Ingredients
Scale
Potatoes
- 2 pounds Yukon Gold or russet potatoes, peeled and cut into chunks
Dairy
- 1 cup sour cream
- 4 ounces cream cheese, softened
- ½ cup unsalted butter, melted
- 1½ cups shredded cheddar cheese
Seasoning
- 1 packet (1 ounce) dry onion soup mix
- ½ cup chopped green onions
- Salt and pepper to taste
Topping (Optional)
- ½ cup crushed buttery crackers or potato chips
Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to ensure the casserole doesn’t stick during baking.
- Cook Potatoes: Place the peeled and chunked potatoes in a large pot of salted water. Boil for 15–20 minutes or until the potatoes are fork-tender, meaning they easily break apart when pierced.
- Mash Potatoes: Drain the cooked potatoes well. Return them to the pot or a large bowl and mash until smooth, removing lumps for creamy texture.
- Mix Ingredients: Stir in the sour cream, softened cream cheese, melted butter, and dry onion soup mix thoroughly until you have a well-combined, creamy mixture.
- Add Cheese and Onions: Fold in the shredded cheddar cheese and chopped green onions gently, ensuring even distribution throughout the mashed potatoes.
- Season: Add salt and freshly ground pepper to taste, adjusting seasoning according to your preference.
- Assemble in Baking Dish: Spread the potato mixture evenly into the prepared baking dish. For a crunchy topping, sprinkle crushed buttery crackers or potato chips evenly over the top if desired.
- Bake: Place the dish in the preheated oven and bake for 25–30 minutes, or until the casserole is hot and bubbly around the edges.
- Rest and Serve: Let the casserole rest for 5 minutes out of the oven before serving to allow it to set slightly for easier slicing and serving.
Notes
- This dish can be prepared a day ahead; simply refrigerate the unbaked casserole and bake it just before serving.
- For added flavor, mix in cooked bacon or caramelized onions before baking.
- This casserole is a crowd-pleasing side dish ideal for holidays, potlucks, and barbecues.
