This is by far my favorite way to have zucchini. I feel like squash and zucchini often get mushy when you cook them. Grilled zucchini is crisp and has a slightly carmelized flavor. They key is to make your zucchini slices an even thickness so they cook evenly. Thinner slices are crisper, but burn more easily. Thicker slices are a little more forgiving. Start by heating up your grill to a pretty high temperature. Slice your zucchini while you’re waiting for the grill to heat.
Trim the top and bottom off your zucchini. If you’re cutting the zucchini with a knife, start by cutting a thin slice down one edge. Now you can put that flat edge face down on your cutting board and it is somewhat easier to cut the rest of your slices without having your zucchini roll around.
I am not great at cutting straight, so I like to use a mandoline slicer. (I highly recommend getting a mandoline slicer if you don’t own one already. You can use it to make even slices of all kinds of vegetables. McGuckin has a good selection of inexpensive mandoline slicers.)
Put the zucchini in a bowl with olive oil, salt, and pepper. Stir until the zucchini slices are thoroughly coated.
Grill for about 5 minutes on the first side–until there are nice grill marks. Turn the zucchini only once. It will take about half as long to cook the second side. The zucchini is great served straight off the grill. You can also sprinkle it with a little bit of grated Parmesan. Or you can dip it in my favorite secret guilty pleasure–ranch dressing.
