Boil lasagna noodles per instructions on the box. Drain when cooked.
Brown Italian sausage in olive oil on medium heat. When sausage is completely cooked, add tomato sauce, garlic powder, oregano and sugar.
Stir, then simmer for 5 minutes, or until sauce is bubbling.
Spoon a generous layer of cooked sauce into a 9”X12” baking pan.
Spoon in half the ricotta cheese, then layer on 3 lasagna noodles.
Add another layer of sauce, the rest of the ricotta and half of the mozzarella.
Top with the remaining noodles. Add the rest of the sauce, then top with the remaining mozzarella and parmesan cheeses.
Cover lasagna pan with aluminum foil for baking.
Bake covered pan at 350 degrees for 45 min.-1 hour, or until cheese is completely melted and bubbling. You may want to remove the foil during the last 10-15 minutes of baking to allow the cheese to brown.
