How to Make Vegan Skillet Sweet Potato Casserole

This skillet casserole recipe is made with fluffy and creamy mashed sweet potatoes with a sweet and crunchy topping. Start by making the mashed sweet potatoes, then make the nutty pecan topping. Put everything together into one skillet, bake, and enjoy a dairy-free and healthy side dish!


Here's what you need to assemble this vegan casserole for the holidays: 

  • Mashed sweet potatoes: Cooked until smooth, either in the oven or on the stove. (Check the notes section for oven-roasted mashed sweet potato instructions.)
  • Canned coconut cream: Alternatively, you can use canned full-fat coconut milk.
  • Vegan butter: I love the brand Earth Balance.
  • Brown sugar: Make sure it's organic for a vegan-friendly option.
  • Maple syrup: Opt for pure syrup, not imitation or pancake syrup.
  • Vanilla extract: Use pure vanilla, not imitation.
  • Vegan marshmallows: Ensure they're free from animal gelatin.
  • Raisins: You can also substitute with dried cranberries, cherries, or golden raisins.
  • Warming spices: The recommended spices include cinnamon, nutmeg, and allspice.

Nutty Casserole Topping

After you make the creamy, smooth sweet potato filling, whip up the nutty and crunchy topping. Here's what you need:

  • Pecans. Use toasted nuts for the boldest flavor. 
  • Flour. Use organic flour to make sure it's vegan. 
  • Brown sugar. You can use dark or light brown sugar. 
  • Vegan butter
  • Cinnamon

Tip: Pecans can burn easily, so keep a close eye on the casserole in the oven. Once you start to see color, they'll keep cooking, so don't be afraid to remove the pan from the oven early.

How Many Sweet Potatoes for This Casserole? Larger Batches?

When it comes to this Vegan Sweet Potato Casserole, I used two large sweet potatoes which fit nicely in a standard 9x13 baking dish and serves about 8. However, you can definitely make a larger batch by doubling or even tripling the ingredients (including the amount of sweet potatoes) if you're entertaining a larger crowd! You might need to use a casserole dish instead of a skillet in that case!

Health Benefits of Sweet Potatoes

Starting your day with a serving of sweet potatoes is more than just delicious. These root veggies are also great for your health. Some important health benefits of sweet potatoes include:

  • Improved digestion. They actually contain more fiber than regular potatoes! Sweet potatoes are also a great source of magnesium, which helps aid digestion.
  • Boost Your Immune System. Sweet potatoes are rich in beta-carotene (a major antioxidant). This fuels your immune system to help protect your body against illness and foreign invaders. You'll also find plenty of vitamin C and B-complex, iron, and phosphorus in these tubers.
  • Treat Stomach Ulcers. Sweet Potatoes can help soothe and repair the stomach and intestines. The immune-boosting vitamins also help cure stomach ulcers. In addition, the dietary fiber helps prevent constipation and acid formation. This can reduce the risk of ulcers.
  • Other Benefits: Sweet potatoes are also naturally anti-inflammatory and can reduce arthritis, pain.

When to Add Marshmallows to Sweet Potato Casserole

Knowing when to add the marshmallows to your sweet potato casserole is super important, especially when you're trying to avoid holes within your casserole from the marshmallows cooking too much and basically "disappearing". Yes, that does happen and has happened to me a few times. Haha.

However, I've learned that you can combat this in two ways: Bake your casserole covered with foil for the first half of the time and then remove it for the remaining time OR you can add half of the marshmallows initially and then in the last 10 minutes or so, tuck the remaining ones in the casserole so that it melted just enough to still be in tact.

Topping + Ingredient Suggestions for This Sweet Potato Casserole

I like to add a bit of crunchiness to the top of my sweet potato casserole, which is why I chose to use this simple pecan option as well as the straight-forward filling ingredients. But I wanted to share a few more ideas incase you make this casserole more than once and want to switch things up!

Other topping + ingredient ideas include:

  • Candied bacon (You can add this to a crumble topping)
  • Traditional pecan crumble topping
  • Additional nuts (i.e. walnuts, hazelnuts, etc.)
  • Bourbon (For a nice adult kick)
  • Orange zest to brighten up the flavors.
  • Toasted coconut flakes for a tropical twist.
  • Pineapple chunks
  • Dried cranberries

Serving Suggestions

This timeless classic is an ideal choice to grace your Thanksgiving or holiday table. It's a vegan side dish that truly shines when served with:

Vegan Skillet Sweet Potato Casserole Q + A's

How Long Can Sweet Potato Casserole Sit Out?

According to research, it's recommended that you don't leave cooked sweet potatoes out for more than 2 hours as this can promote bacterial growth. Therefore, if you aren't serving your casserole right away, be sure to let it cool and then refrigerate it until ready. You can easily reheat it in the oven when serving for that nice warm scoop.

Can I Make Ahead Vegan Sweet Potato Casserole?

Absolutely! You can prep and roast the sweet potatoes in advance, let cool completely, and store in an airtight container and refrigerated until the day of. Let it sit at room temp. for a few minutes and assemble per the recipe.

How to Store + Reheat Southern Maple Sweet Potato Casserole

Leftovers can be stored in a tightly sealed container in the refrigerator for up to 4 days, for optimal freshness. To reheat, simply add the casserole to the preheated oven at 375 degrees Fahrenheit and let it warm through. Again, you may need to add additional marshmallows if desired.

Can I Make This Vegan Casserole Gluten-free?

Yes! Simply replace the flour in the delicious crumble topping with gluten-free flour. I love Bob's Red Mill GF Flour.

Get ready to savor this Vegan Skillet Sweet Potato Casserole – A wholesome masterpiece featuring fluffy mashed sweet potatoes naturally sweetened to perfection, and crowned with a delectable buttery pecan crumble topping. It's a dish that deserves a spot on your Thanksgiving table or any occasion really! Gluten-free option.
Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour
Serves: 8 servings



  • 4 cups mashed sweet potatoes (See Notes)
  • ½ cup canned coconut cream (You can also use canned coconut milk)
  • ½ cup vegan butter
  • ¾ cup organic brown sugar
  • ¼ cup pure maple syrup
  • 1 teaspoon vanilla extract
  • 1-2 cups vegan marshmallows
  • ½ cup raisins
  • 1 tablespoon ground cinnamon
  • 1 teaspoon ground nutmeg
  • ¼ teaspoon ground allspice
  • 1 teaspoon sea salt


  • 1 cup pecans, roughly chopped + toasted
  • ½ cup organic all-purpose flour
  • ½ cup organic brown sugar
  • ¼ cup vegan butter, partially melted  (See Notes!)
  • 1 teaspoon ground cinnamon
  • pinch of sea salt



  • Preheat the oven to 375 degrees Fahrenheit and grease a medium oven-safe cast iron skillet with vegan butter.
  • In a bowl, add all casserole ingredients, mixing everything together until combined.
  • Scoop the mixture into prepared skillet, evenly spreading everything out. For a little extra goodness-----tuck in a few additional marshmallows into the mashed sweet potatoes, pressing them gently all around.
  • Make the topping.


  • Add the flour, brown sugar, chopped pecans and cinnamon, into a medium bowl, combining them together using a pastry blender. NOTE: This helps to breakdown the nuts into smaller pieces as well, if preferred.
  • Add the partially melted vegan butter and using a spatula, mix until well combined and 'crumbly-like'.
  • Now, evenly sprinkle the crumble topping atop the casserole or until fully covered and place it in the oven.
  • Bake the casserole for 30-40 minutes or until the top is golden brown and the marshmallows have melted in the centers. Remove from oven and serve.
  • Bon Appetit!

Tips & Tricks

  • STORAGE: Leftovers can be stored in a tightly sealed container in the refrigerator for up to 4 days, for optimal freshness. 
  • SWEET POTATOES: Preheat oven to 425 degrees Fahrenheit and line a baking sheet with parchment paper or foil. Rinse sweet potatoes (about 2 large ones) and pat dry. Lightly coat potato with Extra Virgin Olive Oil and place in oven, baking for 45 minutes to 1 hour, until tender and juices begin to bubble outside of skin. Remove from oven, let cool for 10-15 minutes and slice in half. Remove sweet potato insides and place in a bowl, mashing it until “pureed”. Continue recipe.
  • TOASTED PECANS: Add chopped pecans to a baking sheet and toasting them in the oven (400 degrees Fahrenheit) for 5-10 minutes, tossing them halfway to avoid browning on one side.
  • SWEETENER: If you choose to opt out of pure maple syrup, you can always substitute with Agave as well.
