Ingredients
  

Main Ingredients
  • 4 medium Yukon Gold potatoes, sliced into 1/4-inch rounds Yukon Gold potatoes offer a creamy texture.
  • 1 large sweet onion, thinly sliced
  • 2 tablespoons butter, melted Melted butter to enhance flavor.
  • 1.5 cups shredded Swiss cheese Can substitute with other cheeses.

Method
 

Preparation
  1. Preheat the oven to 400°F and lightly butter or grease a rectangular baking dish or sheet pan.
  2. Arrange the potato rounds in a single overlapping layer in the prepared dish, then scatter the sliced onion evenly over the top.
  3. Drizzle with the melted butter.
Baking
  1. Bake uncovered for 30 to 35 minutes, until the potatoes are nearly tender and the onions have softened and begun to turn golden around the edges.
  2. Sprinkle the shredded Swiss cheese evenly over the potatoes and onions, then return the dish to the oven for 8 to 10 minutes, until the cheese is fully melted and bubbling.
Serving
  1. Let the dish rest for 5 minutes before serving so the cheese settles slightly and the potato rounds are easier to lift out and serve warm.

Notes

Leftovers can be stored in an airtight container in the fridge for up to three days. To reheat, simply place them back in the oven or microwave until warmed through. For extra flavor, consider adding herbs like rosemary or thyme. Ensure you slice the potatoes evenly for consistent cooking. If you prefer a crunchy top, you can broil the dish for a minute or two after baking. You can easily customize this dish by using different cheeses like cheddar or gouda or adding cooked bacon bits for an extra savory kick.
