If you love crispy Parmesan potatoes, cheesy potato casseroles, and traditional family recipes, this simple side dish deserves a place in your recipe collection. Every layer absorbs buttery goodness while the cheese melts between the slices, creating an irresistible combination of crunchy edges and soft, savory potatoes.
The best part? You only need three simple ingredients to prepare this budget-friendly potato side dish. It is perfect for busy weeknight dinners, Sunday family meals, holiday gatherings, and potlucks when you want something delicious without spending hours in the kitchen.
Ingredients
- 2½ pounds russet potatoes, peeled and thinly sliced
- 1½ cups grated Parmesan cheese
- 6 tablespoons unsalted butter, melted
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease an oval baking dish or a 9-by-13-inch baking dish with some of the melted butter.
- Arrange a layer of thinly sliced potatoes in the prepared dish, slightly overlapping each slice. Brush with melted butter and sprinkle evenly with Parmesan cheese.
- Continue layering the potatoes, butter, and cheese until all the ingredients are used. Finish with a generous layer of Parmesan on top for an extra-crispy, golden crust.
- Cover loosely with aluminum foil and bake for 40 minutes. Remove the foil and bake for another 20–30 minutes, or until the potatoes are fork-tender and the cheese topping is deeply golden and crisp.
- Allow the baked potato voisin to rest for about 10 minutes before serving. This helps the layers settle and makes it easier to scoop out those delicious cheesy portions.

Tips for the Best Crispy Parmesan Potatoes
Choose the right potatoes: Russet potatoes create a fluffy interior and crisp edges. Yukon Gold potatoes are another good option if you prefer a creamier texture.
Slice the potatoes evenly: Thin, uniform slices help the potatoes cook consistently. A mandoline slicer can make preparation quicker and easier.
Build flavorful layers: Distribute the melted butter and Parmesan evenly between the potato slices so every bite has a savory, cheesy flavor.
Make the top extra crispy: Remove the foil during the final 20–30 minutes of baking. For even more browned edges, use a relatively shallow baking dish.
Prepare ahead: Assemble the casserole a few hours in advance, cover, and refrigerate. Add extra baking time if placing the dish directly into the oven while cold, and make sure the center is fully tender before serving.
Add optional seasoning: Although the traditional version uses just three ingredients, a little black pepper, garlic powder, or paprika can provide extra flavor.
What to Serve With Potato Voisin
These oven-baked cheesy potatoes pair wonderfully with roasted chicken, grilled beef, baked fish, meatloaf, or a simple vegetable dinner. Add steamed green beans, roasted broccoli, or a fresh green salad to balance the richness of the buttery Parmesan layers.
For a comforting family meal, serve them with your favorite main dish and warm dinner rolls.
Frequently Asked Questions
Can I make potato voisin ahead of time?
Yes. Assemble the dish several hours ahead, cover it, and refrigerate. Allow additional baking time if it is still cold when it goes into the oven.
How do I know when the potatoes are done?
Insert a knife or fork into the center. It should slide through the potato layers easily, while the top should be golden brown and crisp.
Can I use a different cheese?
Yes. Gruyère, sharp cheddar, or a combination of Parmesan and another melting cheese can create a slightly different flavor and texture.
How should I store leftovers?
Refrigerate leftovers in an airtight container within two hours of cooking and enjoy within 3–4 days. Reheat in the oven to help restore the crispy cheese topping.
Can I freeze this potato casserole?
Freezing is possible, although the potatoes may become softer after thawing. For the best texture, prepare and bake the dish fresh whenever possible.
