Boil and prep potatoes
- Boil whole unpeeled potatoes in water for 20-25 minutes until just tender, then cool completely. Once cool, peel and shred the potatoes.
Mix and assemble
- Preheat the oven to 350F, and butter a 9x13-inch baking dish. Mix sour cream, 1 cup cheddar, Parmesan, green onions, butter, salt, pepper, and garlic powder until smooth.
- Gently fold the shredded potatoes into the sour cream mixture. Spread the mixture into the prepared dish and top with the remaining cheddar.
Bake and garnish
- Bake at 350F for 40-45 minutes until hot and golden on top. Add fresh chives as a garnish, then serve.
Notes
For the creamiest Romanoff-style texture, cool the boiled potatoes completely before shredding so the mixture stays thick instead of watery. Store leftovers covered in the refrigerator for up to 4 days; reheat in a 325F oven until warmed through. Freezing is not recommended because the sour-cream base can break after thawing. For a lighter option, use reduced-fat sour cream and part-skim cheddar to cut calories while keeping the same bake method.
