Learn how to make sweet potato toast as a quick, healthy, and gluten-free alternative to bread. This guide covers slicing, cooking methods (oven and air fryer), and offers both savory and sweet topping ideas.

Ingredients

Scale
  • 2 medium sweet potatoes
  • 1 tablespoon olive oil (optional, for oven method)
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 400°F (200°C) or set your air fryer to 380°F (195°C).
  2. Wash the sweet potatoes well. 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.
  4. If using the oven, lightly brush both sides of the slices with olive oil and sprinkle with salt and pepper.
  5. Oven Method: Arrange the slices in a single layer on a baking sheet lined with parchment paper. Bake for 15 to 20 minutes, flipping halfway through, until tender but firm.
  6. Air Fryer Method: Place the slices in a single layer in the air fryer basket (you may need to work in batches). Cook for 10 to 15 minutes, shaking the basket halfway through, until golden brown and slightly crispy.
  7. Remove the sweet potato toast slices from the heat. If they are not firm enough, return them to the oven or air fryer for a few more minutes.
  8. Top immediately with your choice of savory or sweet toppings.

Notes

  • For the crispiest toast, ensure your slices are uniform in thickness. Thicker slices will require longer cooking times.
  • You can meal prep the cooked sweet potato toast slices and store them in the refrigerator for up to 4 days. Reheat them in the toaster or oven before topping.
  • Try savory toppings like avocado, a fried egg, hummus, or smoked salmon.
  • For sweet options, use almond butter, sliced banana, cinnamon, or a drizzle of maple syrup.
