Ingredients
Potato Mixture
- 3 large russet potatoes (baked and cooled overnight in the fridge)
- 3 tablespoons salted butter
- ¼ cup diced shallot
- 1 clove garlic (minced)
- 2 teaspoons salt
- ½ teaspoon ground black pepper
- 1 ½ cups sour cream
- 2 cups freshly shredded sharp white cheddar cheese
Topping
- ½ cup freshly shredded sharp white cheddar cheese
- ½ cup grated parmesan cheese
Instructions
- Preheat and Prepare Baking Dish: Preheat your oven to 375℉ (190℃) and grease a 2-quart baking dish to prevent sticking and ensure easy serving.
- Sauté Shallots and Garlic: In a small pan, melt the salted butter over medium-low heat. Add the diced shallot and sauté until softened and translucent, about 4 minutes. Stir in the minced garlic and cook for another 30 seconds before removing from heat to preserve the delicate flavors.
- Grate Potatoes: Using a box grater or food processor, grate the cooled baked russet potatoes with their skins still on. This shredding creates the signature texture of Potatoes Romanoff.
- Combine Ingredients: In a large mixing bowl, stir together the sour cream, salt, black pepper, 2 cups of shredded sharp white cheddar, and the sautéed shallots and garlic. Gently fold in the shredded potatoes, mixing until evenly combined while trying to maintain the shredded texture for a light, fluffy consistency.
- Assemble Casserole: Lightly pile the potato mixture into the prepared casserole dish, spreading it evenly. Sprinkle the remaining ½ cup sharp white cheddar cheese and ½ cup grated parmesan cheese evenly over the top to create a rich, cheesy crust.
- Bake: Place the casserole dish in the preheated oven and bake for 25 to 30 minutes, or until the top is golden brown and bubbly, indicating the cheese has melted perfectly and the potatoes are heated through.
Notes
- For best results, bake the russet potatoes the day before and refrigerate overnight to enhance texture and ease of shredding.
- You can substitute shallots with finely chopped onions if necessary, but shallots provide a subtler flavor.
- Use freshly shredded cheese rather than pre-shredded for better melting and texture.
- Make sure not to overmix the potato mixture to preserve the texture of the shredded potatoes.
- This dish pairs well with roasted meats or a fresh green salad for a balanced meal.
