Baked Ziti Pasta Casserole Recipe

Bring a large pot of salted water to a boil and cook the ziti pasta according to package instructions until just al dente. Drain the pasta and set aside, ensuring it does not overcook since it will continue cooking in the oven.

In a deep pan or Dutch oven over medium-high heat, cook the ground beef and chopped onion together, breaking up the meat with a spatula, until fully cooked and the onion is softened, about 5 to 7 minutes. Add minced garlic, salt, and black pepper, and sauté for another minute to release flavors.

Pour in the marinara sauce, stir to combine, and bring to a gentle simmer. Let it cook for 5 minutes to blend flavors, then remove from heat.

Chop half of the basil leaves finely and mix them into the ricotta cheese. Then stir the ricotta into the meat sauce, followed by adding the cooked pasta. Gently stir until noodles are coated with the creamy sauce, preserving the ricotta's texture.

Spread a ladle of the meat sauce into the bottom of a 9×13 inch casserole dish. Transfer half of the pasta mixture into the dish, then sprinkle with half of the shredded mozzarella and half of the grated parmesan cheese. Add the remaining pasta, and top with the rest of the mozzarella and parmesan cheeses.

Ensure the edges of the casserole dish are clear of excess cheese to prevent burning. Bake in a preheated oven at 350 degrees Fahrenheit for 25 minutes until bubbly. For a golden browned top, broil on high for 1 to 2 minutes while watching carefully.

Remove from oven and let the baked ziti rest for 5 minutes to settle. Garnish with remaining fresh basil leaves if desired, then serve warm.
