Craving the perfect side dish that’s creamy, cheesy, and ridiculously easy to make? Potatoes Romanoff is a crowd-pleasing, make-ahead casserole that’s ideal for everything from holiday feasts to weeknight comfort food.
Pierce the potatoes all over with a fork and wrap them in aluminum foil.
Bake at 425°F for 1 hour.
Once done, refrigerate the wrapped potatoes overnight.
Tip: This recipe is also a great way to use up leftover baked potatoes!
Grate the Potatoes:
The next day, carefully grate the refrigerated baked potatoes, skin and all, using a box grater.
Assemble the Casserole:
In a large bowl or shallow dish, combine the grated potatoes, minced onion, kosher salt, freshly ground pepper, sharp cheddar cheese, and sour cream.
Mix gently using your fingers for the best results, being careful not to mash the potatoes.
Prepare to Bake:
Transfer the potato mixture into a baking dish, mounding it slightly in the center.
Drizzle the melted butter over the top and sprinkle with a bit more salt and pepper.
This can be prepared ahead of time!
Bake:
When ready to serve, preheat the oven to 375°F.
Bake uncovered for about 30 minutes, or until the casserole is hot throughout and lightly browned on top.
Notes
It’s important to refrigerate the baked potatoes overnight for the best texture. Though you can skip this step, it’s highly recommended!
You can prepare the baked potatoes ahead of time or even assemble the entire casserole (up to step 4) and bake it just before serving.
If you’re baking other dishes at the same time, you can bake this at any temperature between 350°F and 400°F. Just ensure it's hot and the top is crispy.
