# How to Make It:
01 - Preheat oven to 375°F. Select a 9x13-inch freezer-safe baking dish for optimal results.
02 - Bring a large pot of salted water to boil. Cook ziti until just al dente, approximately 2 minutes less than package directions. Drain and toss lightly with olive oil to prevent adhesion.
03 - Heat 2 tablespoons olive oil in a large skillet over medium heat. Add chopped onion and sauté until softened, about 4 minutes. Add minced garlic and cook for 1 additional minute.
04 - If using Italian sausage or ground beef, add to skillet and cook, breaking apart with spoon, until browned and cooked through. Drain excess fat if necessary.
05 - Stir in oregano, basil, red pepper flakes if desired, crushed tomatoes, tomato sauce, salt, pepper, and sugar. Simmer for 10 minutes, stirring occasionally. Remove from heat.
06 - In a mixing bowl, blend ricotta cheese, egg, Parmesan cheese, and 1 cup mozzarella until smooth and well incorporated.
07 - Spread 1 cup sauce across bottom of baking dish. Layer half the cooked pasta, followed by half the ricotta mixture, then half the remaining sauce. Repeat layers. Top with remaining 1 cup mozzarella cheese.
08 - Allow casserole to cool completely. Cover tightly with aluminum foil, label with date, and freeze up to 3 months.
09 - Preheat oven to 375°F. Bake covered for 60-75 minutes. Remove foil and bake uncovered for 20-25 minutes until bubbly and golden brown. For fresh baking, reduce covered time to 30 minutes, then uncover for 15 minutes.
10 - Allow casserole to stand for 10 minutes before portioning and serving.
