    This recipe will help you to turn a single vegetable into a perfect side dish for any occasion, whether it's a Thanksgiving dinner or a casual weeknight meal.

    Among all other side dishes I have, this one is one of my favorites. What's great is how versatile and simple this recipe is.

    You can add here some bacon bits, sprinkle them with Parmesan cheese, and even drizzle them with honey.

    Oh, and here is a quick shortcut - you can parboil the sweet potato sliced for a few minutes to speed up the roasting time.

    Main ingredients

    You will need only a few simple ingredients for this recipe. Please, see the recipe card for the ingredients quantities. 

    • Sweet potatoes: I always use Garnet or Jewel sweet potatoes for roasting. They are creamy and sweet.
    • Olive oil: you can use extra virgin olive oil, avocado oil, or a cooking spray. 
    • Salt and seasonings: I used salt, black pepper, garlic powder, onion powder, and dried oregano. Feel free to add some fresh or dried herbs such as thyme, sage, and rosemary.

    Instructions

    Roasting sweet potato slices requires only 5 simple steps.

    Step 1. Rinse and peel the sweet potato with a veggie peeler. If you decide to keep the skin on, scrub the potato well to get rid of any dirt.

    Step 2. Using a sharp knife, slice the potato into even rounds. I usually make them about ½ inch thick.

    Step 3. Place the sweet potato rounds in a large bowl and add olive oil, salt, and seasonings.

    Mix well to coat each potato slice and marinate them for about 15 minutes at room temperature or for up to 2 hours in the fridge. This will make them more flavorful.

    Step 4. Meanwhile, preheat the oven to 400°F and line a baking sheet pan with some parchment paper or aluminum foil. Arrange slices of sweet potatoes on a prepared baking sheet in a single layer. 

    Step 5. Bake in the preheated to 400°F oven for about 20-25 minutes or until the potatoes are golden brown and tender on the inside. No flipping is required. You can check if they are ready by inserting the fork in one of the rounds.
