Variations for Southern Sweet Potato Casserole

Make it healthy– Use honey or maple syrup instead of sugar to sweeten this casserole. Use almond milk or coconut milk instead of whole milk or half and half. Also, replace butter with coconut oil. Omit the marshmallows and replace that with a healthy crumbly pecan oat topping.

Savory sweet potato casserole– You can mix in some finely chopped fresh Italian herbs such as basil, parsley, chives, sage, oregano as well as garlic powder or even fresh roasted garlic.

Other topping options– Such as crunchy toppings like nuts and brown sugar, streusel topping, or even just nuts

Try other nuts– Such as walnuts, cashews, peanuts, almonds, or even pistachios.

Add bourbon– Add 2 Tbsp bourbon for additional flavor. The alcohol will cook off so it is fine for kids to eat.

Tips And Techniques

Are yams and sweet potatoes the same thing? No, they are not the same. They are actually different root vegetables. Yams are more akin to yucca as far as flavor and texture go.

Are there eggs in sweet potato casserole? No, they are not needed in this recipe. The sweet potatoes have enough starch in them that there is no need for a binder like eggs.

Why is my casserole runny? How to fix a runny watery casserole? This happens if you boil the potatoes before adding them to the casserole, or if there is too much liquid added. Use uncooked potatoes for this recipe, and if there is too much liquid, you can continue cooking the casserole till the liquid evaporates, but be careful not to overcook. Another option is add more potatoes. The starch in the potatoes will help absorb the liquid.

Why is my casserole dry? How to fix a dry casserole? There is not enough liquid in the casserole. Simply mix in more half and and half until it is the texture and consistency you are looking for.

How do I make a toasted topping? If you prefer a toasted marshmallow topping, sprinkle marshmallows and pecans on top of the mashed sweet potatoes. Don’t cover with lid! Transfer crockpot to the oven and broil for 3-5 minutes or until marshmallows are golden brown.

Adjust the sweetness– Add more or less according to your preference of sweetness. You can replace with honey or maple syrup.

What kind of milk to use? Use half and half or a combination of whole milk and heavy cream. I don’t recommend using fat free milk or 2% milk because it doesn’t make this casserole as creamy as I would like.

Adjust seasoning– Add more or less of cinnamon, pumpkin pie spice, vanilla.

Storage

Refrigerate– In a sealed container for up to 3 days.

Freeze– I do not recommend freezing this because the marshmallows and pecans will not thaw well.

Reheat– In the microwave.
