Our Monday pie was originally shared on Recipe This in 2018. This is the updated version with more photos and including our delicious Tuesday Carbonara.
Can we talk leftovers? Yes, I know I have featured many of them on here before, but I am a leftover junkie and get a HUGE buzz out of exciting recipes made from fridge leftovers.
We will be sat at the dinner table and our grown up son will be joining us. He is 19 years old and pretends he has an appetite like Joey out of Friends when he doesn’t.
Then I will watch to see how much more roast dinner he will go back for, because I am secretly thinking in my head what I can make with the leftovers.
My favourite use of leftovers is roast dinners. That is because you have lots of different flavours going on and you can mix and match to make great meals.
It might be for the next day or for the freezer for another time.
If I were to choose my top leftover meal it would be our air fryer turkey burgers, that are made from leftover Christmas dinner grub.
Or the same leftovers transformed into Boxing Day Soup.
But the greatest thing about the Monday pie, is that it can be used with any leftover roast dinner and doesn’t just have to be reserved for one type of meat.
What Is Monday Pie?
Monday Pie is a famous leftover roast beef pie in the United Kingdom that many families enjoy so that they can save money.
The idea behind Monday Pie is that you use up everything that you have left over from your Sunday roast dinner the day before, fill it out with fillers such as extra potato or beans and then serve it up as a delicious leftover meal.
For many families though (myself included) its not necessarily about the saving money element, even though that is of course nice!
It’s about the fact that you can prepare a delicious evening meal the night before, in the middle of doing your washing up.
Then the next day you simply grab your Monday Pie filling from one bowl in the fridge and load into the slow cooker.
Then you grab your leftover mashed potatoes from another and load it all up.
Come back at dinner time and you have Monday pie!
Of course, Monday Pie is whatever you want it to be. You could use up leftover roast turkey, roast pork, roast beef, roast duck, roast chicken or even leftover mince.
Our Monday Pie Ingredients
I am taking you behind the scenes of one of the Monday meat pies we made in the Milner house. We enjoyed a roast pork dinner and here is what we enjoyed on the Sunday dinner table:
- Pork Roast
- Yorkshire Puddings
- Mashed Potato
- Vegetable Bake
- Pork Gravy
We had quite a bit of potatoes left, a decent amount of pork, but the rest of it was small portions. But when combined made a big Monday Pie.
Just think about the roast dinner you have it home and how you could bulk it up and what you could include in your own Monday Pie.
My mum always said to me that “my world is my oyster” well your Monday Pie is your oyster.
Think outside the box of what you have leftover and what extra cheap sides you can add to your roast dinner to make your Monday pie super successful.
How To Make Monday Pie?
The quick version of making Monday pie goes as follows:
- Mix ingredients with your hands and load into your slow cooker. Leave in the fridge overnight.
- Load up your slow cooker Monday pie filling with mash.
- Cook + eat.
There is a little more to it than that, but those are the simple basics!
Monday Pie On Slimming World
All you are doing is using up leftovers from the day before. Maybe bulking it up a little if you don’t have enough to stretch.
Therefore, if you are on Slimming World, then use your Slimming World friendly food from the day before.
I love using up every bit of food that is leftover, so no wonder we ended up with a Tuesday carbonara too.
I love creamy sauces and a carbonara from spare meat and vegetables is do delicious.
What I did to make a Tuesday carbonara was:
- One leftover ladle of Monday pie including some mash was blended to make a creamy carbonara sauce.
- I added a little white wine, some parsley and some salt and pepper to make a thick carbonara sauce.
- I then added some more of the leftover meat I had not used.
- Added in bacon, spinach, fresh tagliatelle, grated cheese, and frozen sweetcorn.
Just like that I had Tuesday carbonara and it was like a new meal in itself and so delicious.
The sauce was gluten free and the potatoes were the thickener to make it wonderfully creamy.
Plus, this is exactly what I do with leftover turkey and turn it into a mix between a carbonara or a stroganoff.
