Hello friends! We are nearing the end of the first week of September already and I am ready for full on fall dinners! A few of my favourites are the Chicken and Leek Pie, Beef and Potato Layered Casserole and so many more Comfort Food Recipes for Fall!

I already know that these Roasted Sweet Potatoes are going to be a favourite this cosy season. They are easy to make, very affordable, versatile and downright delicious!

What’s This Sweet Potato Dish Like

  • Difficulty – This dish is super easy and doesn’t require much more than basic cooking skills.
  • Taste – This sweet potato dish is slightly sweet with a caramelized flavour and the cornstarch adds a little bit of a crisp exterior.
  • Serving – This side dish will serve between 4 – 6 servings depending on what other dishes you are serving. It’s a perfect one to serve at Thanksgiving this year.

Ingredients

  • Sweet potatoes – Sweet potatoes are great any time of the year, but a perfect roasting vegetable for fall.
  • Seasonings – I seasoned these sweet potatoes with garlic powder, onion powder, salt and black pepper.
  • Cornstarch – By coating the sweet potatoes in cornstarch it will help give them a crisp exterior.
  • Olive oil – I drizzled olive oil over the sweet potatoes before roasting.

NOTE, The full recipe and ingredient list can be found at the end of the post in the recipe card.

Ingredients to Make Roasted Sweet Potatoes

Instructions

  1. Preheat oven – Preheat oven to 425ºF/218ºC. Have ready a large baking tray and set aside.
  2. Season sweet potatoes – Add the sweet potatoes to a large bowl. Add the garlic powder, onion powder, salt, black pepper and cornstarch. Stir really well to combine.
  3. Roast sweet potatoes – Evenly spread the sweet potatoes out over the baking tray and drizzle over the olive oil. Place in the preheated oven and roast for approximately 40 – 45 minutes. Shake the pan half way though roasting so the sweet potatoes don’t stick.
  4. Serve – Remove from oven and serve hot.

Recipe Tips

  • Cut uniformly – Make sure to cut the sweet potatoes similar sizes. This will ensure even roasting!
  • Coat completely – It’s best to add the uncooked sweet potatoes to a bowl and add all of the seasonings. This will ensure they are coated well and it’s easier than on a tray.
  • Roasting time – Mine were perfectly roasted in 45 minutes. Depending on the type of baking sheet you are using and your oven, they could cook quicker or even take a little longer.
  • Serve hot – For best results, serve these as soon as they are roasted.

Substitutions

  • Sweet potatoes – For a similar flavour you could use butternut squash or pumpkin. They taste similar and cook the same.
  • Olive oil – I love cooking with extra virgin olive oil, but vegetable oil or avocado oil will easily work for this recipe.
