Mom’s Amazing Sweet Potato Casserole Recipe

Mom’s Amazing Sweet Potato Casserole Print

Sweet Potato Casserole is an all time favorite in our home during the holidays, especially on Thanksgiving.  When my grandmother got older, my mom took over Thanksgiving dinner.   We always had a sit down meal for at least 20-30 people and mom’s Sweet Potato Casserole has become a staple Thanksgiving recipe for us.

I used to feel like this was the day I worked the banquet hall!   It was during the holidays growing up that I learned from my mom how to cook dozens of different dishes for an army of people and how to get everything out hot and delicious.  My mom is the master at dinner parties and has taught me everything I know now about how to pull off a huge dinner with style.

This recipe is only one of the fabulous dishes she makes. I actually save extra room on my plate every holiday for this amazing sweet potato concoction.  It is sort of a cross between a savory side dish and a decadent dessert.  I would rather miss the Turkey than this dish.

Trust we when I tell you that this will be everyone’s favorite side dish. It’s perfect for bringing to a dinner party too. If you are going to someone’s home this holiday, volunteer to bring this dish and it will be the “belle of the ball.”

The holidays are a time when I like to indulge, so if you are looking for a light recipe, this one isn’t it.  You can scale back on the butter and the sugar if you want to make it lighter, but I figure I’m only eating it once a year so I’m going for the full fat version and loving every bite of it.  Give it a try and let me know what you think.


  • 4 large sweet potatoes, peeled cooked and mashed
  • 1 cup sugar
  • 1 cup unsalted butter, melted
  • 4 eggs
  • 2/3 cup evaporated milk
  • 2 teaspoons vanilla
  • Pam cooking spray, to grease pan


  • 2 cups brown sugar
  • 1 stick of unsalted butter, softened
  • 2/3 cup all-purpose flour
  • 2 cups pecans or walnuts, chopped
  • 1 teaspoon cinnamon


Preheat oven to 375 degrees.

In a large bowl, beat together all the filling ingredients with an electric mixer. Pour into a greased, 9×13-baking dish.  In a separate bowl, mix all the topping ingredients together with a fork to form a crumbled mixture. Spread crumb mixture on top of casserole and bake in the middle of the oven for 35-40 minutes.  Remove from oven and allow casserole to cool for at least 10-20 minutes before serving.

Cook’s notes:

To cook the sweet potatoes, simply peel the potatoes, slice them in cubes and boil in a large pot of boiling water until softened.  It usually takes about 15-20 minutes depending on the size of the cubes.  Strain and mash with a hand mixer or spoon and allow them to cool slightly before mixing in other ingredients.

Make ahead tips:

This dish can be easily made a day or two ahead of time covered with plastic wrap and placed in the refrigerator until ready to bake.  Be sure to remove it from the refrigerator about 15-30 minutes prior to baking so it won’t be ice cold going into the oven. Remove plastic wrap and bake uncovered. It may take a little longer to cook if it is cold so just give it some more time when you bake it.

I made this (even though I REALLY hesitated at putting a whole cup of butter in!) for Thanksgiving and everyone freaked out! I am always asked to bring my ‘famous’ sweet potatoes, but was tired of making the same old thing. My husband was mad at me for trying a new recipe because he loves the ones I always make, but it was unanimous: I am to bring your mom’s sweet potato casserole every year from now on! Just wanted to say thanks for sharing. I am going to use the topping recipe to make some sweet potato muffins, too! Oh, I also made the chicken Gloria casserole last week and everyone loved that, too. :)

May says:

I have doubled the recipe, how long should the casserole bake? Thanks!

May I am sorry I didn’t see this yesterday. I was knee deep in my cooking. I hope it turned out well. The cooking time will vary with the size of the baking dish.

Let me know how it turned out.

kelley says:

hi my name is kelley and i was woundering how many serving’s does your casserole make im trying to make it for 20 people…

Hi Sugar,

Thank you for being so clear on ingredients and instructions. I am new to cooking and understood everything you wrote. I am cooking for 20 people. I saw that you replied to a prior comment that this dish feeds 15-18 people. If I was wanting to feed 20 people should I double your recipe ingridients? Also, If i were to double your ingredients what size baking dish would you recommend for me to cook with? Lastly, if i doubled your ingredients, would I continue to bake the sweet potato casserole for 35-40 minutes? Or would I increase the baking time because I doubled the ingredients? Sorry for all the questions. I’m a newbie! My kitchen ware consists of: plates, cups, untensils, one pot and one pan, haha. I am going to be buying baking dishes and etc today. :)

Thank you again for sharing!! I’m excited to try your recipe

Happy Thanksgiving!!!

Thank you so much for the sweet feedback. I don’t think you need to double it. You should be able to make 1 and 1/2 and that will be plenty. Just use a casserole dish that is large enough to hold the increased amount. I say pick up a disposable tin one at the store maybe even a deep dish lasagna pan in a 9×13 will work for 1 1/2. If you double it you can pick up a 16-inch pan. Sort of the size you would do a roast in. The way I like to gauge pan size is I usually put the potatoes in the pan and see how much room they take up leaving room for the other ingredients too gives you a better idea of what will work. If you need any help just let me know.

Happy cooking and have a blessed Thanksgiving.


Shannon says:

How many will this recipe feed I am cooking for 45-50 This sounds so good I cant wait to make.Happy Holidays

We usually make one as a side for about 18 people. Double should be fine. If you are having a lot of other side dishes. You can also make 2 1/2 times the recipe just to be safe too.

Enjoy and Happy Thanksgiving

Good morning to you Sugar!
I had to let you know how much my family loved your sweet potato casserole! It was a big hit and I must say that very little was left and of course gone the next day. I used walnuts instead of pecans just because that’s what I had on hand. I look forward to trying all of your recipes! Thank you!

I’m so glad that everyone loved the casserole. Thanks so much for the feedback. It makes my day to hear that other people are making recipes that my family has been enjoying for many years and sharing them with their families. Be sure to try some of the other ones I list and make sure you tell your friends and family to join my email list so they too can get notified when I add new ones. :)

Lindsey says:

Sugar….I have struggled over the years to find a dish that I can bring to dinner and everybody say how wonderful it was!! I love to cook, however it is very hard to stand up against all the rest of the great cooks in my family. I am excited to make your recipe in hopes that everyone will love it so much that it becomes my specialty!! Thank you for sharing and Happy Thanksgiving!!

Profile photo of Sugar Profile photo of SugarSugar says:

Oh Lindsey I know how you feel. Almost all the women and a lot of the men in my family are great cooks, so I understand how you feel. I think everyone will love this dish. My Grandmother always told me that she would put a little love into her food. When I cook I think of how much I enjoying making things that will bring people pleasure. “Cook with love” and you can’t go wrong. Happy Thanksgiving.

Nancy says:

Hi Sugar,

I can’t wait to try this out on the family for Thanksgiving! One question though, how many people does it serve??

Profile photo of Sugar Profile photo of SugarSugar says:

Nancy, I would say about 15-18 people. I made it last week so I could do the photos and there were 9 of us for dinner and we ate half of it. Be sure to let me know how you like it. Happy Thanksgiving. :)

Lee Cantor says:

Hi Sugar-As you know I work with your mom. There were a bunch of us in the office talking about Thanksgiving recipes, and she said we had to try your (her) sweet potato casserole recipe & asked me to pull it up on the computer. Well, you’ll be happy to know that all 5 of us are going to make it for our families & guests! It looks and sounds so fantastic my mouth is watering already! BTW-she was very proud (and moved) at what you wrote about her on your blog). Happy Thanksgiving. -Lee

I’m so glad you are all making it. I know you will love it. Thanks for the feedback and have a Happy Thanksgiving. Oh and be sure to post feedback after you make it.

Arlene says:

I make a very similar sweet potato casserole that is my signature Thanksgiving dish. It is devine, and can be substituted as a desert dish. Thank you for sharing your’s with me. We ate it, and of course loved it!!!!

Profile photo of Sugar Profile photo of SugarSugar says:

I’m so glad you liked it. Most people have a version of this dish and make it every year for Thanksgiving. It is the kind of thing we need to pass onto our children.

David says:

I am the exception in my family. I’m a man, and I love to cook. I learned from my mother, an amazing German woman who never really taught me, but whom I observed for years. When I got married, I became the cook in our household, and for the last 4 years I’ve become quite proficient in the kitchen and can’t attend one family get-together without everybody asking me to cook something. One of the few thanksgiving recipes I didn’t have was sweet potato casserole, so I went looking and stumbled upon this one. Thanks for sharing, I whipped this together tonight and I’ll bake it tomorrow before we head off to an early Thanksgiving party. I’m sure everyone will love it.

I’m so glad you found my site and this recipe. I promise you won’t be disappointed it is a good one. Most of the men in my family cook as well. It’s a love of food and family that I hope to inspire with my blog. Please be sure to tell your friends and family about my site too and enjoy the casserole. Oh and let me know how everyone likes it. Happy Early Thanksgiving. 😉

Pat says:

I was introduced to a very similar dish at a family dinner; this as brought by the hostess’s Southern Belle friend. She said that for years they served this in a pie shell on the dessert table until one day someone realized that if they did away with the pie shell, since sweet potatoes were technically a vegetable, it could be served WITH dinner. We’ve made it one of our staples at Thanksgiving ever since.

Profile photo of Sugar Profile photo of SugarSugar says:

Pat, I love that story. It’s funny how we have all adopted these foods to be served with a traditional Thanksgiving meal. I love when people share stories and recipes. It keeps these wonderful dishes that create lasting memories going from generation to generation. Have a wonderful holiday.

Kariann Alexander says:

Arlene, I am going to try this for the hoidays, my family loves sweet potatos, I think they are going to love your casserole. thanks for sharing. Happy Holidays, Kariann

Kariann, I can tell you every holiday this is the one dish that we very rarely have left over. Have a wonderful Thanksgiving and be sure to let me know how they liked it.
