Baked Ziti

This is my staple for new mommies! It is great for guests, the kids love it, reheats well, and I prefer it to lasagna. It is easy to make in bulk too.

Ingredients:

1 pound dry ziti pasta
1 onion, chopped
1 pound lean ground beef
2 (26 ounce) jars spaghetti sauce
6 ounces provolone cheese, sliced
1 1/2 cups sour cream
6 ounces mozzarella cheese, shredded
2 tablespoons grated Parmesan cheese

Directions:

1) Bring a large pot of lightly salted water to a boil. Add ziti pasta, and cook until al dente, about 8 minutes; drain.
2) In a large skillet, brown onion and ground beef over medium heat. Add spaghetti sauce, and simmer 15 minutes.
3) Preheat the oven to 350 degrees F (175 degrees C). Butter a 9x13 inch 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.
4) Bake for 30 minutes in the preheated oven, or until cheeses are melted.

Once I went crazy with the sour cream and it didn't taste very good, so definitely go easy on the sour cream. I usually make it with the Trader Joe's multigrain penne and it still tastes great.
