Blackstone smashed potatoes earn their spot fast: crisp, lacy edges on the outside, a creamy middle that stays soft, and enough buttery garlic flavor to make the whole tray disappear before the main dish is even on the table. The griddle does what the oven can’t quite match here. It gives you deeper browning in less time, plus that shattering crust that makes smashed potatoes worth the extra few minutes of hands-on cooking.
The trick is starting with potatoes that are fully tender before they ever hit the hot surface. If they’re even a little undercooked, they’ll crack instead of flattening cleanly, and you’ll lose the fluffy center that makes this dish work. A mix of oil and butter helps with both browning and flavor, while the garlic cooks around the potatoes instead of directly under them so it perfumes the griddle without burning in the first minute.
Below, I’m walking through the small details that matter most: how much pressure to use when smashing, when to flip, and how to pile on the toppings without softening the crust you just built.
The potatoes got those crunchy edges I was hoping for, and the garlic butter on the Blackstone made them taste like restaurant potatoes. I topped half with cheddar and bacon, and the whole pan was gone in minutes.
Save these Blackstone smashed potatoes for the next time you want crispy griddle potatoes with a buttery garlic crust and creamy centers.
The Griddle Trick That Keeps the Centers Creamy While the Edges Crisp
The biggest mistake with smashed potatoes is rushing the smash before the potatoes are ready. When they’re tender all the way through, they flatten into rustic rounds instead of splitting apart, and that gives you the contrast you want: crisp bottom, soft middle. On a Blackstone, that contrast gets even better because the hot surface dries the exterior quickly while the butter and oil help the edges fry instead of steam.
Space matters too. If the potatoes crowd each other, they trap moisture and soften before they brown. Give each one room, and don’t move them the second they hit the griddle. The first side needs uninterrupted contact to build that deep golden crust.
What the Butter, Oil, and Garlic Are Each Doing Here
- Baby potatoes — Small potatoes hold their shape after boiling and smash into neat rounds without falling apart. Yukon golds are especially good here because they stay creamy inside, but red potatoes work too if that’s what you have.
- Olive oil and butter — Oil raises the smoke point, and butter gives you that rich, browned edge. Use both; butter alone can burn too fast on a hot griddle, while oil alone loses some of the flavor that makes these taste finished.
- Garlic — Adding the minced garlic around the potatoes instead of under them keeps it fragrant instead of bitter. It toasts just enough in the fat to flavor the potatoes without turning black.
- Sour cream, cheddar, chives, and bacon — These toppings turn the potatoes into loaded smashed potatoes, but they also change the texture fast. Add them after the crisping is done so the crust stays intact under the cool, creamy toppings.
Getting the Smash, the Sear, and the Flip Right
Boil Until the Fork Slides In Easily
Start by boiling the baby potatoes until a fork slides in with no resistance, about 15 to 20 minutes depending on size. Drain them well and let the surface steam off for a few minutes; wet potatoes hit the griddle and sputter, and that extra moisture works against browning. If a potato feels firm in the center, leave it in the pot a little longer instead of trying to force the smash.
Press Once, Then Leave Them Alone
When the griddle is hot, add the oil and butter, then place the potatoes down and smash them with a heavy spatula or masher until they’re about half an inch thick. Press firmly enough to crack the skin and spread the potato, but don’t turn them into a mashy disc. The edges should look ragged; that’s where the crunch comes from. Scatter the garlic around the potatoes once they’re smashed so it can sizzle in the fat.
Let the First Side Build a Real Crust
Give the first side 6 to 7 minutes without disturbing it. You’re waiting for deep golden bottoms and crisp edges that release with a spatula, not pale potatoes that still cling to the griddle. If they stick, they need another minute; forcing them early tears the crust off and leaves you with soft spots. Flip carefully and cook the second side until it picks up the same color, another 5 to 6 minutes.
Season and Top at the End
Salt and pepper go on once both sides are crisp so the seasoning stays on the potato instead of dissolving into the butter. Add sour cream, cheddar, chives, and bacon bits right before serving. That keeps the toppings bright and the bottoms crisp, which is the whole point of cooking them on the Blackstone in the first place.
How to Adapt These for Different Toppings and Dietary Needs
Dairy-Free Smashed Potatoes
Use all olive oil instead of the butter and finish with dairy-free sour cream or skip the creamy topping altogether. You’ll lose a little richness, but the griddle browning still gives you plenty of flavor.
Vegetarian Loaded Potatoes
Leave off the bacon and add extra chives, more cheddar, or even a spoonful of caramelized onions. You still get the same crispy base, but the topping tastes a little richer and less smoky.
Extra-Crispy Griddle Potatoes
After smashing, let the potatoes sit on the griddle a minute longer before flipping. That extra time deepens the crust, but only works if the heat stays at medium-high and the pan isn’t crowded.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days. The crust softens, but the flavor holds up well.
- Freezer: These freeze poorly once topped with sour cream and cheese. If you want to freeze them, freeze the plain cooked potatoes first on a tray, then reheat and top after warming.
- Reheating: Reheat on a skillet, griddle, or in a hot oven until the edges crisp back up. The common mistake is microwaving them, which turns the potatoes soft and steamy instead of bringing back that browned crust.
