A quick and delicious cheesy potato dish made in the microwave, perfect for busy weeknights or festive gatherings.
Peel and thinly slice the potatoes and onion.
Use a mandoline slicer for evenly thin slices, which ensures even cooking.
In a microwave-safe casserole dish, combine the milk, salt, and pepper.
Warm the milk slightly before mixing to help the flavors meld together.
Layer the potato and onion slices in the dish, ensuring even distribution.
Overlap the slices slightly for a more uniform texture.
Sprinkle the cheese over the top of the layered vegetables.
Reserve a small amount of cheese to add during the final cooking stage for extra gooeyness.
Cover the dish and microwave on high for 10 minutes.
Ensure the dish is covered to trap steam and cook the potatoes evenly.
Stir the mixture gently, then microwave for an additional 12 minutes or until the potatoes are tender.
Check the potatoes with a fork to ensure they are tender before serving.
Let the dish rest for 5 minutes before serving.
Resting allows the flavors to meld and the dish to set slightly for easier serving.
