1 (16 oz) pkg uncooked ziti
1 lb ground beef (I use ground turkey)
1 onion, chopped
2 (26 oz) jars spaghetti sauce (I like using homemade)
12 oz sliced provolone cheese
12 oz sliced mozzarella cheese (I use shredded)
1 1/2 C sour cream
1/2 C Parmesan cheese
1/4 C chopped fresh basil
Preheat oven to 350 degrees and lightly grease (cooking spray) a 9x13 baking dish.
Cook pasta for 8-10 minutes, drain.
While pasta is cooking, brown meat and onion.
When brown, drain fat and add spaghetti sauce and simmer for 15 minutes.
Spread a little of the sauce on the bottom of the dish.
Layer 1/2 of the pasta, 1/2 of the provolone and mozzarella cheeses, 1/2 of the sauce and ALL of the sour cream.
Repeat with the rest of the pasta, provolone and mozzarella cheeses, sauce and top with all of the Parmesan cheese.
Sprinkle fresh basil on top.
Bake, uncovered, for 30-40 minutes.
