What potatoes work best for Hasselback?
Russets get the crispiest edges and fluffiest centers. Yukon Golds are creamier and slightly less crisp, but still great. For the most consistent timing, pick potatoes that are similarly sized, around 8 to 10 ounces each.
How do I slice them without cutting all the way through?
Set the potato between two chopsticks or wooden spoon handles, then slice down until your knife hits the guides. Aim for 1/8-inch slices. Don’t stress if a few cuts are thicker. That just means more variety in crunch.
Why are my slices not fanning out?
Usually the cuts are too thick or the potato needs more time. Roast the plain, oiled potatoes first, then baste with butter. As they soften, you can gently coax the slices open with a brush or fork.
Do I have to peel them?
No. The skin helps the potato hold its shape and gets nice and crisp. Just scrub well.
Can I prep these ahead?
Yes. You can slice the potatoes up to 6 hours ahead and keep them submerged in cold water in the fridge. Longer soaks can leach a bit of starch and flavor, so don’t push it. When you’re ready to roast, rinse, then dry them very well so they roast, not steam.
How do I make them extra crispy?
Use russets, dry them well, don’t overcrowd the pan, and roast on the middle rack at a hot temp. A final 2 to 4 minutes under the broiler helps too, but watch closely, especially once the Parmesan is on.
