Why this Recipe is Best

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. There is no middle ground.

For years, my family was divided. Depending on who hosted Thanksgiving dinner, we either were served gooey, sweet marshmallow sweet potato casserole….or a sweet potato casserole with a little butter and brown sugar.

Those were the only choices. Until now.

Now I host Thanksgiving myself, and it’s my turn to determine how I want to serve my sweet potatoes. And while I love marshmallow topped, and brown sugar…today’s streusel topped sweet potato casserole are hands down, my favorite.

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 have them prepped ahead of time so that you only need to bake them on Thanksgiving. 

Ingredient Notes

Ingredients needed for sweet potato casserole with pecan topping.

Sweet Potatoes. Choose fresh sweet potatoes that have no root growing off of 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

Step by step photos showing 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. OR you can pop them in the Instant Pot! Cook them tender by using my Instant Pot Sweet Potato recipe!

Mash the sweet potatoes.

Once your potatoes are cooked, combine them in a large bowl with the sugar, salt, vanilla extract, eggs, and melted butter. Using a mixer, 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.

Make the 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.

Once your sweet potatoes have cooked, top with streusel (and extra pecans on top if desired) and return to the oven to bake an additional 10-15 minutes. Serve hot.

Making ahead of time

There is nothing worse than trying to figure out what goes in the oven, and when. Fortunately, this sweet potato casserole gets it’s “BEST” rating because of the flexibility. 

First, you could bake as written above, if oven space is not an issue.

Or, you could bake the 25 minutes, top with the streusel and refrigerate until the next day. Then you would only need to pop it back into the oven for about 20 minutes.

You could also bake it as directed for entirety and allow to sit on the table for about 30 minutes (covered with foil to keep hot). This gives you time and space to warm up some dinner rolls and get the rest of your food heated and ready.

Comments & Reviews

  1. 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?

  2. 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!

  3. 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!

  4. This is a great recipe. I add coconut and raisers to the sweet potatoes. It really takes it up a notch!

  5. This was a Easter hit. I made 2 pans and the family lived it. The topping was the game changer! Thanks for sharing it.

  6. 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!!

  7. 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.

  8. 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.

  9. My cousin made this for Thanksgiving and it was a fan favorite. I couldn’t get enough. I just got back from the grocery store with the ingredients so I can make it today!

  10. Hi! I think there is a typo in your recipe – is the butter for the streusel actually meant to be melted? My streusel came out sticky as others have commented, and I think cold butter may have worked better. Thanks!

  11. This was a huge hit today for Thanksgiving dinner! I added half a teaspoon of vanilla and sprinkled some cinnamon into the streusel mixture and it was to die for!
