Hasselback Potato Recipe

Every year it sneaks up on us. Or maybe sprints is more like it.

It’s less shocking if snow’s been on the ground for awhile. But some years the ground we walk on has yet to turn from brown to white, and it’s those years that it arrives with a jolt.

It = the first day of winter + the winter holidays + the new year. All around the speedy corner.

We’re really and truly just 5 days away from the first official day of winter and 8 days from Christmas.  !!!🎄

Which means soooo many things. But since this is a dedicated space for foodies…


Hasselback Potatoes as the star side dish

Being that we’re a foodie place, we’re gonna talk food and just leave all the unfinished shopping + wrapping behind.

Every holiday season, we do some ridiculous turkey hoarding and we’re not shy about it.

We’ve been roasting big birds for alltheparties for 15 years now. That’s not all…we buy extra turkeys on sale and…um…bury them in the snow outside. Because who has room in their freezer for 2 extra large turkeys?

One year we went to dig up a big bird and couldn’t find the spot we’d stashed it in. Shoveling snow for turkeys like Where’s Waldo? That’s us. I think it was spring when it finally surfaced. Still frozen and ready for Easter 😅

But aside from turkeys and hams and all the roasts, the most fun part of holiday meals = glorious side dishes.


How to make hasselback potatoes in casserole form

Most of us can agree that potatoes reign supreme when it comes to holiday side dishes. Whether it’s Russets, Goldens, or Reds…whether mashed, roasted, or slow-cooked…potatoes are the ultimate holiday comfort dish.

After all, potatoes are the 9th wonder of the world.

Given that status, it’s no wonder(!) dishes like Slow Cooker Garlicky Mashed Potatoes and Crispy Smashed Red Potatoes are instant crowd favorites during holiday season and beyond.


Why you’ll love these hasselback potatoes

This holiday season, I’m not only dishing up beloved Make-Ahead Mashed Potatoes and the all-time super fabulous Sweet Potato Casserole with Brown Sugar Crumble.

I’m branching out in spud town and having a potato party with this Hasselback Roast Potato Casserole.

Here’s what this irresistible dish has going for it:

  1. Hasselback is just a fun thing to say.
  2. It’s crazy delicious. As in, crispy on the edges and tender throughout the center.
  3. You know your family and friends will be floored by your potato prowess.
  4. Pssst…this dish is surprisingly easy to pull off.

Cheesy Hasselback Potatoes are the way to go

If you have a mandolin (highly recommended) then your job is cut out for you. Literally 😋

If you don’t own one and prefer not to get one, a sharp knife will do the trick with a bit of elbow grease.

Once the potatoes are peeled and sliced…it’s all an easy downhill ride from there. Just throw on the herbs/seasonings and bake. Do allow for the usual potato bake time. Sprinkle on your cheese and toppings.

Hear the ooohs and aaahhs. Accept it; receive it. You’ll probably be asked to make this dish every year from now on.

  • 3 TB salted butter, melted
  • 3 TB extra virgin olive oil
  • 4 lbs russet potatoes, washed and peeled
  • 1 medium onion, chopped
  • 5 cloves garlic, chopped
  • kosher salt and freshly ground black pepper
  • ½ cup freshly shredded parmesan cheese
  • 3 TB thinly sliced green onions


  • Preheat oven to 375F with rack on middle position. In a bowl, whisk together the melted butter, olive oil, and 1 1/4 tsp kosher salt + 1/2 tsp freshly ground black pepper. Brush bottom of a 9-inch baking dish with a bit of butter mixture; set the remaining mixture aside.
  • Slice potatoes thinly and evenly cross-wise (for fastest and most even results, use a mandolin to slice potatoes. A sharp knife will work, too.)
  • Arrange potato slices upright (vertically and somewhat tightly) in prepared dish. Wedge chopped onions and garlic throughout potatoes. Brush with butter mixture, reserving 1/4 cup for later.
  • Bake 1 hour uncovered. Brush on the reserved 1/4 cup butter mixture and continue baking another 30 minutes until top is lightly browned. If it starts browning too quickly, cover loosely with foil.
  • Sprinkle top with shredded parmesan cheese and green onions. Bake 5-10 minutes until cheese is golden and melted. If desired, sprinkle top with a light dusting of kosher salt and black pepper. Serve immediately.


This dish comes together quickly once the potatoes are sliced. A mandolin can get the job done in 5-10 minutes. Be sure to allow enough time to bake. Dish is best when served hot and fresh from oven. Feel free to experiment with your favorite garnishes...crumbled bacon, other cheeses, and other herbs. It will be delicious any way you make it!

    Three things I love about this recipe-
    1. Russet potatoes. Easy to find and inexpensive!
    2. No fancy slicing potatoes three quarters of the way down!
    3. It’s a casserole!
    Enough said! This is THE PERFECT POTATO RECIPE!

    Do you think Yukon Golds will hold up well in this recipe? Only asking because I bought a bag from Costco and you know how that can get… lol. Thank you! Really excited to make this for Thanksgiving.

      Lynn, I absolutely know what you mean about Costco – LOL. Yes, you can use the Yukon potatoes, as they’re waxy enough to hold up well. Enjoy!

    I want to make this for thanksgiving but might have to cook ahead due to limited oven space/having to travel does it reheat well?

      • chewoutloud

      You can reheat, but do it in the oven uncovered, placed on upper middle rack to ensure that the top can re-crisp. Enjoy! 🙂
