Special occasion dinners call for Sweet Potato Casserole with Pecan Streusel! This slightly indulgent side dish is a family favorite and goes great with turkey or any protein.

Our holiday table also includes a tender Smoked Spatchcock Turkey, my mother’s Creamy Corn Casserole, the most delicious Make Ahead Creamy Mashed Potatoes, and some Chewy French Bread.

Sweet Potato Casserole

Sweet potatoes are one of our go-to potatoes. We love them in all forms – baked, boiled, and roasted. Most of the time, I prepare them in a healthful way – like in my Balsamic Glazed Brussels Sprouts and Sweet Potatoes, my Mexican Chicken and Sweet Potato Casserole, and my Sweet Potato Turkey Chili.

But there is a time for healthy sweet potatoes (360 days out of the year), and there is a time for indulgent sweet potatoes. THIS recipe is for one of those other five days out of the year when you indulge a little. Think holidays, birthdays, or other special celebratory occasions.

NOTE: This recipe has been slightly adapted since the original post. The flavor is still the same, just slightly healthier.

How to make Sweet Potato Casserole with Pecan Streusel:

Step 1
Cook the sweet potatoes. Peel and chop the sweet potatoes in large chunks. Add to a stock pot and cover with water. Bring potatoes to a boil over medium-high heat and add a few pinches of salt.

Step 2
Mash the potatoes. Drain the potatoes and add them back to the pot. Heat for a few minutes to help evaporate the excess liquid. Then use a potato masher and mash until creamy.

Step 3
Add the potato mash ingredients. Add the butter, eggs, half and half, brown sugar, and salt (if needed). Mash again.

Step 4
Pour the mixture into a casserole dish. Pour the sweet potato mash into an 8×8 casserole dish. Smooth evenly to all edges of the dish.

Step 5
Mix up the pecan crumble topping. Combine the pecans, brown sugar, flour, and cinnamon. Then pour the melted butter over the top and stir well.

Step 6
Pour the crumble topping on top of the sweet potato casserole. Spread it evenly over the top of the potatoes.

Step 7
Bake the casserole. Bake the sweet potato casserole for about 35-40 minutes on 350 degrees.

How to prep Sweet Potato Casserole in advance:

  1. Prepare the sweet potato mash and place in casserole dish. Cover and store in the refrigerator.
  2. Prepare the crumble in a separate bowl – except the melted butter. Keep covered on the counter.
  3. When ready to bake, melt the butter and add to the crumble. Spread over the sweet potatoes and bake.

While this Sweet Potato Casserole serves about eight people, you just might want to double it for big eaters or for a large party. Leftovers are really delicious as well!

Sweet Potatoes are healthy!

  • Thanks to their many health benefits, sweet potatoes are considered a superfood. They’re loaded with beta carotene, functioning as a potent antioxidant.
  • Sweet Potatoes have over 400% of your daily needs for vitamin A in one medium spud, as well as loads of fiber and potassium.
  • They have more grams of natural sugars than regular potatoes, but more overall nutrients with fewer calories.

We eat sweet potatoes almost every week, in one form or another. It’s good to shake it up and try new ways to prepare this super spud.
