In a large pot, heat the sesame oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Stir in the chili paste and grated ginger, cooking for another 30 seconds to combine the flavors.
Add the vegetable broth to the pot and bring it to a boil.
Once boiling, add the sliced shiitake mushrooms and let it simmer for about 5 minutes, allowing the mushrooms to soften.
Meanwhile, cook the ramen noodles in a separate pot according to package instructions. Drain and set aside.
After the broth has simmered, stir in soy sauce and baby spinach. Allow the spinach to wilt into the broth for about 2 minutes.
Add the cooked ramen noodles to the broth mixture, tossing to combine and heat through.
Divide the spicy garlic ramen noodles into bowls, topping each with chopped green onions and a sprinkle of sesame seeds. For extra richness, add a soft-boiled egg on top if desired.
Notes
Adjust the chili paste for desired spice level. Soft-boiled eggs are optional but recommended for richness.
