Crispy Roasted Mandoline Potatoes are perfect for family dinners or holiday meals. These oven-roasted thinly sliced potatoes are crispy and delicious.
Crispy sliced potatoes
These potatoes go by many different names, Hasselback potatoes, crispy sliced potatoes, mandoline potatoes or oven-roasted thinly sliced potatoes.
The potatoes are thinly sliced with a mandoline or a sharp knife. Then the whole potatoes are assembled in a dish. The rest of the ingredients are simple, just some olive oil and herbs.
Serve these for the holidays or for a dinner party. They are easy to make but always make a beautiful presentation.
Key ingredients
- Potatoes - I used red potatoes, but you could use your favorite potato or whatever potato you have on hand. Some options include Yukon gold, a white potato or even a small russet potato.
- Olive oil - Use a good quality olive oil.
- Herbs - Fresh rosemary and thyme
- Coarse Salt - Use kosher salt or other coarse salt rather than table salt. You want the salt to enhance the potatoes.
Making mandoline potatoes
How to make it
In this section, I share step-by-step photos, cooking methods, techniques, and a general overview. For detailed instructions, temperatures, and timing, check the printable recipe card below.
- Wash the potatoes.
- Slice thinly with a mandoline. You'll want approximately ⅛ inch slices.
- Lightly grease the casserole dish with olive oil.
- Place potatoes in the casserole dish. Try to keep the whole potato together and place the slices so the sliced ends face upwards.
- Brush tops with olive oil and bake in a 400°F oven for 40 minutes
- Remove from oven and brush tops with olive oil again and sprinkle with freshly chopped herbs. Return to oven and bake for an additional 30-45 minutes until potatoes are fully baked through and the top edges are slightly crispy.
- Remove from oven and top with additional fresh herbs and sprinkle with coarse salt.
- Serve hot in the casserole dish.
Recipe tips
- I left the potato peel on, but you can just as easily remove the peel.
- Plan on one potato per person. However, you do want your casserole dish filled with potatoes so add extra if needed.
- Try to cut your potatoes as evenly as possible.
Variations
- Parmesan Cheese - add shredded Parm to the top of the potatoes during the final 15 minutes of baking time.
- Change up the Herbs - use your favorite herbs. Add parsley or a bit of fresh marjoram instead of the rosemary and thyme.

These potatoes are wonderful and have become one of my favorite side dishes. Loved by all that have tried them. I've experimented with many different flavours. Depending on the main dish. Parmesan and garlic, cayanne pepper and turmeric, curry and cinnamon, yes cinnamon but very lttle. And the list goes on. Thank you!

Hi Kathy! These hasselback potatoes looks SO good. Yum. Those crispy edges. Thanks for the tips about to peel or not to peel, based on the potato type. I was unaware that red skins are thinner! Good to know. Thanks for another great post!
Kathy says
I like the taste of the skin too, plus it has lots of nutrients in the skin!

I love haselback potatoes and your beautiful pictures put me in the mood to make them again. I like the fact that you don't use so much fat, I've seen recipes using half a pound of butter or so.
Kathy says
I do love butter, but these just don't need it!

David @ Spiced says
These potatoes look like the perfect side dish for the holidays, Kathy! I love hasselback potatoes with the combination of soft and crispy! I seriously could make an entire meal out of just these potatoes. In fact, I might just have to do that soon...these look SO good! 🙂
