Creamy Zucchini Lemon Pasta
Ingredients
- 12 oz 340g pasta (spaghetti, fettuccine, or linguine work best)
- 3 medium zucchini grated or finely diced
- 3 tablespoons olive oil
- 4 cloves garlic minced
- 1 shallot finely diced (or ¼ cup diced sweet onion)
- Zest and juice of 1 large lemon
- ½ cup heavy cream or half-and-half for a lighter version
- ⅔ cup freshly grated Parmesan cheese plus more for serving
- ¼ cup fresh basil leaves thinly sliced (chiffonade)
- ½ teaspoon red pepper flakes optional
- Salt and freshly ground black pepper to taste
Instructions
- Prepare the pasta water. Bring a large pot of generously salted water to a rolling boil. The water should taste like the sea—this is crucial for flavorful pasta.
- Cook the pasta according to package directions until al dente. Before draining, reserve 1 cup of the starchy pasta water, then drain the pasta.
- Prepare the zucchini. While the pasta cooks, grate the zucchini using the large holes of a box grater, or cut into small dice. If grated, gently squeeze out excess moisture using a clean kitchen towel.
- Sauté the aromatics. Heat olive oil in a large skillet over medium heat. Add the shallot and cook for 2-3 minutes until softened but not browned. Add the garlic and cook for another 30 seconds until fragrant.
- Cook the zucchini by adding it to the skillet. Increase heat to medium-high and cook for 5-7 minutes, stirring occasionally, until the zucchini has softened and most of its moisture has evaporated.
- Add the lemon. Stir in the lemon zest and half of the lemon juice, allowing it to sizzle for about 30 seconds to release its oils.
- Create the creamy sauce by reducing heat to medium-low and pouring in the heavy cream. Simmer gently for 2 minutes until it starts to thicken slightly.
- Add the pasta directly to the sauce. Toss to coat evenly, adding a splash of reserved pasta water if needed to loosen the sauce.
- Incorporate the cheese by removing the pan from heat and gradually sprinkling in the Parmesan while tossing continuously. This prevents the cheese from clumping and creates a smooth sauce.
- Finish and serve. Add the fresh basil, remaining lemon juice to taste, red pepper flakes if using, and season with salt and pepper. Serve immediately with extra Parmesan for sprinkling.
Notes
- For a silkier sauce, make sure to reserve enough pasta water. The starch in this water helps create that restaurant-quality consistency.
- The zucchini can be prepared up to a day ahead and stored in the refrigerator, which makes weeknight assembly even quicker.
- If you prefer a smoother texture, you can purée half of the cooked zucchini mixture before combining with the pasta.
- This dish is best enjoyed immediately, as the sauce can thicken upon standing. If needed, reheat with an additional splash of pasta water or cream.
- For extra depth of flavor, add a splash of white wine after cooking the zucchini and before adding the lemon and cream.

Common Mistakes to Avoid
- Not removing excess zucchini moisture: This can make your sauce watery instead of creamy. Take the time to squeeze grated zucchini or cook diced zucchini until moisture evaporates.
- Overcooking the pasta: Always aim for al dente as the pasta will continue cooking slightly when tossed with the hot sauce.
- Adding cheese while the pan is too hot: This will cause the cheese to clump rather than melt smoothly into the sauce. Always remove from heat first.
- Skipping the pasta water: This starchy liquid is essential for creating a silky sauce that clings to the pasta.
- Not tasting as you go: The brightness of lemons can vary greatly, so adjust the amount of lemon juice to your preference.
Alternatives & Substitutions
- Make it dairy-free: Substitute the heavy cream with coconut cream or cashew cream, and use nutritional yeast instead of Parmesan.
- Make it gluten-free: Use your favorite gluten-free pasta. Rice or corn-based pastas work particularly well with this sauce.
- Vegetable variations: Yellow summer squash works beautifully in place of or alongside zucchini. For extra nutrition, add a handful of baby spinach or peas during the final minute of cooking.
- Herb options: If basil isn’t available, substitute with fresh mint, parsley, or thyme for a different but equally delicious flavor profile.
- Protein additions: Top with grilled chicken, sautéed shrimp, or white beans to make it more substantial.
FAQs
Can I make this pasta ahead of time?
While best served fresh, you can prepare the zucchini sauce up to a day ahead and refrigerate it. When ready to serve, reheat the sauce gently, cook fresh pasta, and combine. You may need to add a splash of cream or pasta water to revive the consistency.
How do I prevent my sauce from becoming watery?
The key is properly managing the zucchini’s moisture. Either squeeze grated zucchini in a clean kitchen towel before cooking, or ensure you sauté diced zucchini long enough to evaporate excess liquid before adding the cream.
Will this recipe work with dried herbs instead of fresh?
Yes, though the flavor profile will change. If using dried herbs, add them earlier in the cooking process (with the garlic) and use about one-third the amount called for fresh. That said, fresh herbs really make this dish shine.
Can I use pre-grated Parmesan cheese?
Freshly grated Parmesan melts much better and has superior flavor compared to pre-grated versions, which often contain anti-caking agents. If you must use pre-grated, look for refrigerated varieties without additives.
How can I add more protein to this vegetarian dish?
Easily boost protein by adding white beans, pine nuts, or walnuts. For non-vegetarians, top with grilled chicken, seared scallops, or Italian sausage. Even a poached egg makes a delicious protein-rich addition.
