Chili flakes or sesame seeds, for serving (optional)
Method
Heat a large pot over medium-high heat. Once the pot is hot, add the pork and cook, undisturbed, 4-5 minutes, or until the bottom is crispy. Continue to cook, breaking up the meat up with a wooden spoon, until browned and cooked through, 6 to 8 minutes more. Transfer the pork to a plate. Drain off any excess fat. Add the sesame oil to the same pot. Once the oil is glistening, add the garlic and ginger and cook, stirring, until fragrant, about 1 minute.
Add the red curry paste and yellow curry powder and cook, stirring, until fragrant, 1 minute. Add the coconut milk, chicken stock, soy sauce, mushrooms, bok choy, green onions, and salt and bring to a boil over high heat. Reduce the heat to medium-high and cook, stirring occasionally until the bok choy is tender, 3 to 4 minutes. Add the ramen noodles and pork and cook, stirring occasionally, until the noodles are tender, about 3 minutes.
To serve, divide the ramen among 4 bowls. Top with the egg halves and sprinkle with the chili flakes and sesame seeds, if using.
