Add sliced zucchini to boiling water. Boil for 4-5 minutes, you want the zucchini to be soft enough to smash but not mushy.
Add zucchini to a sheet pan lined with parchment paper. Using the bottom of a jar or glass smash each piece of zucchini. After you have smashed the zucchini use a paper towel or cloth to absorb the water that has been release from the zucchini.
Coat zucchini in oil, yeast, garlic powder, salt and pepper. Bake for 30-40 minutes until zucchini pieces are crisp.*
Let zucchini cool for 5-10 minutes. The zucchini will crisp up more as it sits. Dig in and enjoy!
Notes
*If you notice some zucchini pieces are starting to brown and crisp before others take them out of the oven and let the others continue to cook. This can happen if your zucchini is uneven in size.
