How to make the best roasted sweet potatoes

How long to bake a sweet potato at 450 degrees is answered in these easy-to-follow basic steps.

Step 1 – Preheat the oven

The best temperature for roasting a sweet potato is 450 F, so heat oven to 450F and place a sheet pan with parchment paper or aluminum foil on the bottom oven rack to catch any drips.

Step 2 – Prep the sweet potatoes

Before baking, it’s essential to scrub sweet potatoes thoroughly to remove any dirt or debris from their skins. Prick the whole sweet potatoes several times with a fork.

Step 3 – Bake

For a perfect baked sweet potato, place the sweet potatoes directly on the oven rack instead of using a rimmed baking sheet or baking dish. To catch any drips, place a prepared baking sheet lined with parchment paper or foil and position it on the wire rack below the sweet potatoes.

You do not need to wrap the sweet potatoes in aluminum foil because it will trap moisture, leading to soggy skin. By allowing excess moisture to escape during baking, you’ll release the natural sweetness while ensuring the skin remains crispy resulting in a perfectly baked sweet potato.

Simply rub the sweet potatoes with a little olive oil, coconut oil, or avocado oil and roast for 35-45 minutes. 

Step 4 – Serve and Enjoy

The best way to serve a baked sweet potato is to slice it open lengthwise and fluff the flesh with a fork. Then, add a pat of vegan butter and sprinkle with a pinch of kosher salt or sea salt and freshly ground black pepper for seasoning.  Enjoy it as a delicious and nutritious side dish or as a base for toppings like black beans, avocado, or salsa for a satisfying main meal.

Tips for success:

• Choose sweet potatoes that are similar in size for even cooking.
• Don’t forget to poke holes in the sweet potatoes before baking to prevent them from bursting.
• For extra crispy skin, rub the sweet potatoes with a little coconut oil or olive oil before baking.
• Experiment with different seasonings such as garlic powder or chili powder for a savory healthy side dish. If you want a little sweetness you can add cinnamon, brown sugar, or even drizzle with a little maple syrup. 
• If you’re short on time, the easiest way to save time is to cut the sweet potatoes in half and reduce the baking time to 20-25 minutes in a 450-degree oven.

FAQ’s

How long does cooked sweet potato last?

Cooked sweet potatoes can last for about 3 to 5 days when stored properly in an airtight container in the refrigerator. It’s important to let them cool completely before storing them to prevent moisture buildup, which can lead to spoilage.  If you don’t plan to consume them within that time frame, you can also freeze cooked sweet potatoes for up to 10 to 12 months.

How to store sweet potatoes

To store uncooked sweet potatoes, follow these steps:

1. Choose a cool, dark, and well-ventilated place: Sweet potatoes should be stored in a location with good air circulation, away from direct sunlight, and preferably in a cool area like a pantry or basement.
2. Do not refrigerate: Refrigeration can cause sweet potatoes to develop a hard center and an unpleasant taste. Instead, store them at room temperature.
3. Handle with care: Avoid storing sweet potatoes near onions or garlic, as they can cause each other to spoil faster.
4. Check regularly: Inspect your sweet potatoes periodically for signs of spoilage, such as soft spots, mold, or sprouting. Remove any spoiled ones immediately to prevent them from affecting the rest.

By following these guidelines, you can prolong the shelf life of your sweet potatoes and keep them fresh for longer.

2. Transfer to an airtight container: Place the cooled sweet potatoes in an airtight container or resealable plastic bag. Make sure the container is sealed tightly to prevent air from entering.
3. Refrigerate promptly: Store the container of cooked sweet potatoes in the refrigerator within two hours of cooking. Refrigeration helps slow down bacterial growth and preserves the freshness of the sweet potatoes.
4. Label and date: To keep track of storage time, label the container with the date when the sweet potatoes were cooked. This will help you know when to use them.
5. Use within 3 to 5 days: Cooked sweet potatoes can be safely stored in the refrigerator for up to 3 to 5 days. Beyond that, they may start to lose their quality and flavor.

By following these steps, you can properly store cooked sweet potatoes for meal prep and enjoy them later as leftovers in various dishes or snacks.

How to reheat a sweet potato

To reheat a sweet potato, there are several different ways:

1. Microwave: For an easy way to reheat a sweet potato, place the cooked sweet potato on a microwave-safe plate and cover it loosely with a damp paper towel. Microwave on high for 1-2 minutes per potato, or until heated through.
2. Oven: Preheat your oven to 350°F (175°C). To keep the sweet potatoes from drying out, wrap them in aluminum foil and place them on a large baking sheet. Bake for 10-15 minutes, or until heated through.
3. Toaster oven: Similar to the oven method, wrap the sweet potato in aluminum foil and place it in the toaster oven. Heat at 350°F (175°C) for 10-15 minutes, or until warmed.
4. Skillet: Cut the sweet potato into slices or 1-inch pieces and heat them in a skillet over medium heat. Add a little oil or vegan butter to prevent the sweet potato cubes from sticking and cook until heated through, stirring occasionally.
5. Air fryer: Preheat the air fryer to 350°F (175°C). Cut into slices, 1-inch cubes, or sweet potato wedges for even heating. Arrange the sweet potato pieces in a single layer in the air fryer basket to ensure they cook evenly. Cook for 5-8 minutes, remembering to shake the basket halfway through to promote even heating. Keep a close eye on the sweet potatoes to prevent them from burning. 

Whichever method you choose, make sure to check the sweet potato periodically to avoid overcooking. Once heated through, you can enjoy your reheated sweet potato as is or incorporate it into your favorite dishes like this Easy Sweet Potato Salad or this Sweet Potato Casserole.

Difference between baking a sweet potato and roasting a sweet potato

Baking and roasting sweet potatoes both involve cooking them in the oven, but they have slight differences. When you bake a sweet potato, you typically do so at a lower temperature like 350 degrees for a longer time, which helps to evenly cook the potato through. 

On the other hand, roasting involves cooking at a higher temperature like 450 degrees for a shorter period, resulting in a slightly crispier exterior while maintaining a soft interior. Both methods produce delicious sweet potatoes, but the choice between baking and roasting depends on the texture and flavor you prefer.

How long to bake a sweet potato at 350 degrees

At 350 degrees Fahrenheit, cooking a medium-sized sweet potato typically takes about 60 to 75 minutes until it’s tender and easily pierced with a fork. However, the exact cooking time can vary depending on the size and thickness of the sweet potato. It’s best to check for doneness by piercing the sweet potato with a fork or sharp knife. If it goes in easily and the potato feels soft, it’s ready to eat.

How long to bake a sweet potato at 425 degrees

At 425 degrees Fahrenheit, it usually takes about 45-60 minutes to bake a medium-sized sweet potato until it’s tender and fully cooked. Larger sweet potatoes may require a bit more time, while smaller ones might be done a bit sooner. It’s a good idea to check for doneness by piercing the sweet potato with a fork or knife. If it slides in easily and the potato feels soft all the way through, it’s ready to enjoy.

The nice thing about baked sweet potatoes is their flexibility. If necessary, you can adjust the baking time and temperature for sweet potatoes. For instance, if you’re baking other dishes at 375°F, simply add the sweet potatoes and extend the cooking time by 15 minutes. 

If you are cooking other items at 425°F the sweet potatoes will be ready approximately 15 minutes earlier. Keep in mind that the cooking duration may vary based on the size of your sweet potatoes.

How long to bake a sweet potato at 450 degrees

In a 450-degree oven baking a sweet potato typically takes about 35 to 45 minutes. The exact time can vary depending on the size and thickness of the sweet potato. It’s essential to check for doneness by piercing the sweet potato with a fork or knife. If it’s tender and easily pierced, and the skin is slightly crisp, it’s ready to be served. Keep in mind that high heat may cause the sweet potato to cook faster, so it’s essential to monitor it closely to prevent overcooking.

A cooked sweet potato is typically ready to eat when its internal temperature reaches around 210 to 215 degrees Fahrenheit. At this temperature, the sweet potato should be tender and fully cooked, making it easy to pierce with a fork or knife. Remember that the texture and readiness of the sweet potato are more important indicators than the internal temperature alone.
