Step 1: Preheat Your Oven
Set your oven to 375°F (190°C).
Make sure your baking rack is in the center to ensure even cooking.
This gives you time to prepare the rest while the oven heats up.

Step 2: Cook the Ziti
Boil the pasta in salted water according to package instructions until al dente.
Be sure to reserve a half cup of pasta water before draining—it can help loosen the sauce later if needed.
Set the drained pasta aside while you work on the sauce.

Step 3: Make the Meat Sauce
In a large skillet over medium heat, cook the ground beef and diced onion.
Sauté until the beef is browned and the onions are soft, about 5–7 minutes.
Add the minced garlic and cook for another minute until fragrant.

Step 4: Add the Tomatoes and Seasonings
Stir in the crushed tomatoes, Italian seasoning, salt, and pepper.
Let the sauce simmer for 10 minutes, stirring occasionally to blend all the flavors.
This step fills the kitchen with the most mouthwatering aroma—it smells like an Italian trattoria.

Step 5: Mix Pasta with Sauce and Ricotta
In a large bowl, combine the cooked ziti with the warm meat sauce.
Fold in the ricotta cheese until everything is well mixed and creamy.
If the mixture feels too thick, add a splash of the reserved pasta water to loosen it up.

Step 6: Layer in the Baking Dish
Grease your 9×13-inch baking dish with butter or oil to prevent sticking.
Spoon in half of the pasta mixture and spread it evenly with a spatula.
Sprinkle half of the mozzarella and Parmesan cheeses over this layer.

Step 7: Repeat the Layers
Add the rest of the pasta mixture on top, spreading it evenly.
Top with the remaining mozzarella and Parmesan, creating a thick cheesy layer.
This final step is what gives the dish that golden, bubbly crown of glory.

Step 8: Bake Covered, Then Uncovered
Cover the dish tightly with foil and bake for 25 minutes.
Then remove the foil and continue baking for 15 more minutes, until the cheese is golden and bubbly.
Let it sit for 5 minutes before serving so it sets up properly.

Step 9: Garnish and Serve
Sprinkle chopped parsley over the top just before serving for a pop of color.
Slice into generous portions and serve hot with garlic bread or salad.
Get ready for second helpings—this dish always disappears fast!
