Bacon and Portobello Mushroom Pie

Add the potato and 0.5 tsp of salt to the boiling water and simmer until tender, 15-20 mins. TOP TIP: The potato slices are cooked when you can easily slip a knife through them. Once the potato slices are cooked, ladle out some of the cooking water into a jug (see ingredients for amount) and set aside, then carefully drain the potato in a colander (don't worry if some break up!).

Meanwhile, heat a drizzle of oil in a frying pan on medium-high heat. Add the pancetta, stir and cook until browned, 4-5 mins. Add the mushrooms and season with black pepper. Cook until softened, 3-4 mins, stir every minute. Then stir in the leek, carrot and onion. Cook until soft, another 3-4 mins. Stir in the garlic, cook for 1 minute, then pour in the reserved potato cooking water.

Stir in the chicken stock powder, bring the mixture to a simmer then turn the heat to low and simmer until the water has reduced by half, 3-5 mins. Stir in the crème fraiche, bring back to the boil and then pour the mixture into a small ovenproof dish. Lay the potato slices on top. Mix the breadcrumbs with some oil (see ingredient list for amount) and season with salt and pepper. Sprinkle the crumbs on top.

Bake the pie on the top shelf of your oven until the top is golden, 8-10 mins. Meanwhile, refill your potato pan with water and bring to the boil on high heat with 0.5 tsp of salt. Once boiling, add in the beans and simmer until tender, 4-5 mins. Drain in a colander and then season with black pepper.
