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 crunchy, with a little salt from the pecans. So perfect. And you can enjoy the private dining in your own home!

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.

How to make Sweet Potato Casserole

Start by cooking your sweet potatoes. You can bake them in the oven (my preferred method), at 400 degrees F for an hour. Or you can peel and boil potatoes in a large pot of water (for about half an hour). The third way would be to poke them with a fork and microwave the potatoes for about 15-20 minutes. OR you can pop them in the Instant Pot!

Preheat the oven to 375 degrees F.

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.

Pour this into a 2 qt casserole dish and bake in a 375 degree oven for about 25-30 minutes.

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.
