Preheat oven to 425°. Line a baking sheet with parchment paper and lightly mist the top of the paper with oil spray. Set aside.

Make a shallow slice in each plantain on two sides so you cut through the skin.

Microwave plantains (in skin) until they’re soft in the center, about 6 minutes, depending on your microwave. The skin will turn black.

Peel plantains and cut into slices about ¾ inches thick while hot. You should get about 12 slices per plantain.

Flatten plantain slices using something flat and heavy (like the bottom of a glass). The plantains should be soft enough to crush but firm enough to hold their shape (a small disc).

Place flattened plantains on the prepared baking sheet. Mist the tops with oil spray and sprinkle with salt. Place in the oven and bake until golden on the bottom, about 10 to 12 minutes. Flip the plantains over, mist the tops again with oil spray, sprinkle on additional salt and bake until golden and crispy, about 8 more minutes.
