Heat a stock pot or Dutch oven over medium heat. Once hot, lightly grease and add chicken or pork (or vegetarian alternative). Cook for 4 to 5 minutes, using a wooden spoon to break meat into small pieces. Transfer meat to a bowl and set aside.

Add oil to pan, along with mushrooms. Cook 5 minutes, until golden and tender. Stir in shallots, garlic, and ginger; cook 2 to 3 more minutes, until aromatic.

Stir in miso paste, soy sauce, rice vinegar, and hot chili oil. Add 6 cups of broth and bring mixture to a boil. If you prefer a brothier ramen, add an additional 1 to 2 cups of broth at this time. Lower heat and very gently simmer over medium-low for 20 minutes.

Bring broth back to a boil, and add noodles. Cook until noodles are al dente, about 3 minutes, or according to package instructions. Stir in cooked meat and corn.

Ladle ramen into bowls, and top each serving with 1 soft-boiled egg, a handful of green onions, and toasted sesame seeds. For more spice, drizzle extra chili oil overtop.
