    🔪 Instructions

    Roasting sweet potatoes slices is super easy. Just peel and cut the potatoes, add the suggested seasonings, and bake!

    Preheat oven to 400 °F (200 °C).

    slice the sweet potatoes thinly.

    Make sweet potato rounds with a sharp knife or a mandoline. Make sure they have roughly the same thickness. Seson with salt and black pepper.

    mixing bowl with sweet potato slices and all seasonings.

    Place all ingredients – into a large mixing bowl, season with salt and pepper; then toss to evenly coat the slices.

    mix seasoning to evenly coat the sweet potato slices.

    Use your hands or kitchen tongs.

    turn the sweet potato baking dish to the oven.

    baking dish covered with aluminium foil.

    Time for baking sweet potatoes in foil. After placing the sweet potato slices on a large sheet pan covered with aluminum foil in the preheated oven.

    remove from the oven and remove aluminum foil.

    🍶 Substitutions

    • Fresh garlic - instead of garlic cloves, you can use garlic powder.
    • Thyme - this fantastic herb works beautifully with most root vegetables, roasted butternut squash, and pumpkin, but Rosemary and Sage are also excellent options.
    • Extra virgin olive oil - you can use coconut oil instead; however, keep in mind that it will add a coconutty flavor. if you want the sweet potato flavors to shine more, you should use a neutral oil like canola oil.

    Hint: we prefer using olive or grapeseed oil because they have high smoking points, making them ideal for baking and cooking at high temperatures while avoiding toxicity.

    📖 Variations

    • Sweeter - add two tablespoons of brown sugar or coconut sugar.
    • Spicy - add chili powder, red pepper flakes, or chipotle powder before when seasoning.
    • Crunchy - add toasted pecans.

    🍽 Equipment

    You only need a baking sheet and a mixing bowl.

    Following the exact instructions, you can also make this recipe on an air fryer, without using oil, making them compliant with a Whole Foods Plant-Based diet.

    🥡 Storage

    • Fridge – store in an airtight container for up to 3 days.
    • Freezer – we do not recommend freezing them as they will not reheat well. As the sweet potato slices are thin, they can turn mushy once reheated. If that is the case, you can always use the leftovers to make mashed sweet potatoes.

    💡 Top tip

    A few tips for baking your crispy roasted sweet potatoes evenly is slicing them evenly and using aluminum foil; this way, the exposure to heat and their texture will be optimal with a creamy inside.

    Using a large sweet potato is essential to ensure you can cut large slices. Make sure they’re all roughly the same thickness so they will cook evenly. If using smaller potatoes, reduce the cooking time accordingly. Be careful not to cut them too thin, especially if using a mandolin; if they’re almost see-through, they’re too thin!

    ❓ FAQ
