French Fries on Blackstone: Crispy Flat-Top Fries Two Ways

French fries on the Blackstone aren’t deep-fried fries — but they’re not trying to be. What you get on the flat-top is something between a fried potato and a roasted potato: crispy, golden, with charred edges and a creamy interior. Two methods below, depending on what you want and how much time you have.

Method 1 (Smash Fries): Par-cook potatoes, smash flat on the griddle, and fry in oil until the cut surfaces crisp up. This produces the crunchiest result — more surface area, more crust.

Method 2 (Shoestring Fries): Cut potatoes thin, par-cook, and fry on the griddle. A faster, more classic-looking fry.

Both work. Both are good. Method 1 has better texture. Method 2 looks more like an actual french fry.

Method 1: Smash Fries (Best Crunch)

Ingredients

• 2 lbs baby potatoes (Yukon Gold or red)
• 3 tbsp avocado oil or vegetable oil
• 1 tsp garlic powder
• 1 tsp smoked paprika
• ½ tsp onion powder
• 1 tsp kosher salt
• ½ tsp black pepper
• Fresh chives and parsley for topping (optional)
• Flaky sea salt for finishing

Instructions

Step 1: Par-cook the potatoes. Boil baby potatoes in salted water until just fork-tender, about 15 minutes. Don’t overcook — they should hold their shape when you pick them up. Drain and let them steam dry for 5 minutes.

Step 2: Preheat the Blackstone. Set to medium-high (400–425°F). Add a generous drizzle of avocado oil across the cooking zone.

Step 3: Smash. Place potatoes on the oiled surface and immediately press each one flat with a burger press or the bottom of a heavy mug. Press to about ¼-inch thickness — enough to flatten, not so hard you crumble them.

Step 4: Season. Mix garlic powder, paprika, onion powder, salt, and pepper. Sprinkle over the smashed potatoes. Drizzle with a little more oil.

Step 5: Fry without moving. Cook 5–6 minutes without touching them. The bottom needs to form a crust before you try to flip. When you can slide a spatula cleanly under them and the edges look deep golden, flip.

Step 6: Second side. Cook another 4–5 minutes until the second side is equally golden. Drizzle with a little more oil if the griddle looks dry.

Step 7: Finish. Slide off the griddle. Hit with flaky sea salt immediately. Top with chives and parsley if using.

Method 2: Shoestring Fries

Ingredients

• 2 lbs russet potatoes
• 3 tbsp avocado oil
• 1 tsp kosher salt
• ½ tsp black pepper
• ½ tsp garlic powder
• ½ tsp smoked paprika

Instructions

Step 1: Cut the potatoes. Cut into ¼-inch thick matchsticks (shoestring style). Keep them as uniform as possible for even cooking. Soak in cold water for 20 minutes, then drain and pat completely dry with towels. Wet potatoes won’t crisp — this step matters.

Step 2: Par-cook (optional but recommended). Microwave the dried potato strips in a bowl for 4–5 minutes until slightly softened but not fully cooked. This gives you a head start on the interior without the exterior burning. Alternatively, boil for 3 minutes, drain, and pat dry again.

Step 3: Preheat and oil. Set Blackstone to medium-high (400–425°F). Add a generous layer of avocado oil.

Step 4: Cook in batches. Add potatoes in a single layer — don’t pile them. Cook 4–5 minutes without stirring until the bottom side is golden. Toss and cook another 3–4 minutes, tossing every minute, until golden and crispy all over.

Step 5: Season and serve. Season immediately out of the griddle — salt sticks better when they’re hot. Serve right away; they soften quickly.

Frequently Asked Questions

Can you cook french fries on a Blackstone griddle? Yes. The flat-top isn’t a deep fryer, but it produces excellent crispy potatoes — more like high-heat roasted fries with charred edges. The smash method (par-cook, flatten, fry) gives the best texture. The key is high heat, plenty of oil, and not crowding the surface.

Why aren’t my griddle fries getting crispy? Three causes: the potatoes weren’t dry enough (moisture prevents crisping), the griddle isn’t hot enough (need 400°F+), or you’re moving them too soon. Let them sit undisturbed for at least 4–5 minutes on the first side before flipping.

Do you need to par-cook potatoes for griddle fries? Yes, for both methods. Raw potato takes too long to cook through at the temperatures needed to crisp the outside. Par-cooking (boiling or microwaving) gets the interior started so you’re only finishing the exterior on the griddle. Skipping it gives you a burnt outside and raw inside.

What oil is best for french fries on the Blackstone? Avocado oil or vegetable oil — high smoke point, neutral flavor. Don’t use olive oil at high heat (low smoke point, will smoke heavily and develop off flavors). Don’t use butter alone (burns at fry temps). Avocado oil is the best choice.
