reduce the mixture until it reaches your desired thickness - you can also add some cornflour to thicken up if you don't wish to wait, but remember to add the syns
Slow Cooker - Pie Filling
  1. Spray a frying pan with frylight and brown the steak in batches. Place into the slow cooker
  2. Add all of the other pie filling ingredients and cook on high for 4 hours.
  3. Remove the lid and cook for a further hour & reduce the mixture until it reaches your desired thickness - you can also add some cornflour to thicken up if you don't wish to wait, but remember to add the syns
Assembling the Pie
  1. Pour the pie filling into an oven proof dish (we used a 19 cm shallow dish but you can use a smaller deeper one if you want)
  2. Take one sheet of filo, lay it out flat and spray generously with Butter Frylight
  3. Cut the sheet into 8 even pieces. Scrunch each piece up lightly then place them on top of the pie filling. Try to leave as fewer gaps as possible
  4. Spray with a little more Frylight
  5. Place the dish on a baking tray (just in case it drips) and cook for 15 - 20 minutes at 180°C or until the filo is golden brown and crisp all over
  6. Remove from the oven and serve

  1. I cooked this for tea tonight and it was divine and felt so naughty! Proper comfort food that was easy to cook and so tasty!

  2. Hello.
    Do you think it would be ok to make the pie mixture and leave it for a day or two then put the filo on and oven bake it?
    I am thinking I can use the slow cooker in an evening and then make the pie the next evening or the evening after?

    1. Hi Hells
      Yes you can make the pie filling in advance then just top it with the filo when you’re ready to cook it 🙂

  3. This looks lovely! Do you think I could use sunflower frylight instead of butter? Or wouldn’t it taste very nice?

  4. Wow wow wow….If you gave not made this then your missing out on a really fabulous pie! My husband requests this pie every week and gets excited when he lifts the lid on the slow cooker and realises that it’s the steak pie filling! Again another easy meal to make using your slow cooker. Tasty, delicious and filling….it also feels very naughty that your eating it lol! My kids love this meal to so I do t have to cook two separate meals. We cannot wait to try the chicken and mushroom pie next!

  5. Hi, I’m planning on making this, this week but was wondering what sort of temperature to set the oven at to cook the filo pastry topping on? Thank you 😄

    1. Hi Anne
      Yes, there are instructions in the recipe to make the filling in the slow cooker or Instant Pot, then transferring to a pie dish and adding the filo topping for baking in the oven. Hope this helps.

  6. Hi, I’m making this tomorrow and I just wanted to confirm the number of filo pastry sheets – surely it’s not 50 sheets for 4 people..?

    Thanks xx

    1. Hi Kathryn
      I think you are confusing sheets with grams…..the ingredients state you will need one 25g sheet of filo for 2 portions, so 4 portions would equal two 25g sheets (or 50g)

    1. Hi Paula
      You can freeze the filling without any problems, but if you want to freeze the pie you would probably have to freeze it with the raw pastry on top

  7. I’ve made this before and was amazing! Making it tomorrow for my parents but my mum doesn’t like mushrooms, any alternative suggestions? Many thanks

  8. First attempt this evening – resounding success + delicious; thank you for the recipe.
    Even looked like your picture – sorry couldn’t upload as disappeared before having a chance 😊. Would amend slightly with less liquid + definitely thicken on cooker top. Scrummy!

    1. Hi Yvonne
      Yes, the filling could be cooked in the oven. It would be best to cook it slowly and at a low temperature. Have a bit of extra stock ready to add, so that it doesn’t dry out. 🙂

  9. Hi I’ve made the chicken pie before which was lovely but ended up throwing the rest of the pastry as only needed the wrong sheet? What do you do with leftovers as it seems such a waste? I don’t know if they could be frozen separately? Thanks in advance.

  10. Made this last week and it is amazing.
    Am making another now. I swapped filo for mashed swede, carrot and potato.
    Went down a storm with the family.

  11. This is a truly gorgeous pie! The amount of filo is unclear though, as it says 25 sheet not grams, maybe needs a slight alterations for us greedy hopefuls 😁

    1. Hi Terry
      The recipe card actually reads 25g sheet, so the measurement is there in grams! Glad you enjoyed the pie, anyway! 😉

  12. Hi Can you please confirm the amount of tomato purée needed… is it half a teaspoon as doesn’t sound a lot. Looking forward to giving this recipe a go. Thanks Harri

    1. Hi Harri
      The recipe uses half a teaspoon of tomato puree, but you can always add more to suit your personal preference. 🙂

  13. Hi, is it 2tbsp of Worcester sauce? I know it’s stated in the receipy as tbsp but it seems a lot? Just want to check it’s no tsp before I go ahead and make it.
    Thanks J
