Method
- Heat the oven to 375°F with the rack in the center, and spray a 9x13-inch dish. Fill the 6-quart pot with 4 quarts of water and cover it. Set the ricotta on the counter.
- Heat the olive oil in the skillet over medium-high heat. Cook the beef for 6 to 8 minutes, pressing it into pea-sized crumbles, until no pink remains and the edges brown. Set the covered pasta pot on high heat.
- Stir in the onion and cook for 4 minutes, until soft and see-through. Add the garlic and tomato paste and cook for 1 minute, until the paste turns brick red.
- Add the crushed tomatoes, tomato sauce, oregano, basil, 1 teaspoon salt, 1/2 teaspoon pepper, and sugar. Simmer over medium-low heat for 15 minutes, until a spoon dragged across the pan leaves a trail.
- Add 2 tablespoons salt to the boiling water and cook the ziti for 8 minutes, about 3 minutes under the box time, until it bends but still has a firm, pale center. Drain without rinsing.
- Stir the ricotta, egg, 1/2 cup Parmesan, parsley, 1/4 teaspoon salt, and 1/4 teaspoon pepper until smooth and flecked with green.
- Stir the ziti into 3 cups of sauce until every piece looks glossy and red.
- Spread 1 cup of sauce in the dish, then add half the sauced pasta in an even layer.
- Drop the ricotta mixture over the pasta in 2 tablespoon mounds, then add the remaining pasta and the last of the sauce, until no dry noodles show.
- Sprinkle the mozzarella and remaining 1/4 cup Parmesan over the top, until the cheese reaches every edge.
- Cover tightly with foil sprayed with cooking spray and bake at 375°F for 20 minutes, until the sauce bubbles at the edges.
- Uncover and bake for 15 to 20 minutes more, until the cheese is golden in spots and the center reads 165°F. For deeper color, broil on high for 1 to 2 minutes, watching closely.
- Rest for 10 minutes, until the bubbling settles, then cut into 8 squares.
Notes
Storage: Refrigerate leftovers for 3 to 4 days or freeze baked squares for up to 3 months.
Make ahead: Build the dish through the final sauce layer, refrigerate up to 24 hours, then add the cheese and bake covered for 30 minutes instead of 20.
Salt: Amounts are for Diamond Crystal. Use half as much of Morton kosher salt or table salt.
