Best tips

This is a pretty simple dish, but here’s how to put together the very best version:

Thin slices for a perfect bite: Slice your sweet potatoes thinly, as thicker slices may not cook evenly. This ensures that every layer becomes tender and infused with flavor.

Mandoline slicer precision: Invest in a mandoline slicer if you can. It simplifies the process and guarantees consistently thin sweet potato slices. This step ensures the dish and its sweet potato slices will cook evenly. There is nothing worse than having raw “spots” in your baking dish.

Dried herbs: Opt for dried over fresh herbs when seasoning your sweet potatoes. Dried herbs maintain their flavor and texture during baking, enhancing the overall dish with a herbed flavor profile.

Don't skip the broiling step: After baking, don't forget to broil for that coveted golden brown crust. It adds a great look and intensifies the flavors and crust’s crunch!

Check the doneness: Slide a sharp knife into the potatoes to check they have cooked through.

Storage instructions

To keep fresh and safe for later enjoyment, follow these storage and reheating tips:

Airtight container: Transfer any leftovers into an airtight container. Spoon leftovers into a well sealed clean, dry container to prevent moisture loss and maintain the dish's flavor.

Fridge: Store in the refrigerator for up to 3-4 days. It's best to consume them within this timeframe to ensure freshness.

Freezer: Place the leftovers in a freezer-safe container or wrap it tightly in freezer-friendly plastic wrap or aluminum foil. Ensure it's well-sealed to prevent freezer burn. Freeze for up to 60 days.

Reheating from the fridge:

Preheat your oven to 350°F (175°C).
Transfer the scalloped sweet potatoes to an oven-safe dish.
Cover the dish with aluminum foil to prevent excessive browning.
Heat for 20-30 minutes or until the center is hot.

You can reheat smaller portions in a shallow pan on the stovetop over medium heat. Heat for 5-7 minutes until the center is hot. Do not cover the pan to prevent the crusted top from softening. For best results use an oven-safe skillet to pop under the broiler for the last minute or two of reheating.

Although using the oven is best to maintain the texture of this dish, short bursts of 20-30 seconds to reheat in the microwave can work if you are in a hurry. Always gently stir leftovers in between heating when using a microwave.

Reheating from the freezer:

Preheat your oven to 350°F (175°C).
Place the frozen scalloped sweet potatoes directly into the oven.
Cover with aluminum foil.
Heat for approximately 60-75 minutes, or until the center is heated through. You may need to remove the foil in the last 10-15 minutes to brown the top.

If you prefer a faster reheating method, you can use a microwave, but this may result in a slightly different texture and less crispy top. Reheat in microwave-safe portions, checking and stirring at intervals until the desired temperature is reached.

With proper storage and reheating, your sweet potatoes will taste just as delicious as when freshly prepared, making it a convenient leftover treat.
