The Secret to Silky and Firm Zucchini Lasagna

Slice the zucchini thinly lengthwise, using a mandoline or knife. Arrange the slices on a baking sheet, sprinkle generously with coarse salt, and let rest for 30 minutes. This is the crucial step to remove excess water from the zucchini.

Meanwhile, prepare the meat sauce. Heat the olive oil in a large pot over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the chopped garlic and cook for another minute, perfuming the kitchen.

Add the ground beef to the pan, breaking it up with a spoon. Cook until completely browned, draining excess fat if necessary. This initial browning of the meat adds depth to the sauce's flavor.

Incorporate the peeled tomatoes, tomato sauce, basil, oregano, salt, and black pepper. Stir well, reduce heat to low, cover, and let cook for at least 20 minutes, allowing the flavors to deepen.

Return to the zucchini. After resting, the slices will have released a lot of liquid. Use clean paper towels to squeeze and dry each slice very well. The professional technique is to press firmly, removing as much moisture as possible.

In a medium bowl, mix the ricotta, egg, half of the parmesan, a pinch of nutmeg, salt, and black pepper until a homogeneous paste is obtained. This mixture will be the creamy base between the layers of the lasagna.

Preheat the oven to 190°C. Assemble the lasagna in a baking dish of approximately 23x33 cm. Start with a thin layer of meat sauce at the bottom. This prevents the lasagna from sticking and distributes the flavor evenly.

Arrange a layer of zucchini slices over the sauce, overlapping them slightly. Cover with half of the ricotta mixture, followed by a portion of meat sauce and a layer of grated mozzarella. Repeat the layers of zucchini and fillings.

Finish with a final layer of zucchini, meat sauce, and all the remaining mozzarella cheese, along with the parmesan. This top layer should be generous, creating a golden and irresistible crust.

Place in the preheated oven and bake for 30-35 minutes, or until the lasagna is bubbling and the cheese on top is golden and gratinated. The short answer is: wait for the cheese to bubble and lightly toast to ensure the ideal point.

Remove from the oven and, the most important tip is: let the lasagna rest for at least 10-15 minutes before cutting and serving. This allows the layers to set, preventing it from collapsing when slicing and maintaining an impeccable presentation.
