Trim the ends from the zucchini. Using a mandolin fitted with the julienne blade, cut the firm outer flesh lengthwise into long, spaghetti-like strands. Turn the zucchini as you work, stopping when you reach the soft, seedy center.A spiralizer, julienne peeler, or sharp knife will also work, although the size and texture of the strands will vary.
Gently cook the garlic
Heat the olive oil in a large sauté pan over medium heat. Add the garlic and cook for about 30 seconds, just until fragrant. Do not let it brown.
Saute the zucchini
Add the zucchini strands and a pinch of salt. Cook for 3 to 4 minutes, tossing frequently, until the zucchini is tender but still has some bite. Avoid overcooking, or the strands will become soft and release too much water.
Season and serve
Add the thyme and red pepper flakes, if using, and toss to combine. Taste and season with salt and freshly ground pepper.Transfer to a warmed plate or shallow bowl. Top with the hot tomato sauce and freshly grated Parmesan, then serve immediately.
Notes
Notes
Have the tomato sauce hot before cooking the zucchini; the zucchini takes only a few minutes and should be served immediately.
Use a wide skillet so the zucchini sautés rather than steams. If doubling the recipe, cook it in two batches.
Spoon the sauce over the zucchini rather than simmering them together, which can make the zucchini watery and overly soft.
Zucchini vary considerably in size. One medium zucchini should yield about 2 generous cups of strands before cooking.
