Instructions

Boil the Potatoes
1

Preheat your oven to 220°C/200°C fan/gas mark 7. Bring a large saucepan of water with 1/2 tsp salt to the boil for the potatoes.

Remove the puff pastry from your fridge and allow to come up to room temperature. 

Chop the potatoes into 2cm chunks (peel first if you prefer).

When the water for the potatoes is boiling, add the potatoes to the water and cook until you can easily slip a knife through, 15-20 mins.

Meanwhile, heat a drizzle of oil in another large saucepan on medium-high heat.

Make your Pie Filling
2

When hot, add the mushrooms to the pan. Season with salt and pepper and fry, stirring occasionally, until browned, 5-6 mins.

Once browned, reduce to a low heat and gently melt the butter, then stir in the flour (see pantry for both amounts). Cook until it forms a paste, 1-2 mins - you've made a roux!

Add the tomato puree and dried thyme. Fry for another 30 secs. 

Next, gradually stir in the water for the sauce (see pantry for amount).  Add the Worcester sauce, beef stock paste and sugar for the sauce (see pantry for amount). Bring to the boil.

Assemble the Pie
3

Once boiling, lower the heat and add the slow cooked beef and its juices. Use a spoon to break up the beef as it cooks. Simmer until thickened, 4-5 mins, stirring occasionally. IMPORTANT: Ensure the beef is piping hot throughout.

Once the pie filling is cooked, season with salt and pepper, then transfer it to an appropriately sized ovenproof dish.

Cover with the pastry, pressing it over the side of the dish or just sitting it on top, then trimming off any excess.

Make a small hole in the middle to allow steam to escape. TIP: Brush the pastry with a little milk if you have some.

Time to Mash
4

Bake your pie on the top shelf of your oven until golden brown, 15-20 mins. 

Meanwhile, once the potatoes are cooked, drain in a colander and return to the pan, off the heat.

Add a knob of butter and a splash of milk (if you have any) and mash until smooth. Season with salt and pepper. Cover with a lid to keep warm.

Now for the Cabbage
5

Heat a drizzle of oil in a large frying pan on medium-high heat.

Once hot, add the bacon lardons. Stir-fry until golden, 4-5 mins. IMPORTANT: Wash your hands and equipment after handling raw meat. Cook bacon thoroughly.

Next, add the cabbage and stir-fry for 2 mins. Season with salt and pepper and a splash of water, mix well and cover with a lid (or foil). Cook until just tender, 3-4 mins.

Once cooked, remove from the heat and cover to keep warm. 

Finish and Serve
6

When everything's ready, share the steak and mushroom pie between your serving plates.

Reheat the cabbage and mash if needed and serve alongside. 

Enjoy!
