Crispy Garlic Parmesan Hash Browns

These viral hash browns are crispy on the outside, tender in the middle, and loaded with savory garlic parmesan flavor. The potatoes are parboiled, grated, mixed with seasonings, cornstarch, egg, and freshly grated parmesan, then pan-fried until golden and crunchy. They’re perfect for breakfast, brunch, or as a crispy potato side dish with dinner.

Why You’ll Love This Crispy Hash Brown Recipe

I've been seeing versions of parmesan hashbrowns everywhere on Instagram Reels and TikTok, so I had to try making them. I took inspiration from the most viral videos and ended up creating this crispy garlic parmesan hashbrown recipe. They're everything I want in a homemade hashbrown; crisp, cheesy, salty, and golden brown, but still soft and fluffy in the center. The parmesan gives them a savory, slightly nutty flavor that makes them taste way better than plain hashbrowns.

This recipe uses russet potatoes because they’re starchy enough to crisp up really well. Parboiling them first gives the inside that tender texture, while squeezing out the moisture helps the outside fry up crispy instead of soggy. The quick freezer step also makes a big difference. It helps the patties firm up before they hit the oil, so they hold their shape and get that perfect crust in the pan. These two tricks are what I think set this recipe apart from the viral ones I've seen. 

Serve them with eggs, bacon, breakfast sandwiches, burgers, grilled chicken, or even just a little ketchup or sour cream on the side. Anyway you eat them, I know you'll love them!

Ingredients

• 4-5 russet potatoes
• ½ teaspoon onion powder
• ½ teaspoon garlic powder
• ½ teaspoon paprika
• ¼ teaspoon black pepper
• ¾ teaspoon salt
• 2 tablespoons cornstarch
• 1 egg
• ½ cup parmesan, freshly grated

How To Make Garlic Parmesan Hash Browns

Step 1: Parboil the Potatoes

Peel the potatoes and cut them in half. Place them in a pot of salted water, bring the water to a boil, and cook the potatoes for about 5 minutes. You want them slightly tender on the outside but not fully cooked. They should still be firm enough to grate without falling apart.

Step 2: Cool and Grate the Potatoes

Drain the potatoes right away and let them cool completely. This step is important for the texture. If the potatoes are too warm when you grate them, they can turn gummy and soft. Once cooled, grate the potatoes using the large holes of a box grater.

Step 3: Squeeze Out the Moisture

Transfer the grated potatoes to a clean kitchen towel and squeeze out as much moisture as possible. The potatoes should be as dry as you can get them. Removing the moisture is one of the biggest keys to making crispy parmesan hashbrowns instead of soft, soggy ones.

Step 4: Mix the Hashbrown Mixture

Place the dried grated potatoes in a bowl. Add the egg, cornstarch, onion powder, garlic powder, paprika, black pepper, salt, and freshly grated parmesan.

Gently mix everything together until combined. Try not to mash the potatoes too much. You want the mixture to hold together while still keeping some texture from the grated potatoes.

Step 5: Shape and Freeze

Shape the potato mixture into thin oval patties and place them on a parchment-lined tray. Freeze the patties for 15-20 minutes, or until firm. This helps them hold their shape while frying and makes them easier to handle.

Step 6: Fry Until Golden and Crispy

Heat oil in a pan over medium heat. Once the oil is hot, add the potato patties in a single layer. Cook them without moving for 4-5 minutes, or until the bottoms are golden brown and crispy. Flip and cook the other side until equally crisp and golden.

Step 7: Serve

Transfer the parmesan hashbrowns to a paper towel-lined plate if needed, then serve hot. They’re best right out of the pan while the outside is still crunchy and the parmesan is warm and savory.

My Tested Expert Tips For The Best Crispy Parmesan Hash Browns

• Use russet potatoes. Russets are the best potatoes for crispy hashbrowns because they’re high in starch and low in moisture compared to waxy potatoes. That starch helps the patties bind together and gives the outside a better golden crust.
• Don’t fully cook the potatoes. The goal is to parboil them just enough so they’re slightly tender but still firm. If the potatoes get too soft, they’ll be harder to grate and can turn mushy when mixed.
• Cool the potatoes completely before grating. This is one of those steps that seems small but really matters. Warm potatoes release more moisture and can become gummy. Cooling them helps the grated texture stay light and separate.
• Squeeze out as much water as possible. Moisture is the enemy of crispy hashbrowns. After grating the potatoes, wrap them in a clean towel and squeeze hard until very little liquid comes out. The drier the potatoes, the crispier the hashbrowns.
• Use freshly grated parmesan. Fresh parmesan cheese melts and crisps better than the shelf-stable grated kind. It also has a stronger, nuttier flavor that makes these hashbrowns taste more savory and homemade.
• Don’t overmix the potato mixture. Mix gently until everything is just combined. Overmixing can break down the potatoes and make the patties dense instead of crisp and tender.
• Shape them thin. Thin patties crisp up better than thick ones. If they’re too thick, the outside may brown before the center heats through. A thinner oval shape gives you more crispy edges and a better texture.
• Freeze before frying. The short freezer time helps the patties firm up so they don’t fall apart in the pan. You don’t need to freeze them solid, just long enough for them to feel firm and easier to handle.
• Make sure the oil is hot before adding the patties. If the oil isn’t hot enough, the potatoes will absorb it and turn greasy. The patties should sizzle when they hit the pan.
• Don’t move them too early. Let the hashbrowns cook undisturbed for 4-5 minutes before flipping. Moving them too soon can break the crust before it has a chance to form.
• Cook in batches if needed. Overcrowding the pan lowers the oil temperature and makes it harder for the hashbrowns to crisp. Give each patty enough room so the edges can brown properly.
• Season the potatoes well. Potatoes need salt to bring out their flavor. The parmesan adds saltiness too, but the seasoning blend makes the hashbrowns taste balanced instead of flat.

Storage and Reheating Instructions

How To Store Leftover Parmesan Hash Browns

Let the hashbrowns cool completely, then transfer them to an airtight container and store them in the refrigerator for up to 4 days. Don’t store them while they’re still hot, or the trapped steam can soften the crispy coating.

How To Reheat Parmesan Hash Browns

For the crispiest texture, reheat the hashbrowns in a skillet over medium-low heat with a small drizzle of oil until hot and crunchy again. You can also reheat them in the air fryer at 375°F for 4-6 minutes, or until warmed through and crisp around the edges.

The oven works too, but the skillet and air fryer will give you the best texture. I don’t recommend microwaving unless you’re in a hurry since it warms them through but won’t bring back the crispy outside.

Garlic Parmesan Hashbrowns FAQs

What kind of potatoes are best for parmesan hashbrowns?

Russet potatoes are the best choice for parmesan hashbrowns because they’re starchy and crisp up well. They also have a fluffy texture inside, which gives the hashbrowns that perfect crispy-outside, tender-inside bite.

Why do you parboil the potatoes first?

Parboiling partially cooks the potatoes so the inside of the hashbrowns turns tender while the outside gets crispy in the pan. It also makes the potatoes easier to grate without fully cooking them into a soft, mashed texture.

Do I have to cool the potatoes before grating?

Yes, cooling the potatoes helps keep the texture right. If the potatoes are still hot when you grate them, they can turn gummy and release too much moisture. Letting them cool completely makes them easier to grate and helps the hashbrowns crisp better.

Why are my hashbrowns not crispy?

The most common reason is too much moisture in the potatoes. After grating, you need to squeeze out as much liquid as possible with a clean kitchen towel. Hashbrowns can also turn soft if the oil isn’t hot enough, the pan is overcrowded, or the patties are too thick.

Can I make these parmesan hashbrowns ahead of time?

Yes. You can shape the patties and freeze them for 15-20 minutes before cooking, or freeze them longer for future use. Once frozen firm, transfer them to a freezer-safe bag and cook them straight from frozen when you’re ready.

Can You Freeze Parmesan Hashbrowns?

Yes, but I recommend freezing the shaped, uncooked patties instead of freezing them after frying. Place the shaped patties on a parchment-lined tray and freeze until firm, then transfer them to a freezer-safe bag or container. When you’re ready to cook, fry the parmesan hashbrowns straight from frozen, adding a few extra minutes per side as needed until they’re golden, crispy, and hot in the center.

Can I air fry parmesan hashbrowns?

Yes, you can air fry them. Spray the patties well with oil and air fry at 375°F until golden and crispy, flipping halfway through. The texture may be slightly less rich than pan-fried hashbrowns, but they’ll still get crispy if the potatoes are dry enough.

Can I use pre-shredded parmesan?

Freshly grated parmesan is best for this recipe. Pre-shredded parmesan often has anti-caking ingredients that can affect how it melts and crisps. Fresh parmesan gives the hashbrowns better flavor and a better texture.

How do I keep the patties from falling apart?

Make sure the potatoes are squeezed dry, the egg and cornstarch are mixed in evenly, and the patties are frozen briefly before frying. Also, don’t flip them too early. Let the first side get golden and set before turning them.

What can I serve with parmesan hashbrowns?

These hashbrowns are great with eggs, bacon, sausage, breakfast sandwiches, burgers, steak, grilled chicken, or roasted vegetables. For dipping, try ketchup, sour cream, garlic aioli, ranch, spicy mayo, or marinara sauce.
