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.

Instructions

- Butter– for a traditional Ruths Chris topping, you’ll want to melt the butter. If you prefer more of a crumble, just use softened butter instead.

- 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.

This has been my go-to recipe for a long time now, I make it for every holiday or potluck and it never disappoints! Thank you!
This was sooo delicious! This year is my second time making it for Thanksgiving. Tastes just like my mom used to make. So good!
Hi Aimee, I know this is last minute but hoping you have time to answer! I’ve made this several times and we love it but my question is the amount of sweet potatoes. These can range in size and relative, so what amount in pounds would you say I need for this recipe?
Lori,
I was wondering that as well but I just kind of winged it! It also put a bit less sugar.
This is delicious. A must at every Thanksgiving table!
Recipe cones out so delicious. I add finely crumbled bacon into the streusel topping. Always a hit at Thanksgiving!!
I have been making this for 3 years now. It’s a staple side dish on Thanksgiving! It’s easy to make and the brown sugar topping is better than the typical marshmallow topping! It’s delicious!
I’m giving these a 5 both for taste and ease of preparation. This is a perfect ‘Take a Long” food. because you can prepare the sweet potatoes a few days before, put the streusel topping on, and then pop them in the oven. Ours stayed super-hot and we transported them in a cooler after baking fully. The recipe doesn’t need changing a bit and its easy to increase the serving – just be sure to bake a bit longer.
Thank you so much!
Made this for one of our many huge family Christmas get together’s because my 92 year old mom’s oven was not working. I hoped it would be as good as hers. Everybody loves her sweet potato casserole and the pressure was on. Lol. This did not disappoint! My mom texted me the next day and said it was “super”. 😊 Thank you for the simple, timeless recipe! I am making it again today for my husband’s family Christmas tonight. 😋
Happy Holidays, glad you got mom’s approval 🙂
I’ve been making this for a few years now, and it’s become a staple with Holiday dinners. Delicious!!
