Can I use a different type of noodle?
Yes. Ramen noodles, wheat noodles, or even spaghetti work well; adjust cooking time based on the noodle type.
How spicy is this dish?
The heat level depends on the fresh red chili. Start with half a chili, taste, and add more if you prefer it spicier.
Can I make this ahead?
Cook the beef sauce ahead and store in the fridge for up to 3 days. Cook noodles fresh and combine just before serving for best texture.
What can I substitute for oyster sauce?
Use hoisin sauce or soy sauce for a similar umami depth, though flavor will shift slightly.
How do I know when the beef is cooked through?
Ground beef is done when no pink remains and it reaches 160°F internal temperature; it will crumble easily when stirred.
