Cook ground beef and onion in a large skillet over medium heat, until beef is browned and onion is soft and translucent.
Use a spatula or wooden spoon to break up the ground beef into small crumbles as it cooks.
Drain off any excess fat and discard.
Add Italian seasoning and minced garlic to the skillet. Stir until garlic is fragrant, about 1 minute.
Add the diced tomatoes, chicken broth, cream, and gnocchi to the pan, and stir to combine.
Increase heat to medium high and bring the sauce to a simmer.
Once the sauce is simmering, cover the pan and reduce heat to low. Cook for five minutes or until gnocchi are cooked through.
Uncover pan and stir, letting the sauce simmer over low heat. Cook until sauce reduces slightly and thickens, about 5 more minutes.
Stir in grated Parmesan cheese and season with salt and pepper. Cook until cheese is melted.
To serve, top each serving with a little more shredded Parmesan cheese and a sprinkle of freshly chopped Parsley.
