Heat a large skillet over medium-high heat. Add the ground beef, onion and garlic and cook until the beef is cooked through, breaking up the beef as it cooks.
Add in the tomato sauce, diced tomatoes, sugar, oregano, basil, salt and pepper. Bring to a boil, then reduce the heat and simmer for 15-20 minutes.
Meanwhile, bring a large pot of salted water to a boil. Add the gnocchi and cook until the gnocchi rises to the surface of the water. Remove with a slotted spoon.
Add the cooked gnocchi to the meat sauce and stir to combine. Serve topped with freshly grated parmesan cheese and shredded basil, if desired.
