Recipe Ingredients
Here’s an overview of the simple ingredients we’re using. Jump to the recipe card below for exact ingredient amounts and printable instructions.
- Potatoes: I use sweet potatoes which I peel and slice into ½-inch thick slices using a mandoline slicer. Make sure to cut the sweet potato into similar size slices so it cooks evenly.
- Cream: Heavy cream is added to this dish, you could use light cream, but it won’t have the same creamy consistency. You could sub in whole milk or coconut milk.
- Sugar: Light brown sugar is sprinkled over the top of the potatoes, it has a great molasses flavor. If looking for substitutes, a drizzle of honey or maple syrup would be good alternatives.
- Spices: I spice the dish with a combination of ground cinnamon and ground cloves. You could also use ground nutmeg.
- Nuts: Chopped pecans are sprinkled over the top of the potatoes. You could also use chopped walnuts or almonds.
- Marshmallows: Just before the end of the cook I sprinkle over mini marshmallow and broil them for a couple of minutes. This adds great sticky sweetness to the dish.
How to Make a Sweet Potato Casserole
Start by preheating the oven to 350 degrees Fahrenheit and spray a 9×13-inch baking dish with non-stick spray.
Step 1: Prepare Sweet Potatoes: Peel and slice the sweet potatoes into 1/2-inch thick slices. Then place the sliced sweet potatoes into the casserole dish and drizzle the heavy cream over the top evenly for a creamy sauce.
Step 2: Flavor the Sweet Potatoes: Now sprinkle the brown sugar around on top then put the slices of butter between the sliced potatoes.
Add some warming spices by sprinkling the cinnamon and cloves on top of the potatoes.
Step 3: Add Pecans: Add the pecans to the sweet potatoes.
Step 4: Bake Sweet Potatoes: Place the casserole dish into the hot oven and bake for 55-65 minutes, or until the potatoes are tender and cooked through.
Halfway through the cook, drizzle some of the sauce around on top of the potatoes so that the tops are fully cooked as well. Once baked, remove the casserole dish from the oven.
Set the oven to broil then sprinkle the marshmallows on top of the potatoes and broil for 1-2 minutes or until the marshmallows are light and golden. Keep an eye on the potatoes during this process being careful not to burn the marshmallows.

DO SWEET POTATOES NEED PARBOILING BEFORE ROASTING?
No, you don’t need to par boil the sweet potatoes before roasting them in this dish. They are cooked in a hot oven until tender.
RECIPE TIPS & MODIFICATIONS
- USE A SHARP KNIFE TO SLICE THE POTATOES, this will help you get even sized slices of potato. If you have a handheld mandolin, this is perfect for getting even slices of potato.
- TAKE CARE WITH THE SPICE of this dish and don’t be too heavy handed. Ground cloves have a strong flavor that can overpower, so only use the quantities suggested.
- DON’T WALK AWAY FROM THE BROILER when browning the marshmallows, otherwise you risk the marshmallows burning and becoming bitter.
Storage Tips
- Once cooked and cooled, these scalloped sweet potatoes can be stored in an airtight container in the refrigerator for up to 4 days.
- I don’t recommend freezing this dish as neither sweet potatoes nor heavy cream freeze well.
