Preheat oven or air fryer to 250°F. Slice eggplant into quarters lengthwise, then cut into thin strips (about ⅛ inch thick) so they resemble bacon. The thinner you slice it, the crispier it will be. A mandoline slicer works great for this.
In a small bowl, mix together the remaining ingredients. Brush the mixture generously over both sides of the eggplant slices.
If you're using an air fryer, arrange slices in a single layer and cook 10–15 minutes, until browned and dried out. If you're using an oven, lay slices in a single layer on a parchment-lined baking sheet and bake 30–45 minutes, flipping halfway, until browned and dried.
Let the eggplant bacon cool for a few minutes. It will crisp up more as it sits. The consistency is a bit drier than bacon, but you could drizzle a small amount of olive oil over it for that "greasy bacon" taste!
