Crispy Hashbrowns on a Blackstone Griddle

Hashbrowns are one of those things the Blackstone does better than almost anything else in the kitchen. The wide, flat surface means you can spread shredded potatoes in a thin, even layer across the whole cooking zone, and the steel gets hot enough to develop that crackling golden crust that’s impossible to replicate in a nonstick pan.

The key is removing moisture from the potatoes before they hit the griddle. Wet potatoes steam. Dry potatoes crisp.

Ingredients

• 2 lbs russet potatoes (about 3–4 medium potatoes)
• 1½ tsp kosher salt, divided
• ½ tsp black pepper
• ½ tsp garlic powder
• ½ tsp onion powder
• 2–3 tbsp neutral oil or butter (or a mix of both)

Optional add-ins:

• ½ cup diced onion, cooked until soft
• ½ cup diced bell pepper
• 2 cloves garlic, minced
• Fresh chives or green onion for serving

Instructions

Step 1: Shred the potatoes. Peel and shred potatoes using the large holes of a box grater or a food processor with a shredding attachment. Work quickly — potatoes oxidize and turn gray fast. That’s fine for cooking, but if it bothers you, shred into a bowl of cold water.

Step 2: Remove the moisture. This is the most important step. Place shredded potatoes in a clean kitchen towel, gather the corners, and wring out as much liquid as possible over the sink. Do it twice. The more moisture you remove, the crispier the result. Season with 1 tsp salt and let sit 5 minutes, then wring out again — salt draws out additional water.

Step 3: Season. Transfer dried potatoes to a bowl and toss with remaining ½ tsp salt, black pepper, garlic powder, and onion powder.

Step 4: Preheat the Blackstone to medium-high (375–400°F). Add 2 tbsp of oil or butter to the cooking zone and let it heat until shimmering.

Step 5: Add the potatoes. Spread shredded potatoes in an even layer across the cooking zone, about ¼–½ inch thick. Press down firmly with a spatula to create maximum contact with the steel. Don’t touch them for 6–8 minutes.

Step 6: Check the crust. Lift one corner with a spatula to check the color. You want deep golden brown — almost amber — before flipping. If it’s light golden, give it another 2 minutes. A deep crust releases cleanly from the griddle; a pale one will stick and tear.

Step 7: Flip and finish. Flip the hashbrowns in sections — they won’t hold together as one piece and that’s fine. Press down again with the spatula. Cook another 5–6 minutes until the second side is golden and crispy. Serve immediately.

The Moisture Rule

Potatoes are mostly water. When that water hits a hot griddle, it turns to steam — and steam is the opposite of crispy. The double-wring method (wring, salt, wring again) removes enough moisture to make a real difference. You’ll be surprised how much liquid comes out.

If you have time, spread the shredded potatoes on a clean kitchen towel and let them air-dry for 15–20 minutes before wringing. Even more moisture removed, even crispier result.

Fresh vs. Frozen Shredded Potatoes

Fresh (shredded yourself): More work, better flavor, crispier result when moisture is properly removed. Russets are the best variety — high starch, low moisture, and they develop a better crust than waxy potatoes like Yukon Golds.

Frozen shredded hashbrowns: Convenient and still produce good results on a Blackstone. Thaw overnight in the fridge and squeeze out excess liquid before cooking. They won’t get quite as crispy as fresh, but they’re a solid weekday shortcut.

Loaded Hashbrowns

The Blackstone’s size makes it easy to build loaded hashbrowns. Use the heat zones:

1. Cook diced onions and peppers on the cooler side until softened
2. Cook hashbrowns on the hot side
3. When hashbrowns are almost done, top with cooked vegetables and shredded cheese, cover with a basting dome until the cheese melts
4. Finish with sour cream, chives, and hot sauce

Variations

Breakfast hashbrown skillet: After flipping, push hashbrowns to a lower heat zone and use the hot zone to fry eggs or scramble them. Everything finishes at the same time.

Cheesy hashbrowns: Add shredded cheddar on top after flipping, cover with a basting dome for 60 seconds until melted.

Spicy hashbrowns: Add ½ tsp cayenne and a pinch of crushed red pepper to the seasoning mix. Top with jalapeños and hot sauce.

Sweet potato hashbrowns: Substitute sweet potatoes for russets. They won’t get as crispy but the flavor is excellent. Reduce the heat slightly — sweet potatoes burn faster than russets.

Frequently Asked Questions

Why aren’t my hashbrowns getting crispy on the Blackstone? Almost always too much moisture. Shredded potatoes need to be thoroughly dried before they hit the griddle — use a kitchen towel and wring hard, twice. Also make sure your griddle is fully preheated to medium-high before adding the potatoes, and don’t flip too early. Let the crust fully develop before touching them.

Do you need to peel potatoes for hashbrowns? Peeling is recommended for a more uniform texture and better crust. Potato skin doesn’t crisp the same way the starchy interior does. That said, you can leave the skin on if you prefer — it won’t ruin the hashbrowns, just changes the texture slightly.

Can you use frozen hashbrowns on a Blackstone? Yes. Thaw them overnight in the fridge and squeeze out as much liquid as possible before cooking. They won’t get quite as crispy as fresh-shredded, but the Blackstone still produces a better result than a stovetop pan because of the even, wide surface.

What type of potato is best for hashbrowns? Russet potatoes. High starch content and lower moisture than other varieties — exactly what you want for a crispy crust. Yukon Gold potatoes work but are waxier and produce a softer, less crispy result.

How do you keep hashbrowns from sticking to the Blackstone? Make sure your griddle is well-seasoned and fully preheated before adding oil, and add enough oil to cover the cooking zone. Then don’t try to flip too early — a crust that’s properly formed will release cleanly from the steel. If it’s sticking, it needs more time.

How long do hashbrowns take on a Blackstone? 15–20 minutes total: 6–8 minutes on the first side to develop a deep golden crust, then 5–6 minutes on the second side. The exact time depends on how thick you spread them and how hot your griddle runs.

Can you make hashbrowns ahead of time on the Blackstone? They’re best fresh off the griddle — the crust softens as they sit. If you need to prep ahead, shred, dry, and season the potatoes and refrigerate them up to a day in advance. Cook right before serving.
