Preheat oven to 450°F. Make sure there is a rack on the top rack spot in the oven. Align the zucchini pieces on a cookie sheet, skin down.
Mix the garlic in with the oil in a small bowl. Spoon or brush garlic oil over all of the zucchini pieces.
Place in heated oven on the top rack. Set the timer for 5 minutes and check to see if the zucchini is beginning to brown at the end of 5 minutes. If not, continue to add 2 or 3 minutes at a time until the zucchini begins to brown. Once it begins to brown, remove from oven and place in a bowl.
