• 240 ml (1 cup)sour cream
• 227 g (8 oz), softenedcream cheese
• 2.5 ml (½ teaspoon)onion salt
• 1.25 ml (¼ teaspoon)garlic powder

• 30 g (¼ cup)dry breadcrumbs
• 57 g (½ cup), gratedsharp cheddar cheese
• 14 g (1 tablespoon), meltedunsalted butter

Instructions

1. 1

   Preheat the oven

   Heat the oven to 175°C (350°F). Lightly grease a 1.9-litre (2-quart) casserole dish with non-stick spray or butter and set it aside.

2. 2

   Boil the potatoes

   Bring a large pot of water with a pinch of salt to a rolling boil. Peel the potatoes, halve them to help them cook faster, then add them to the boiling water. Cook for about 15–20 minutes, until fork-tender.

3. 3

   Mash and mix

   Drain the potatoes thoroughly and put them in a large mixing bowl. Mash until smooth, then stir in the sour cream, cream cheese, onion salt, garlic powder and minced chives until creamy and well combined.

4. 4

   Fill the dish

   Spoon the potato mixture into the prepared casserole dish. Spread it evenly with a spatula and smooth the top.

5. 5

   Add the topping

   In a small bowl, combine the melted butter and dry breadcrumbs. Sprinkle the mixture evenly over the potatoes.

6. 6

   Bake until golden

   Bake for 40–50 minutes, until the top is golden brown and the edges are bubbling.

7. 7

   Melt the cheddar

   Sprinkle the grated sharp cheddar over the top. The heat from the potatoes will melt the cheese.

8. 8

   Garnish and serve

   Finish with extra minced chives and serve hot.

What are Party Potatoes?

Party Potatoes are an American-style casserole of mashed potatoes enriched with sour cream and cream cheese, then baked with a crisp breadcrumb topping and cheddar. They suit a shared meal because the potatoes are prepared together in one dish and served by the scoop.

This version builds flavour with onion salt, garlic powder and chives. The creamy mash contrasts with the buttery crumbs, while the cheddar adds a savoury finish.

Nutrition and macros by portion

The nutrition label shows one serving as written: 320 calories, 8g protein, 39g carbs, 16g fat.

The potatoes provide most of the carbohydrates, while sour cream, cream cheese, butter and cheddar contribute much of the fat. The cheese and cream cheese also provide some protein. Serve a portion with vegetables and a lean protein to make a more balanced plate.

Choose the right potatoes

Russets: their starchy flesh mashes into a soft, fluffy base. Peel and halve them as directed so they cook through in the stated time.

Cream cheese: soften it before mixing so it blends more readily into the warm potatoes. Sour cream adds tang and helps keep the mash creamy.

Get the mash smooth

Drain well: excess water can make the casserole loose, so let the potatoes drain thoroughly before mashing.

Mix gently: mash the potatoes until smooth, then stir in the dairy and seasonings until combined. Avoid overworking the mash, which can make it gluey.

Build the crisp topping

Buttered crumbs: mix the melted butter evenly through the dry breadcrumbs so the topping browns as it bakes. Scatter them across the surface rather than leaving them in a pile.

Cheddar finish: add the grated cheese after baking, as directed. The hot potato mixture melts it without another oven step.

Watch for doneness

Boiling: the potatoes are ready when a fork goes into them easily, usually after 15–20 minutes. Start checking towards the lower end of that range.

Baking: look for a golden top and bubbling edges after 40–50 minutes. Ovens and casserole dishes vary, so use these visual cues alongside the timing.

Plan the timing

The potatoes need time to boil and mash before the casserole goes into the oven, so allow for both stages when planning the meal. The recipe's total time is 90 minutes.

Serve the dish hot after adding the cheddar and chives. It pairs well with roasted meat or vegetables and a crisp green salad.

Recipe notes & tips

• Soften the cream cheese before you start mixing.
• Cut the potatoes into similarly sized halves so they cook at a similar rate.
• Drain the potatoes thoroughly before mashing.
• Spread the breadcrumb mixture in an even layer for consistent browning.
• Check for tender potatoes with a fork before draining.
• Garnish with the extra chives just before serving.

Variations

• Herb finish: add extra minced chives over the finished casserole.
• More cheddar: increase the grated cheddar for a cheesier topping.
• Peppery seasoning: add black pepper to the mash to taste.
• Crispier crumbs: spread the buttered breadcrumbs evenly across the whole surface.
• Smaller portions: bake the mixture in individual oven-safe dishes, checking for the same golden top and bubbling edges.

Common mistakes to avoid

• Watery mash: drain the boiled potatoes thoroughly before mashing.
• Lumpy mixture: soften the cream cheese first and mash the potatoes until smooth.
• Uneven cooking: halve the potatoes and keep the pieces similar in size.
• Patchy topping: mix the melted butter thoroughly with the breadcrumbs before sprinkling.
• Overbaking: check the casserole at 40 minutes and take it out when the top is golden and the edges bubble.

How to store

Refrigerate leftovers in a covered container and eat within 3–4 days. Reheat portions until hot throughout in the oven or microwave; the breadcrumb topping may soften after storage.
