This oven baked 3-ingredient parmesan potato bake is one of those simple, cozy dishes that tastes like it took all afternoon, but really doesn’t. My grandma used to make it for Sunday dinners, and it always stole the show next to the roast and green beans. The potatoes come out perfectly fork-tender with a crispy, golden parmesan crust that makes everyone reach for seconds. With just baby potatoes, grated parmesan, and melted butter, it’s budget-friendly, kid-approved, and easy enough to throw together on a busy weeknight.
Serve this parmesan potato bake straight from the pan while it’s still hot and the cheese is crisp around the edges. It pairs beautifully with roast chicken, pork chops, or a simple skillet steak. For a lighter meal, add a big green salad with a tangy vinaigrette to cut through the richness. These potatoes also work as a fun appetizer—set the pan in the middle of the table with toothpicks and let everyone spear a few. Leftovers reheat well in the oven and are great alongside scrambled eggs for a hearty breakfast-for-dinner night.
Oven-Baked 3-Ingredient Parmesan Potato BakeServings: 4
Ingredients
2 pounds baby potatoes, washed and halved
1 cup finely grated Parmesan cheese (freshly grated if possible)
4 tablespoons unsalted butter, melted, plus extra for greasing the foil
Directions
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with aluminum foil, then lightly grease the foil with a bit of melted butter to help prevent sticking and encourage browning.
Wash and dry the baby potatoes well, then slice each one in half lengthwise so they have a flat side. Pat them dry again with a clean kitchen towel or paper towels; drier potatoes will help the cheese crisp up better.
In a medium bowl, combine the finely grated Parmesan cheese with 2 tablespoons of the melted butter. Stir until the cheese is evenly moistened and clumps together a bit. This mixture will form the golden, crispy crust on the bottom of the potatoes.
Sprinkle the buttered Parmesan mixture evenly over the greased, foil-lined baking sheet, spreading it into a thin, even layer that covers most of the surface where the potatoes will sit.
Arrange the halved potatoes cut-side down directly on top of the Parmesan layer, pressing them gently so the flat sides make good contact with the cheese. Try to fit them snugly together in a single layer without overlapping.
Drizzle the remaining 2 tablespoons of melted butter over the rounded tops of the potatoes, making sure each one gets a little. This will help them become tender and lightly browned on top.
Place the baking sheet on the center rack of the preheated oven and bake for 35–45 minutes, or until the potatoes are fork-tender and the cheese underneath is deep golden brown and crispy around the edges. Cooking time may vary slightly depending on the size of your potatoes.
Remove the pan from the oven and let the potatoes rest for 5 minutes. This short rest helps the cheesy crust firm up so it releases more easily from the foil.
Using a thin spatula, gently loosen the potatoes from the foil, scooping up that crispy Parmesan layer with them. Transfer to a serving platter, making sure each potato half gets some of the golden cheese crust. Serve warm and enjoy while the edges are still crunchy.
Variations & Tips
For picky eaters or younger kids, you can cut the potatoes into quarters instead of halves so they’re bite-sized and easier to spear with a fork. If your family prefers milder flavor, use the finely grated Parmesan from the can instead of freshly grated; it browns a little faster and has a softer, more familiar taste. To stretch the recipe for a bigger crowd, add up to 3 pounds of baby potatoes without changing the butter, but increase the Parmesan to 1 1/2 cups and use an extra-large baking sheet so everything still fits in a single layer. If you like an extra-crispy bottom, bake on the lowest oven rack for the last 5–10 minutes, keeping an eye on the cheese so it doesn’t burn. For easier cleanup, let the pan cool completely before peeling off the foil; the cheesy bits will come away more cleanly. Leftovers can be reheated on a foil-lined sheet at 375°F until warmed through and re-crisped, about 10–12 minutes.
