Saweet! Potato Casserole with a Crunchy Nut Crumble (Vegan + GF)



This is a side dish you’re going to want on the holiday dinner table. Or maybe, on your regular fall dinner table. Because who can wait for the holidays? It is sweet potato season after all, which means in this house we’re cooking them a couple times a week. Give me all the sweet potatoes, please. They are the edible equivalent to a big warm hug.

Now that it’s officially November (plus chilly and dark at 6pm…tear…sob), I figure some of us are thinking about happier things…like the holidays and all the delightful holiday food. I know I am. It’s my favourite time of the year to cook and bake. For some reason, I always have oodles and oodles of recipe ideas floating through my mind this time of the year and can’t keep up with testing them all out. You should see my “to make” list…it’s massive!

In preparation for the holidays, I decided to do something I’ve been meaning to do for a long time; I revamped my old sweet potato casserole recipe from 2009. It’s a good recipe, but with 5 years of recipe development under my belt I knew I could improve upon it. This version got lightened up and given a crazy good pecan oat maple crumble topping. It totally blew us away and the previous recipe is all but history in my mind.

Just look at this crunchy crumble…


Here are a few things I changed up:

1) cut sweetener by over half (you won’t even notice)

2) added some heart-healthy virgin coconut oil

3) added a new and improved crunchy topping – gives it a great texture contrast!

4) made this one gluten-free as the old one wasn’t

5) amped up the maple + cinnamon flavours

6) new photos…because 2009 wasn’t my best year for photography…hehe

I recommend serving each portion with a pat of vegan butter or coconut oil on top to really take it over the edge. The butter/oil melts and cascades all over the casserole. Bliss!!

I love you, sweet potatoes.

Sweet Potato Crumble Casserole

Vegan, gluten-free, refined sugar-free, soy-free


This is a side dish you're going to want on the holiday dinner table! The crunchy nut crumble tastes just like an oatmeal cookie. I recommend serving this casserole with a pat of vegan butter or coconut oil to really take it over the top. Also try serving it with Coconut Whipped Cream for a decadent twist. In this recipe, I swapped out half the vegan butter for virgin coconut oil to add some heart-healthy fats while still retaining that lovely butter flavour.

8 servings
Prep Time
Cook time


For the sweet potato mash:
  • 4 1/2 to 5 pounds sweet potatoes (about 4 to 5 large)
  • 1 1/2 tablespoons vegan butter
  • 1 1/2 tablespoons virgin coconut oil
  • 2 1/2 tablespoons pure maple syrup, or to taste
  • 1 teaspoon pure vanilla extract
  • 3/4 teaspoon cinnamon
  • 1/8 teaspoon ground nutmeg
  • 1/2 teaspoon fine grain salt, or to taste
For the Crunchy Nut Crumble:
  • 1 cup rolled oats (use certified gluten-free if necessary)
  • 1 1/3 cups pecan halves, chopped
  • 1/3 cup almond meal or almond flour
  • 1 teaspoon cinnamon
  • 1/4 teaspoon fine grain sea salt
  • 2 tablespoons virgin coconut oil, melted
  • 2 tablespoons vegan butter, melted
  • 2 1/2 tablespoons pure maple syrup


  1. Peel and roughly chop sweet potatoes into large chunks. Place into a large pot and cover with water. Bring water to a boil, reduce heat to medium-high, and gently boil for 10 to 20 minutes, until the potatoes are fork tender. Drain.
  2. Preheat oven to 375°F. Lightly grease a 2 1/2-quart (10-cup) casserole dish and set aside.
  3. Prepare the crumble topping: Pulse the oats in a food processor until coarsely chopped. In a medium bowl, stir together the chopped pecans, oats, almond meal/flour, cinnamon, and salt. Pour on melted coconut oil, melted butter, and maple syrup. Stir until combined.
  4. Once cooked and drained, place sweet potatoes into a large bowl.
  5. Mash potatoes with the butter and coconut oil until smooth. Now, stir in the maple syrup, vanilla, cinnamon, nutmeg, and salt. Adjust to taste if desired. Spoon into casserole dish and smooth out.
  6. Sprinkle the crumble topping all over the sweet potato mixture, evenly.
  7. Bake, uncovered, at 375°F for 16 to 23 minutes, until the dish is hot throughout. Plate and serve immediately with a pat of vegan butter or coconut oil.


  • For a creamy twist, try subbing some of the butter/oil in the sweet potato mash for full-fat canned coconut cream.

Can you cook this in a slow cooker?

This is the third Thanksgiving in a row that I am making this for my husband’s family! It’s such a crowd pleaser for ALL the palates (including my brother-in-law, who doesn’t like sweet potatoes, but loves this dish!). The whole family also likes the Double Chocolate Coconut Torte, but I was too lazy to make that one too this year :) Thanks for your awesome recipes!

One note to make this recipe even easier: roast the sweet potatoes in the oven a day ahead. If you roast them a bit extra, the skin will come right off when they’re cool, and it’s way easier! They’re also easier to mash this way.


Angela Liddon November 24, 2016

Hi Kristen, Thanks so much for the lovely comment! And for sharing the great tip, as well. :) I hope you have a wonderful Thanksgiving with the family!


Erin Serrault November 22, 2016

I really love this recipe! I’m trying to remember though that I thought you offered a variation on the crust topping. Was there one with walnuts? and possibly brown sugar with oats.


Emily November 17, 2016

This looks amazing and I am definitely planning on making this for Thanksgiving! I have family with nut allergies, would the recipe work with vegan marshmallows on top?


Angela Liddon December 14, 2016

Hi Emily, sincere apologies for not getting back to you sooner! Did you end up trying it with the marshmallows? I’d love to hear how it went. :) (I expect the results would be pretty delish!)


Jenna November 13, 2016

Love this recipe and have made it for the last few years at Thanksgiving! This year I need to make accommodations for a friend with a coconut allergy. Is there another vegan option?

I just made this using walnuts (ran out of pecans..) and it was sooo good. Thank you for a wonderful recipe! :)


Angela Liddon November 14, 2016

Glad you enjoyed it Anya!

Thanks for the options Angela!
Loved the recipe and it came out great. I used my kitchenaid to whip the potatoes and mix everything in. Loved the crumble topping, it would be perfect on a fruit dessert as well.
Pretty easy to throw together, too


Angela Liddon October 11, 2016

Yay! Glad it was a hit. :)

Any options if no vegan butter is available? (small town, no stores that carry it!)


Angela Liddon October 7, 2016

Hi Zahra, I’d say you could replace the vegan butter with more coconut oil. Or for the mash, simply omit the butter altogether (especially if you don’t want the coconut flavour to be too strong). Another option is to try full-fat coconut cream, or if you aren’t a fan of the coconut flavour, try refined coconut oil which is flavourless. Hope this helps!


Elizabeth Sauve March 27, 2016

I made this! My tip? Increase the maple syrup and add coconut whipped topping, its a dessert. For a side dish, decrease the syrup by half and its perfect.

I also omited the margarine…still delish! Great recipe all round.

I’ve made this the past two Thanksgivings… since it’s been up on the blog. It is a wonderful crowd pleaser and your non-vegan family members will love it. Not too sweet, and you use real sweet potatoes (none of that canned stuff). The lovely crust it makes on the top is to die for.


Laura December 23, 2015

Hi, can you use oat, plain, rice or tapioca flour instead of almond flour? Also, does it work OK with macadamia or almonds instead of pecans?


Elliott December 22, 2015

Sounds great! I’m going to try this for Christmas. I don’t usually keep almond flour at home; could I substitute regular all purpose flour, or something else?

I made this yesterday to ‘test’ for my Christmas Eve menu. It is wonderful! The smoothness of the sweet potato with the crunchiness of the topping is just fabulous. This will certainly be on the Christmas Eve menu. Thank you!

Holy cow these are AWESOME! It’s not the point when cooking *healthy*, but my boyfriend and I ate the whole batch in, um, maybe one day and really didn’t feel that bad about it ;)

I didn’t have the *butter* and just used extra coconut oil in place and it was still just divine. I’ve already shared it three times and will be including it in some of my social media shares.
