Make this silky 7-ingredient zucchini pasta sauce in just 30 minutes! Fresh zucchini, garlic, lemon, and Parmesan create a light, creamy summer pasta sauce the whole family will love.
Bring a large pot of generously salted water to a boil. Cook the spaghetti al dente. Before draining, scoop out at least ½ cup of starchy pasta water and set it aside.
Grate the zucchini on the large holes of a box grater. Squeeze out as much liquid as possible using your hands or a clean kitchen towel.
Heat the olive oil in a large skillet over medium heat. Add the minced garlic and cook for 1-2 minutes until golden and fragrant. Watch it closely - it goes from golden to burnt fast.
Add the squeezed zucchini to the skillet. Season with salt, pepper, and red pepper flakes. Cook, stirring occasionally, for 10-12 minutes until very soft, golden at the edges, and almost creamy-looking.
Add the drained pasta to the skillet. Pour in the reserved pasta water a splash at a time, tossing everything together. Add the Parmesan, lemon zest, and lemon juice. Keep tossing until the sauce looks glossy and coats every strand.
Remove from heat. Fold in the torn basil. Taste and adjust seasoning. Serve immediately with extra Parmesan and a drizzle of olive oil.
Notes
Squeezing moisture from the zucchini is the most important step - skip it and your sauce turns watery instead of silky. Reserve more pasta water than you think you need; you can always add more. Leftovers keep in an airtight container in the fridge for up to 3 days.
