The most delicious vegan scalloped potatoes. These are the perfect side dish for any occasion- they’re super easy to make and will totally wow your guests!
I hereby present…vegan scalloped potatoes.
And I present it very formally because I have to make a fuss somehow. Getting this recipe right was kind of a struggle. Just a small struggle.
We made it approximately 12 times. It might’ve even been more. We ate so much scalloped potatoes we pretty much overdosed on them.
But I have to say, when we got it right, it was so darn perfect that it made it all worthwhile.
I mean, it’s the perfect side dish for a special occasion or holiday dinner.
And now I’m very confident that this recipe is spot on and fail proof!
How To Make Vegan Scalloped Potatoes
Full instructions and measurements are in the recipe card at the bottom of the post, this is just a summary to go along with the process photos.
- Add coconut milk, raw cashews, ground black pepper, dijon mustard, nutritional yeast, sea salt, onion powder and garlic powder to the blender jug and blend.
- Peel and thinly slice potatoes and onions. Layer half of the potatoes in a 9×13 oven safe dish and then add all the onion in a layer on top of the potatoes.
- Pour over half the sauce.
- Then add the remaining half of the potatoes.
- Pour over the remaining sauce.
- Cover with foil and bake in the oven at 350°F for 75 minutes. Remove the foil and then return to the oven for a final 40 minutes.
- Allow to cool for 10 minutes and then sprinkle with chopped chives.
Recipe Tips
Slice the potatoes (and onion) evenly and thinly. This helps them to cook evenly, and a little faster, though, let me not lie, this is not a ‘fast’ recipe, it bakes for a looong time.
You can either use a mandolin slicer to slice your potatoes very evenly or you can slice them by hand. I definitely can’t do perfectly even, thin slices by hand but Jaye can, so I bring him in on important jobs like this.
Blend the sauce very well so that it is completely smooth. It’s a very simple sauce, but you want it to be smooth and completely blended so there is no graininess to it.
Bake it long and slow. The magic formula for this recipe is baking it at 350°F covered with foil for 75 minutes and then removing the foil and baking it for another 40 minutes uncovered.
Recipe Q&A
Either russet or yukon gold potatoes are going to be great for this if you’re in the USA. If you’re elsewhere in the world, any nice starchy potato that is great for baking is going to work well for this.
No, I don’t think it does. It has more of a ‘cheesy’ creamy type of flavor and texture. I do recommend you use full fat unsweetened coconut milk from the can, as that is what is going to produce the best results for this recipe.
Make Ahead and Storing
Make ahead: You can definitely make this in advance. The best way to do it is to hold back about ½ cup of sauce.
Bake covered in foil for the 75 minutes as usual, but then remove from the oven and leave the foil on while it cools.
When it’s cooled, remove the foil and add the remaining ½ cup of sauce, spreading it evenly.
Cover with foil again and place into the fridge. When you’re ready, preheat the oven, and reheat it with the foil on for 20 minutes (just to get to the same point we would be in if we never chilled it), and then remove the foil and bake it for the 40 minutes uncovered (as per the recipe).
Storing: Leftovers keep very well covered in the fridge and will stay good for 3-4 days.

Notes
- Spray your baking dish with non-stick spray if you think there is any chance of it sticking. The dish I use never sticks so I didn’t use it, but you may need to.
- Leftovers keep very well covered in the fridge for 3-4 days.

This looks really good, but is the time on this correct? An hour and 15 minutes followed by another 40 minutes at 350 degrees seems like it would burn. Did everyone who made this follow the time guidelines? Thanks
It’s definitely correct! Potatoes take a while to cook through.
Thank you for replying to the email about the time because I was thinking the same thing. It’s in the oven now. 😊
I have made this countless times and it is always a hit. Freeze the rest and reheat with no issues at all! Thank you for a wonderful recipe.
Fantastic! Thanks so much Joanne!
I’ve baked this twice now and each time, it’s a treat to have for a meal with just a salad! Creamy and delectable.
Wonderful! Thanks Anna!
I loved everything but the coconut flavor. Next time I’ll try using oat milk.
This seems like a great recipe for a slow cooker on low all night! Have you tried that? Also, it would be great to have the weight measure for the onion. It looks like a large onion to me but I could be wrong! Thanks!
Hi Alicia, I don’t have a slow cooker so I’ve never tried that. I also don’t tend to weigh onion, but you need enough to form a full layer. So a medium to large onion is about right. Not one of those massive ones though! 🙂
I was wondering if we could substitute the coconut milk with either oat milk or almond milk?
Yes I think that will work fine!
Turned out amazzzing and tasted great, it was an instant hit.
Wonderful! Thanks so much Rubina!
I made this two days ago and it disappeared. I just took the second pan out of the oven. I used all the potatoes that needed to be used. So we have a 3 quarts Dutch oven full. This is really good. I’m glad I saw your recipe on Pinterest
So glad you enjoyed it Nancy! Thanks for the great review!
