How to Make Mashed Potato Casserole

Making Mashed Potato Casserole is simple and straightforward. Follow these steps to create this delectable dish:

Ingredients:

1.75kg/3.5 lb potatoes (like Sebago, Russet, or Maris Piper)
1 tbsp cooking/kosher salt (for cooking potatoes)
2/3 cup milk (preferably full fat/whole milk but lite is okay)
2/3 cup EXTRA milk (for make-ahead option only)
75g/5 tbsp unsalted butter (cut into 1cm/1/2" cubes)
1/2 cup sour cream (or yogurt; full fat is best)
1 tsp cooking/kosher salt (or to taste)
1 1/2 cups mozzarella (freshly shredded)
1 cup Red Leicester, cheddar, or other flavored cheese
200g/6 oz bacon (streaky, chopped)
1/4 cup green onion (finely sliced)

Directions:

Cook Bacon:
- Place bacon in a cold non-stick pan over medium heat (no oil). As the pan heats up, the bacon fat will melt. Once you see some melted bacon fat, turn the heat to medium-high and cook for about 3 minutes or until golden. Drain on paper towels.
Mash:
- Peel and cut the potatoes into 3cm (1") chunks. Place them in a large pot and cover with water so it’s about 10cm (4") above the potatoes. Add 1 tablespoon salt, then bring to a boil. Lower to a simmer and cook for about 15 minutes or until soft enough to mash.
- Drain the potatoes well, return them to the pot, and let them shake in the hot pot for about one minute to encourage evaporation.
- Add milk, butter, sour cream, and 1 tsp salt, then mash until smooth.
Make-Ahead Directions:
- Once the potatoes are fully cooled, cover tightly with cling wrap and refrigerate. Take them out two hours before reheating.
Assemble:
- Preheat the oven to 200°C (400°F). Spread the mashed potatoes into a 2-litre (2 quart) baking dish and smooth the top.
- Sprinkle the potatoes with the cheeses and bacon.
- Cover loosely with foil and bake for 20 minutes (if freshly made) or 35 minutes (if made ahead).
- Remove the foil, then bake for a further 10 minutes until the cheese is bubbly and golden. Sprinkle with green onions, and serve warm!

How to Serve Mashed Potato Casserole
