Tips and Tricks
Cut Evenly - Keep the sweet potato cubes close to ¾ inch so they cook at about the same rate. Smaller pieces may brown too quickly.Avoid Crowding - Use two baking sheets if necessary. Crowded potatoes tend to steam instead of developing caramelized edges.Watch the Maple Syrup - Maple syrup can darken quickly at high temperatures. Check the sweet potatoes during the last few minutes to prevent burning.Prepare Ahead - Peel and cube the sweet potatoes up to 24 hours in advance. Store them submerged in cold water in the refrigerator, then drain and dry thoroughly before seasoning.
Storing and Reheating
Refrigerator - Store leftover roasted sweet potatoes in an airtight container in the refrigerator for up to 4 days.Freezer - Freeze cooled sweet potatoes in a freezer-safe container for up to 3 months. They may be softer after thawing.Oven - Spread leftovers on a baking sheet and reheat at 375°F for 10 to 15 minutes, or until heated through.Air Fryer - Reheat at 350°F for 3 to 5 minutes, checking frequently to prevent the maple coating from burning.Microwave - Heat in 30-second intervals until warmed through. The sweet potatoes will be softer than when freshly roasted.
