Baked Ziti

This baked ziti recipe uses a blend of three cheeses to make it gooey and absolutely delicious. It is easy to make, but tastes like it took hours of slaving in the kitchen. This was the very first pasta dish I made for Casey, back when we were just dating. It turned out well then, and it's never let me down since!!

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

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. Spray 9x13 inch baking dish with non-stick spray.
4. Layer ingredients in the dish 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.
5. Bake for 30 minutes in the preheated oven, or until cheeses are melted. I love this dish with Caesar Salad and crunchy french bread!
