Halve the zucchini lengthwise and score the flesh in a crosshatch pattern so that the salt can penetrate it.

“Rain” or “snow” salt onto the scored side of the zucchini from a height that allows it to evenly distribute. Leave the zucchini for 10–15 minutes so that salt has time to draw out moisture, which will help maintain the density of the vegetable as it cooks. Pat the zucchini dry.

Preheat oven to 450°F.

Heat canola oil (use just enough to coat the bottom of the pan) in a 12-inch fry pan until it’s shimmering and just beginning to smoke.

Add the zucchini flesh side down in the oil, adjust the heat to allow the zucchini to sear and caramelize without burning.

Cook about 5 minutes, then add herbs or garlic and immediately place the pan in a 450°F oven to roast for 25–30 minutes or until the zucchini are completely soft (make sure to use an oven-safe pan to avoid transferring the zucchini to a separate baking sheet).

Transfer zucchini to paper towel–lined plate to blot excess oil.

Arrange the zucchini on a serving platter. Then spoon the vierge sauce over the top.

For the sauce : While the zucchini is roasting, gently combine all the sauce ingredients in a mixing bowl, and allow the flavors to blend together. The vierge sauce may be prepared up to a day in advance and stored in the refrigerator. If you refrigerate, allow the vierge to come to room temperature before serving so that the flavors unfold and the olive oil is not congealed.

Arrange the zucchini on a serving platter. Then spoon the vierge sauce over the top, following by a sprinkling of finishing salt.
