I’ve been making renditions of Bourbon Sweet Potato Casserole for years around the holidays. It might be my favorite Thanksgiving side dish, thanks in part to my love of bourbon, sweet potatoes and casseroles that veer toward sweet. (But not too sweet.)

This recipe was developed because I wanted to make a traditional sweet potato casserole using less sugar since sweet potatoes are naturally pretty sweet.

So you’ll see this recipe calls for maple syrup mixing with the sweet potatoes and just a scant ¼ cup of brown sugar for the crunchy pecan topping.

Gone are the days of excessively sweetened sweet potato casserole! And this recipe has been a crowdpleaser ever since.

    In addition to these tools, you’re also going to need the following ingredients:

    • Sweet potatoes! 4.5 lbs. of ’em.
    • Pure maple syrup—not the stuff in a bottle that’s an imitation. They add such a lovely natural sweetness that compliments the sweetness of the sweet potatoes.
    • Bourbon
    • Egg
    • Salt
    • Ground cinnamon—because this adds such lovely warmth.
    • All-purpose flour—I prefer unbleached, but you can use the regular kind if that’s what you’ve got on hand
    • Rolled oats—not the instant variety because their texture won’t hold up
    • Light brown sugar
    • Pecans—these add such a lovely crunch and nuttiness to the topping!
    • Unsalted butter

    How do you make Sweet Potato Casserole?

    First and foremost, cook your sweet potatoes!

    How to cook sweet potatoes

    I’m partial to baking them in the oven at 400°F for about an hour if I’ve got the time earlier in the day that I’m making the casserole. Use a fork to poke through the skin a few times before baking so they don’t explode in the oven. When they’re done, you want them to be nice and tender, then let ’em cool completely.

    You can also boil them or cook them in the microwave them, too.

    Make the Sweet Potato Casserole

    Preheat the oven. Spray a 1.9 qt. (or larger) casserole dish with nonstick cooking spray, and set it aside.

    Scoop the sweet potato flesh into a large bowl. Measure in the maple syrup, bourbon, egg, salt and cinnamon

    Use a hand mixer to blend the ingredients until smooth. This might take a few moments because the sweet potatoes can sometimes be a little chunky.

    Blend the ingredients together using a hand mixer, mixing until smooth.

    Scoop the sweet potato casserole filling into your prepared baking dish. Set it aside.

    Make the Oat Pecan Streusel Topping

    Make sure your pecans are actually chopped. If they aren’t, it will be a little more challenging to get a consistent crumb to this topping.

    In a medium-sized mixing bowl, measure out the flour, oats, brown sugar and pecans. Use a fork to mix them until combined.

    Slice the chilled butter into small pieces, then cut it into the streusel topping with a pastry cutter or a fork. You basically want the topping to resemble the texture of wet sand.

    Sprinkle the streusel topping onto the sweet potato filling already in the pan.

    If you are making your casserole in advance, this is the part where you’ll stop. Wrap the casserole in plastic wrap, and store it in the fridge for up to 3 days before doing the final bake before you serve guests.

    Bake the Casserole

    Transfer the casserole dish into the preheated oven.

    Bake for 40 minutes, or until the streusel topping is browned and crispy. Keep an eye on it as it bakes because I’ve had mine burn because I haven’t been paying close attention.

    When the topping is ready, remove the dish from the oven, and serve warm.

    Erin’s Easy Entertaining Tips

    If you’re hosting Thanksgiving, Friendsgiving, Christmas or any other holiday meal, I implore you to make this bourbon sweet potato casserole!

    Not only is it delicious and a crowd pleaser, but you can make it in advance to ensure you’re not frantically cooking as guests are about to arrive.

    Here are some of my easy entertaining tips that you can use whole making this homemade sweet potato casserole:

    • Put together the casserole early. That means, bake the sweet potatoes and let ’em cool. Make the sweet potato casserole filling. Make the streusel topping, and sprinkle that on top of the filling. Store it all in the fridge until you want to bake it for guests.
    • Similarly, you can put this together in pieces! I’ve made this casserole where one day, I baked the sweet potatoes, then stored those in the fridge. The next day, I put together the casserole, then stored it in the fridge again. And then the following day, I baked and served it.

    Frequently Asked Questions

    Are yams and sweet potatoes the same thing?

    Technically, no, they are not the same type of vegetable. Yams have a more textured skin and their flesh has a similar texture to that of yucca instead of a white potato.

    However, in American supermarkets, they are traditionally marketed as the same, thanks to Louisiana sweet potato growers in the ’30s calling theirs “yams” so they’d be different.

    Is sweet potato casserole healthy?

    I don’t know if I’d call this casserole a health food, but it certainly could be less healthy.

    This particular Bourbon Sweet Potato Casserole recipe calls for maple syrup instead of granulated sugar, and it also has some oats and pecans.

    Is it better to boil or bake sweet potatoes?

    I don’t think there’s a better way to make sweet potatoes, and in this recipe, I’ve discussed cooking yours in the oven, boiling and microwaving them.

    How do you thicken up sweet potato casserole?

    The sweet potatoes are already pretty luxurious and creamy, and the egg helps fortify them in this recipe, too.

    How long can sweet potato casserole sit out?

    Up to 2 hours, though I really recommend getting it off the table and back into the fridge by that point.

    What type of bourbon should I use in this casserole?

    We don’t have a typical specific brand that we use in this recipe, but I do recommend staying away from bourbons that are blends (and bottom shelf bottles.) You’ll get hints of the taste of bourbon throughout this casserole, so you want it to be GOOD. But, like, not Pappy Van Winkle good. 😉

    Can my kids eat this bourbon sweet potato casserole?

    Short answer: Yes, they can.

    Long answer: While the bourbon cooks out of the sweet potatoes as this casserole bakes, it won’t be completely gone. (So yes, there is lingering alcohol… but not a ton.) There are 2 oz. in this entire casserole dish, which feeds 8-10 people.

    If you’re concerned about your children eating this dish, just omit the bourbon. The casserole will still taste delicious, even if it doesn’t have the lingering bourbon flavors.

    Quick tips and tricks for the best Sweet Potato Casserole

    • Put it together early. I’ve found when I rush this dish, the sweet potatoes take particularly long to cook, and I get antsy and then burn my fingers trying to mash them. If you make this a day or two before you plan to consume it, you won’t have to worry about burning your fingers in order to get it onto the table in time.
    • Bake it an hour before you’re going to serve it. This means pulling it out of the fridge and popping it into the hot oven and serving shortly afterward.
    • Swap out the nuts! Walnuts would be lovely in this dish, too, if you have those on hand.

    1. Hello!

      I was wondering if you could make this ahead of time and bake the day of? I have to work the morning before it and would be best if I was able to do this in parts, any suggestions?

      Thanks,
      Susanna

      1. Hey there, Susanna. I think you could absolutely make the sweet potato portion of this casserole beforehand! (So, bake the sweet potatoes, scoop them out and mix them with the filling ingredients. When they’re done, put them in your casserole dish, and cover with plastic wrap before popping in the fridge overnight.) Unfortunately, the streusel topping doesn’t last well in the fridge, so hold off on that until the morning (or afternoon) of, and then pop the casserole in the oven after the streusel is made!

    2. I would have eaten this off the page if it were only possible. It looks mouthwateringly delicious. Is it crunchy on the top? It looks it.

    3. I love sweet potatoes so much it’s just sad. We eat ours with all the brown sugar and butter—and it’s plenty sweet too. This looks like a great way to enjoy what we love without the coma afterward. 🙂

    4. I am always looking for ways to jazz up the classic holiday side dishes! This bourbon sweet potato casserole sounds incredible!

    5. I agree with you. This type of casserole is always my fave thing at the table! Yours looks GREAT!
