How to Make It

Don’t let the twice-baked cooking method intimidate you! The steps to making the perfect potatoes romanoff are really very simple. Just follow the instructions in order, and you’ll have one of the best side dishes ever!

Prepare. Start off by preheating your oven to 400°F and coating a 9×13 casserole dish with cooking spray.

Bake. Prior to baking the potatoes, place them on a baking sheet and poke hole in them with a fork. This will allow them to release steam while baking. Once poked, bake the potatoes until they’re tender. It should take about an hour.

Cool. After taking the potatoes out of the oven, allow them to cool to room temperature for about 30 minutes. Then, cover them with plastic wrap and refrigerate them until completely chilled. This should take at least 8 hours, so plan accordingly! You may want to start this recipe the night before and allow them to chill while you sleep.

Preheat. To prepare for the second bake, preheat the oven to 425°F.

Shred. Using a box grater, shred the potatoes into a large bowl.

Season. Add the shallots to the potatoes before seasoning the mix with salt, white pepper, and cayenne.

Stir. Stir everything together until it’s all thoroughly combined. Fold in 2 cups of cheddar cheese and sour cream until just combined.

Transfer. Transfer the cheesy potato mixture into the prepared baking dish, patting it gently into an even layer. Do not compact or press the potato mixture down! You want to make sure the potatoes bake up fluffy and light.

Bake again. Bake for 20 minutes, then tip with the remaining cheese. Continue baking until the cheese is melted and the top is lightly browned, an additional 5-10 minutes depending on how browned you’d like it.

Variations to Try

  • Shallots are known for their delicate flavor, but uncooked shallots still have a little bit of a bite. If you want the shallots to be entirely sweet, consider sautéing them for just a few minutes before adding them to the mixture.
  • The cheddar cheese is probably the most dominant flavor in potatoes romanoff. You can use sharp yellow cheddar like I did, or sharp white cheddar. Just make sure it’s sharp! You really want that cheddar flavor to be noticeable.
  • If you’re a garlic lover, add a teaspoon of garlic powder to the mixture. A teaspoon will add just enough garlicky flavor without it being overpowering.
