How to Make Dried Onion Slices

Preheat your oven to 170°F (77°C).
Thinly slice one large yellow onion (about 2 cups sliced) using a mandoline slicer or sharp knife for even thickness.
Soak the onion slices in ice water for 15 minutes to help remove excess moisture and prevent browning.
Gently pat the onion slices completely dry with paper towels.
Arrange the onion slices in a single layer on a baking sheet lined with parchment paper. Ensure they aren't overlapping.
Bake for 120-130 minutes, flipping halfway through, until golden brown and completely dehydrated. Keep a close eye on them towards the end to prevent burning.
Remove from the oven and let cool completely on a wire rack. Store in an airtight container at room temperature for up to 2 months.
