Move over, mashed potatoes, Vegan Scalloped Potatoes are a perfect side dish for holiday feasts!
Scalloped Potatoes were a Childhood Favorite
It may sound kind of weird, but I didn’t like potatoes very much growing up. Of course, I love French fries, but I didn’t care much for baked potatoes, and mashed potatoes seemed too much like paste for me. I did, however LOVE scalloped potatoes. I loved the combination of creamy sauce with thinly sliced potatoes, and I especially loved the crispy bits at the top of the dish.
My made scalloped potatoes often, but she never made them from scratch. They always came from a boxed kit, which in retrospect is kind of gross, but hey, it was the 70s. I love veganizing my childhood favorites, and since potatoes are a Thanksgiving favorite, it’s about time I created a vegan scalloped potatoes recipe.
Vegan Scalloped Potatoes are perfect for the Holidays
This is the type of recipe that I usually make with cashew cream, however, my Thanksgiving menu is already a little too cashew-based, with Green Bean Casserole, Creamed Kale, and Pumpkin Swirl Cheesecake planned. I chose to use cauliflower to make a cream sauce for these vegan scalloped potatoes, and it took a few tries, but I think I finally got it right. Dennis was happy to eat the results of my experimenting, so nothing went to waste.
Slicing the potatoes can be a little tricky. If you have a mandolin, it’s a great way to get thin slices. I got rid of my mandolin while on a big decluttering binge over the summer, but my food processor has a slicing blade, so I used that, and it worked beautifully. If you don’t have either, use a sharp knife and try to get your slices as evenly cut as possible.
These vegan scalloped potatoes are a terrific side dish option for Thanksgiving or Christmas dinner. They’re great for Sunday supper, too!

Bring the water to a boil over medium-high heat and then reduce the heat and allow to simmer for about 15 minutes or until the vegetables are fork tender.

This looks amazing! Brad always had scalloped potatoes on Christmas growing up, so I will definitely need to make this for him. And using cauliflower is genius!
Thank you, Amy! I hope he likes it!
That looks lovely Dianne, I definitely want to try that one! It reminds me of Dauphin Gratinois…but much healthier. I am a follower of yours from Wales (U.K.) so will need to find an equivalent to Yukon Gold potatoes, are they large yellow fleshed baking types please? Thanks again for the recipe… 🙂
Thank you, Elfed! Any type of potato that you would roast or bake would work well in the recipe. I hope you enjoy it!
Ah that’s fine – thank you ! Just to add the interest in Veganism in all its form in Britain is growing exponentially…long may it continue either side of “the pond” ! 🙂
That’s great news!
Oh my gosh, these look so perfect! Who says mashed potatoes deserve all the glory?
Thank you, Becky!
