Make the Spicy Gochugaru Oil: You will need about 2 tsp for the bowl. Heat neutral oil to 350ºF. Pour the hot oil over the Gochugaru in a heatproof bowl. Stir and let cool completely.
Cube the smoked pork belly. If using, quickly sear or torch the pork belly cubes to crisp the edges. Slice the egg in half. Chop the green onions.
In a saucepan, bring the pork bone broth to a boil. Add the Shin Ramen noodle block and the packet of Shin Ramen seasoning powder.
Boil for 3-4 minutes until the noodles are al dente.
Pour 1-2 teaspoons of Spicy Gochugaru Oil into the bottom of your serving bowl.
Pour the hot noodles and broth directly into the serving bowl over the Gochugaru Oil.
Gently arrange the smoked pork belly cubes and the egg halves on top of the noodles. Garnish with the chopped green onion, sesame seeds, and chili pepper. Serve immediately.
