Allergy-Friendly Sweet Potato Casserole Recipe (2024)

This year, grace your holiday table with a sweet potato casserole so versatile (almost) anyone can eat it no matter their dietary needs, and so good your family and friends will request it not only in November or December… but July, too! This recipe is or can easily be made gluten-free, grain-free, dairy-free, egg-free, GAPS and Paleo-compliant!

I’m putting myself on the line here…

This sweet potato casserole hasn’t won any awards, or a blue ribbon at the State Fair, or anything like that.

YET, I freely admit that I never liked sweet potatoes until I created this recipe. I make it for my family year-round, take it to cookouts and potlucks, and share it with many friends and family! It’s so good!

So that is why it’s The Best Sweet Potato Casserole Ever. 😉

Why I Love This Recipe

1. It doesn’t have the traditional marshmallow topping.

Maybe you love marshmallow toppings, and if you want to stick with it, I promise I won’t mind. I personally can’t stomach the thought of putting store-bought marshmallows on such a healthy dish. And unfortunately, all the homemade marshmallows I’ve tried melt into a white puddle during baking. It’s a yummy white puddle, but seriously lacks in presentation if you know what I mean. 😉

2. And, it’s versatile!

You can adapt it to just about every eating style out there!

• GAPS? Sure, use butternut squash (unless you’re allowed sweet potatoes), ghee or coconut oil, and raw honey.
• Grain-free/gluten-free? Absolutely! This recipe doesn’t call for a smidge of traditional flour, but uses coconut flour instead.
• Dairy-free? Yep. Substitute ghee or coconut oil for the butter in the crumble topping.
• Paleo? Depends on what version of Paleo you’re following. Some say “yes” to sweet potatoes; others say “no”.
• Egg-free? Feel free to leave the eggs out completely or substitute a flax or chia egg.
• WAPF? Yes! Use soaked/dehydrated nuts in the topping, and you’re good to go.

Not following any particular eating style? Well, put this casserole on your holiday table this year, and I promise no one will ask you if it’s health food.

We have a friend who loves this casserole so much that he asks me to bring it every time we are invited to their home for supper — even in June! He eats it for dessert!

Ingredients Needed

• Sweet potatoes — Or butternut squash!
• Eggs — Choose organic and/or pastured eggs if possible. If you need to omit the eggs, use an egg substitute instead such as a flax egg or chia egg. Here’s how to make a flax or chia egg.
• Full fat coconut milk — Here’s how to choose the best coconut milk for your family’s needs.
• Sweetener of choice — Choose between raw honey, maple syrup, or coconut palm sugar. I like coconut palm sugar best in this recipe.
• Coconut flour — I don’t recommend substituting for coconut flour, as it is a grain-free, nut-free flour with unique characteristics! Learn more about coconut flour here.
• Spices — Ground cinnamon, nutmeg, and all spice.
• Sea salt – We recommend a mineral-rich salt.
• Nuts of choice — I recommend almonds and walnuts, preferably soaked and dehydrated first to improve their nutrition and make them easier to digest. Learn how to soak and dehydrate nuts here!
• Unsweetened shredded coconut
• Chia seeds
• Butter — Preferably grass-fed. Or use coconut oil or ghee.

Supplies Needed

• Large pot — For boiling the potatoes. Or bake the potatoes instead using a parchment paper-lined cookie sheet.
• Medium-sized mixing bowl — Use this for making the crumble topping.
• Pastry cutter — For cutting the butter or coconut oil into the crumble topping. You can use a fork instead.
• Potato masher — Or use your hand mixer or stand mixer.
• 2-quart baking dish — Such as a glass casserole dish.

Sweet Potato Casserole Recipe

1. Preheat the oven.
2. To boil the potatoes: Peel them and cut into large chunks. It doesn’t matter how big they are as long as they are all about the same size. Put sweet potato chunks in large pot and fill with water until potatoes are covered. Bring to a boil over high heat, and boil until soft (but not mush) when pricked with a fork. Once soft, drain water away. Reserve potatoes in the pot.
3. To bake the potatoes: Cut the ends off the sweet potatoes, and prick each potato several times with a fork. Set on a parchment-lined cookie sheet, and bake until soft. When the potatoes are soft, remove them from the oven and turn the oven temperature down. Carefully, remove the skins from the sweet potatoes. They will be VERY hot, but it is much easier to get the skins off when the potatoes are hot than when they are room temperature or cold. You can use a butter knife to help get the skins off more easily.
4. Transfer the peeled potatoes to a large mixing bowl (or use the pot you boiled them in). You can even use the bowl of your stand mixer. Mash the potatoes with a potato masher, a hand mixer, or your stand mixer.
5. Add the rest of the casserole ingredients to your mashed sweet potatoes — eggs, coconut milk, raw honey, coconut flour, salt, and spices. Mix until well combined and fluffy.
6. Spoon into a greased baking dish.

1. While potatoes are cooking, combine all topping ingredients in a medium-sized mixing bowl.
2. Using a pastry cutter, cut in the cold butter until the topping has the feel of wet sand. Set aside.
3. Cover casserole filling with the crumble topping.
4. Bake until golden brown on top, and enjoy!
