Baked Manicotti

2 c. spaghetti sauce
1 egg, lightly beaten
2 c. ricotta cheese
2 c. shredded mozzarella cheese, divided
1/2 c. grated parmesan cheese
1/4 basil pesto sauce
12 manicotti shells, cooked, rinsed in cold water

Preheat oven to 350° F. Spread 3/4 c. of the spaghetti sauce on bottom of 9x13 baking dish. Mix egg, ricotta, 1½ c. mozzarella, parmesan, and pesto sauce until well-blended. Spoon cheese mixture into large resealable plastic bag. Using scissors, cut off one of the bottom corners of the bag. Fill manicotti shells, one at a time, squeezing cheese mixture into both sides of each shell. Place in baking dish; pour remaining 1¼ c. spaghetti sauce over manicotti. Cover with aluminum foil. Bake 40 minutes or until heated through. The last 5 minutes of cooking, sprinkle more mozzarella cheese over top and remove aluminum foil to allow to melt and brown slightly.
