Crispy, golden, and loaded with garlic and cheesy flavor — these Garlic Parmesan Hashbrowns are a serious upgrade to regular hashbrowns. They’re perfectly seasoned, easy to make, and taste restaurant-quality at home!
Ingredients
- 5 large russet potatoes, peeled and diced into big chunks
- Salt to taste
- ½ tsp black pepper
- 1 tbsp garlic powder
- 2 tbsp cornstarch
- 1 egg
- ¼ cup freshly grated Parmesan cheese
- Oil for frying
- Extra Parmesan for sprinkling on top
Method
- Partially Boil the Potatoes Add the diced potatoes to a saucepan with salted water. Bring to a boil and cook until they are about 70% done (still slightly firm). Drain the water completely, then let the potatoes sit in the same pan for 10 minutes so all excess moisture evaporates.
- Shred & Season Grate the potatoes using a box grater. Transfer to a large mixing bowl. Add salt, black pepper, garlic powder, egg, cornstarch, and ¼ cup freshly grated Parmesan cheese. Mix everything thoroughly until well combined.
- Shape Lightly grease your hands with oil. Take portions of the mixture and form them into thin oval or patty shapes. Place on a parchment-lined tray.
- Freeze Freeze the shaped hashbrowns for 15–20 minutes until firm. This helps them hold their shape and get extra crispy.
- Fry Heat oil in a pan to 350°F (175°C). Fry the hashbrowns on medium heat for 4–6 minutes, flipping halfway, until deep golden brown and crispy on both sides.
- Finish Sprinkle with extra grated Parmesan cheese while still hot. Serve immediately.
Pro Tips for Extra Crispy Hashbrowns
- Russet potatoes give the best crispy texture.
- Removing as much moisture as possible (boiling + resting + grating) is the secret to crispiness.
- Don’t make the patties too thick — thinner ones cook evenly and get crunchier.
- Maintain steady oil temperature. Too hot will burn them; too cool will make them greasy.
- Freshly grated Parmesan melts and flavors much better than pre-shredded.
Serving Suggestions
Serve hot with eggs, bacon, ketchup, sour cream, or garlic aioli. They also make a great side dish for burgers or fried chicken.
These Garlic Parmesan Hashbrowns are crispy, cheesy, and incredibly addictive!
