Ingredients
Scale
Potatoes and Seasonings
- 2 pounds russet potatoes, peeled and cut into chunks
- 1 tablespoon kosher salt (for boiling)
- 1 packet (1 ounce) dry onion soup mix
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
Dairy
- 4 tablespoons unsalted butter
- 1 cup sour cream
- 1/2 cup whole milk
- 1/2 cup shredded cheddar cheese
Garnish
- 2 green onions, thinly sliced
Instructions
- Boil the potatoes: Place the peeled and chunked russet potatoes into a large pot and cover them with cold water. Add 1 tablespoon of kosher salt. Bring the water to a boil over medium-high heat and cook the potatoes until they are fork-tender, which should take about 15 to 20 minutes. Drain the potatoes well once cooked.
- Mash the potatoes: Return the drained potatoes to the pot. Add 4 tablespoons of unsalted butter and mash the potatoes until they are mostly smooth, leaving some texture for a hearty consistency.
- Mix in sour cream and seasonings: Stir in 1 cup of sour cream, 1/2 cup of whole milk, 1 packet of dry onion soup mix, 1/2 teaspoon garlic powder, and 1/4 teaspoon black pepper into the mashed potatoes until everything is creamy and well combined.
- Assemble and garnish: Transfer the creamy potato mixture to a serving dish. Sprinkle 1/2 cup of shredded cheddar cheese evenly on top. Garnish with the thinly sliced green onions to add a fresh, vibrant finish.
- Serve warm: Serve the party potatoes warm as a delicious side dish. For best flavor, serve immediately but you can prepare ahead and reheat before serving.
Notes
- This dish can be prepared ahead of time and reheated in the oven just before serving to save time.
- For extra flavor and texture, try folding in crispy bacon bits or caramelized onions into the mashed potatoes.
- You can adjust the milk quantity slightly to achieve your preferred creaminess level.
- Using russet potatoes provides the best texture and richness for this recipe.
