Cook the pasta according to package instructions until al dente. Drain and set aside, reserving 1/2 cup of the pasta water.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Add the spiralized or sliced zucchini to the skillet and cook for 3-4 minutes, stirring occasionally, until slightly softened.
Pour in the vegetable broth and almond milk, then stir in the lemon juice, lemon zest, dried basil, salt, and pepper. Bring the mixture to a simmer.
Add the cooked pasta to the skillet, tossing to combine. If the sauce is too thick, add a bit of the reserved pasta water until you reach your desired consistency.
Cook for an additional 2-3 minutes, allowing the flavors to meld together. Adjust seasoning if necessary.
Serve warm, garnished with fresh parsley and optional grated Parmesan cheese or nutritional yeast.
