Crispy Parmesan Potatoes Recipe

This is my go-to crunchy, cheesy side that somehow feels fancy and lazy at the same time: thinly smashed potatoes roasted until the edges are gunmetal-crisp, tossed with golden Parmesan and a little herb kick. It’s the kind of thing that gets devoured before the main course even hits the table, and somehow the kids think it’s a snack so they eat twice as many. Try it because it’s stupidly easy, looks impressive, and pairs with almost anything—weeknight dinners, game-day spreads, or when you want to pretend you’re hosting a dinner party.

My husband calls these “the crunchy babies” and will start asking for them as soon as I say dinner plans out loud. One lazy Sunday I made a double batch because I forgot to buy bread; by the time I rinsed the dishes there were only crumbs and his guilty grin. They’re one of those recipes that made the rotation fast—simple ingredients, forgiving technique, and they travel well to potlucks. Also, confession: I once swapped Parmesan for a half-pack of shredded cheddar and—surprise—it was weirdly delicious, although not as nutty.

This is one of those recipes where the messy bits are charming. You’ll probably fling parmesan dust everywhere, and that’s okay—wipe it on your jeans, it’ll add flavor. I tested this both by smashing potatoes with a jar (predictable) and with the flat side of a spatula (faster), and both worked; one gave prettier edges but the other is for when the baby needs a snack RIGHT NOW. If you forget to preheat the pan, you’ll lose crispiness—learned that after several sad, floppy batches. Also: don’t be precious about perfect shapes. Irregular potatoes = more crunchy corners = win.

Shopping Tips

– Vegetables: Choose small to medium waxy or all-purpose potatoes (Yukons or red potatoes hold their shape best); avoid giant baking potatoes unless you want big wedges.
– Cheese: Freshly grated Parmigiano-Reggiano gives the best nutty flavor and crisp; pre-shredded works in a pinch but won’t brown quite the same.
– Fats & Oils: Use a neutral oil with a high smoke point (avocado or light olive oil) for the roast; a drizzle of extra-virgin at the end adds flavor.
– Spices: Keep kosher salt, cracked black pepper, and garlic powder on hand—simple and reliable seasoning beats complicated blends here.
– Fresh Herbs: Parsley or rosemary are my top picks; parsley brightens, rosemary adds piney depth—buy a small bunch and it’ll last through several batches.

Prep Ahead Ideas

– Par-boil or steam the potatoes the day before, cool, and refrigerate in an airtight container; smash and roast the next day for faster finishing.
– Grate the Parmesan ahead and keep it wrapped in the fridge or freezer to save time (and avoid the weird clumpy store stuff).
– Mix the dry seasoning in a little jar so you can shake it on quickly; store smashed raw potatoes on a tray covered with plastic in the fridge for a few hours if needed.

✔Time-Saving Tricks

– Par-cook potatoes in the microwave or steam to shave roasting time—smash, sprinkle cheese, then finish under a hot broiler for extra speed.
– Roast on a baking sheet with convection/fan on if your oven has it; the air circulation helps crisp all the nooks.
– Use pre-grated or Pecorino if you’re in a real rush—texture changes, flavor is still good.
– Don’t rush the resting: let them sit a minute off the heat so the cheese sets into a crisp shell.

✔Common Mistakes

– Not drying potatoes after boiling: wet potatoes = steam, not crisp. I’ve made gluey batches—pat dry with paper towels.
– Crowding the pan: if they’re touching too much, they steam instead of brown. Use two sheets if needed.
– Adding salt too late: season before roasting so the salt can do its thing; but taste after and adjust.
– Burning the cheese under the broiler: watch closely—cheese goes from golden to bitter fast. If that happens, scrape off the black bits and toss the rest.

What to Serve It With

– A big green salad or simple arugula with lemon to cut the richness.
– Roasted chicken or sheet-pan salmon for an easy, balanced meal.
– Steamed green beans or garlicky sautéed spinach for a veggie boost.
– Serve with a quick lemon-garlic aioli or plain Greek yogurt for dipping.

✔Tips & Mistakes

– Smash just enough to flatten—too thin and they’ll burn, too thick and they won’t crisp.
– Use a heavy baking sheet for more even browning; thin pans can give hot spots.
– Salt before roasting, but finish with a tiny flake of flaky sea salt if you want a finishing crunch.
– If they go limp after cooling, pop them briefly under the broiler to re-crisp.

✔Storage Tips

Store leftovers in an airtight container in the fridge for 3–4 days. Reheat on a sheet pan in a hot oven or toaster oven to re-crisp—microwaving makes them sad and soft. Cold? Totally edible and fine for breakfast—slice, toss an egg on top, and call it brunch. No judgment here.

✔Variations and Substitutions

– Swap Parmesan for Pecorino Romano for saltier, tangier goodness; cheddar will work but melts differently.
– Try a sprinkle of smoked paprika or chili flakes for a smoky or spicy twist.
– Use sweet potatoes for a sweeter, softer version—expect less crunchy-edge behavior but still delicious.
– Gluten-free? Skip any panko crusting and use just cheese and seasonings—still crispy enough if roasted well.

Instructions

Preparation Steps

• Preheat oven to 425°F. Line a rimmed sheet pan with parchment and brush it lightly with olive oil.
• Cut potatoes into 1-inch pieces. Rinse briefly, then pat very dry so they crisp well.
• Toss potatoes with remaining olive oil, melted butter, cornstarch, garlic powder, onion powder, smoked paprika, salt, pepper, and red pepper flakes.
• Sprinkle 1/2 cup of the Parmesan evenly over the prepared pan to form a cheesy base.
• Arrange potatoes cut-side down on the cheese. Roast 30–35 minutes until deep golden and tender.
• Loosen potatoes with a thin spatula, flip, and roast 5–10 minutes more to crisp the tops.
• Transfer to a platter. Shower with remaining Parmesan and parsley. Rest 2 minutes, then serve hot.

Notes

Try lemon zest and chopped rosemary with the seasonings, or swap smoked paprika for Cajun spice. Serve with garlic aioli, ranch, or warm marinara. Store leftovers in an airtight container up to 3 days; re-crisp in a 425°F oven for 8–10 minutes or air fryer at 375°F for 5 minutes.
