Welcome! I’m Sarah, and I’m so happy you’re here. Learn how to make perfect sweet potato toast using your oven or air fryer. This recipe provides a naturally gluten-free, grain-free base for quick, healthy breakfast ideas or satisfying snacks.

Ingredients

Scale
  • 2 large sweet potatoes
  • Cooking spray or oil for greasing (optional)

Instructions

  1. Preheat your oven to 400°F (200°C) or your air fryer to 380°F (195°C).
  2. Wash and dry the sweet potatoes thoroughly. Do not peel them.
  3. Slice the sweet potatoes lengthwise into uniform pieces, about 1/4 inch thick. Aim for 4 to 6 slices per potato. These slices will serve as your grain-free breakfast base.
  4. If using the oven: Lightly spray a baking sheet with cooking spray or line it with parchment paper. Arrange the slices in a single layer. Bake for 15 to 20 minutes, flipping halfway through, until the edges are slightly crispy and the center is tender.
  5. If using the air fryer: Lightly spray the basket. Place the slices in a single layer, working in batches if necessary. Cook for 12 to 15 minutes, shaking the basket halfway through, until tender.
  6. Remove the sweet potato toast slices from the heat. They are now ready for your favorite toppings.

Notes

  • For the crispiest texture, ensure your slices are thin and uniform.
  • If your slices are very thick, you may need to increase the cooking time by 5-10 minutes until they are fully cooked through.
  • This method works well for meal prep breakfast; store cooled slices in an airtight container in the refrigerator for up to 4 days. Reheat in the toaster or oven to crisp.
  • For a Paleo breakfast recipes base, avoid toppings containing dairy or refined sugar.
