Baked Ziti

I know I posted this on my old blog. I hope I haven't posted it already on this one but I looked and can't find it. I made this the other night and forgot to take a photo. This is literally one of my family's favorites.

1 lb. dry Ziti pasta
1 onion, chopped
1 lb. lean ground beef of sausage (I use sausage, but not the spicy kind.)
If a pound is too much, use less.
2 (26 oz.) jars of spaghetti sauce
6 oz. Provolone cheese, sliced
1 1/2 cups of sour cream
6 oz. Mozzarella cheese, shredded
2 tbls. Parmesan cheese, grated (I use a lot more than that.)

Cook your pasta until al dente, about 8 minutes. Drain.

In a large skillet, brown onion and ground beef or sausage over medium heat. Add spaghetti sauce and simmer 15 minutes.

Preheat oven to 350 degrees. Pam a 9x13 baking dish.

Layer as follows: 1/2 of the ziti, provolone cheese, sour cream, 1/2 sauce mixture, remaining ziti, mozzarella cheese and remaining sauce mixture. Top with grated parmesan cheese.

Bake for 30 minutes in the preheated oven or until cheeses are melted.

*This recipe makes a lot. For those of you with small families, I would definately cut it in half and bake it in a 8x8 dish.
