If you’re looking for a new spin on a classic, Pretzel Topped Sweet Potato Casserole is just the ticket. Buttery, rich potatoes topped with pecan-pretzel crumble are an irresistible creamy-crunchy combo. A sprinkle of cranberries makes this casserole even more festive.
Thanksgiving is all about comfort food, and easy Pretzel Topped Sweet Potato Casserole is about as comforting as you can get. Aside from being so good, it’s one of those sweet potato side casseroles you can prep a day or two ahead of time and bake right before you eat.
For me, holiday meals need as many make ahead dishes as possible, like make ahead mashed potatoes, it’s one less thing to worry about on the big day.
This simple sweet potato casserole only takes 30 minutes in the oven. It’s not finicky so if you need the oven at a different temperature for making your homemade yeast rolls, you can just adjust the cooking time.
The best part about this casserole is the streusel topping. You’ll have as much streusel as you do sweet potatoes! It’s quick and easy to throw together while the potatoes are cooking.
The addition of pretzels and cranberries makes it completely different from my bourbon sweet potato casserole, which has bacon in the topping. It’s slightly salty, tart and sweet all in one bite. If you want more sweet, then try a homemade marshmallow topped sweet potato casserole.
What type of sweet potato should you use for a casserole
While there are many different sweet potato varieties, I like to use the ones with dark orange or red skin, such as Red Garnet or Jewel. They are sweeter and less starchy than the ones with lighter skin.
You can store leftovers in an airtight container, but eat them within a day or two before the pretzels get soggy.

How to make this simple sweet potato casserole
Step 1 – heat the oven
Preheat the oven to 350°. However, if you need the oven at a higher temperature for other dishes, just decrease the baking time.
Step 2 – cook the potatoes
Cook the sweet potatoes until tender in the microwave or you can bake them in the oven.
Pro tip: You can cook the potatoes in one of several ways. Microwaving them is the fastest option and only takes 6-8 minutes. If you have more time you can bake them at 400° for about an hour. There’s no need to peel the potatoes beforehand, as the skins are easy to remove once they’re cooked.
Step 3 – make the topping
While the potatoes cook, make the pecan streusel by combining the pretzels, pecans, cranberries, brown sugar and melted butter. If using frozen cranberries, you don’t need to thaw them.
Step 4 – mix the base
When cooled, scoop out the flesh of the cooked potatoes with a spoon. Use a potato masher or fork to mash the potatoes until they’re smooth. If you want to get out all the lumps, use an immersion blender or ricer. Then stir in the milk, sugar, vanilla and some more butter.
Step 5 – prep for baking
Pour the sweet potato mixture into a greased casserole dish. If making this in advance, cover and store in the refrigerator until ready to bake. Sprinkle with the streusel topping right before baking.
Step 6 – bake the casserole
Bake for about 30 minutes, until the top is golden brown and the potatoes are heated through.

Pretzel Topped Sweet Potato Casserole
2 cups pretzels broken into pieces
1 cup pecans chopped
1 cup fresh/frozen cranberries
1 cup brown sugar
1 cup butter melted, divided
2½ lbs sweet potatoes cooked
5 oz. evaporated milk
¼ cup sugar
1 teaspoon vanilla
Preheat oven to 350º.
In a medium bowl, combine the pretzels, pecans, cranberries, brown sugar and ½ cup of the melted butter and stir to combine. Set aside.
In a large bowl, mash cooked sweet potatoes until smooth. (I used about 3-4 sweet potatoes) Add milk, sugar, vanilla and remaining butter. Mix until blended. (If you want your sweet potatoes to be completely smooth, then use a mixer or immersion blender or ricer.
Spoon potato mixture into a greased 2 quart baking dish. Sprinkle with pretzel mixture. Your pretzel mixture will take up about as much room as the sweet potatoes, so make sure you start with a deep enough pan. Bake, uncovered for 25-30 minutes or until the edges are bubbly.
To cook the potatoes, microwave for 3 minutes, turn and microwave for 2 more minutes depending on the size.
Barbara’s Tips + Notes
You can microwave the sweet potatoes for about 6 minutes or bake them at 400º for an hour. You can do this 3 days in advance.
If making the day before, wait to add the pretzel topping until prior to baking so the pretzels don’t get soggy.
If you need to bake this at a higher temperature, just decrease the cooking time .
