Thanksgiving is almost here, and it’s a great time to plan recipes ahead if you or someone you are cooking for has to eat low sodium. But, like all our recipes, this easy sweet potato casserole is SO flavorful, and no one will miss the salt!
I’ve been sharing out low sodium holiday recipes (you can check them out here!), and classic sweet potato casserole is one of the easiest to make. My family always topped ours with marshmallows growing up, but I wanted to make this version a bit more adult-friendly with brown sugar and pecans.
The result? A creamy, buttery, delicious side dish, that it just the right amount of sweet with no salt added!

The Best Holiday Sweet Potatoes
Our household is half-American (me) and half-Canadian (hubby), so that means we get TWO Thanksgivings every year! I get a few chances to develop great low sodium recipes for our families and us to enjoy.
After a few attempts, this sweet potato casserole recipe was absolutely perfect! The first one I made was too sweet (I used more sugar + vanilla), and the second wasn’t sweet enough. This one was just right! I kept the sugar out of the main part of the casserole, and only reserved it for the topping. I preferred that much better than adding sugar to the filling.
If you like a sweeter casserole, you may want to add an additional tablespoon or two of brown sugar to the sweet potatoes when mashing. But I found the recipe below to be the best of both worlds!
Ingredients You’ll Need
See the recipe card below for a full list of instructions and ingredient amounts!
- Sweet potatoes – I got some fantastic sweet potatoes in my veggie box – they were organic and absolutely delicious! You can use any variety you find at the store too.
- Unsalted Butter – we only use unsalted butter in all our recipes, it’s a great way to cut down on your salt & sodium intake with a simple swap. Butter is used twice in this recipe – in the sweet potatoes and also the topping.
- Egg – to keep the sweet potatoes together when baking.
- Milk – You can use any variety you have on hand. The milk is great to add a bit of creaminess, and also thin out the sweet potatoes into a delicious mash.
- Brown sugar – for the topping, adds so much flavor! If you want to use a natural sweetener, maple syrup or agave nectar would be great substitutes.
- All Purpose Flour – for the topping. Or substitute a gluten free mix, if needed.
- Pecans – I used raw, unsalted pecans for this recipe! Since the nuts are being baked for 30 minutes on top of the casserole, there is no need to get roasted nuts.
Can You Add Marshmallows?
Absolutely! you can add marshmallows instead of the brown sugar pecan topping, or add them instead of the brown sugar & flour (and make topping with pecans, butter, and marshmallows).
If a hot dish of sweet potato casserole with a beautiful pile of toasted marshmallows is a must on your holiday table, then I say go for it! 🙂
How To Make This Recipe
- Prep your sweet potatoes: peel (if desired), and roughly dice each sweet potato into 1-2 inch chunks. Place them in a large pot, and add just enough cold water to cover the sweet potatoes by an inch. Bring to a boil, and cook for 10-15 minutes until fork tender. Drain and place sweet potatoes back into the pot.
- Add the milk and half of the butter (save the remaining 1/4 cup for the topping), and the egg to the sweet potatoes and mix well to combine. Mash with a potato masher or an immersion blender, until sweet potatoes are smooth and creamy. Add them to a 13 x 9 inch casserole dish.
- Preheat oven to 350 degrees Fahrenheit. Crush pecans, and add them to a small mixing bowl with the brown sugar and flour. Cut the butter into small cubes or mash with a fork, and add to the bowl. Mix with a fork until well combined. Add the topping in an even layer on top of the sweet potatoes.
- Bake casserole for 25-30 minutes, or until topping has browned and potatoes have warmed through.
- Serve hot. Refrigerate any leftovers in an airtight container for up to 4 days.

Making this for Thanksgiving after trying it and loving it
Does it say when to add the milk? I’m assuming before mashing?
Hi Margaret – add the milk in step 2, before mashing! Let us know how it turns out 🙂
– Kelly
This was easy to make & so so good! I just realized I forgot to add the milk but it was perfect without it. My husband really
Loved the pecan topping. So happy to find a great low sodium side that everyone will enjoy.
A perfect side to any meal
The milk is included in the ingredients but not in the instructions. I did notice before putting the topping on, and scooped out the mash, and then added it. Perhaps you could edit your post to include adding the milk earlier?
The dish turned out really tasty. Didn’t miss the salt at all.
Hi Martin,
I just edited the recipe, thank you so much for the note, and apologies for any confusion!
