Bring a large pot of salted water to a rolling boil, then add the ziti. Cook until just al dente, about 8 minutes, then drain and set aside.
Preheat your oven to 180°C/350°F. Lightly grease your baking dish with a little olive oil.
In a skillet, heat the olive oil over medium heat and sauté minced garlic until fragrant, about 30 seconds. Pour in the marinara sauce, bring to a gentle simmer, and season with salt and pepper. Let it simmer for 5 minutes to deepen the flavor.

In a large mixing bowl, combine the drained pasta with the warm marinara sauce, stirring gently to coat all the noodles evenly.

Add dollops of ricotta cheese over the pasta, then sprinkle half of the shredded mozzarella and Parmesan cheese on top. Gently fold everything together to distribute the cheeses evenly.

Transfer half of the pasta mixture into the prepared baking dish. Repeat with the remaining pasta and cheeses, layering neatly. Sprinkle breadcrumbs over the top if using for added crunch.
1 pound pound ziti pasta
Bake in the preheated oven for 25-30 minutes, until the cheese is bubbling and golden on top. If the top browns too quickly, tent with foil to prevent burning.
Remove from oven and let the baked ziti rest for 5 minutes. This helps the layers set and makes serving easier.
Garnish with freshly chopped herbs if desired, then scoop onto plates and enjoy the cheesy, crispy edges and gooey center of this comforting dish.
