Crispy Garlic Parmesan Hashbrowns with Spicy Dip Tips, FAQ & printable recipe

Tips for success

For an extra-crispy crust, press a bit more grated parmesan onto the patties just before they hit the oil. The cheese will melt and crisp into a lacy, golden shell that shatters with each bite. If you have time, let the formed patties rest in the refrigerator for 15 minutes before frying—this helps them hold together even better.

To keep the oil at the right temperature, use a deep-fry thermometer and adjust the heat as needed. If the oil gets too hot, the crust will brown too quickly while the inside remains raw.

If it's not hot enough, the hashbrowns will absorb oil and become greasy. Also, don't crowd the pan—fry in batches to maintain the temperature and ensure even cooking.

Variations

• Cheesy Herb Hashbrowns: Add 2 tablespoons of chopped fresh chives or parsley to the potato mixture, and replace the parmesan with a mix of parmesan and cheddar. The herbs add freshness, and the cheddar brings a gooey, savory note.
• Spicy Jalapeño Hashbrowns: Stir 2 tablespoons of finely chopped pickled jalapeños into the potato mixture, and add a pinch of cayenne to the parmesan coating. The heat pairs well with the cool dip.
• Bacon and Onion Hashbrowns: Cook 2 slices of bacon until crisp, crumble, and mix into the potatoes along with 1/4 cup finely chopped caramelized onions. The smoky, sweet flavors elevate the hashbrowns to a hearty side.
• Sweet Potato Hashbrowns: Substitute half of the russet potatoes with peeled sweet potatoes. Parboil them separately for 8 minutes, then grate and mix with the russets. The sweetness contrasts nicely with the garlic and parmesan.

Storage and make-ahead

Fridge

Store cooked hashbrowns in an airtight container in the fridge for up to 3 days. Reheat in the oven or air fryer to restore crispness.

Freezer

Freeze cooked hashbrowns in a single layer on a baking sheet, then transfer to a zip-top bag for up to 2 months.

Reheat

For best results, reheat frozen or refrigerated hashbrowns in a toaster oven or air fryer at 375°F (190°C) for 5-7 minutes until hot and crispy.

Store leftover hashbrowns in an airtight container in the refrigerator for up to 3 days. To reheat, place them on a baking sheet in a 375°F (190°C) oven for 5-7 minutes, or use a toaster oven or air fryer for a few minutes until crisp.

Avoid microwaving, as it will make them soggy. The dip can be refrigerated separately for up to a week.

You can prepare the potato mixture and form the patties up to a day ahead. Place them on a parchment-lined baking sheet, cover, and refrigerate. When ready to cook, proceed with frying—you may need to add a minute to the cooking time if they are cold. The dip can also be made ahead and stored in the refrigerator for up to a week.

Serving ideas

Serve these hashbrowns as a side dish for breakfast or brunch, alongside eggs, bacon, or a fresh salad. They also make a fantastic appetizer for parties—cut them into smaller wedges and serve with the dip for easy finger food.

The crunchy texture and savory flavor pair well with a variety of mains, from grilled steak to roasted chicken.

For a fun twist, use the hashbrowns as a base for eggs benedict or top them with a poached egg and hollandaise sauce. They also work well as a burger topping or as a hearty snack on their own.

The spicy dip is versatile, too—try it with fries, onion rings, or as a sandwich spread. However you serve them, these hashbrowns are sure to be a hit.

Crispy Garlic Parmesan Hashbrowns with Spicy Dip

Prep 20 minCook 20 minTotal 40 minServes 4

Ingredients

• 5 large russet potatoes (about 2 1/2 lb)
• 1 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper
• 1/2 cup finely grated parmesan cheese
• 1/2 cup vegetable oil, for frying
• 1/2 cup mayonnaise
• 2 tbsp ketchup
• 1 tbsp hot sauce
• 1/2 tsp garlic powder

Instructions

1. Place the potatoes in a large pot and cover with cold water. Bring to a boil and cook for 10-12 minutes, until a knife slips in with slight resistance. Drain and let cool until just warm. Peel the potatoes (skins slip off easily) and grate them on the large holes of a box grater into thick shreds. Transfer the shreds to a clean kitchen towel or cheesecloth and squeeze firmly to remove as much starch and moisture as possible.
2. In a large bowl, combine the grated potatoes with garlic powder, salt, black pepper, and half of the grated parmesan. Toss gently with your hands until the seasoning and cheese are evenly distributed. The mixture will be slightly sticky but should hold together when pressed.
3. Divide the potato mixture into 4 equal portions. Shape each portion into a compact patty about 1/2 inch thick and 4 inches wide. Press the remaining parmesan onto both sides of each patty, creating a thin crust. Place the patties on a plate lined with parchment paper.
4. In a large skillet, heat the vegetable oil over medium-high heat until shimmering, about 350°F (175°C). The oil should be about 1/4 inch deep. To test, drop a small piece of potato into the oil — it should sizzle immediately.
5. Carefully place the patties into the hot oil, working in batches if needed to avoid crowding. Fry for 3 minutes per side, until the parmesan crust is deep golden and crackling. Use tongs to flip gently. The interior should be cooked through and fluffy.
6. Transfer the fried hashbrowns to a wire rack set over a baking sheet to drain excess oil. Keep them warm in a low oven (200°F / 95°C) while frying the remaining batches, if any.
7. In a small bowl, whisk together the mayonnaise, ketchup, hot sauce, and garlic powder until smooth. Adjust the heat to taste with extra hot sauce if desired.
8. Serve the hashbrowns hot, with the spicy dip on the side for dunking. Enjoy immediately for the best crunch.
