Step 1: Prepare the Lasagna Noodles

Bring a large pot of salted water to a boil. Add the lasagna noodles and cook them according to package instructions until they are al dente. Stir occasionally to prevent sticking.

Once cooked, drain the noodles and lay them flat on a baking sheet lined with parchment paper or lightly oiled. This prevents them from sticking together and tearing later when you roll them.

Step 2: Make the Tomato Pesto Sauce

Heat olive oil in a large skillet over medium heat. Add the finely chopped onion and cook for about 4 to 5 minutes until softened and slightly translucent.

Stir in the minced garlic and cook for another minute until fragrant. Be careful not to let the garlic burn.

Pour in the crushed tomatoes and stir well. Allow the sauce to simmer gently for about 10 minutes so the flavors can develop.

Add the basil pesto and mix thoroughly. Season with salt and pepper to taste. Let the sauce simmer for another few minutes, then remove from heat.

Step 3: Prepare the Ricotta Filling

In a large mixing bowl, combine the ricotta cheese, chopped parsley, egg, and grated Parmiggiano Reggiano.

Mix everything together until smooth and well incorporated. The egg helps bind the filling, ensuring it stays creamy yet firm after baking.

Add the chopped grilled vegetables and gently fold them into the mixture. Season with salt and pepper according to your taste.

Step 4: Assemble the Lasagna Rolls

Preheat your oven to 375°F or 190°C.

Spread a thin layer of the prepared sauce at the bottom of a baking dish. This prevents sticking and adds flavor to the base.

Take one lasagna noodle and spread an even layer of the ricotta filling across it. Do not overfill, as this can make rolling difficult.

Carefully roll the noodle from one end to the other, creating a spiral. Place the roll seam side down in the baking dish.

Repeat the process with the remaining noodles and filling.

Step 5: Add Sauce and Cheese

Once all the rolls are arranged in the baking dish, pour the remaining sauce evenly over the top.

Sprinkle the shredded mozzarella over the rolls, followed by the grated Parmiggiano. This combination creates a beautifully melted and slightly golden topping.

Step 6: Bake the Lasagna Rolls

Cover the baking dish loosely with foil and place it in the preheated oven.

Bake for about 25 minutes. Then remove the foil and continue baking for another 10 to 15 minutes until the cheese is melted and slightly golden.

Allow the dish to rest for about 10 minutes before serving. This helps the rolls set and makes them easier to serve.
