Can I freeze scalloped sweet potatoes?

No, I don’t not recommend freezing the scalloped potatoes either uncooked or cooked. These are best enjoyed fresh, freezing will change the texture of the potatoes and could cause the sauce to break.

How long do I bake scalloped potatoes?

If sliced thinly and evenly, these will cook from raw in 50-60 minutes. Adjust timing as needed until desired consistency is reached.

Do you soak sweet potatoes in water before cooking?

No, you do not need to soak these potatoes before baking. When making fries it can be helpful to soak the potatoes prior to baking or frying to pull out some of the starch. But that is not needed when baking these potatoes.

Do I need to peel my potatoes for scalloped potatoes?

It is preferred to peel the sweet potatoes for these scalloped potatoes so you get a smooth, creamy texture. But you can leave unpeeled if desired.

Final Steps:

• Top with cheese and bake
• If desired, after baking, top with extra cheese and broil until golden brown

Instructions for the scalloped sweet potato recipe:

• Preheat oven to 400 degrees F, grease a baking dish and set aside. Evenly layer the sliced sweet potatoes in the dish (shown above).
• In a small saucepan heat the butter over medium-high heat. Once warm add in the garlic and shallot, sauté for 2-3 minutes until fragrant. Add in the fresh thyme, salt, and pepper. Remove from heat and stir in the heavy cream. Pour the mixture over the layered sweet potatoes. Top with half of the parmesan cheese.
• Bake for 50-60 minutes or until the sweet potatoes are tender. Once tender remove from the oven and top with the remaining parmesan cheese. Broil on high for 1-2 minutes until golden brown, watch carefully so nothing burns.
• Garnish with more fresh thyme and enjoy!

*Cover with aluminum foil is desired while baking to help keep the potatoes extra tender.

*Sweet potatoes can be easily sliced with a mandolin slicer or using a food processor if you have a slicing attachment.

*Top potatoes with a little brown sugar before baking for some sweetness.

*These scalloped potatoes heat up well as leftovers but are definitely much better eaten immediately!
