How To Make This Recipe- Part I:
(Note: please see the recipe card directly below for the complete written instructions.)
- Preheat the oven to 425°F. Wrap each sweet potato tightly in foil and place on a large baking sheet.
- Bake the sweet potatoes for 1 hour- or until the potatoes are tender. Then remove potatoes from the oven (do not shut off the oven) and set aside until they’re cool enough to handle. Reduce the oven heat to 350°F.
- When ready, peel the skin off the potatoes and discard. Place the flesh into the body of a food processor, the bowl of a stand mixer fitted with the paddle attachment, or inside a large bowl to mix using a handheld electric mixer. Process/mix the sweet potatoes until just mashed- careful not to over-process/mix. This step is a good measure to remove any stringy fibers from the baked sweet potatoes.
- If you use a food processor, empty the mashed sweet potatoes into a large bowl. Then add in the brown sugar, melted butter, cinnamon, cream, vanilla extract, and maple flavor/extract. Use a rubber spatula to fold the ingredients into the mashed sweet potatoes (or mix again) until well combined and silky smooth. Set aside.
How To Make This Recipe- Part II:
- Lightly spray a large oven-safe baking vessel with cooking spray. Empty the sweet potato filling into the baking dish and use a spoon to smooth the filling until it’s edge to edge in the baking dish.
- For the pecan topping: In a medium bowl, combine the brown sugar, melted butter, pecans, flour, rolled oats, and cinnamon. Use your fingers or a fork to stir the pecan topping until well combined. Then evenly sprinkle the topping over the sweet potato filling.
- Bake the sweet potato casserole until the topping is golden and lightly toasted with bubbling edges, about 30-35 minutes.
- Serve this sweet potato casserole alongside your favorite main entrees. Enjoy!
Why Bake Sweet Potatoes Instead Of Boil?
Great question! Baking/roasting sweet potatoes allows for the potatoes to take on more flavor during the cooking process. The sugars break down and caramelize, leaving the sweet potato flesh that much richer. Oven-baked sweet potatoes are the best for this mashed sweet potato casserole, y’all! 😮💨
Can I Add Marshmallows To This?
Haha yes! If you’re a marshmallows on mashed sweet potato casserole fan, you sure can top the dish with ’em if you’d like. After step 7 in the recipe card below, sprinkle the mini marshmallows on top and broil for 30 seconds to 1 minute or until the marshmallows are lightly toasted. Alternatively, after baking the dish, you can sprinkle the mini marshmallows on top and use a handheld torch to lightly toast them as well. Yay! Are you team no marshmallows 🚫 or team heck yes marshmallows on your sweet taters 👍🏾? It’s such a hot topic, ha. Lmk!
Make-Ahead Sweet Potato Casserole
Let’s face it, holiday-specific cooking days like Thanksgiving, Christmas, or Easter can be hectic days. To save time (and precious oven space), this recipe is clutch for making/prepping ahead of time! Simply follow the steps in the recipe card, steps 1-6. After step 6, cover the sweet potato casserole dish tightly with foil. Transfer it to the fridge and it will keep for up to 2 days. Let the casserole sit out on the counter to reach room temperature. Then follow steps 7-8 to finish the dish as directed.
Storing Leftover Sweet Potato Casserole
To store in the fridge: First, make sure the leftovers have cooled down to room temperature. Transfer the remaining portion into an airtight container and keep it stored in the fridge for up to 4-5 days. To reheat casserole: Reheat the casserole in the microwave until warmed through.
Freezing unbaked casserole: Follow all steps to prepare sweet potato casserole (minus the topping), but don’t bake it. Prep the pecan topping and put it in a separate container to freeze both elements separately. Cover the casserole tightly with foil (I’d do a double layer for good measure) and keep items in the freezer for up to 2 months. Thaw overnight in the fridge, and then let it sit out for at least 2 hours on the counter until room temperature. Afterward, assemble and bake as directed until warmed through.
We all know Sweet Potato Casserole is one of the best things on the holiday table. It’s truly one of my favorite side dishes! Be sure to tag @butterbeready in your BBR recipe creations, I sure love to see it when you do. Until next time! 🤟🏾

Ingredients
For the sweet potato filling:
- 5 lbs sweet potatoes (about 6 medium-sized potatoes)
- 1 cup packed dark brown sugar
- ½ cup (1 stick) salted butter, melted

For the pecan topping:
- ½ cup packed dark brown sugar
- ½ cup (1 stick) butter, melted
- 1 cup chopped pecans
- ⅓ cup all-purpose flour

Instructions
- Place an oven rack in the center position, and then preheat the oven to 425°F. Wrap each sweet potato tightly in foil and place on a large baking sheet.
- Bake the sweet potatoes for 1 hour- or until the potatoes are tender. Then remove potatoes from the oven (do not shut off the oven) and set aside until they’re cool enough to handle. Reduce the oven heat to 350°F.
- When ready, peel the skin off the potatoes and discard. Place the flesh into the body of a food processor, the bowl of a stand mixer fitted with the paddle attachment, or inside a large bowl to mix using a handheld electric mixer. Process/mix the sweet potatoes until just mashed- careful not to over-process/mix. This step is a good measure to remove any stringy fibers from the baked sweet potatoes.
- If you use a food processor, empty the mashed sweet potatoes into a large bowl. Then add in the brown sugar, melted butter, cinnamon, cream, vanilla extract, and maple flavor/extract. Use a rubber spatula to fold the ingredients into the mashed sweet potatoes (or mix again) until well combined and silky smooth. Set aside.
- Lightly grease a large 10×10-inch baking dish (or any similarly large oven-safe baking vessel) with cooking spray and set aside. Empty the sweet potato filling into the baking dish and use a spoon to smooth the filling until it’s edge to edge in the baking dish.
- For the pecan topping: In a medium bowl, combine the brown sugar, melted butter, pecans, flour, rolled oats, and cinnamon. Use your fingers (fitted with disposable gloves, if desired) or a fork to stir the pecan topping until well combined. Then evenly sprinkle the topping over the sweet potato filling.

Notes
- Gluten-free needs? Swap the all-purpose flour for any gluten-free flour as a 1:1 ratio (we love Bob’s Red Mill gf flour!).
- Can I add marshmallows to this? Haha yes! If you’re a marshmallow on mashed sweet potato fan, you sure can top the dish with ’em if you’d like. After step 7 in the recipe card, sprinkle the mini marshmallows on top and broil for 30 seconds to 1 minute or until the marshmallows are lightly toasted.
