Creamy Baked Ziti

This one's from kraftfoods.com.  They always have great ideas.

4 cups ziti pasta, uncooked (I used penne and it was great)
1 jar (26 oz.) marinara sauce
1 can (14-1/2 oz.) diced tomatoes, undrained
6 oz. (3/4 of 8-oz. pkg.) PHILADELPHIA Cream Cheese, cubed
3/4 cup BREAKSTONE'S or KNUDSEN Sour Cream
1 pkg. (8 oz.) KRAFT Shredded Mozzarella Cheese
1/3 cup KRAFT Grated Parmesan Cheese

HEAT oven to 375ºF.


COOK pasta in large saucepan as directed on package, omitting salt. Remove from pan; drain. Meanwhile, add marinara sauce, tomatoes and cream cheese to same pan; cook on medium heat 5 min. or until cream cheese is melted and mixture is well blended, stirring frequently. Return pasta to pan; mix well.

LAYER half the pasta mixture in 13x9-inch baking dish; cover with layers of sour cream, 1 cup mozzarella and remaining pasta mixture. Top with remaining mozzarella and Parmesan.


BAKE 20 min. or until heated through.
