Ingredients
For the Potato Base:
4 large Russet potatoes or Yukon Golds, scrubbed clean and sliced into 1/2-inch thick rounds
2 tbsp Olive oil or melted butter
1/2 tsp Garlic powder
1/2 tsp Salt
1/4 tsp Black pepper
For the Cheesy Onion Topping:
1 small Yellow or sweet onion, finely diced
1 cup Shredded Swiss, Gruyère, or Cheddar cheese
1/2 cup Mayonnaise (or sour cream)
1/4 cup Grated Parmesan cheese
1/2 tsp Italian seasoning or Worcestershire sauce (optional)
Fresh chives or parsley, chopped (for garnish)
Step-by-Step Instructions
Step 1: Roast the Potato Slices
1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil lightly coated with cooking spray.
2. Toss the sliced potato rounds in olive oil, garlic powder, salt, and pepper until well coated.
3. Arrange the slices in a single layer on the prepared baking sheet.
4. Bake for 20 to 25 minutes, turning the slices over halfway through, until they are tender when pierced with a fork and light golden brown on both sides.
Step 2: Mix the Topping
1. While the potatoes are roasting, combine the finely diced onion, shredded cheese, mayonnaise, grated Parmesan, and optional Italian seasoning in a mixing bowl until thoroughly mixed.
Step 3: Top & Broil
1. Remove the potatoes from the oven and spoon a generous mound of the cheese-and-onion mixture onto the center of each cooked potato round.
2. Return the baking sheet to the oven and bake for another 8 to 10 minutes (or switch to the broiler on high for 2 to 3 minutes) until the cheese is completely melted, bubbly, and beautifully golden brown on top.
3. Let cool for 5 minutes, garnish with fresh chopped chives or parsley, and serve warm!
Chef’s Tips
Don’t Slice Too Thin: Keep slices around 1/2-inch thick so they hold up structurally under the weight of the cheese topping.
Fine-Diced Onions: Dice the onions very small so they soften completely and meld into the melted cheese while broiling.

Frequently Asked Questions (FAQ)
Can I prep these ahead of time?
Yes! You can roast the potato rounds and mix the cheese topping up to 24 hours in advance. Store both separately in the fridge. When ready to serve, place the cold potato slices on a baking sheet, add the topping, and bake at 375°F (190°C) for 12 to 15 minutes until heated through and golden!
