Baked Italian Casserole

Place a large skillet over medium heat. Add the ground beef and onion to the skillet, and cook them together until the meat is no longer pink and the onions are translucent, about 5 - 7 minutes.

Once the meat is cooked, drain off the fat from the skillet.

Add the spaghetti sauce to the drained beef and onion mixture in the skillet. Stir well to combine the ingredients.

While the meat is cooking, fill another pot with water and bring it to a boil. Add the ziti to the boiling water and cook according to the package directions.

Preheat your oven to 350°F (176.7°C).

Spray a 9x13 - inch baking pan with cooking spray.

Spread half of the cooked ziti noodles evenly across the bottom of the prepared baking dish.

Layer the provolone cheese over the noodles in the dish.

Next, layer the sour cream on top of the provolone cheese.

Then, layer half of the meat - sauce mixture on top of the sour cream.

Add the remaining cooked ziti noodles on top of the meat - sauce layer.

Sprinkle 6 ounces of shredded mozzarella cheese evenly over the top of the ziti noodles.

Top the casserole with the remaining meat - sauce mixture, parmesan cheese, and the remaining shredded mozzarella cheese.

Place the baking dish in the preheated 350°F (176.7°C) oven and bake for 35 minutes.

If you'd like the top of the casserole to get a touch of brown, turn the oven to broil on high and broil the casserole for 2 - 3 minutes. Keep a close eye on it to prevent burning!
