This sweet potato casserole comes together in just a few steps! Scroll to the recipe card below for complete instructions.

- Boil the sweet potatoes, then drain and mash until smooth. Add to a bowl with butter, brown sugar, chopped pecans, butter, vanilla, bourbon brown sugar, cinnamon and salt. Fold the ingredients until combined.
- Add the potato mixture to a 9″ x 13″ baking dish and top with more pecans and mini marshmallows. Bake at 375 for 25 minutes and serve.
Can You Leave Out The Bourbon In This Recipe?
Yes you can. Adding two tablespoons of bourbon to these sweet potatoes enhances the flavor, but if you don’t want to add the bourbon just omit it from the recipe. It’s still going to be an amazing sweet potato dish that everyone will rave about.

What Other Nuts Can I Use In This Sweet Potato Casserole?
Walnuts, slivered almonds and even toasted, chopped hazelnuts would be delicious. Pecans are a traditional ingredient in sweet potato casserole so we stuck with tradition for our recipe.
Also, if you’re a nut free house you can leave the nuts completely out of this recipe. The nuts add a really nice flavor and give the casserole texture, but it will still be super tasty without any nuts at all.
There’s not a person I can think of that isn’t going to want a giant scoop of these sweet potatoes on Thanksgiving, or any holiday. That perfect scoop with a little melted marshmallow…it’s so completely addicting, even if you’re plate is packed!

Can I Make This Sweet Potato Casserole Ahead Of Time?
Yes, this casserole is a wonderful make ahead recipe. You can even make it up to two days ahead of time, but we do recommend leaving off the topping and adding right before baking. Adding the nuts ahead of time will cause them to become soft, which the oven will crisp back up again, but it’s an easy step to do at the last minute.

I want to make these for a feeding ministry but I don’t think that I can peel all of those sweet potatoes. I’m sure it won’t be as good but does anyone have a guess what the equivalent in canned Yams or Sweet Potatoes would be?
Am I correct in seeing that you used Yams not actual sweet potatoes in this recipe? Yams have that bright orange color where as sweet potatoes are lighter and have more of a pale white colored inside skin? Can’t wait to make this tomorrow and wanted to be sure!
Either will work!
Good grief these were delicious! I didn’t make the full recipe and just eyeballed it. The bourbon gives it a great flavor! Thank you.
We appreciate it Stephanie – thanks so much!
I love sweet potatoes any time of the year
