Pre-heat the oven to 450 degrees F (Fan forced oven) . Keep the tray at upper one third of the oven.
Clean and pat dry Zucchini. Cut ½ inch round slices. If the rounds are too big, cut each slice into half.
In a bowl toss Zucchini slices with olive oil.
Add lemon pepper seasoning and ½ cup finely grated Parmesan cheese(reserve remaining cheese to use later). Toss everything well.
In a large baking sheet arrange the zucchini slices spaced little apart. Don't over crowd the pan. Divide into 2 sheets if required.
Sprinkle rest of the grated parmesan on top.
Bake for 5 minutes. Then broil for 2-3 minutes more or until you see small brown spots on the zucchini slices.
Zucchini slices would be just cooked through yet will have a bite to it.
Keeping the skin on adds texture, so keep them on.
Instead of baking, we are roasting the zucchini. Baking at high-temperature zucchini will get roasted on the outside yet doesn't get fully cooked through. You would also prevent it from becoming soggy.
Pre-grated bottled parmesan will also work in this recipe. But freshly grated parmesan has a better flavor on any day.
