It sounds like you’re talking about a simple 4-ingredient layered side dish that bakes into crispy, golden edges. One very popular version is a Layered Potato & Onion Bake—super easy and delicious.
4-Ingredient Layered Potato Side Dish
Ingredients
- 4–5 large potatoes, thinly sliced
- 1 large onion, thinly sliced
- 1 cup shredded cheese (cheddar works great)
- 3–4 tablespoons butter, melted
Instructions
- Preheat the oven to 375°F (190°C).
- Grease a baking dish lightly with butter or oil.
- Layer the ingredients:
- Start with a layer of sliced potatoes.
- Add a few onion slices.
- Sprinkle a little cheese.
- Repeat the layers until everything is used.
- Pour melted butter evenly over the top.
- Cover with foil and bake for 35 minutes.
- Remove the foil and bake another 20–25 minutes until the top is golden and the edges turn crispy and caramelized.
💡 Tip:
For extra crispy edges, bake it in a metal or cast-iron pan and let the potatoes touch the sides of the dish.
It comes out soft and creamy inside with crunchy edges, which is why people love it so much.
