A healthy and lighter classic sweet potato casserole sweetened naturally with pineapple and golden raisins. To be honest with you, I’ve never understood the whole marshmallow thing but after making this recipe, I totally get it! It’s the perfect mix of sweet and savory and the colors are just beautiful making this a wonderful addition to your Thanksgiving table. Also great for Christmas or Easter! Some of my favorite Thanksgiving side dishes are Cranberry Pear Sauce, Green Bean Casserole and Brussels Sprouts Gratin.

    I tried this today. The only thing I will change when I make it again, which I will, is decrease the pineapple as I thought it was a bit overpowering.

  2. This year will be the 4th year in a row that I’ve made this casserole for thanksgiving so I decided it was time to rate it and make a comment. It’s been a hit every year. Our friend that doesn’t normally like sweet potatoes loves this casserole and normally has 3rds of it. We rarely have any leftovers. 

    1. KDAHL, did you try making this ahead and freezing? One year later, I have the same question. I would like to make it ahead for Thanksgiving. If you — or anyone else — can give advice on this, I would be thankful!

  3. Make life easier by boiling the sweet potatoes in their skin until fork tender, cool and skins slide off. Mash with a fork or potato masher and carry on with the recipe.

    1. I took this a step further and pierced them with a fork a few times, microwaved them for about 8 minutes in the morning, and popped them in the fridge. When I got home from work the skin just peeled right off and it mashed easily!

  4. As a Canadian, I have never tasted the traditional sweet potato casserole, so I have nothing to compare to. I thought that the pineapple could be reduced by 2oz and that the cinnamon could be doubled. I pureed the sweet potato along with the pineapple and raisins using an immersion blender. I cooked this in a 9×9 pan, divided it into 9 servings, and calculated the points plus to still be 3. Delicious!

  5. Any reason you went with Golden Raisins over regular? I have regular raisins and would prefer to just use what I have- but I am making it for Christmas dinner, so I don't want to skimp if golden raisins do the trick! Thanks!

  6. Would substituting bananas for the pineapple make this too dry? I don't really care for sweet potatoes, but my grandfather loves them. Extra bonus for this being a dish that is better for him than those canned yams and sugar heavy sweet potatoes he usually goes for on Thanksgiving.

    I'm hosting a pre-Thanksgiving family dinner tomorrow since I'll be traveling to Michigan next week to visit my in-laws… And this sweet potato casserole is on the menu! I think I'm going to prep it tonight!

  8. What a great recipe 🙂 thank you sooooooo much I had a great time making this. I blogged this recipe . If your interested and wanna check out my blogg just let me know

  9. OH… I forgot to mention that I substituted the agave for brown sugar, and did not add the raisins or walnuts. Perfect!

  10. I tested this out tonight and it was great!!! I can not wait to make for Thanksgiving. I love sweet potato casseroles but hate how they are always too sweet and fattening. I had the browns sugar ready in case this was not sweet enough but there was no need! We all had seconds tonight. Thank you 🙂

  11. OMG, soooo good! I had this at a potluck at work and had to hunt down the person who made it for the recipe. The pineapple and raisins add a natural sweetness to the dish that is absolutely addictive!

  12. Looks amazing, I can't wait to try it. I'm not a big fan of pineapple and raisins. Will it effect the outcome of the dish if I omit them?

  13. My sister makes a sweet potato casseroe for every Thanksgiving Family Meal – I am going to send this to her since we all like to eat healthy

    I boiled the sweet potatoes the night before Easter to save time the next day. I had no agave so I used 1.5 tsp brown sugar. I also run the pineapple thru a mini food processor first so it would be smoother. Although it didn't give me the good holiday fuzzies (like the sweet potato pie – yum) I liked it enough to probably make it for a regular dinner side dish. It's healthy enough. Caution…If you plan to bake this in a toaster oven be careful. Mine browned VERY quickly (it still had 9 mins left!). I guess the delicate marshmallow topping is too close to the heating element in a toaster oven. Also, I agree with the review that mentioned the strong pineapple flavor. If pineapple is not your favorite thing this recipe may not work for you.

  15. This came up under Vegan, but marshmallows are not Vegan. That can be very misleading for someone who may just be starting out Vegan. Please consider tweaking the recipe to include that info or re-categorizing the recipe. Otherwise, this recipe sounds amazing!

  16. I love sweet potatoes but haven't liked them in casseroles even though I keep trying. This recipe was great. Glad to finally have a recipe that makes both me and the sweet potato casserole lovers happy — thank you!

  17. I can't WAIT to make this for Thanksgiving tomorrow. My family is finally letting me cook something (instead of bringing cheese and crackers). Thanks for providing a healthy but still fun version!

  18. I just cooked this up, to the point where you add the nuts and marshmallows and bake. I tried the mashed-mixture and I feel like the pineapple is a bit overpowering. My immersion blender didn't crush up the pineapple any more than it already was and if you try a bite with a pineapple piece in it, it's really strong. Will this maybe mellow out during the baking? I'll bake it off tomorrow to be ready for Thanksgiving dinner.

  19. This is so YUMMY! I made it a couple nights ago. and im boiling yams as i type this. Im using yams cause thats what i had. this time im gonna use brown sugar cause i dont have agave. I absolutely LOVE LOVE LOVE this site.

    I'm so happy you all liked it.

    To the person who doesn't like pineapple, try the creme brulee sweet potatoes instead!

    Yes, you can prepare this the night before!

    Persophonie, oh how special that must be!!! You're grandad made History!

  21. I laughed to see this recipe on Pinterest! The White House Cookbook was published by my Great-Grandfather, from Saalfield Publishing. Someone else has purchased the rights to this cookbook and is re-publishing it. Glad to see that this recipe is from it and is a hit!

    I have never been a huge fan of sweet potatoes and marshmallows. Too sweet for me. But since I am a huge fan of your recipes, I decided to give it a go. I absolutely loved them!!! It wasn't syrupy sweet like a typical sweet potato marshmallow dish at all. This will defintitely be on my list to make for the holiday meals we will be going to. I did leave out the raisins, though. Still not a raisin fan. 😉

  23. I was thinking of trying this out for Thanksgiving this year, but I am concerned about the pineapple. Can you taste it? I am a huge fan of Boston Market's mashed sweets with marshmallows, so thought this might be good instead. Would you make this and leave it out, or try the brulee recipe and add marshmallows?

  24. OMG! This is a dish that has been on our Thanksgiving table for years. But it has been the dish loaded with a lot of sugar and butter. So happy i now have a lowfat version to try. So looking forward to it! Thanks Gina.

  25. I made this for my mom the other day (probably the 5th recipe of yours I've tried) and we loved it. Dad had no idea there was no sugar in it! I love your recipes, they are so good and amazingly easy to make!

  26. Looks great! I went shopping for the ingredients the other day and the "sweet potatoes" I saw in the produce section where more white in color. The "yams" I saw were more orange like your pictures. So do we need "yams" for this recipe or "sweet potatoes"? I have googled the difference and the "yams" seem to be the ones to use for sweet casseroles.

  27. Instead of t-shirts and shot glasses I always buy a local cookbook when I go on vacation – the White House one you mentioned above was the one I bought on my first visit to D.C. two years ago 🙂

    Oh and recipe looks amazing too, I think I'm going to try it out for Thanksgiving!

    Oh wow. Wow this looks AMAZING. I'm English so the concept of a Sweet Potato Casserole is totally foreign to me, but I want it in my tummy pretty soon.

    Thanks for letting me know this isn't vegan!

    Canned pumpkin should work, I don't have a cup size for the serving, sorry.

    1. Us vegans can just use vegan marshmallows! I know that Sweet and Sara and Dandies both make vegan marshmallows. I love sweet potato casserole and will be trying this recipe soon. Thanks!

  30. would this recipe work if i substitute the sweet potatoe for canned pumpkin? also do u know the measurments for a serving size? (ex:1/4 cup per one serving) thanks!

  31. This sounds fantastic! The only thing is that this is labeled under "Vegan", but the marshmallows would have to be omitted for it to be vegan (since most are made with gelatin, an animal byproduct). It would probably taste just as yummy without! 🙂

  32. This was my first time trying a recipe from the site, but I've been looking for a while. I replaced the sweet potatoes with butternut squash (since I had bags pureed in the freezer). I also omitted the raisins. When I recalculated the info, I found I could get 1/6th of it for 2p+. Very filling and very tasty. Thanks for all the great ideas.

  33. beautiful, however, would like to add that as this is listed in Vegan section that the marshmellows are not vegan.

    This looks totally amazing! I am trying it this weekend, and then adding it to my Turkey Day menu plan… Gina, thanks for always sharing such wonderful recipes. You have utterly transformed dinnertime at my house.

    My inlaws make a fabulous sweet potato pecan recipe using marshmellows too. But this one seems to push the envelope. I will suggest it this year and do a side by side comparison.

  36. Beautiful photos! I think this lightened up version probably tastes better than the original. just sayin.

  37. This is a family favorite that has been off the table for a while but will make a reappearance this Thanksgiving! My crew will be thrilled so thank you.

    The book sounds quite interesting. Never gave a thought to making my dress "incombustible"!

    You can use brown sugar in place of agave and visa versa. I'm sure canned sweet potatoes would work just as well.

    Any changes you make to this, you should check the points on recipe builder.

    I didn't weight this, forgot to so If you want to know your serving size for sure, weight it, then divide by 10.

  39. This looks delicious! I can hardly wait to try it. I re-joined WW on Monday and know I will have great success due to your recipes! Thank you for making it so much easier for all of us to follow a plan and feel good about ourselves!

  40. I have never made/had a sweet potato casserole before, but love sweet potatoes. I might just have to give this a try!

    Oh, this one looks very tasty. And I would love to win that book. If I don't win, I probably will buy it. I am fairly new to your blog and I have been enjoying it very much.

  42. Could it be done with the canned sweet potatoes? I am fond of fast on Holidays because I have a lot and I mean a lot of cooking to do!

  43. Hi Gina! how do i divide up the servings into 1/10th??? and what if i don't like raisins or pineapple in it? would that change the calories or points? thanks!

  44. I'm definitely passing this along to my mom who likes to make a sweet potato casserole for Thanksgiving and then goes home with a 3/4 full dish.

    Im trying this for the coming Holidays. I make one like it but have never tried the pineapple in it. Looks wonderful!

  46. This looks absolutely DELICIOUS – definitely gonna give it a shot. A great way to use up those last few sweet potatoes I've not used yet. 🙂 Thanks a bunch!

    This is amazing. I used to eat sweet potato casserole like it was my job.. until I cleaned up my eating. Now I can enjoy it again!! Thanks!

  48. This recipe looks awesome! My recipe is insanely fat drenched. I'll definitely try it! That cookbook looks awesome.

  49. That was the first thing that I thought! Never been a big fan of sweet potato types of dishes with marshmallows…. I grew up in the D.C. area though. And I love agave! I admire you for making the recipe first and then tweaking. That's the way it should really be done. I'm sure my very Southern husband from Georgia will love this! And his family!

  50. this sounds delish! I am the only one in my house that likes it so I would have to eat the whole thing alone!! Only one point over my WW daily allowance!

  51. This was my absolute favorite dish at Thanksgiving growing up! I'm so glad you made a skinny version so I can enjoy it guilt free!

  52. This looks really great and a great substitute for the butter drenched sweet potatoes I generally make at Thanksgiving!
