Mashed Potato, Cheese, and Ham Pie
For the Mashed Potato Layer
800 g russet potatoes, peeled and chopped
60 g unsalted butter
120 ml whole milk (or cream for extra richness)
¾ tsp salt
½ tsp black pepper
For the Ham & Cheese Layer
200 g cooked ham, diced
150 g sharp cheddar cheese , shredded
1 small onion, finely chopped
1 tbsp olive oil
1 tsp Dijon mustard (optional but recommended)
For the Top
1 egg, beaten (for egg wash)
Remaining salt and pepper
Optional: Extra cheddar cheese or crispy fried onions for topping

 

Boil the Potatoes
Place the chopped potatoes in a large pot and cover with cold, salted water.
Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15–20 minutes , or until the potatoes are fork-tender.
Drain well and return them to the warm pot.
Mash the Potatoes
Add butter, milk, 3/4 tsp salt and 1/2 tsp black pepper to the hot potatoes.
Mash until smooth and creamy using a potato masher or hand mixer.
Set aside while preparing the filling.
Sauté the Onions
In a skillet over medium heat, warm the olive oil .
Add the chopped onion and sauté for 5–7 minutes , until softened and lightly golden.
Remove from heat.
Layer the Pie
Preheat your oven to 190°C.
Use a 9-inch pie dish or oven-safe skillet and begin layering:
Spread half of the mashed potatoes evenly across the bottom.
Sprinkle half of the cheddar cheese over the potatoes.
Add the sauteed onions and stir in the Dijon mustard if using.
Spoon the diced ham over the top.
Repeat layers: potatoes, cheese, ham.
Finish with a final layer of mashed potatoes on top.
Brush the top with the beaten egg to create a golden crust when baked.
If desired, sprinkle with extra cheese or top with crispy fried onions for crunch.
Bake Until Golden
Transfer the pie dish to the preheated oven and bake for 25–30 minutes , or until the top is golden and slightly crisp around the edges.
Let cool for 5–10 minutes before slicing and serving.
Tips for Success
Warm Milk & Butter: Helps create smoother, silkier mashed potatoes.
Ham Options: Use leftover baked ham, deli ham, or smoked ham cubes.
Cheese Swap: Try Gouda, Monterey Jack, or Parmesan for different flavour profiles.
Make Ahead: Assemble the pie ahead and refrigerate overnight. Add 10 minutes to baking time if starting cold.
Double It: Make two pies—one to enjoy now, one to freeze for later!
