How to Store / Freeze This Dish
- Allow the sweet potatoes to cool completely before storing. This prevents condensation, which can make them soggy.
- Transfer the cooled sweet potatoes to an airtight container. This helps maintain their texture and flavor.
- Store the container in the refrigerator. They will keep well for up to 4-5 days.
- For longer storage, consider freezing. Place the sweet potatoes in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
- Once frozen, transfer the sweet potatoes to a freezer-safe bag or container. Label with the date for easy tracking.
- When ready to use, reheat the sweet potatoes in the oven at 375°F (190°C) until warmed through, about 10-15 minutes. This helps retain their crispy texture.
- Alternatively, you can reheat in the microwave, though they may lose some crispiness. Use a microwave-safe dish and cover loosely to avoid drying out.
How to Reheat Leftovers
- Preheat your oven to 375°F (190°C). Spread the leftover sweet potatoes on a baking sheet and cover with aluminum foil to prevent them from drying out. Bake for about 10-15 minutes or until heated through.
- For a quicker option, use a microwave. Place the sweet potatoes in a microwave-safe dish, cover with a damp paper towel, and heat on high for 1-2 minutes, stirring halfway through to ensure even heating.
- If you prefer a crispy texture, reheat in a skillet. Heat a small amount of olive oil in a skillet over medium heat. Add the sweet potatoes and cook, stirring occasionally, until they are heated through and slightly crispy, about 5-7 minutes.
- For an air fryer, preheat to 350°F (175°C). Place the sweet potatoes in the basket in a single layer and cook for 3-5 minutes, shaking the basket halfway through to ensure even heating.
