Ingredients You’ll Need for a Sweet Potato Casserole with Crumb Topping
- Red Garnet sweet potatoes – red garnet are the ones you see most commonly at the grocery with a bright orange flesh.

- Bacon – just two slices but it adds a smokey flavor, if you can find pepper bacon, it’s even better.
- Pecans – these are in the streusel and add a nice crunch to the mashed sweet potatoes.
- Cayenne pepper – just a pinch gives the topping a little heat.
- Pantry items -brown sugar, flour, butter, milk, eggs, vanilla and cinnamon.
Pro Tip: Save time when making sweet potato casseroles and cook the sweet potatoes in the microwave.
It’s So Simple to Make a Sweet Potato Casserole with Streusel
Step 1: cook the potatoes
Cook the potatoes. You have two choices, you can either bake them for about 1 hour, or microwave the potatoes for about eight minutes.
Step 2: make the filling
Once cooked, peel off the skins and mash with a potato masher. If you don’t have one, use a fork. Add milk, butter, eggs, bourbon and the rest of the seasonings and combine. Pour into a baking dish.



Step 3: make a crumble
Make the topping by combining all the ingredients and then sprinkle on top of the sweet potatoes. At this point you can cover and refrigerate overnight or until ready to bake.


It needs to bake for about 30 minutes until the top is golden brown.

Try this streusel topped sweet potato casserole for Thanksgiving, it will really spice up the more traditional side dishes. If you don’t like bourbon, you can substitute vanilla. I personally prefer the bourbon flavor, but these are amazing both ways.
You can make this in advance and add the topping before baking. Once baked, it will only save for a day or two before the topping looses its crunch. Still delicious, but a little mushy.

- This will last for 1-2 days and then the topping will get mushy.

Kim says
Would this be fine to make night before at home and then take to a potluck the next day and just reheat in oven?
Barbara Curry says
Yes, it will reheat great in the oven, let it come to room temperature before you put it in the oven. If you need to reheat in a microwave, the pecan topping will not be as crisp but will still taste great. Hope it’s a hit at your potluck.
