Serves: 6
Ingredients
For the Base
-
Potatoes: 1 kg (2.2 lbs) floury potatoes like Maris Piper or Russets, peeled and diced into 2cm (¾ inch) cubes
-
Chicken: 500g (1.1 lbs) boneless, skinless chicken thighs or breasts, cut into bite-sized chunks

Olive oil: 2 tbsp

Salt: 1½ tsp

Black pepper: 1 tsp

The Creamy Binder

-
Garlic: 2 cloves, minced
The Cheesy, Crispy Top
-
Mature cheddar: 200g (2 cups), freshly grated
-
Mozzarella: 100g (1 cup), grated or torn — for that stretchy pull

Method
1. Preheat and Prep
Preheat the oven to 200°C / 400°F / Gas Mark 6. Grease a large baking dish (about 23x33cm / 9×13 inches).
2. Season the Chicken and Potatoes
In a very large bowl, toss the diced potatoes and chicken chunks with the olive oil, salt, pepper, garlic powder, smoked paprika, and onion powder until everything is evenly coated.
3. Make the Creamy Binder
In a separate bowl or jug, whisk together the sour cream, double cream, softened cream cheese, and minced garlic until smooth. Stir in half the crumbled bacon and half the sliced spring onions. Season lightly with a pinch of salt and pepper.
4. Assemble the Casserole
Spread the seasoned potatoes and chicken in an even layer in the prepared baking dish. Pour the creamy mixture over the top, using a spatula or the back of a spoon to spread it evenly and get it down into the gaps.
5. First Bake (Covered)
Cover tightly with foil and bake for 35 minutes. This steams the potatoes and chicken to tender perfection without drying them out.
6. Add the Cheese & Crisp the Top
Remove the foil. Sprinkle the grated cheddar and mozzarella evenly over the top, along with the remaining crumbled bacon. Return to the oven, uncovered, for a further 15-20 minutes until the cheese is deeply golden, bubbling, and crisping at the edges, and the potatoes are completely tender when pierced with a knife.
7. The Crucial Crispy Finish
For that extra-crispy, almost fried-cheese texture, switch the grill on for the final 2-3 minutes. Watch it closely — the cheese should blister and turn golden brown in spots. Remove from the oven and let it rest for 5-10 minutes.
8. Garnish and Serve
Scatter with the remaining fresh spring onions. Spoon generously onto plates, making sure everyone gets those crispy cheesy corner bits.
Tips for Perfection
-
Dice potatoes small and evenly. 2cm cubes ensure they cook through in the same time as the chicken. Larger chunks will still be hard.
-
Don’t skip the foil stage. Without it, the creamy mixture can separate and the potatoes won’t steam properly.
-
Freshly grate your own cheese. Pre-grated cheese contains anti-caking agents that prevent it from melting into that silky, stretchy texture.
-
Rotisserie chicken shortcut: Use 3 cups of shredded cooked chicken instead of raw. Reduce the first bake time to 20 minutes (the potatoes need that covered time), then proceed.
Variations
-
Buffalo Chicken Version: Add 3 tbsp buffalo hot sauce to the creamy mixture and swap cheddar for a blue cheese crumble on top.
-
Southwest Style: Add a can of drained black beans and sweetcorn, use pepper jack cheese, and top with avocado and coriander.
-
Broccoli Chicken: Tuck small florets of blanched broccoli in among the potatoes before baking.
Serving Ideas
-
A crisp green side salad with a sharp lemon vinaigrette to cut through the richness
-
Garlic green beans or steamed tenderstem broccoli
-
A dollop of extra sour cream and hot sauce at the table
