Step-by-Step Instructions
Step 1: Prepare the Potatoes
-
Place the quartered potatoes into a large saucepan and cover with cold water.
-
Add a pinch of salt and bring to a boil over high heat.
-
Reduce the heat slightly and simmer for 15–20 minutes until the potatoes are completely fork-tender.
Step 2: Cook the Savory Filling
-
While the potatoes cook, preheat your oven to 220°C (200°C fan / Gas Mark 7).
-
Generously spray a large, non-stick frying pan with low-calorie cooking spray and place over medium heat.
-
Add the sliced leek and chopped onion, sautéing for 2–3 minutes until they begin to soften.
-
Stir in the diced chicken and bacon strips. Cook for about 5 minutes until the chicken is browned on the outside.
-
Sprinkle in the mustard powder, then pour in 300ml of the chicken stock (set the remaining 25ml aside for the mash). Bring the mixture to a gentle simmer and let it cook for 10 minutes.
-
Stir in 75g of the low-fat cream cheese and the fresh thyme leaves. Once the sauce is smooth and well combined, transfer the filling into a medium-sized ovenproof baking dish.
Step 3: Mash the Topping
-
Drain the cooked potatoes thoroughly and let them steam-dry in the colander for 2 minutes (this ensures a fluffier mash).
-
Return the potatoes to the pot and mash until completely smooth.
-
Stir in the remaining 25g of cream cheese, the reserved 25ml of chicken stock, and the chopped parsley. Season well with sea salt and black pepper to taste.
Step 4: Assemble and Bake
-
Carefully spoon the seasoned mashed potato over the chicken and bacon filling. Use the back of a fork to smooth it out and create ridges that will crisp up in the oven.
-
Evenly sprinkle the grated reduced-fat Cheddar cheese over the top.
-
Bake in the preheated oven for 25–30 minutes, or until the potato topping is golden-brown and the filling is bubbling at the edges.
-
Remove from the oven, let it cool for a few minutes, and serve warm.
