Learn how to make sturdy, tender sweet potato toast using your oven or air fryer. This guide provides step-by-step instructions for creating a quick, easy, and nutritious gluten-free and Paleo breakfast base, complete with ten versatile sweet and savory topping ideas.

Ingredients

Scale
  • 2 large sweet potatoes
  • 1 tablespoon olive oil (optional, for oven method)
  • Pinch of salt and pepper (optional)

Instructions

  1. Prepare the Sweet Potatoes: Wash and dry the sweet potatoes. Trim off the ends. Slice the sweet potatoes lengthwise into uniform planks, about 1/4 inch thick. Aim for 4 to 6 slices per potato.
  2. Choose Your Method: Decide whether to use the oven or the air fryer for toasting.
  3. Oven Method: Preheat your oven to 400°F (200°C). Lightly brush both sides of the sweet potato slices with olive oil and sprinkle with salt and pepper, if using. Arrange 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 still holding their shape.
  4. Air Fryer Method: Preheat your air fryer to 380°F (195°C). Place the slices in a single layer in the basket (work in batches if needed). Air fry for 12 to 15 minutes, flipping halfway through, until cooked through and slightly browned at the edges.
  5. Check for Doneness: The slices are ready when they are tender when pierced with a fork but firm enough to hold toppings without breaking.
  6. Serve Immediately: Place the toasted slices on a plate and add your desired sweet or savory toppings right away.

Notes

  • For the sturdiest toast, choose sweet potatoes that are medium-sized and uniform in width.
  • If your slices are too thin, they may become brittle; if they are too thick, they will take much longer to cook through.
  • You can meal prep these by toasting them fully and storing them in an airtight container in the refrigerator for up to 4 days. Reheat briefly in the toaster or oven before topping.
  • Toppings to try: Almond butter and banana slices; mashed avocado with everything bagel seasoning; smoked salmon with cream cheese; fried egg with hot sauce; cottage cheese and berries.
