  • 2 large onions
  • 2 cups milk
  • salt
  • pepper

Instructions

  1. Into a baking dish, put a layer of thin sliced potatoes, salt, pepper, and dots of butter.
  2. Add a layer of thin sliced onions. Cover these with dots of butter, salt, and pepper.
  3. Repeat until all potatoes and onions are used.

Tips & Substitutions

For best results, use starchy potatoes like Russets, as they create a creamy texture. If you prefer a lighter dish, substitute half of the milk with vegetable broth. Adding a sprinkle of cheese, like cheddar or Gruyere, between layers can enhance the flavor. Ensure potatoes are sliced uniformly for even cooking. You can also mix in some herbs, such as thyme or rosemary, for added depth.

Serving Suggestions

Serve scalloped potatoes as a hearty side dish alongside roasted meats or a fresh salad. They pair beautifully with Cucumbers In Sour Cream With Fresh Dill for a refreshing contrast. For a complete meal, consider adding some steamed vegetables or a light protein. This dish is also excellent as a comforting main course for a vegetarian dinner.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) until warmed through, about 20-25 minutes, or microwave in short intervals, stirring occasionally. If the dish seems dry, add a splash of milk before reheating to maintain creaminess.

Frequently Asked Questions

Can I use different types of potatoes for this recipe?

Yes, you can use a variety of potatoes, but starchy potatoes like Russets or Yukon Golds work best for a creamy texture. Waxy potatoes, like red or new potatoes, may not yield the same creaminess but can still be used for a different texture.

How do I know when the potatoes are done cooking?

The potatoes are done when they are tender and can be easily pierced with a fork, and the top is golden brown. This typically takes about 45 minutes to an hour in a moderate oven at 350°F (175°C), but cooking times may vary based on your oven and the thickness of your potato slices.

Can I make this dish ahead of time?

Absolutely! You can assemble the dish up to a day in advance, cover it tightly, and refrigerate. When ready to cook, simply add a few extra minutes to the baking time, as it will be colder from the fridge. This allows flavors to meld beautifully before serving.
