Crispy Garlic Parmesan Hashbrowns for Breakfast

These garlic parmesan hashbrowns are the breakfast side you didn’t know you needed. Par-boiled russet potatoes are shredded, squeezed dry, and mixed with egg, cornstarch, and a generous amount of parmesan, then pan-fried until the exterior shatters with a satisfying crunch.

The inside stays fluffy and steamy, with a savory garlicky flavor that pairs perfectly with eggs or a dollop of spicy mayo. Best of all, they come together in under 30 minutes, making them an achievable weekday treat or a weekend brunch star.

There’s something magical about a hashbrown that cracks when you bite into it. This recipe delivers that experience every time. The secret lies in par-boiling the potatoes first, which softens them enough to shred easily while keeping their structure intact.

After squeezing out every drop of moisture, the shreds are tossed with egg, cornstarch, and parmesan to create a batter that crisps up like a dream in hot oil. The result is a golden, craggy patty with a tender, steamy center. Serve them alongside your favorite breakfast proteins or stack them high with a fried egg on top.

Ingredients

Why this recipe works

Par-boiling the russet potatoes before shredding is a game-changer. It partially cooks the potatoes, so they soften just enough to shred without turning mushy. This step also helps the shreds hold their shape during frying, giving you those craggy, crispy edges that make hashbrowns so irresistible. The boiling also removes excess starch, which would otherwise make the patties gummy.

The combination of egg, cornstarch, and parmesan creates a coating that fries up shatteringly crisp. The egg binds the shreds, the cornstarch adds a delicate crunch, and the parmesan browns beautifully, adding a nutty, salty flavor.

Squeezing the shredded potatoes dry is equally important—any excess moisture turns to steam in the oil, preventing the crust from forming. Together, these techniques guarantee a hashbrown that’s crisp on the outside, fluffy on the inside, and packed with savory flavor.

Notes and substitutions

Russet potatoes are the best choice here because they’re high in starch and low in moisture, which yields a fluffy interior and a crispier crust. Yukon Golds can work in a pinch, but they’ll be slightly less crispy.

For the parmesan, use a fresh block and grate it yourself—pre-shredded varieties often contain anti-caking agents that prevent melting and browning. The egg acts as a binder, so don’t skip it.

A box grater or a food processor with a shredding disc both work well. After shredding, wrap the potatoes in a clean kitchen towel or cheesecloth and squeeze firmly—this step is non-negotiable. Use a heavy skillet like cast iron for even heat distribution, and make sure the oil is hot before adding the patties. If the oil isn’t hot enough, the hashbrowns will absorb oil and turn greasy instead of crispy.

• cornstarch: potato starch (use the same amount; helps with crispiness)
• garlic powder: 1 clove fresh garlic, finely minced (add with the egg)
• vegetable oil: canola oil or peanut oil (high smoke point for frying)
