Start by slicing each zucchini into slices that are about 1/4 inch thick.
Prep a large baking sheet with tin foil or parchment paper.
Spread out the sliced zucchini rounds on to the large baking sheet and don't worry too much if there is little space in between each one.
Now sprinkle your cheese evenly over each Zucchini round covering each one. I personally love the Parmesan-Romano blend and I always buy the big bag from Costco.
Bake them on 425 degrees for about 15 to 20 minutes or until the cheese turns a golden brown color. I talk to my Amazon Echo asking Alexa to set a timer and check it after about 10 minutes and keep adding 5 minute increments until it gets close to the color I want.
You can serve them with a small amount spaghetti sauce to add even more flavor too! We do that often as well.
Serve warm and Enjoy!
