This creamy baked ziti recipe is an easy way to fill up the whole family. It can be made ahead of time if you prefer, or make it and bake it all at once.
Preheat oven to 350°F and butter a 9x13" baking dish.
Bring a large pot of salted water to a boil and cook 1 pound dry ziti pasta until al dente. Drain and set aside.
In a large skillet, brown 1 pound lean ground beef seasoned with ½ teaspoon salt, ¼ teaspoon pepper and ½ teaspoon garlic powder over medium heat. Add diced 1 onion and cook until translucent.
Stir in the 48 ounces spaghetti sauce and simmer 15 minutes.
Layer in the prepared casserole dish as follows: ½ of the ziti, ½ of the meat sauce mixture, 6 ounces provolone cheese, 1½ cups sour cream, remaining ziti, remaining sauce mixture, then 6 ounces mozzarella cheese. Sprinkle the top with 2 Tablespoons Parmesan cheese cheese.
Bake for 30 minutes or until cheeses are melted. (If you made it ahead of time, pull casserole out of the refrigerator while the oven preheats and bake 45 minutes or so or until heated through and bubbly.)
Notes
If you can't find ziti, any tubular shape of pasta will work. Rigatoni and penne are great options.
Feel free to use Italian sausage or ground turkey in place of the hamburger. It is delicious both ways.
