Vegan Purple Sweet Potato Pie

Vegan Purple Sweet Potato Pie is a colorful twist on the classic sweet potato pie. This plant-based pie is gluten-free and dairy-free, yet still rich and decadent. A delicious vegan Thanksgiving dessert.

Vegan Purple Sweet Potato Pie

I love purple. I mean, I made the color of this blog purple. My childhood bedroom is purple. I'm obsessed with purple cauliflower. And purple sweet potatoes are my favorite!

So, naturally, when I was brainstorming Thanksgiving desserts, I immediately gravitated towards something purple.

And, I mean, who else is tired of pumpkin pie every Thanksgiving? (Unless it's pumpkin spice latte pie, of course!)

Purple Sweet Potato Pie is like the fun cousin of regular sweet potato pie. Purple sweet potatoes are more dense than regular orange sweet potatoes, so this pie ends up being rich and thick and decadent.

It's also incredibly beautiful to look at.

Why I love this Vegan Purple Sweet Potato Pie

  • Dietary needs — this pie is completely plant-based, oil-free, gluten-free, and refined sugar-free. It's made from whole foods, for a dessert you can feel good about eating.
  • Perfect holiday dessert — sweet potato pie is a classic Thanksgiving dessert, and you spice it up by using purple sweet potatoes instead of the traditional orange-fleshed potatoes
  • Make ahead — this pie is a great dish to prep ahead of time. You'll want to serve the pie cold anyways, so it's easy to make a day or two before Thanksgiving and save oven time for other dishes
  • It's purple — I know, I already mentioned this. But seriously, this pie is so beautiful.

Ingredient Notes & Substitutions

Crust Ingredients

While the crust isn't the star of the show, we still want to bake a tasty crust that is strong and will hold in a dense sweet potato filling.

  • Oat Flour: Oat flour makes a great pie crust, it has a neutral flavor, but is strong and not crumbly. While I usually use homemade oat flour in my recipes, for pie crust I recommend using store-bought oat flour because the consistency is more fine
  • Pecans: Pecans add nuttiness and a bit of fat that makes the crust rich and flavorful. You can also use another nut like almonds.
  • Maple or Date Syrup: I find that adding sweetness to a vegan pie crust really creates flavor. You can use either maple syrup or date syrup, depending on your preferences. Date syrup will create a darker crust and make this pie completely fruit-sweetened. Maple syrup is sweeter than date syrup and will create a lighter colored crust.
  • Salt
  • Water: A bit of extra moisture brings the crust together and makes it workable.

Filling Ingredients

  • Purple Sweet Potatoes: you can find purple sweet potatoes at Whole Foods or other health food stores.
  • Flax Egg: A blend of flax and water, a flax egg replaces a 'real' egg and helps bind the pie together.
  • Maple or Date Syrup: Either syrup will work. Again, maple syrup is sweeter than date syrup, but date syrup will make this entire pie fruit-sweetened.
  • Nut Butter: a nut butter like cashew butter or almond butter adds a source of fat in this pie, which creates a deeper flavor
  • Applesauce: Applesauce adds extra sweetness and helps lighten up the texture of the pie. Be sure to buy unsweetened applesauce to avoid refined sugars
  • Spices: cinnamon & nutmeg
  • Vanilla Extract
  • Salt

Expert Tips & FAQ

What are purple sweet potatoes?

Purple sweet potatoes are a type of sweet potato with a purple flesh and skin. Some sweet potatoes (like Japanese sweet potatoes) have a purple skin with white flesh. But purple sweet potatoes have that gorgeous purple flesh.

There are a few varieties of purple sweet potato. The most common is Stokes. These potatoes are mildly sweet and moist, with a vibrant purple interior and are ideal for using in pies.

Choose the right pie dish.

Pie pan sizes are so confusing. There are a lot of different shapes and sizes. This pie works in an 9" deep dish pie pan.

To see if your pie plate will work, measure across the top from edge to edge. Then measure the height by placing your ruler on the outside of the dish. A standard pie dish will be 1" to 1.5" deep, whereas a deep dish is closer to 2" deep.

The pie dish I used for this recipe is considered a deep dish when you bring the crust all the way up the sides. I like this pie dish because if you want a regular-depth pie, like this recipe, you can use the same dish and only bring the crust up to the lower rim.

Make ahead of time.

This recipe is great to make a day or two before you'd like to serve it. The entire pie can be baked and refrigerated until you're ready to serve.


Store this Purple Sweet Potato Pie in the fridge for up to a week.

You can also freeze this pie if you have leftovers. Remove the pie from the dish and wrap tightly in plastic wrap before placing in another container.

I was in the middle of making your Tempeh Swiss Chard recipe and noticed you never mentioned how much Swiss Chard to add. I just added the sautéed tempeh towards the end and mixed it all together. I also reduced the amount of red pepper flakes.
Hi Jenny - so sorry about that! It should be one bunch. I've updated the recipe to include the correct information. Thanks!

This looks fantastic! Do you think we could substitute butternut squash for the acorn squash?
Hi Elissa - you can definitely use butternut squash. In terms of texture, the pie will be exactly the same with either squash. I'd recommend using the volume measurement instead of the weight measurement, since the density of butternut squash isn't exactly the same as acorn squash. Also, the flavor of the butternut squash might come through in the end pie a bit more prominently than acorn squash does, but I don't think it will be too noticeable. Let me know how it goes if you try with the butternut squash. I'd love to hear!

Hi Katherine - yes, I did use fire-roasted tomatoes when I photographed this recipe. I don't call for fire roasted in the recipe because it's intended to be a basic, use-in-anything type recipe. But it does taste delicious with the fire roasted tomatoes! -- Elizabeth

It's close to my bedtime, but I've been thinking about making this recipe all day, so I made it just now. After all, it only takes 15 minutes! I used what I had, so I made a few minor substitutions...white beans for cannellini, purple basil from my garden, red onion for more color, and date syrup for maple. I took a bite before putting it in the fridge for tomorrow, and oh my! It's delightfully flavorful, light, and fresh-tasting. Thanks for sharing your recipe!
Hi Linda - I'm so glad you liked the recipe - and your substitutions sound great (wish I was growing purple basil in my garden!) Thanks so much for sharing!

Hi, is this ice cream soft to scoop out? I always find my ice creams are hard.
Hi Carol - yes, this ice cream is soft if you let it thaw a few minutes after you take it out from the freezer. It can become pretty solid if it's in a deep freezer, but still thaws quickly on the counter. Hope this helps!

Hi Elizabeth! I found you by searching for plant based Catholics! There are very few of us! Thank you for your site and sharing recipes!! I look forward to trying these muffins! Can sugar be reduced safely in most of your recipes? -JMJ-
Hi Katherine, Thanks so much for reaching out! Glad to meet another plant-based Catholic - agree, there are so few of us. As for sugar, I never use white granulated sugar in any of my recipes. Most use maple syrup or date sugar/date syrup. I'm not sure if this is what you mean, or if you're asking about reducing the amount of date sugar that the recipe calls for. If that's the case, it really depends on the recipe. A lot of the baking recipes have specific ratios of flour to sugar and wet to dry, so it may not go well if you change the amount of sugar. I hope this helps, but if I didn't answer your question, please let me know. Also happy to advise on a particular recipe if you're looking to change it. Let me know how I can help :) Elizabeth

Love this vegan lentil/mushroom stew! For some odd reason, I had never thought to put mushrooms into my lentil stew. Thank you for a wonderful addition to my recipe box!

Hello, I found you on FB and really enjoy your Catholic Plant Based GF information & recipes. About the Chickpea beet burgers: if the beans are dried and not cooked, do you think it is enough cooking for the beans? If beans are not cooked completely I have read they are toxic with phytic acid & also cause digestive problems. I am just wondering and will leave it to you to decide/research. To be safe I am toasting canned garbanzos and trying that way out. God Bless
Hi Geraldine, Thanks so much for reaching out. In the beet burgers, the beans do get cooked when the burgers are cooked. You soak them first and then incorporate the beans into the burger patty, then cook the patty. I find that this is the best way to achieve the proper burger texture - if you use pre-cooked beans or canned beans the burgers are mushy and don't get crisp. Your solution of toasting the beans sounds like a great idea to completely ensure the beans are cooked fully - I hope that it worked for you and your burgers turned out well! -- Elizabeth

Can you leave nutritional info for your recipes? Serving size/calories would be so helpful! Trying mushroom lentil stew tonight! and looking forward to crispy chickpea stuffed sweet potatoes very soon. Thanks for creating healthy, attractive recipes!
Hi Katie - so excited to hear that you are trying some of my recipes! I'd love to hear how they go. I haven't posted nutritional information for my recipes because I know it can be difficult for some people with disordered eating to see nutrition facts. I've gotten a lot of requests to add them recently, so I'm working on a solution that can provide information for those who want it but not be triggering for others. In the meantime, if you're curious about the nutrient info about a particular recipe, I recommend using Cronometer. It's a website/app to track and understand nutrient info and I think it does a great job of emphasizing all the nutrients (not just macros). I hope this helps! Please let me know if I can help in any other way.

U mentioned date sugar on this recipe but it’s not in the instructions. I know u add it but just in case u wanna add to instructions. Love ur recipes! Thank u. I’m thinking of going to vegan a little nervous tho lol

I'd love to try this soup. What are the nutritional values, like how much fat does it contain, carbs, etc.
Hi Sr Maureen - I usually don't post macronutrient information because I know each person has their own goals and I don't want to encourage or discourage anyone's specific goals. But I often use Cronometer as a tool to understand the nutritional profile of my recipes. I plugged the ingredient information for this recipe into Cronometer and got the following nutrient information per serving: 521 calories, 44g fat, 23g carbs, 16g protein. I hope this helps. Please let me know if you have any other questions and if you try the recipe!

Thank you I have been doing the fruit and oatmeal, etc for years and I love it. I will try the pears. I refrigerate my left over oatmeal and with a touch of milk or fruit juice liquid it’s fine the next day. Just a warning about tofu; it interferes with some medicines especially Thyroid medicine. Thank you for the short prayers, there are lovely.
Hi Martha - thank you so much for your kind words. I'm glad you like the prayers! As someone who doesn't take any medications I have no issues with eating tofu and encouraging others to eat it too (it's a great source of protein!). That said, you should always consult with your doctor about possible interactions with medications. I have plenty of recipes without tofu, so hopefully you can find things that work for you!

When you say shape into a rectangular loaf, what dimensions? 1/2 thick by 8 inches long or?
My loaf was about 7" long and 4" wide with about 1" of height. Then I sliced it 1/2" thick along the long end to get 12ish biscotti. I will clarify this in the post! Let me know if this makes sense and if you have any other questions.

Hi Could you please confirm two things:1. The amount of salt. Seems like too much. 2. The directions say there is lemon juice in the dressing but it’s not listed under ingredients. ThanksL.
Hi there! Confirming that the two teaspoons of salt in the dressing is correct. I didn't salt the cauliflower when roasting it or the salad after it was done, so this amount of salt was perfect. If you're concerned about it you can decrease the amount of salt in the dressing and then add more at the end if you need it. As for the lemon juice, SO sorry about that! It was a typo in my directions and I've removed it now. Hope this helps :)

Hi Martha! I don't have a recipe for red pepper hummus on my site. I suggest taking a traditional hummus recipe and blending in roasted red pepper.

Hi, these look amazing. I was wondering, could I used powdered peanut butter in place of creamy for the recipe? thanks
Hi Grace! There is already some powdered peanut butter in this recipe, so adding more might make the texture more gluey. Also, the real peanut butter adds some fat, which helps create flavor. That said, if you want to use powdered peanut butter, I would suggest mixing it with a high-fat liquid like coconut cream and then measuring out 2/3 cup. Hope this helps! Let me know how it goes :) -- Elizabeth
November 15, 2021
You mention using vegetable broth in your introduction but it isn’t included in the recipe
Hi Becky - thanks for pointing this out. I have removed mention of vegetable broth from this post. You do not need any vegetable broth. The mushrooms will release natural liquid which will prevent any sticking. -- Elizabeth
