What is Spicy Miso Ramen?

Spicy Miso Ramen is a variation of traditional miso ramen enhanced with Japanese chili paste, garlic, ginger, and spicy seasonings. Unlike soy sauce-based or salt-based ramen, the broth is thicker, creamier, and more robust thanks to fermented miso paste.

The soup combines:

  • White and red miso paste
  • Chicken or pork broth
  • Garlic
  • Ginger
  • Doubanjiang (chili bean paste)
  • Sesame oil
  • Chili oil
  • Fresh ramen noodles

The result is a comforting bowl packed with layers of spicy, savory, and slightly sweet flavors.
