1In a large skillet, brown ground beef; add onions and sweat well. Drain then bring back to pan. Add both jars of sauce, garlic powder, chili powder, and sugar. Let cook for 1 hour to 1 1/2 hours or desired length of time. (Basically making spaghetti sauce so feel free to make it how you like it)
2Boil enough pasta for your 9"x13" casserole dish. Breaking pasta in half before putting in water, makes it easier to manipulate when layering in baking dish.
3In large bowl, mix ricotta, parmesan, 1 1/2 c. mozzarella, and egg. Set to side.
4When sauce is cooked to your liking, spread a think layer in bottom of baking dish. Layer with pasta. Now spread cheese mixture on top.
Repeat layers until you get to the top, ending with spaghetti sauce. Now top with 2.5 c. mozzarella cheese.
