Preheat your oven to 400°F (200°C).
Place the sweet potato slices in a large bowl. Add the olive oil, garlic powder, onion powder, smoked paprika, and sea salt. Toss until the slices are evenly coated with the seasoning.
Arrange the sweet potato slices in a single layer on a baking sheet lined with parchment paper. Ensure that the slices are not overlapping to promote even crisping.
Bake for 20-25 minutes, flipping halfway through, until the sweet potatoes are tender and crispy around the edges. The baking time may vary slightly depending on your oven and the thickness of the slices.
Remove from the oven and let cool slightly. Top with your choice of AIP-compliant toppings.
Enjoy your crispy, seasoned sweet potato toasts warm.
