My sister sent me a video of these viral parmesan crusted potatoes and insisted I drop everything and make them. I rolled my eyes a little… until I pulled the pan from the oven and saw those insanely golden, lacy cheese edges. You only need four basic ingredients and a sheet pan to get potatoes that are crispy and browned on the bottom, tender and buttery in the middle, and showered in salty parmesan. This has become my go-to side dish on busy weeknights because it feels special without any extra work.
These 4-ingredient parmesan crusted potatoes are perfect with roasted chicken, steak, pork chops, or salmon, but they also hold their own next to a simple green salad if you’re keeping things light. I like to serve them right in the baking dish so everyone can scoop up those crispy cheese shards from the bottom. Add a quick veggie like steamed green beans or roasted broccoli and you’ve got a full dinner with almost no extra effort. They’re also great as a game-day snack with a little sour cream or Greek yogurt for dipping.
4-Ingredient Parmesan Crusted PotatoesServings: 4
Ingredients
1 1/2 pounds baby potatoes, halved
1/3 cup unsalted butter, melted
3/4 cup finely grated parmesan cheese (from a wedge, not pre-shredded)
1 teaspoon kosher salt
Directions
Preheat your oven to 400°F (200°C). Grab a medium white ceramic baking dish or similar oven-safe dish where the halved potatoes can fit in a single, snug layer, cut-side down.
Pour the melted butter into the bottom of the baking dish and tilt the dish so the butter evenly coats the entire base.
Sprinkle the grated parmesan cheese evenly over the melted butter, making sure to cover the whole bottom of the dish in a thin, even layer. Try not to leave any big gaps so every potato gets a cheesy crust.
Sprinkle the kosher salt evenly over the parmesan layer. The cheese is salty too, so this small amount of salt is enough to season the potatoes without overdoing it.
Place the halved baby potatoes cut-side down directly onto the parmesan layer. Press each potato gently so it makes good contact with the cheese and butter—this is what gives you those super crispy, golden edges.
Bake, uncovered, for 30 to 40 minutes, or until the potatoes are fork-tender and the parmesan around the edges is deep golden brown and crisp. The exact time will depend on the size of your potatoes and your oven.
Remove the dish from the oven and let the potatoes rest for 5 minutes. This short rest helps the cheesy crust firm up so it releases from the bottom of the dish more easily.
Use a thin spatula to loosen and lift the potatoes from the baking dish, scraping up that crispy parmesan layer underneath each one. Serve immediately, scooping everything into a serving dish or bringing the baking dish straight to the table.
Variations & Tips
To keep this true to the four-ingredient idea, I leave out extra seasonings most nights—but once you’ve made it as written, you can play a bit. Add freshly cracked black pepper or a pinch of garlic powder over the parmesan before baking for more flavor, or toss the finished potatoes with a handful of chopped fresh parsley for color. If you only have larger Yukon gold potatoes, just cut them into thick rounds or wedges and keep an eye on the bake time. For easier cleanup, you can lightly grease your ceramic dish before adding the butter if your dish tends to stick, but the butter and cheese usually create enough of a nonstick layer. Food safety tips: Always refrigerate leftover potatoes within 2 hours of baking and store them in a covered container for up to 3–4 days. Reheat in a hot oven or air fryer so the parmesan crust crisps back up. Make sure the potatoes are cooked until tender all the way through (a fork should slide in easily) to ensure even cooking and the best texture.
