The Inspiration Behind This Creamy Zucchini Pasta
I will never forget the first time I tasted a dish like this at Ristorante Lo Scoglio, a beautiful family-run restaurant overlooking the sea near Nerano and Marina del Cantone on the Amalfi Coast.
The dish was so simple: pasta, zucchini, basil and a luxurious creaminess that seemed impossible from such humble ingredients. It was one of those meals that stays with you long after the table is cleared.
Ever since that trip, I have wanted to create my own simpler version at home. And of course, it had to be oil-free and dairy-free.
This Spaghetti con Crema di Zucchine is not a traditional Spaghetti alla Nerano recipe. Instead, it is my whole-food, plant-based interpretation of that unforgettable combination of pasta and zucchini. Rather than frying zucchini in oil or finishing the dish with dairy cheese and butter, I blend tender zucchini with soaked almonds, nutritional yeast, garlic and pasta water to create a smooth, creamy sauce.
The result is lighter and brighter, while still delivering the comforting richness that made the original experience so memorable.
What Is Spaghetti con Crema di Zucchine?
Spaghetti con Crema di Zucchine simply means spaghetti with zucchini cream sauce.
In Italian cooking, zucchini is often paired with pasta because its mild sweetness and tender texture work beautifully with garlic, basil, lemon and savory cheeses. In this plant-based version, zucchini does more than add flavor: it becomes the foundation of the sauce itself.
In this version, the zucchini is steamed until tender, then blended with soaked almonds and pasta water to create a smooth sauce that wraps around the spaghetti beautifully.
What Makes This Creamy Zucchini Pasta Special
This is one of those recipes that proves creamy pasta does not require cream, butter or oil.
The zucchini becomes soft and mellow when steamed with onion and garlic. Blended almonds create a silky texture and subtle richness, while nutritional yeast adds savory depth. A squeeze of lemon and fresh basil brighten the entire dish so it never feels heavy.
It is:
- Whole-food, plant-based
- Oil-free and dairy-free
- Naturally creamy without processed cheese substitutes
- Easy enough for a weeknight meal
- A beautiful way to use fresh summer zucchini
- Elegant enough for a special dinner
The Secret to Creamy Pasta Without Dairy or Oil
Creaminess is not created by fat alone. It can also come from texture, starch and careful blending.
In this recipe, the sauce gets its creamy consistency from three simple elements:
Tender Zucchini
Steamed zucchini becomes soft enough to blend into a smooth, delicate base. It gives the sauce volume and a fresh garden flavor without making it heavy.
Soaked Almonds
Blanched almonds bring subtle richness and help create the luxurious mouthfeel normally associated with cream-based pasta sauces. Soaking them first makes them easier to blend smoothly.
Pasta Water
Do not forget to reserve some of the pasta cooking water before draining the spaghetti.
As pasta cooks, it releases starch into the water. When added to the zucchini-almond sauce, that starchy water helps loosen the consistency while giving it a smooth, silky finish that clings beautifully to every strand of spaghetti.
Because this recipe does not rely on oil, butter or dairy for richness, pasta water is especially important. It helps bring the sauce and pasta together, creating that velvety, finished texture that makes a simple pasta dish feel special.
Add it gradually, one splash at a time, until the sauce glides easily through the spaghetti without becoming thin or watery.

This is exactly the kind of technique I love teaching: once you understand how texture and starch work together, you can create creamy Italian dishes without relying on oil, butter or dairy.
Choosing the Best Zucchini
For the sweetest flavor and creamiest sauce, choose small to medium zucchini, ideally about 6 to 8 inches long.
Smaller zucchini tend to be:
- More tender
- Less watery
- Sweeter in flavor
- Easier to blend into a smooth sauce
Larger zucchini can still work, but they may contain more seeds and release additional moisture. If using very large zucchini, you may want to remove some of the soft seeded center before cooking.
Pro Tips for the Creamiest Zucchini Pasta
Follow these simple tips to create the silkiest sauce and bring out the fresh, delicate flavor of this creamy zucchini pasta. It is the kind of memorable dish your family and guests will ask you to make again and again.
- Soak the almonds for at least 2 to 4 hours, or overnight, for the smoothest sauce.
- Use small, tender zucchini for the sweetest flavor and least watery texture.
- Reserve more pasta water than you think you will need; it is the easiest way to adjust the final sauce.
- Blend the sauce until completely smooth before combining it with the pasta.
- Add lemon zest and basil at the very end so their flavors stay bright and fresh.
- Serve immediately, since creamy pasta sauces are at their silkiest right after tossing.
Serving Suggestions
This creamy zucchini pasta is beautiful served simply with fresh basil, lemon zest and a sprinkle of plant-based Parmesan or Pecorino.
You can also serve it with:
- A simple arugula salad with lemon dressing
- Roasted cherry tomatoes
- Grilled asparagus or broccolini
- White beans tossed with lemon and herbs
- Warm crusty whole-grain bread
For a particularly pretty summer plate, add a few ribbons of fresh basil and an extra touch of lemon zest just before serving.

Add-Ins and Substitutions
This Spaghetti con Crema di Zucchine is delicious as written, but it is also easy to adapt depending on how you plan to use it.
For a Lighter Sauce
Reduce the almonds to ½ cup and add an extra splash of pasta water, plant-based milk, or vegetable broth. The sauce will still be creamy but a little lighter.
For a Nut-Free Version
Replace the almonds with cooked cannellini beans or sunflower seeds. White beans produce a softer, lighter sauce, while sunflower seeds give the sauce a richer texture.
Add Sweet Peas
Fresh or frozen peas are a beautiful addition. Stir them into the pasta during the final minute of cooking for a pop of sweetness and color.
Add Mushrooms
Dry-sautéed or broth-sautéed mushrooms add savory depth and give the finished pasta a more substantial texture. Cook them separately and fold them into the pasta just before serving.
Add Extra Greens
Baby spinach or chopped arugula can be gently wilted into the hot pasta before serving.
Storing
This pasta is best enjoyed immediately while the sauce is smooth and silky.
Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it chills because of the almonds and starch from the pasta.
To reheat, place the pasta in a skillet over low heat with a splash of vegetable broth, water or unsweetened plant-based milk. Stir gently until the sauce loosens and becomes creamy again.

Ingredient Highlights
Zucchini
Zucchini is the foundation of this light, silky sauce. It provides vitamin C, potassium and fiber while adding moisture and volume without heaviness. Once steamed and blended, zucchini creates a wonderfully smooth base for creamy pasta sauces.
Whole-Grain Spaghetti
Whole-grain pasta adds more fiber than refined pasta while providing satisfying complex carbohydrates. That fiber helps make this dish more filling and supports digestive health, making it a nourishing foundation for a plant-based meal.
Blanched Almonds
Almonds create the rich, velvety texture in this dairy-free sauce. They contribute plant protein, fiber, vitamin E and magnesium, helping turn simple zucchini into a creamy, satisfying pasta sauce without butter, cream or oil.
Nutritional Yeast
Nutritional yeast gives the sauce a savory, lightly cheesy flavor without dairy. Depending on the brand, it may also be fortified with B vitamins, including vitamin B12, so check the package label if you rely on it as a source of added nutrients.
Lemon and Fresh Basil
Lemon juice and zest brighten the creamy sauce, while fresh basil adds fragrant summer flavor. Together, they help the pasta feel vibrant and balanced, allowing simple whole-food ingredients to shine.
The Bigger Picture
This Spaghetti con Crema di Zucchine is a beautiful example of how plant-based Italian cooking can be both comforting and nourishing. Instead of building creaminess with oil, butter or dairy, this recipe uses tender zucchini, almonds and starchy pasta water to create a luxurious sauce from whole plant ingredients.
Paired with whole-grain pasta, fresh herbs and lemon, it becomes a satisfying meal that celebrates vegetables rather than hiding them. It is simple, seasonal Italian-inspired cooking that delivers comfort, flavor and nourishment in every creamy bite.

Notes
❓Frequently Asked Questions
1. Is this the same as Spaghetti alla Nerano?
No. This recipe is inspired by the unforgettable pasta and zucchini flavors I experienced near Nerano, but it is my own whole-food, plant-based preparation. Traditional Spaghetti alla Nerano generally includes fried zucchini and dairy cheese. This version uses steamed zucchini and almonds to create creaminess without oil or dairy.
2. Can I make the sauce ahead of time?
Yes. The zucchini-almond sauce can be made one day in advance and refrigerated in an airtight container. Reheat it gently with a splash of pasta water, plant-based milk, or vegetable broth before tossing it with freshly cooked spaghetti.
3. Can I freeze zucchini cream sauce?
You can freeze the sauce by itself, although the texture may change slightly when thawed. Blend it again after reheating with a splash of plant-based milk or broth to restore its creamy texture. I do not recommend freezing the finished pasta dish.
4. Can I use another pasta shape?
Absolutely. Spaghetti is elegant and traditional for this style of dish, but linguine, fettuccine, fusilli or rotini will also work. Fusilli and rotini are especially good at capturing the creamy sauce in their twists.
