Heat the vegetable oil in a large skillet over medium-high heat. Add the ground beef and break it into small pieces with a wooden spoon or spatula. Cook until the beef is browned and cooked through. Drain any excess grease if needed.
Reduce the heat to medium. Stir in the garlic and ginger and cook for about 30 seconds, just until fragrant.
Add the honey, soy sauce, hoisin sauce and beef broth. Stir everything together and let the sauce gently simmer for 3 to 4 minutes.
In a small bowl, whisk the cornstarch and cold water together until smooth. Slowly pour the slurry into the skillet while stirring. Allow the sauce to simmer for another 2 to 3 minutes, or until it thickens slightly.
Add the cooked spaghetti to the skillet and toss until the noodles are evenly coated in the sauce. Serve warm and enjoy!
