Warm the oil in a large skillet set over medium heat. Add the garlic and cook for about 30-60 seconds, or until fragrant.
Increase the heat to medium-high and add the zucchini noodles. Cook for about 2 minutes, constantly tossing gently with kitchen tongs, until the water releases from the zucchini and it begins to feel tender.
Remove the pan from the heat and transfer the noodles to a fine mesh strainer to drain off as much of the water as possible. Season with salt, pepper, and red pepper flakes, to taste. Serve garnished with Parmesan cheese and crushed red pepper.
Notes
Cook fast on high heat with oil, do not cover pan. Add salt after removed from heat.
