Blackstone smashed potatoes hit that sweet spot between crispy and creamy that keeps people drifting back for “just one more.” The bottoms get shatteringly crisp on the hot griddle while the centers stay fluffy and tender, and the garlic butter at the end gives every bite a glossy, savory finish.
The part that makes this version work is the dry, fork-tender potato and the hot, well-oiled surface. If the potatoes carry too much moisture from boiling, they steam instead of crisp. If the griddle isn’t hot enough, they stick before the crust sets. Once both of those pieces are right, the rest is easy: smash, leave them alone, flip when the edges are deeply browned, then finish with butter, garlic, and herbs so the flavor lands right on the crust.
Below you’ll find the timing cues that matter, the potato size that gives the best texture, and a few smart swaps if you’re cooking for a crowd or changing up the herbs.
The potatoes got incredibly crisp on the bottom and stayed fluffy inside, and the garlic butter soaked into all the ridges. I used a heavy mug to smash them and it worked perfectly.
Save these Blackstone smashed potatoes for the nights when you want a crispy griddle side with fluffy centers and garlic herb butter.
The Crisp Starts Before the Smash
The biggest mistake with smashed potatoes is rushing the dry-down after boiling. If the potatoes go onto the griddle still wet, the surface steams and softens before it ever has a chance to brown. Drain them well, then let the steam escape for a minute or two so the skins look matte instead of glossy. That small pause is what helps the edges turn crisp instead of leathery.
The other thing that matters is thickness. Smash them to about half an inch. Too thick and the centers stay dense while the outside overcooks; too thin and they fall apart before you get that fluffy middle. You want enough structure left in the potato that it holds together when you flip it.
- Baby or small potatoes — Yukon Golds give the creamiest center, while red potatoes hold their shape a little better. Keep the size consistent so they finish at the same time.
- Vegetable oil — This gives the griddle a stable layer of fat for crisping. A neutral oil works better than butter at this stage because butter would brown too fast before the potato crust sets.
- Butter, garlic, and rosemary — Melted butter added at the end coats the ridges without burning the garlic. If you add the garlic too early, it goes bitter on the hot surface.
- Chives and flaky salt — Add them after cooking so they stay fresh and sharp. The flaky salt gives you little bursts of seasoning right on the crust.
Getting the Potato Flat Without Breaking It Apart
Boiling to the Right Tenderness
Start the potatoes in salted water and cook until a fork slides in with only a little resistance. They should be tender enough to smash, but not so soft that the skins split open and the centers smear across the griddle. Drain them well and spread them out for a minute so surface moisture can evaporate. If they look wet, they’ll steam instead of crisp.
Smashing on the Hot Griddle
Brush the Blackstone with oil and let it get properly hot before the potatoes touch it. Set each potato down and press straight down with the bottom of a heavy mug or spatula until it flattens to a sturdy disk. Don’t drag the tool across the potato or you’ll tear the surface. A clean, firm press gives you the best edges and keeps the center intact.
Letting the Crust Set Before You Flip
Leave the potatoes alone for 8 to 10 minutes so the bottom can turn deep golden and release on its own. If you try to move them early, they usually stick because the crust hasn’t formed yet. Once the underside looks crisp around the edges and you can slide a spatula under it cleanly, flip and cook the second side until it matches.
Finishing With Garlic Butter
Stir the garlic and rosemary into the melted butter, then pour it over the potatoes near the end of cooking. That last minute is just enough to perfume the butter and glaze the crisp surfaces without scorching the garlic. Finish with chives, flaky salt, and sour cream right before serving so the potatoes stay crisp where they should and creamy where they matter.
How to Change the Seasoning Without Losing the Crunch
Dairy-Free Garlic Herb Potatoes
Skip the butter and finish with extra olive oil or a plant-based butter that can handle heat. You still get the crispy exterior and herb coating, but the flavor will be a little less rich and a little more clean and savory.
Cheesy Blackstone Smashed Potatoes
Sprinkle finely grated Parmesan over the potatoes during the last minute on the griddle. The cheese clings to the craggy edges and turns lacy and crisp, but it can brown fast, so add it only after the second side is mostly cooked.
Spicy Smoked Paprika Potatoes
Add smoked paprika and a pinch of cayenne to the butter mixture for a deeper, warmer finish. It changes the profile from classic herb butter to something a little bolder, and the smoked paprika plays especially well with the browned edges.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 4 days. The potatoes lose some crunch in the fridge, but the flavor holds up well.
- Freezer: Freezing isn’t the best choice here. The texture turns mealy after thawing, and the crisp edges never come back the same way.
- Reheating: Reheat on a skillet, griddle, or hot oven until the edges crisp again. The mistake to avoid is microwaving them first, which softens the crust before you have a chance to bring it back.
