Crispy Garlic Parmesan Potatoes (Oven Roasted, Golden and Simple)

Some side dishes come back to the kitchen half eaten. These garlic Parmesan potatoes never do. They roast up golden and crunchy outside, soft and fluffy in the middle, with a salty, garlicky layer of Parmesan that toasts right onto every piece. When the whole family is home, the grandkids hover by the stove and sneak them off the sheet pan before I can even find a serving bowl.

They could not be much simpler, either. Chop the potatoes, coat them in a slick of olive oil, then add Parmesan, garlic and a few spices, then spread them out on a pan. The oven handles almost everything while you finish the rest of the meal. They go with nearly any main dish, from a Tuesday chicken to a Christmas roast, and the leftovers warm up better than you might expect.

I have roasted potatoes for my family for more than thirty years, and along the way I picked up a handful of small tricks that separate decent potatoes from truly crispy ones. All of them are right here, so your very first pan comes out just the way you hoped.

Why this recipe works

• Yukon Golds. Their thin skins turn crisp in the oven, and their creamy, buttery insides never go dry or mealy.
• Same size pieces. Cutting everything into 1 inch chunks means all the potatoes finish cooking together.
• A preheated pan in a hot oven. Potatoes that land on hot metal begin browning immediately rather than steaming.
• Room to breathe. One layer with a little space around each piece lets steam escape, so the edges turn golden and crunchy.
• Cheese twice. Half the Parmesan goes on early to build a crust, and the rest goes on at the end for fresh, nutty flavor.

Ingredients you’ll need

Everything here is a pantry staple. You will find full amounts in the recipe card below.

• Yukon Gold or baby potatoes
• Olive oil
• Fresh garlic
• Finely grated Parmesan
• Garlic powder and onion powder
• Italian seasoning or dried oregano
• Paprika
• Salt and pepper
• Fresh parsley to finish
• A little butter, if you want extra richness

Ingredient notes and smart substitutions

Potatoes

For roasting, Yukon Golds are hard to beat. They keep their shape, brown nicely and taste naturally buttery. Baby reds are excellent too, and small ones only need to be cut in half or in quarters. Russets can be used, though their extra starch makes them fragile, so be gentle when you turn them. Do not bother peeling. The skins bring color, flavor and extra crunch.

Parmesan

Choose finely grated Parmesan over shredded. The powdery texture sticks to the potatoes and bakes into a thin, crackly crust. Freshly grated from a wedge tastes best, though the finely grated cheese sold in a tub is a perfectly good shortcut here. Pecorino Romano adds a sharper, tangier twist.

Garlic

I use garlic in two forms. Garlic powder coats each piece evenly and holds up through the whole roast without burning. Fresh minced garlic tastes sweeter and deeper, but it can blacken if it sits on the hot pan for 40 minutes, so I wait to add it until the halfway point. Garlic lovers can easily add another clove or two.

Olive oil and butter

Olive oil is the key to crispness, so be generous with it. A spoonful of melted butter added in the final toss makes them taste like something from a steakhouse. If you prefer a milder oil, avocado oil works nicely.

Seasonings

Italian seasoning, paprika and onion powder fill out the flavor and help the potatoes take on a pretty golden color. Dried rosemary or thyme can stand in for the Italian seasoning, and a pinch of smoked paprika adds a subtle smoky warmth.

How to make it

Step 1. Preheat the pan with the oven

Slide a large rimmed sheet pan onto the center rack and preheat the oven to 425F with the pan inside. Heating the pan along with the oven is my favorite secret for crunchy potatoes. The instant the potatoes touch that hot surface, the bottoms begin to sear, much like they would in a cast iron skillet.

Step 2. Cut and dry the potatoes

Scrub the potatoes well and cut them into uniform 1 inch chunks. Lay them out on a clean dish towel and blot them as dry as possible. Leftover water becomes steam in the oven, and steam keeps the edges from getting crunchy.

Step 3. Season the potatoes

Put the potatoes in a big bowl, drizzle in the oil and toss until each piece is glossy. Add the paprika, Italian seasoning, onion powder, garlic powder, pepper, salt and half the Parmesan, then toss again until everything looks evenly coated.

Step 4. Roast the first round

Using oven mitts, take the hot pan out and quickly spread the potatoes over it in one layer, with as many cut sides facing down as you can manage. Listen for the sizzle. Roast 20 minutes and do not stir, so the undersides can turn a deep golden brown.

Step 5. Garlic on, then turn them

Take out the pan and scatter the fresh garlic over the potatoes. Turn them with a thin metal spatula, scraping up any bits of crispy cheese clinging to the pan, and arrange them in one layer once more.

If some pieces stick at first, that is fine. Scrape firmly with the spatula, and those browned bits of cheese and potato that come loose are the best part of the whole pan. Tom calls them the cook’s treat and helps himself. If you are using two pans, swap their rack positions now so both brown evenly.

Step 6. Finish roasting

Put the pan back in the oven. Give it 15 to 20 more minutes, until the outsides are golden and crisp and a fork slips easily into the middle of a piece.

Step 7. Finish with Parmesan and parsley

If you are using butter, toss it with the hot potatoes first, then scatter on the remaining Parmesan and the parsley. The heat softens the cheese just enough that it sticks. Try a piece, add a little more salt if it needs it and serve them hot.

One note about doneness. Ovens and potatoes both vary, so go by how they look rather than what the timer says. You want deep golden edges, a few darker crunchy patches and insides that are fully tender when poked. If they are soft but still pale, give them another 5 minutes. Light colored potatoes nearly always just need a bit longer.

Common mistakes to avoid

• Overloading the pan. Potatoes piled on top of each other steam rather than roast. If the pan looks crowded, split them between two.
• Mismatched sizes. Big and small pieces together means some burn while others stay hard in the center.
• Not drying them. Damp potatoes brown slowly and never reach full crunch.
• Adding fresh garlic at the start. Minced garlic burns over a 40 minute roast and tastes bitter. Wait until the flip.
• Fussing with them. Each stir interrupts the browning. A single flip is all they need.
• An oven that is not hot enough. Below roughly 400F, you get soft, pale potatoes instead of crisp ones.

Make ahead and storage

Make ahead. On a hectic day, you can cut the potatoes a full day early and store them covered in cold water in the refrigerator. Drain and dry them thoroughly before seasoning. The spices and Parmesan can also be mixed in advance and kept in a little jar.

Fridge. Sealed in a container, leftovers last up to 4 days in the fridge, and they make terrific breakfast potatoes.

Freezer. Freeze roasted potatoes spread out on a sheet pan, then transfer them to a freezer bag and keep for up to 3 months. They soften a bit once frozen, so I save those for breakfast hash or a casserole.

Reheating. For the best crunch, give them 10 to 12 minutes in a 400F oven. An air fryer set to 375F does it in 5 to 7 minutes. Avoid the microwave if possible, since it leaves them soft and a little rubbery.

My favorite way to use leftovers is a quick breakfast skillet. I warm the potatoes in a pan with a pat of butter, crack in a few eggs and scatter some cheese over the top. Tom and I have a hearty breakfast in about 10 minutes.

Variations

It is easy to switch these up depending on what is in your pantry and what you plan to serve alongside.

• Ranch style. Use 1 tablespoon of dry ranch seasoning in place of the Italian seasoning.
• Rosemary and garlic. Add 1 tablespoon of chopped fresh rosemary when you add the fresh garlic. Mine comes straight from the pot by the back door.
• Fully loaded. Pile crumbled bacon, shredded cheddar, sliced scallions and a spoonful of sour cream on the finished potatoes.
• Lemon and herb. Brighten them at the end with some grated lemon zest and a squeeze of juice.
• A little heat. Mix a pinch of red pepper flakes, or 1/4 teaspoon of cayenne, in with the spices.
• Air fryer. Cook half the recipe at a time. Set it to 400F and allow 18 to 22 minutes, giving the basket a shake at the halfway mark.

What to serve with it

These are my standby side for almost any dinner. Serve them with meatloaf, burgers, roast chicken, baked thighs, grilled steak or pork chops taken to 145F. At the holidays they make an easy, well loved stand in for mashed potatoes beside a glazed ham or a beef roast.

To fill out the plate, add something green. Roasted asparagus, broccoli or green beans all work, as does a crisp salad with a light vinaigrette. If you want everything done at once, put the broccoli or beans on a second sheet pan for the final 15 to 20 minutes.

They also make a fun party snack. Set them out warm with toothpicks and a few sauces for dipping, such as ranch, garlic aioli or warm marinara. The grandkids go wild for them served this way, and they vanish as fast as a bag of chips.
