Zucchini has a gentle flavor, which is exactly what makes it so useful in a sauce like this. Once cooked until completely tender, it creates a naturally creamy base without the need for cream, while toasted pine nuts, aged cheese, garlic, and extra virgin olive oil give the sauce depth and structure. Fresh mint and finely grated lemon zest keep everything bright. The result sits somewhere between a vegetable purée and a pesto: smooth, dense, fragrant, and rich enough to coat pasta without feeling heavy. At Mama Florence Cooking School, this is the kind of sauce that shows how much can happen with a short ingredient list. The zucchini brings softness, the pine nuts add richness, Parmigiano and Pecorino give salt and savoriness, and mint and lemon lift the whole thing at the end.
This zucchini sauce follows the same broad idea as pesto: vegetables, nuts, cheese, garlic, and olive oil are blended together into a thick, emulsified dressing. What makes it different from a traditional basil pesto is that the zucchini is cooked first. Blanching softens the vegetable completely and gives the finished sauce its velvety texture. Once cooled, the zucchini is blended with toasted pine nuts, Parmigiano Reggiano, Pecorino Romano, garlic, mint, and lemon zest while extra virgin olive oil is streamed in gradually. The result is milder and creamier than a classic basil pesto, but it still has enough acidity, cheese, garlic, and herbs to stand up to fresh pasta. For a more traditional pesto, our Fresh Basil Pesto uses basil, pine nuts, almonds, Parmigiano, Pecorino Romano, garlic, and olive oil.
Zucchini Sauce Ingredients
• 300 gr fresh zucchini • 30 gr pine nuts • 40 gr grated Parmigiano Reggiano • 20 gr grated Pecorino Romano • Approx. 70 ml extra virgin olive oil • ½ garlic clove, germ removed • 1 teaspoon finely grated zest from an unsprayed lemon • 10–12 fresh mint leaves • Fine salt, to taste • Freshly ground black pepper, to taste
1. Prepare the Zucchini and Mint
2. Cook the Zucchini
3. Toast the Pine Nuts
4. Build the Sauce
5. Emulsify
6. Season
The two cheeses play slightly different roles. Parmigiano Reggiano gives the sauce a rounded, savory depth, while Pecorino Romano brings a sharper, saltier edge. Together, they keep the mild zucchini from disappearing behind the olive oil and nuts. The balance is deliberate: 40 g Parmigiano to 20 g Pecorino Romano, enough to give the sauce character without turning it into a cheese sauce.
The recipe specifies removing the inner germ from the garlic before blending. Because the garlic is used raw, even half a clove can have a noticeable effect on the finished sauce. Removing the germ helps keep the garlic more restrained so it supports the zucchini, mint, and lemon rather than dominating them.
This sauce works particularly well with fresh pasta because its dense texture can cling easily to the surface of the noodles. If using it with pasta, loosen the sauce gradually with a small amount of hot pasta cooking water until it reaches the consistency you want. Add the water a little at a time so the sauce remains creamy rather than becoming thin. It would pair especially well with our Fresh Egg Tagliatelle, where the broad ribbons give the zucchini sauce plenty of surface area to coat. For a more rustic Tuscan shape, try it with Fresh Pici Pasta, whose thicker strands can stand up well to a dense vegetable sauce. It can also be spread over toasted bread or served as part of an antipasto when you want something lighter than a richer cheese or meat-based topping.
The zucchini should arrive first: soft, fresh, and subtly sweet. Then come the toasted pine nuts and aged cheeses, giving the sauce richness and savory depth. Garlic stays quietly underneath, while lemon zest and mint lift the finish and prevent the sauce from feeling too dense. The olive oil binds everything together into a smooth, glossy texture. The best bite should feel creamy without tasting heavy, with the freshness of the zucchini still recognizable underneath the cheese, nuts, and herbs.
If you like vegetable-based sauces, our Fresh Basil Pesto is the natural comparison: brighter, more herbal, and built around raw basil rather than cooked zucchini. For another Tuscan green sauce with a completely different personality, our Tuscan Kale Pesto with Fresh Maltagliati combines cavolo nero with anchovy, garlic, olive oil, and toasted breadcrumbs. You can also make Fresh Egg Tagliatelle or Fresh Pici Pasta from scratch and use this zucchini sauce as the dressing.
At Mama Florence Cooking School, a good pasta dish is never only about the pasta. The sauce has to suit the shape, texture, and weight of the noodle, and vegetable sauces like this one are a useful lesson in balance: enough cheese and oil to give body, enough acidity and herbs to keep the flavors fresh, and enough pasta water to bring everything together at the end. Our Pasta Making Cooking Classes in Florence explore fresh dough, regional shapes, fillings, and sauces alongside our chefs. For a more focused introduction to handmade pasta, our Traditional Italian Pasta Cooking Class teaches the fundamentals of mixing, rolling, shaping, and finishing fresh pasta with sauces that suit each preparation.
Q: Is this zucchini sauce the same as zucchini pesto? A: It follows a pesto-style method using zucchini, pine nuts, cheese, garlic, herbs, and olive oil, but the zucchini is cooked before blending rather than used raw.
Q: Do I need to peel the zucchini? A: No. The recipe only calls for washing the zucchini, trimming the ends, and cutting them into cubes.
Q: How long should the zucchini cook? A: Blanch the zucchini in lightly salted boiling water for approximately 15 minutes, until completely tender.
Q: Why should the zucchini cool before blending? A: The recipe calls for the cooked zucchini to cool completely at room temperature before it is combined with the other ingredients.
Q: Do the pine nuts need to be toasted? A: Yes. Toast them gently over low heat for a few minutes, taking care not to burn them.
Q: What cheeses are used in the sauce? A: The recipe uses 40 g Parmigiano Reggiano and 20 g Pecorino Romano.
Q: How much olive oil should I use? A: Use approximately 70 ml extra virgin olive oil, streamed in gradually while blending.
Q: Can I leave out the mint? A: The supplied recipe specifically includes 10–12 fresh mint leaves, so mint is part of the intended flavor profile.
Q: Why use lemon zest instead of lemon juice? A: The recipe uses 1 teaspoon finely grated lemon zest, which adds citrus fragrance without adding extra liquid to the sauce.
Q: What pasta works with zucchini sauce? A: Fresh tagliatelle and pici would both work well because the sauce is dense enough to cling to the pasta.
