Cheesy baked tortellini casserole

20-ounce package refrigerated or frozen tortellini
1 pound ground beef
1 8-ounce package cream cheese
2 cups shredded mozzarella cheese
2 cups grated or shredded parmesan cheese
1 24-ounce jar of marinara or pasta sauce

Cook the pasta al dente, according to package directions; drain and set aside. In a large skillet, brown the ground beef with a little garlic, salt, pepper and Italian seasoning. Remove the excess grease from the beef and mix with a 24-ounce jar of marinara or pasta sauce. Add the cream cheese to the mixture and allow it to melt. Stir well and then gently toss the cooked tortellini into the pan. Pour the mixture into a greased 9-by-13 baking dish and then top with mozzarella and Parmesan cheese. Bake in the center rack of a 350-degree oven for about 20 minutes, and then bake an additional 2 to 3 minutes with the broiler on.
