Spaghetti Pie

8 oz. cooked/drained spaghetti
1/2 c. parmesan cheese
1 egg
1 c. sour cream
1 lb. ground beef, browned
1 jar pasta sauce
8 oz. mozzarella cheese

Cook spaghetti per package directions (I usually cook a little longer since this dish is baked & the noodles tend to dry out more while baking). Drain spaghetti, then stir in parmesan cheese & egg. Pour noodle mixture into pie plate, making sure to press noodles against sides of pie plate as well for "crust." Place sour cream over top of noodle mixture (just the center of the noodles, not up the sides). Brown hamburger, drain if necessary, then add pasta sauce. Pour this mixture in the center of the pie plate on top of the sour cream. Top with mozzarella cheese & bake in a 350 degree oven for 30 minutes. You can save some pasta sauce to put on plates under servings of pie.
