Creamy broccoli potato filo pie

Ingredients

For the filling: 

• 350g broccoli
• 100g garden peas
• 2 leeks
• 350g potatoes

For the pastry top:

• 4 sheets filo pastry
• 4 tbsp oil

For the white sauce:

• 1 bunch bay leaves
• 1 pinch black pepper
• 1 tbsp dijon mustard
• 1 tsp garlic powder
• 1 lemon, the juce and zest of half
• 700ml oat milk
• 1 tsp onion powder
• 4 tbsp plain flour 
• Pinch of salt & pepper
• 4 tbsp oil

Directions

1. Preheat oven to 180 degrees.
2. Remove the filo pastry from the freezer the night before you make this dish to defrost in the fridge.
3. Cut leeks in half lengthwise and then into slices, rinse well in a colander in the sink to remove any sediment, drain well, toss in 1 tsp of oil and a generous pinch of salt and roast in the oven for 15  minutes until soft and cooked through.
4. Cut the potatoes into bite-size pieces and boil until they are just soft and cooked
5. Cut the broccoli into bite sized florets and boil along with the potatoes until just cooked through, this should take about 5 minutes, use a slotted spoon to remove from the pot of boiling water. Take care not to overcook and run under cold water to stop them cooking, set aside
6. For the white sauce - In a saucepan, heat the milk along with the herbs, salt and seasoning and bring to the boil. Reduce to a simmer and leave to simmer for a few mins for the flavours to infuse. The longer you leave to simmer the stronger the flavours will be. In another pot, add the olive oil and once hot, sieve in the flour and cook for 1-2 mins stirring continuously with a whisk until golden. Sieve the infused milk and slowly add to the roux (the flour and oil mixture) stirring continuously. Bring to the boil and leave reduce to a simmer being careful that nothing sticks to the bottom. Simmer until the sauce has reached the desired degree of thickness and remove from the heat
7. When the sauce is cooked, check for seasoning and mix in the potatoes, broccoli and leeks carefully, add the mixture to the ovenproof dish (roughly 30 x 22 x 5cm)
8. Time to add the filo pastry top to the pie, taking one sheet of pastry at a time, place a sheet of filo pastry on top of the pie dish and using a pastry brush, brush it generously with olive oil, repeat this process with all 4 sheets of pastry and tuck any excess pastry at the edges into the pie dish so it is sealed nicely.
9. Bake in the oven for 20 minutes or until the pastry is golden brown and the filling is cooked through and bubbling.
