Ingredients
Scale
Potatoes
- 3 large russet potatoes, baked and cooled
Mix-ins
- 1 cup sour cream
- 1 ½ cups shredded sharp cheddar cheese, divided
- ½ small onion, finely minced
- Salt and pepper to taste
Topping
- 2 tablespoons melted butter
- Optional: chopped chives or parsley for garnish
Instructions
- Bake & cool: Preheat your oven to 400°F (200°C). Bake the whole russet potatoes for about 1 hour until tender when pierced with a fork. Allow them to cool completely, then refrigerate for a few hours or overnight to make shredding easier.
- Grate & mix: Peel the cooled potatoes and grate them using a coarse grater. In a large bowl, combine the grated potatoes with sour cream, half of the shredded cheddar cheese, the finely minced onion, and season with salt and pepper to taste. Mix gently to keep the potatoes fluffy and avoid overmixing.
- Assemble: Lightly grease a baking dish. Spoon the potato mixture evenly into the dish. Sprinkle the remaining shredded cheddar cheese evenly over the top, then drizzle with the melted butter.
- Bake: Reduce oven temperature to 350°F (175°C). Bake the assembled casserole for 30 to 35 minutes or until the cheese is golden and bubbly and the dish is heated through.
- Serve: Remove from oven and let rest for 10 minutes. Garnish with chopped chives or parsley if desired before serving.
Notes
- Use baked potatoes instead of boiled for the best texture and flavor.
- Do not overmix the potato mixture to preserve a light and fluffy consistency.
- This dish can be prepared up to one day ahead—assemble and refrigerate, then bake just before serving.
