Potatoes Romanoff – the ultimate cheesy potato casserole made with grated baked potatoes, sour cream, and sharp cheddar. Pure comfort.
If you’re looking for a side dish that quietly upstages the main course, this is it. Potatoes Romanoff takes baked potatoes, loads them up with sharp cheddar and sour cream, and turns them into something rich, creamy, and ridiculously satisfying.
I’ve made this for holidays, Sunday roasts, and even midweek dinners when I’ve got leftover baked potatoes hanging around. It’s easy, no fuss, and exactly the kind of comfort food I crave when I want something familiar, but better. Remo went back for thirds. Jack and Solo stood guard. This is the kind of dish you pull out when you want cozy, cheesy, and completely crowd pleasing.
Why You’ll Love This Potatoes Romanoff
- Leftover baked potatoes = gold. This is the recipe for using up extras in the best way possible.
- Creamy, cheesy, cozy. Sharp cheddar and sour cream make this rich and tangy without being heavy.
- A side dish that steals the spotlight. It’s not just a side, it’s the side.
- Perfect for holidays or weeknights. Fancy enough for the roast, easy enough for meatloaf.
- Make-ahead friendly. Prep it the day before and bake when ready, stress-free and still impressive.
- Use russets, not Yukon Gold. I know Yukon Golds are pretty, but they’re too waxy here. You want russets for that fluffy, fall-apart texture once grated.
- Cool those potatoes. Don’t rush it. Let them cool completely before grating or you’ll end up with mashed potatoes, not light, airy shreds. (Been there.)
- Grate with the skins on. Sounds weird, but trust me, they add a bit of texture and flavor and basically vanish into the mix once baked.
- Cheddar is classic, but not mandatory. Sharp cheddar gives that tangy, melty richness, but you can swap in Gruyère, Monterey Jack, or even a mix. Just don’t use pre-shredded if you can avoid it, it melts weird.
- Sour cream makes it creamy, not runny. No milk, no butter, no extra fuss. The sour cream does it all, binds everything and gives that signature tang.
- Want to make it ahead? Mix it all together, cover, and refrigerate overnight. Then just bake it when you’re ready. It’s a side dish that waits for you.
Preheat the oven to 400°F (200°C). Prick your russets with a fork a few times and place them straight on the oven rack (no pan!). Bake for about 1 hour, or until tender with crispy skins. Let them cool completely, this part matters.
Once cool, grate the potatoes (skins and all) using the large holes on a box grater. If they’re too soft to grate cleanly, you can pulse them in a food processor until chunky, not mashed.
In a large bowl, gently combine the grated potatoes with diced shallots, sour cream, most of the shredded cheddar (save some for the top), and salt and pepper. Don’t overmix, just enough to pull it together.
Butter a casserole dish, spoon in the mixture, and spread it evenly. Sprinkle the remaining cheddar over the top. Lower the oven temp to 350°F (175°C) and bake for 30–35 minutes, or until bubbly and golden on top.
Let it rest for 5 minutes, then garnish with chopped chives. Serve warm and watch it disappear.

Frequently Asked Questions
Can I use Yukon Gold potatoes instead of russet?
Technically, yes, but they’re waxier, so the texture will be creamier and less fluffy. If you want that classic baked potato feel, stick with russets.
Can I make this ahead of time?
Absolutely. Prep the entire dish, cover it tightly, and refrigerate overnight. Bake it fresh the next day, it actually tastes better that way.
Can I freeze it?
Yes, but heads up: the texture might change a bit. It’s best fresh, but leftovers freeze fine for up to 3 months. Just thaw in the fridge overnight before reheating.
Can I add anything to it?
Totally! Try mixing in cooked bacon, caramelized onions, chopped jalapeños, or even a little smoked paprika for extra oomph.
Storage + Reheating
- Fridge: Store leftovers in an airtight container for up to 4 days. The flavor only gets better.
- Freezer: Freeze tightly wrapped or in a freezer safe container for up to 3 months. Just know the texture may be a little softer after thawing.
- To reheat: Bake covered at 350°F (175°C) for 15–20 minutes, or until warmed through. For that crispy top, uncover for the last few minutes.
- In a hurry? Microwave it in short bursts, just know the texture won’t be quite as magical.

Instructions
- Preheat your oven to 400°℉ (200℃). Prick the potatoes with a fork several times and bake directly on the oven rack for about an hour, or until they're cooked through and the skins are crispy. Allow them to cool completely.
- Once the potatoes have cooled, grate them (with the skin on) into a large mixing bowl.
- Add the diced shallot, shredded cheddar cheese (reserve a small amount for the topping), sour cream, and a good pinch of salt and pepper. Gently mix everything together until well combined.
- Lower your oven temperature to 350℉ (175℃). Butter a baking dish and add the potato mixture. Spread it out evenly, then top with the reserved cheese. Bake for about 30-35 minutes, or until the top is golden and bubbly.
- Remove the dish from the oven and let it cool slightly. Sprinkle the chopped chives over the top before serving.
Equipment
Notes
- Use russet potatoes for the fluffiest texture, no waxy spuds here.
- Let the potatoes cool completely before grating or you’ll end up with mash.
- Grate with the skins on: they add great texture and you won’t even notice them once it’s baked.
- Swap the cheese if you want: Gruyère, fontina, or a sharp cheddar blend all work beautifully.
- Make it your own with bacon, chives, or a little spice. It’s a side dish with main character energy.
