Plumcake di zucchine: equilibrato, proteico e saziante, perfetto per chi cerca un piatto unico leggero e nutriente
Every time I set this zucchini savory cake on a potluck table, the same thing happens. Someone takes a small slice because it looks plain, then comes back for a bigger one.
It is soft, it is creamy, and it slices cleanly, which matters a great deal when a dish has to travel from your kitchen to somebody else’s dining room.
Here is what surprises people most. There is no butter in it, no puff pastry, and no brisée. The tenderness comes from eggs, milk, a modest amount of flour, and the vegetables themselves.
The recipe comes from an Italian kitchen and was written by Maria Di Bianco, who holds a degree in Food Science and Nutrition. That explains its double personality. It reads like a nutrition lesson and tastes like Sunday lunch. I have kept her quantities and her method exactly as they are, because they already work.
What I appreciate most is that it behaves like a complete meal instead of a side dish. You can serve it for lunch, and you can serve it for a light dinner, which is not something you can say about most savory bakes.

Zucchini do a lot of quiet work here. They are mostly water, they bring potassium, and they contribute soluble fiber, which is one reason the finished cake feels light rather than heavy on the plate.
The potato adds slow release carbohydrates, the kind that keep you steady instead of spiking and dropping an hour later. The eggs, the cream cheese, and the grated Parmigiano Reggiano supply complete proteins together with fats that make a single slice genuinely satisfying.
That combination is why one piece holds you for hours. Fiber, protein, and moderate complex carbohydrates arrive in the same bite, and that is a very different experience from eating a pastry shell with a little filling inside it.
Because the butter and the pastry are gone, this savory cake is lighter and easier to digest than a traditional savory tart.
The source recipe describes it as suitable for a normocaloric, balanced diet that is low in simple sugars, thanks to its fiber, its protein, and its moderate complex carbohydrate content.

It does contain dairy, so it is not a dairy free dish, but it is a balanced one.
A few practical numbers before we start. The recipe serves 6. Preparation takes about 30 minutes, baking takes 40 to 45 minutes, and the total time is about 1 hour and 15 minutes.
You bake it at 180 degrees Celsius, which is about 350 degrees Fahrenheit, in a static oven, meaning the conventional setting without a fan. A rectangular pan of about 24 by 18 centimeters is the right size.
It also keeps beautifully. You can make it a day ahead and store it in the refrigerator for several days. In my experience it is at its best slightly warm or at room temperature, which makes it an easy dish to carry to a church supper, a picnic, or a weeknight table where everyone eats at a different hour.
One more reason this cake earns a permanent spot in my rotation is that it is forgiving. You can assemble it in the morning, bake it in the afternoon, and serve it in the evening without any last minute stress. There is no pastry to roll, no butter to soften, and no delicate shell to worry about.

Ingredienti
Nothing on this list is exotic, and if you bake at all you probably have most of it already. The one item worth a second look is the leavening, which is the type sold for savory baked dishes rather than for sweet cakes.
| Ingredient | Amount |
|---|---|
| Zucchini | 2 medium, about 400 grams |
| Fine salt | 1 teaspoon |
| Freshly ground black pepper | Half a teaspoon |
| Extra virgin olive oil | 2 tablespoons |
| Large eggs | 4 |
| Sugar, optional | 1 tablespoon |
| Whole milk | 100 milliliters |
| Type 00 flour | 120 grams |
| Baking powder for savory preparations | 11 grams |
| Potato | 1 medium, about 150 grams |
| Onion | 1 small |
| Spreadable cream cheese | 100 grams |
| Grated Parmigiano Reggiano | 80 grams |
- The sugar is listed as optional, and its purpose is to balance the natural acidity of the vegetables rather than to sweeten the cake. Leave it out if you prefer.
- Type 00 flour is finely milled, and it is what gives the batter its smooth, fluid texture.
- The baking powder here is the savory kind, and 11 grams is more than a single small packet. Weigh it instead of estimating.
- Whole milk and full fat cream cheese are part of the original balance. They build the creamy crumb and help the slice feel satisfying.
For equipment you need a nonstick skillet, a hand whisk, and a rectangular pan about 24 by 18 centimeters. Parchment paper is optional if you would rather not grease the pan.
Procedimento
The method has three moving parts: the zucchini, the onion, and the liquid batter. Once those are ready, assembly takes about five minutes. Read through the steps once before you begin, because the oven needs to be fully hot when the pan goes in.
- Wash the zucchini thoroughly and slice them into thin rounds about 5 millimeters thick. Even slices soften at the same rate.
- Heat 1 tablespoon of the extra virgin olive oil in a nonstick skillet. Cook the zucchini with a pinch of salt and pepper for about 5 minutes, until they begin to soften slightly. You want pliable slices, not browned ones.
- Peel the potato and cut it into small cubes about 1 centimeter per side. Cutting them small is what allows a raw potato to cook through inside the cake.
- Finely chop the onion and sauté it in the second tablespoon of olive oil over low heat until lightly golden.
- Preheat the oven to 180 degrees Celsius in static mode. Lightly grease a rectangular pan about 24 by 18 centimeters, or line it with parchment paper.
- In a large bowl, beat the eggs with the sugar and a pinch of black pepper. Add the milk and mix vigorously.
- Sift the flour together with the baking powder, then incorporate it little by little into the liquid mixture, whisking by hand until you have a smooth and fluid batter.
- Arrange half of the cooked zucchini over the bottom of the pan. Spread the raw potato cubes and the golden onion evenly on top.
- With the help of a spoon, distribute the spreadable cheese in small dollops over the entire surface.
- Pour the batter over the vegetables, spreading it evenly so that everything is covered.
- Arrange the remaining zucchini on the surface, neatly or decoratively, and finish with the grated Parmigiano Reggiano.
- Bake for 40 to 45 minutes, until the surface is golden and the texture is compact. Check doneness by inserting a toothpick, which should come out dry.
- Remove the pan from the oven and let the cake cool for at least 10 minutes before slicing and serving. This rest allows the structure to stabilize and improves the cut.
Why does the order matter? When you put half the zucchini on the bottom, then the raw potato and the golden onion, then the cheese, then the batter, and finally the remaining zucchini with Parmigiano on top, you build a soft vegetable base under a golden surface.
Stir everything together instead and the zucchini sink to the middle and the contrast disappears.
The batter should pour like a thick pancake batter. Sifting the flour with the baking powder is what keeps it free of lumps, and a hand whisk gives you better control than a machine for this small quantity.
The toothpick test is the one to trust here, because the cake is dense and moist. A dry toothpick, a golden surface, and a compact center all point to the same thing. It is done. If the center still looks loose, give it five more minutes and check again.
Let it rest for at least 10 minutes before slicing. The structure sets, the crumb tightens, and the slices come out clean.
If you want to get ahead, cook the zucchini and the onion earlier in the day and keep them in the refrigerator. Bring them back to room temperature before you assemble the cake.
Storage is simple. Keep the cake covered in the refrigerator and it will hold for several days. It also travels well, which is why I often make it the night before a gathering.
Serve it slightly warm, at room temperature, or cold from the fridge with a sharp green salad on the side. Cut it into six generous slices for a main course, or into small squares for a buffet table.
Nutritional summary. This savory zucchini cake brings together fiber from the vegetables, complete protein from the eggs and the cheeses, and moderate complex carbohydrates from the potato and the flour.
The source recipe describes it as a complete and balanced preparation that offers good satiety and glycemic stability, and that fits a normocaloric diet low in simple sugars.
It is not a low calorie dish and it is not dairy free, but it is a genuinely balanced one.

FAQs
How do you make a soft and creamy zucchini cake without butter?
To make this soft and creamy zucchini cake, you cook sliced zucchini in olive oil, then layer them with raw potato cubes and sautéed onion in a pan. You pour a batter of eggs, milk, flour, and baking powder over the vegetables, add dollops of cream cheese, and top with remaining zucchini and Parmigiano Reggiano. Bake at 180°C for 40 to 45 minutes until golden and a toothpick comes out dry.
Is this zucchini savory cake healthy and suitable for a light dinner?
Yes, this zucchini savory cake is a healthy choice for a light dinner because it is made without butter or pastry, reducing fat and calories. The zucchini provides water, potassium, and fiber, while eggs and Parmigiano Reggiano offer quality protein for satiety. It is a balanced single course with complex carbohydrates from the potato and moderate fat, supporting digestive well-being and glycemic stability.
Can you freeze zucchini savory cake for later use?
Yes, you can freeze zucchini savory cake for later use. Allow the cake to cool completely, then wrap it tightly in plastic wrap and place it in an airtight container or freezer bag. It will keep well in the freezer for up to one month. Thaw overnight in the refrigerator and reheat in a moderate oven to restore its texture.
What cheese works best in a zucchini savory cake recipe?
The recipe uses two cheeses: spreadable cream cheese for moisture and a subtle tang, and grated Parmigiano Reggiano for a nutty, savory flavor. Cream cheese replaces butter to keep the cake creamy without added fat, while Parmigiano Reggiano adds umami and helps create a golden crust. Full-fat options improve satiety and tenderness, but low-fat versions can be substituted without drastically changing the texture.
