Start out by boiling the sweet potatoes until they are fork tender. Make sure they are pretty soft before you drain them, it will make mashing them a lot easier.

Once you mash the sweet potatoes, add softened butter, brown sugar, chopped pecans and a few seasonings. Mix that together and pour it into a 9″ x 13″ baking dish.

Top the sweet potato casserole with mini marshmallows and chopped or whole pecans and bake. This is one of those recipes that looks so delicious and impressive, but really takes just a few minutes to make.

Can You Leave Out The Bourbon In This Recipe?

Yes you can! Adding bourbon to these sweet potatoes just enhances the flavor a little, it’s not going to add enough alcohol to the recipe to make it off limits for the kids. But if you don’t want to add the bourbon just omit it from the recipe, it’s still going to be amazing!

What Other Nuts Can I Use In This Sweet Potato Casserole?

Walnuts, Slivered Almonds, macadamia nuts and even toasted 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 nu=ice flavor and give the casserole texture, but it will still be super tasty without any nuts at all!

    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.

    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!

    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?
