What is the best way to steam sweet potatoes for sweet potato casserole?
How you steam the sweet potatoes is an important step to ensure your filling comes out smooth, but not watery. Lately, my favorite way to steam the sweet potatoes is in the instant pot. It’s so easy to do and the sweet potatoes come out perfect every time.
Cooking Sweet Potatoes in the Instant Pot
- Place a rack in the instant pot and add 1 cup of water.
- Place the washed sweet potatoes on the rack and cook on MANUAL (high pressure) for 15 minutes.
- Allow the sweet potatoes to natural release until the valve drops on its own.
- The sweet potatoes will be soft and easy to peel!
If you don’t have an instant pot you can also steam the potatoes on the stovetop. You do this by adding the sweet potatoes (whole and unpeeled) to a large pot and covering with water. Cover with a lid and boil for 10 minutes. Puncture the sweet potatoes 3 times, then boil for another 20-30 minutes until cooked through.
Can I make this sweet potato casserole in advance?
This sweet potato casserole is a great make-ahead dish. I’m always looking for recipes I can make in advance before Thanksgiving. This one turns out great!
Up to 3 days in advance you can prepare the sweet potato filling and smooth it into a baking dish. Then prepare the topping and store it in an airtight container. Store everything in the refrigerator. When ready to bake, top the sweet potatoes with the pecan mixture and bake as directed.
I hope you enjoy this sweet potato casserole as much as we do! It’s a long-time family favorite and nobody will be able to guess it’s gluten-free. (PS I think it tastes delicious straight out the fridge next day!)

Ok, making this for Thanksgiving again this year.
Maria says
Hi. I am making this tomorrow for Easter & only have a 2 qt sized glass dish. Do I need to adjust the baking time? My friend made this months ago & I loved it so I can’t wait to eat it again! Thanks.
Wynne says
Thanks for the recipe! I use almond milk…. To make it MUCH easier you can boil the sweet potatoes WHOLE, let them cool (or to make it faster, dump out the hot water and put cold water with ice to cool faster). Drain the potatoes, or be very gentle if you can’t wait. The peeling will tear off easily. I do this with white potatoes also.
Connie Martin says
While this dish is very flavourful, mine was soupy—that is, the sweet potato part. It wasn’t at all like the photos here. That’s how I would like it to be, but it was extremely soupy. I don’t know what I would’ve done wrong. I went completely non-dairy, so used coconut oil solid form (the only way I can find it anyway in the stores). Can someone advise?
Cassie says
Is this soy free?
Tina says
Loved, loved, loved this! It was absolutely delicious! We used walnuts (the store was out of pecans). This will be a favorite for many years!
Erin Collins says
So glad you liked it! Walnuts would be delicious too!
Jackie says
Only using 3 cups of the Sweet Potatoes looks too watery to me. Does it thicken when baked?
Erin Collins says
The consistency can depend on how watery your sweet potatoes are when they are mashed. I make sure to leave my sweet potatoes in larger chunks (3-4 inches) when steaming them so they don’t get too watery. Smaller chunks absorb more water and create a more watery mash. You can always add more sweet potatoes or less coconut milk to the consistency you like too. The mash won’t thicken much in the oven!
Natalia says
This is my very first sweet potato casserole and it was a hit! I am allergic to gluten so most store bought Thanksgiving sides are out of the picture. I prepared this as a trial several days prior to Thanksgiving to see how it comes out. It was delicious!!! My 4 y.o. twins loved it, one of them even asked for seconds! Thank you! Fantastic recipe!
Erin Collins says
So glad you like it! 🙂
Amelia says
I loved this dish! But I really hoped the mash bit would be more like ‘mash’, thicker and less liquidy. Could be because I used coconut oil… any advice would be much appreciated!!!
Erin Collins says
It probably has to do with how you steamed your potatoes and how much water the sweet potatoes naturally contained. When I’ve used smaller sweet potatoes and steamed then they have more water. I would try using large sweet potatoes and just add less coconut milk so you get the consistency you like. I hope that helps!
Dee Dee says
We love the praline topping of the unmodified recipe. I keep hoping to find a gluten free that replicates the same crunchiness. I made this version anticipating that it would be just what I was looking for. While it was good, I am looking for perfect. 🙂 Wondering if results are better with coconut oil than butter? Or one flour better than another? The topping was drier than normal so it didnt melt and crystalize.
Jen says
Could I use a rice flour or sorghum?
Erin Collins says
You could try it – the topping might be a little more grainy though!
Sasa says
Hi there!
Could I use a butter substitute made from coconut oil in this recipe instead of the butter? If so would I measure it out the same?
Erin Collins says
Definitely! That should work great!
Karen says
This got rave reviews last night at our dinner – thank you!
Lynsie Foster says
i can’t have gluten, rice, or corn. Do you think almond flour or coconut four would work?
Erin Collins says
Hi Lynsie! Have you tried my grain-free flour blend? It would work perfectly here. That would be best, but you could try half almond flour and half starch (like arrowroot or potato) for the flour as well.
Megan Vaeth says
So using grain free will be just as good ?
Malyssa says
Would have any tips on how to make this in the crock pot??? I don’t think my oven is big enough for this and a turkey lol
Erin Collins says
I think this might work in the slow-cooker, but the topping won’t get as crispy. You could spread the filling on the bottom, then top it with the pecan topping. I would try cooking it on low for 4 hours. I hope this helps! Let me know if it works out.
