Step 1

Slice the zucchini lengthwise into ¼-inch-thick (6 mm) strips. People debate the best way to slice the zucchini for this dish; some like to cut the slices at an angle to obtain wide ovals instead of strips. Any shape will do as long as your slices are even in thickness.

Step 2

If you are not pressed for time, let the zucchini slices dry on a baking sheet lined with paper towels for a couple of hours, so they lose some of their moisture. If you are in a hurry, go straight to frying.

Step 3

Pour about 2 inches (5 cm) of sunflower or peanut oil into a large saucepan and heat over medium heat until a deep-fry thermometer reads 350°F (180°C). (You could use a deep skillet for frying if you prefer, but I find that a saucepan helps contain the oil if it bubbles up too much.) You can test the oil by dropping a small piece of zucchini into it: if it sizzles nicely but doesn’t bubble up too wildly, the oil is ready.

Step 4

Working in batches to avoid crowding, gently place some zucchini slices into the pan, making sure that they all lie flat and do not overlap. Fry, turning once, for about 5 minutes, until deeply golden, almost brown. Transfer the slices to a tray lined with paper towels to drain and continue frying the zucchini in batches.

Step 5

Place one-third of the fried zucchini in one layer in a deep rectangular dish. Sprinkle with some of the minced garlic, herbs, and salt and season with pepper to taste. Repeat with two more layers, finishing with one last sprinkle of minced garlic, herbs, salt, and pepper.

Step 6

Cover the zucchini with the vinegar, top with the olive oil, and refrigerate for at least 5 hours, and up to 24 hours. Bring to room temperature to serve. Leftovers keep well in the fridge, covered with plastic wrap or in an airtight container, for a couple of days.
