Our favorite way to cook and eat eggplant is a delicious, and easy, roasted eggplant "chips" recipe. The whole family will enjoy these "chips" as a snack. With just three ingredients, they bake in the oven and are ready in about 15 minutes.
Preheat oven to 400 degrees F on convection. Spray two baking sheets with a light coating of the olive oil spray.
Wash, dry, and trim each eggplant then thinly slice into pieces ¼" thick. Alternatively, use a mandoline slicer if you have one.
Place eggplant rounds on the baking sheets in one even layer. Spray the tops with another light coating of olive oil.
Put both baking sheets in the oven together (one on a rack above the other) and cook until the first few pieces begin to turn brown, about 8 to 10 minutes. Remove the pieces that are starting to brown and put the remaining pieces back in the oven for another 30 seconds to a minute.
At this point in the baking process I basically just stand at the stove, keep taking each baking sheet out (as the other still cooks), remove the brown pieces, keep cooking the rest, and repeat until they are all done. If you have a mandoline for more uniform slices, they'll have a better chance of all being ready at the same time, but even with a steady hand mine are always ready in batches.
The outcome is not as crispy as a deep-fried chip, but still quite tasty. Season with salt and pepper and serve.
