Hasselback Potato Casserole

Have you made Hasselback potatoes? They’re a twist on baked potatoes created in Sweden–basically a fanned baked potato which increases the surface area available for seasoning. The insides are creamy while the exposed surfaces bake up to crispy deliciousness. But to make these for a crowd can be a bit daunting. I served this Hasselback Potato Casserole to my dinner club for brunch. They all wanted the recipe, especially once I explained how simple it was to make!

Tips for Making This Potato Casserole

I found the inspiration for this hasselback potatoes recipe on a fellow blogger’s site (see link below). Laura used a combination of  Yukon golds and sweet potatoes. I skipped the orange spuds so as not to scare off the picky hubby.

  • PRO-Tip: Use a mandoline to slice the pototoes, so they’re of a consistent size. This ensures all slices will be done baking at the same time.
  • Toss the potatoes and onions  in olive oil and season liberally with salt, pepper and fresh minced rosemary. Potatoes need plenty of salt or they will be bland! But over salting is not reversible.
  • Feel free drizzle on some butter, use thyme instead of rosemary, add some minced garlic or alternate the Yukon gold potato slices with sweet potato slices for a colorful potato medley.
  • This easy casserole can be made in any size you’d like, just poke your potatoes to make sure they’re tender before uncovering them for the browning stage.

This hasselback potato casserole is perfect for entertaining, serving for the holidays, or even weeknight dinners. My dinner club friends ALL wanted the recipe. A fine endorsement.

  6. No wonder people wanted this! It’s such a great variation on the hasselback potatoes, which are lovely but SO time consuming. Now I want to have these for dinner instead of what I have planned!

  7. Simple, beautiful and..potatoes! I think I could eat it alone 😀

  8. Beautiful, nice for a fancier dinner at home. Elegant.

  9. Hasselback potatoes are so much fun, aren’t they? Super flavor. Love this idea of this casserole — this is a better dish in many ways. Very creative — thanks.

  10. Liz, I’m honored that you did this adaptation of my recipe. (Mine is inspired by an Ottolenghi recipe, though we’ve both moved pretty far afield from his original.) Yours looks so elegant – I’m glad your guests and husband were as pleased with it as we were.

  11. Never heard of Hasselback potatoes but amazing idea. Love the crispy top and the presentation is great!

  13. These potatoes do make a good presentation and perfect for entertaining. I love this alternative to regular hasselback potatoes, which are great but can be a pain to make.

  14. Yes, please! I love potatoes and this casserole looks and sounds amazing!!

  15. Hasselbacks to the next level! Amazing, thanks so much, sharing on fb!

  16. What an amazing potato dish! Such a beautiful presentation. I’m going to have to try this with sweet potatoes since I just bought a 10 pound sack. They might cook a little faster. What do you think?

  17. Hasselback potatoes are gorgeous. I love that you turned it into a casserole in a nice dish. Looks great!

  18. Looks absolutely delicious! I’m going to volunteer to make this at my SILs for Christmas dinner!

  19. Liz, Hasselbeck potatoes always get raving reviews at our house – I love, love them – your version looks extremely elegant and utterly addictive! I should really make them again very soon!

  20. So simple looking Liz yet amazing flavour! Love potatoes in any way, but this recipe is worth making asap! If the book club says so…

  21. This is a MUST DO recipe. What would you suggest to replace rosemary?

  22. I’ve never tried such a casserole, but it’s definitely going to change immediately!
    It looks and sounds too good to pass 🙂

  23. Hi Liz, I love anything potato and this looks delicious. I can see why your dinner club friends wanted the recipe.

  24. I’ve seen these potatoes all over the internet but figured they were too complicated to tackle. Thank you for sharing how simple they are to pull together!

  25. Lizzy,
    I’ve never had hasselback potatoes before. They look yummy.

  26. Clap clap clap:) Fantastic recipe, and using your instructions this can be prepared rather quickly. Great tip, using the mandolin on this one (it’s an amazing tool isn’t it?)
    Plus, the flavor combinations are countless.
    Have you tried sprinkling with cheese at the browning stage? A little grated myzithra would be amazing with that (dry myzithra is a goat cheese used grated in pasta and potatoes here in Greece).
    Again, thank you for another AMAZING recipe Liz! Yummed!
    xoxoxo

  27. Looks fantastic! Can this dish be made ahead of time?

    • Hi, Beth, I think you could partially bake this and then pop it back in the oven for the final browning time. I haven’t tried this myself, but as long as you make sure the potatoes are tender, it should work! Let me know if you try these.

  28. hi liz i just discovered your blog and found some fabulous recipes. i have a question about
    your hasselback potato casserole. can i prepare it the night before – then let it come to room
    temperture the next day, and then bake according to your directions.

    • Pat, I would just worry about the potatoes oxidizing and turning brown. If you’re not serving to company, I think it could work! Let me know if you try them this way——it would be a great tip to add to the blog post.
