Growing up, I was always a fan of sweet potato casserole. After all, between the mashed candied yams and the marshmallow topping, it was really just dessert! Then, one year, my aunt brought over a new version of sweet potato casserole. Instead of marshmallows, she’d topped it with a crunchy pecan crumble. It was a game-changer. From then on, sweet potatoes became one of the stars of the Thanksgiving show and we always opted for the pecan version.

My ideal menu would be: a perfect oven roasted turkey, traditional turkey gravy, creamy mashed potatoes, homemade gluten-free stuffing, this yummy sweet potato casserole, balsamic roasted Brussels sprouts, and gluten-free pumpkin pie.

Recipe Ingredients

There are thousands of sweet potato casserole recipes on the internet, but this one stands out thanks to the pecan topping, the fluffy mashed sweet potatoes sweetened with pure maple syrup, and the hint of orange in every bite. Find ingredient notes (including substitutions and swaps) below.

Ingredients for sweet potato casserole sit in a variety of bowls. Cubed sweet potato lays on a brown chopping block.
  • Heavy cream or milk – for a truly indulgent casserole (there’s no better time for it than Thanksgiving, after all), we recommend using heavy cream in this recipe. If you’d like to lighten the dish up, though, you can replace the heavy cream with regular milk.
  • Pure Maple Syrup – be sure to buy pure maple syrup! Really good maple syrup makes all the difference.
  • Flour – for the pecan topping, you can use regular all-purpose flour or this gluten-free all-purpose flour for a gluten-free version.
  • Brown sugar or coconut sugar – the topping works with both brown sugar or coconut sugar if you’re looking to make a refined sugar-free version!

A full ingredient list with exact amounts can be found in the recipe card below.

Recipe Variations and Modifications

  • Make it dairy-free – use full-fat coconut milk in place of the cream and substitute ghee or your favorite vegan butter for the butter.
  • Make a paleo crumble – for a Paleo crumble, use the crumble in this paleo apple crisp.

How to Make Sweet Potato Casserole

Here’s how you’ll make this easy sweet potato casserole recipe:

A piece of softened sweet potato is held with a fork over an orange, enameled pot of more softened, cubed sweet potato.
A brown, chunky mixture sits in a white bowl. A green spatula sits to the side along with a variety of other ingredients in individual bowls.

Step 1: Preheat the oven to 350°F. Place the cubed sweet potatoes and 2 teaspoons of salt in a pot and cover with one inch of water. Then, bring the water to a boil over medium-high heat. Cook for 20 minutes, until the potatoes are easily pierced with a fork, then drain out the water.

Step 2: While the potatoes are boiling, make the crumble. Whisk together the flour, sugar, and cinnamon, then stir in the butter until a crumbly mixture has formed. Stir in the pecans and set aside.

Step 3: Use a potato masher to mash the sweet potatoes until smooth.

Step 4: Stir the butter, cream, maple syrup, orange juice, and orange zest into the sweet potatoes. Taste the potato mixture for seasoning, adding more salt if needed, then stir in the eggs.

Step 6: Bake the casserole at 350°F for 30 minutes, until the top is browned and crisp.

Make-Ahead Tips

Make the casserole in advance to keep your time in the kitchen the most efficient. Here’s how you’ll do it:

  1. Freeze the sweet potato mash – If you’d like to really knock out some of your Thanksgiving prep in advance, you can freeze the sweet potato mash – just leave out the eggs. You can either transfer the sweet potato mixture from the freezer to the fridge 2 days in advance or reheat it on the stove or in the oven. Once it is thawed, stir in the eggs, put it in the casserole dish, and top with the crumble.
  2. Make the full casserole – You can assemble the full casserole up to 2 days ahead of time, then bake it on the day of. If you do this, add an extra 10 minutes to the cook time since it will be cold from refrigeration.

If you like super smooth, silky sweet potatoes in a recipe like this, feel free to use a food processor or immersion blender to mash the potatoes rather than a handheld potato masher.

How to Serve

Serve your sweet potato casserole alongside all of the classic Thanksgiving dishes. Here’s my ideal menu, in case it’s helpful:

How to Store and Reheat

Store leftover sweet potato casserole in an airtight container in the fridge. Stored this way, it’ll last for up to 5 days.

This sweet potato casserole also freezes really great. To do this, we recommend packing any leftovers up in individual servings and then freezing.

Reheat the casserole in a 350°F oven for 15-20 minutes or microwave it for 2-3 minutes.

Two bowls of sweet potato casserole, each with a fork, sit next to the baking dish, of more casserole, from which they were taken from.

Frequently Asked Questions

How do you know when sweet potato casserole is done?

Good question! You’ll know that your sweet potato casserole is done when the pecan topping is browned and crisp.

Can you use yams in this sweet potato casserole recipe?

Yes! In fact, most of the time, yams are actually mislabeled and are really just orange sweet potatoes. A true yam has a dark, almost black skin and is white inside. If you happen to come across a true yam, it can’t be substituted for sweet potatoes, but know that it is fine to use the orange varieties here!

What is the difference between sweet potatoes and yams?

As mentioned above, true yams have really dark skin and are white on the inside. Sweet potatoes, on the other hand, are orange on the inside. Yams are typically starchier and higher in fiber, while sweet potatoes are slightly sweeter and creamier.

  1. I would like to make this dish so my vegan family members can enjoy it as well. Do you have a suggestion for the best egg substitute? I wasn’t sure if flax egg, or possibly Bob’s Red Mill Egg Substitute would work well? Thank you!

    1. Hi Dara! You can omit the egg completely if you want (it will just have a little less structure – this is actually how we prepped it in the office because we forgot the egg, and it turned out just fine!). Or we’ve done extensive research on egg substitutes that you can find here. I hope that’s helpful! -Team FF

    1. Good question, Jaime! The reason it goes into the oven once assembled is to crisp it — I don’t know that the slow cooker will get it crispy, but if missing that crispy texture is okay with you, I say go for it! It’s certainly a great place to keep your casserole warm!

  2. 5 stars
    So yummy! Made this without sugar, maple syrup, and subbed coconut flour for the all-purpose. SO GOOD! Ate it for breakfast today and probably every day this week.
