In my family, we love this Best Sweet Potato Casserole. Sweet, salty, and topped with a crunchy streusel! You’ll love this mashed sweet potato recipe and the nutty brown sugar crunch on top!
For more holiday side dishes, don’t forget the Instant Pot Green Bean Casserole, and of course Pistachio Salad!
Ruth Chris Sweet Potato Casserole
Every family has traditions, and in most cases, you can’t shake things up. Ever.
For instance, Thanksgiving. You are either a plain sweet potato or a mini marshmallows topped sweet potato family. No middle ground exists. (of course you could also love candied sweet potatoes)
For years, my family experienced division. Depending on who hosted Thanksgiving dinner, we either had gooey, sweet marshmallow sweet potato casserole or a simpler version. The simpler casserole had just a little butter and brown sugar.
Now I serve both.
If you’ve ever been to a Ruth’s Chris restaurant you’ll recognize these potatoes!
- Sweet and creamy mashed sweet potatoes.
- Topped with a brown sugar crumble with a crunch for salty pecans.
- One of the best things about these sweet potatoes is that you can prepare them in advance. This way, you only need to bake the casserole on Thanksgiving.
Ingredients for Old Fashioned Sweet Potato Casserole
- Sweet Potatoes. Choose fresh sweet potatoes that have no root growing off them.
- Sugars. You’ll want sugar for the mashed sweet potato and brown sugar for the pecan topping.
- Vanilla extract. These candied potatoes are almost like a dessert. Using real vanilla extract (or try my homemade vanilla extract) gives even more flavor.
- Eggs. Helps the casserole fluff up to a delicious texture.
- Unsalted butter. If using salted butter, omit the extra kosher salt in the recipe.
How to Make Sweet Potato Casserole
Start by cooking your sweet potatoes.
- Bake. You can bake them in the oven (my preferred method), at 400 degrees F for an hour.
- Stove Top. Or you can peel and boil potatoes in a large pot of water (for about half an hour).
- Microwave. The third way would be to poke them with a fork and microwave the potatoes for about 15-20 minutes.
- Instant Pot. Cook them tender by using my Instant Pot Sweet Potato recipe!
Mash the sweet potatoes.
Once you cook your potatoes, combine them in a large bowl with the sugar, salt, vanilla extract, eggs, and melted butter. Using a mixer or potato masher, beat them for about 4-5 minutes until fluffy and smooth.
Bake. Pour this into a 2 qt casserole dish and bake in a 375 degree oven for about 25-30 minutes.
Sweet Potato Casserole with Pecan Topping. While the potatoes are baking, make your streusel topping. Combine brown sugar with flour, chopped pecans, and melted butter. Stir together with a fork and set aside.
After you cook the sweet potatoes, add the streusel on top. You can also add extra pecans. Then, put them back in the oven to bake for another 10 to 15 minutes. Serve hot.
Store sweet potato casserole in the refrigerator for up to 5 days.

Do you leave the skin on the potato? Making this for a friendsgiving!
No, do not leave the skin on!
Peeling can be a pain BUT of u choose to Bake them leave the skin on and when they are done the skin slips right off
Yes it does! I do not boil my potatoes any more. The flavor is so much bettet.
This is exactly what I needed to hear! The recipe doesn’t clarify that the potatoes need peeled after they’re baked and I need these kind of details in my life!
Nope, peel the potatoes.
I actúa tried them in my instant pot and so easy and fast!
Peel the potatoes.
Made this for Friendsgiving yesterday and everyone was raving about it! I also added mini marshmallows on top of the pecan streusel.
Marshmallows are the perfect addition : )
How would I freeze ahead of time?
Should I bake it all and freeze or bake sweet potatoe mixture and add strudel then freeze?
I need to know the same! Would love to freeze tonight and cook thursday
Has anybody made this with GF flour?
Yes it’s just fine with gf flour
GF flour would work great. We love using cup4cup.
Make every year with GF flour as my son has celiac. It’s his favorites side dish.
This was the best sweet potato casserole that we had tonight. Thank you for the recipe.
This sweet potato recipe was so delicious. I made this tonight and my family said they loved it.
So glad you enjoyed this meal!
I would like to make this for Christmas but make it a day or two in advance (without the topping). I can bake it Christmas day so should I freeze it unbaked or bake it and just reheat?
I was wondering how long extra I’d have to bake it for if I wanted to double the recipe?
Our Aunt Marion uses this recipe and adds a 1/2 cup of Jack Daniels Whiskey in the mix. Trust me on this…it makes the casserole taste so good! Don’t worry the alcohol cooks out but that sour mash mix gives the casserole such a nice added taste. You should try it sometime!
Sounds delicious!
Omg I added Heath toffee bits to my strudel mixture and marshmallows and it was out of this world, a thanksgiving classic is now being enjoyed as a summertime favorite!
This is a great recipe. I add coconut and raisers to the sweet potatoes. It really takes it up a notch!
This was a Easter hit. I made 2 pans and the family lived it. The topping was the game changer! Thanks for sharing it.
SO glad it was a hit with your family!
can I make this two days ahead of time? I would like to put together today for EAster
I made this last Thanksgiving for my family and I loved it. So much, that I have craved it whenever I think about sweet potatoes. I mean, I love a good sweet potato fry and that’s my first choice. But when I was grocery shopping and ran into the sweet potatoes at the store, well this was the recipe that NEEDED to be made. Its the streusel topping for sure! And I don’t mind the melted butter in the streusel – it made it a little sticky but it helps to keep that amazing top layer floating like clouds in heaven! So yesterday I paired it with a nice baked ham and again – so delicious! I even snuck some outta the pan yesterday before it was completely gone – to save for my lunch today at work. I can’t wait for lunch! It’ll be the best part of the day! Thank you so much for your amazing page of recipes!!
So happy to hear you love it too. We’ll be making it again for Easter, to go with our ham 🙂
Outstanding – I made this at thanksgiving and it was such a big hit I decided to make it for New Year’s Eve as well.
2nd time tryin’ it!
Do not melt the butter to make the streusel topping, cut it up in small pieces and using a pastry blender or fork keep working the ingredients until small tiny balls form. Then sprinkle on top of sweet potatoes, bake for about 10 more minutes or until streusel is light brown.
I can’t wait to try this. I would add raisins to the sweet potato mixture and add marshmallows to the streusel.
What type and size pan should I use?
Oh my goodness. I have gotten so many requests for this recipe! Everyone loved this more than the family sweet potato recipe. Streusel topping was not stick for me. I prebaked the sweet potatoes the day before. Added the streusel topping once the sweet potatoes were cool. Refrigerated until I was ready to pop in the oven to warm up and serve.
So happy to hear it 🙂
Ma’am, how long did you reheat?
