Cuisine: Russian
Serves: 6 servings
Ingredients
- 4 large potatoes, sliced
- 2 large onions, sliced
- 1 cup sour cream
- 1 cup cheese, grated
- Salt to taste
- Pepper to taste
- Butter for greasing
Instructions
- Preheat the oven to 375°F (190°C). Generously grease a 9x13 inch baking dish with butter to prevent sticking.
- Wash and peel the potatoes. Using a sharp knife or mandoline, slice the potatoes into thin, uniform rounds approximately 1/8 inch thick.
- Peel and slice the onions into thin, even rings. In a large skillet, heat a tablespoon of butter over medium-low heat and slowly caramelize the onions, stirring occasionally. This process should take about 15-20 minutes until the onions are golden brown and sweet.
- In a separate bowl, mix the sour cream with salt and pepper, creating a creamy seasoning mixture.
- Begin layering the casserole: Start with a thin layer of buttered potato slices covering the bottom of the baking dish. Spread a portion of the caramelized onions over the potatoes.
- Drizzle some of the seasoned sour cream over the layer and sprinkle a portion of the grated cheese. Repeat these layers until all ingredients are used, ensuring the top layer is covered with cheese.
- Cover the baking dish with aluminum foil to prevent excessive browning and place in the preheated oven.
- Bake covered for 30 minutes, then remove the foil and continue baking for an additional 15 minutes until the top is golden and crispy, and the potatoes are tender when pierced with a fork.
- Remove from the oven and let the casserole rest for 10 minutes before serving. This allows the layers to set and makes cutting easier.
- Serve hot as a hearty side dish or main course, garnishing with fresh herbs like dill or chives if desired.
Tips
- Slice Consistency is Key: Use a mandoline or sharp knife to ensure uniform potato slices. This guarantees even cooking and a beautiful layered presentation.
- Patience with Caramelization: Don't rush the onions! Slow, low-heat caramelization is crucial for developing those deep, sweet flavors that make this dish extraordinary.
- Cheese Selection Matters: Choose a good melting cheese like Gruyère, Emmental, or a sharp cheddar for maximum flavor and gooey texture.
- Prevent Dryness: The sour cream mixture helps keep the casserole moist. Don't be shy with seasoning - salt and pepper are your friends!
- Resting is Essential: Allow the casserole to rest for 10 minutes after baking. This helps the layers set and makes serving much easier.
- Make Ahead Friendly: This dish can be prepared in advance and refrigerated before baking - perfect for meal prep or entertaining!
