How 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.

Make-Ahead Instructions

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. Once cooled, cover the dish tightly with plastic wrap. 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.

Instructions 

STEAM THE SWEET POTATOES

  • In the INSTANT POT (preferred method): Place a rack in the instant pot and add 1 cup of water. Place the washed sweet potatoes on top of the rack. Cook on MANUAL (high pressure) for 15 minutes. Allow the sweet potatoes to natural release, until the valve drops on its own.
  • On the STOVE TOP: Place the sweet potatoes (whole and unpeeled) in a large pot and covering with water. Cover with a lid and bring to a boil. Boil for 10 minutes. then puncture each sweet potatoes 3 times. Boil for another 20-30 minutes until cooked through.

Notes

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.
Just be sure to NOT cut the sweet potatoes into small pieces to steam them. The will absorb too much water and make the filling wet/watery.
MAKE IT AHEAD: Prepare the sweet potato filling and smooth it into the baking dish. Cover tightly with plastic wrap. Prepare the topping in a separate container. Store everything in the refrigerator for up to 3 days. When ready to bake, top the sweet potatoes with the pecan mixture and bake as directed.
MAKE IT DAIRY-FREE: Use dairy-free butter in place the butter. 
MAKE IT EGG-FREE: You can easily omit the egg from the filling to make this egg-free.

  1. Want to try this for Thanksgiving next week, but wondering if I can use Almond flour for the flour as have a lot of it and it is gluten free. Anyone know? Sounds delicious???

    1. Unfortunately almond flour won’t work in this recipe! It has very different properties than gluten-free 1:1 baking or all purpose flour. Sorry about that!

  2. 5 stars
    One amazing recipe! I made with a mix of Japanese sweet potato and American, omitted sugar and it was just amazingly good!
    Thanks for the recipe!

  3. 5 stars
    Amazed by how much everyone enjoyed this when someone brought it to Thanksgiving.I can’t wait to wow my next guests!

  4. 5 stars
    Absolutely love this recipe! I made it gluten and dairy free. I used country crock plant butter. I will be making it every yr from now on. Thank you!

    1. Hi! Planning on making this tomorrow, can I use coconut flour or bobs red mill gluten free 1 to 1 baking flour?
      Thank you!

  5. 5 stars
    Thank you so much for this recipe! My family loves it! I love how easy it is to make the sweet potatoes in the instant pot too! Have you ever tried to make regular mashed potatoes with this method before? Steaming whole and then peeling? I would love to know if it works well for those.

  6. 5 stars
    Tastes like the family recipe (containing gluten) my grandmother used to make. Your recipe was enjoyed by all at Thanksgiving! My husband requested I make it again – ASAP. Thank you!

  7. Hi there! Excited to try this recipe this Thanksgiving! I can’t use butter (kosher), so wondering if you would recommend a good butter alternative that would also crystalize, or if coconut oil is just as good? Thank you!!

    1. Earth Balance buttery sticks or Miyoko’s Vegan Butter both work great. I like those because they still have a buttery taste but coconut oil will also work.

  8. 5 stars
    This was unbelievably good! I have celiac disease and wanted to make something everyone could enjoy, that didn’t taste gluten free. This will be my go-to dish!

  9. 5 stars
    My sister made this a few years ago and this is now out families favorite sweet potato casserole recipe!! Sooo delicious!!

  10. Thank you so much for this recipe! My daughter has PKU so we will be leaving out the egg or using an egg replacer and we will make this dish with only the topping on half of it since she can’t have the nuts, but I’m happy that she’ll be able to have this with everyone else!
