Blanch the bok choy and set aside.
Add the ground beef to a pan, smash it down to get a nice crust, and add the spices, a little oil, fish sauce, and soy sauce. Stir together and remove from the pan.
In the same pan, sauté the green onion whites, garlic, and grated ginger. Add the tomato paste and red curry paste, let them caramelize a bit, then stir in the rest of the spices to bloom.
Pour in the coconut milk and whisk to blend everything smoothly. Add a splash of chicken broth to thin it out.
Boil the ramen noodles, then add them directly to the sauce. Stir in the crispy ground beef and lime juice.
Serve with the blanched bok choy, and optional garnishes like green onion tops, chili oil, and sesame seeds.
