How to prepare sweet potatoes for sweet potato casserole
You can use two different methods to cook your sweet potatoes:
- Stove top: Wash and peel the sweet potatoes. Cut them into cubes and place them in a large pot. Cover the sweet potatoes with water and bring it to boil over medium heat. Cook for about 15 to 20 minutes until fully cooked. Drain the water and let the sweet potatoes cool.
- Oven: Wash the sweet potatoes and pierce them several times with a fork. Rub some olive oil all over the sweet potatoes and wrap them in foil. Bake in the oven at 400F for about 30 to 40 minutes until fully cooked.
How to make sweet potato casserole with pecans and marshmallows
Start with cooking the sweet potatoes in the oven or on the stove. Then mash them really well in a food processor or with a potato masher or even a fork. If you are using anything other than a food processor, make sure the potatoes are completely smooth. That will give you the creamiest sweet potato casserole ever.
Next, added an egg and maple syrup. By now you definitely know that I’m not dogmatic about following recipes to the letter, so if you don’t have maple syrup or just feel like a substitution, I suggest using agave, brown sugar or honey. All three will work just as fine.
Now comes the fun part: Marshmallows! Now, this part is totally optional but I wouldn’t skip it. I love the flavor and the texture of melted marshmallows. Some would top the casserole with marshmallows but I just folded them into the sweet potato batter because the texture matches better. I save the top for the crunchy texture!
To top the sweet potato casserole,use brown sugar and chopped pecans, just simply sprinkling them on top. Bake the casserole for 25-30 minutes and served it warm. I assure you that this sweet potato casserole is amazingly good, whether cold or warm.
Can I make sweet potato casserole ahead of time?
Absolutely! You can make this sweet potato casserole with pecans up to three days ahead of time and simply reheat it in the oven or microwave when ready to serve.
Can I freeze sweet potato casserole?
Yes, You can easily freeze sweet potato casserole after you cook it. Simply leave the marshmallows out and store the sweet potato casserole in an airtight container.
Thaw the frozen sweet potato casserole in the fridge overnight and, when ready to bake, preheat the oven to 250 and top the sweet potato casserole with marshmallows. Then, heat in the oven for 30 minutes.
