In a large pot, heat sesame oil over medium heat. Add minced garlic and ginger and sauté for 1–2 minutes until fragrant.
Pour in the chicken broth, soy sauce, rice vinegar, hoisin (if using), and sriracha. Stir to combine and bring to a simmer. Let the broth cook for 10–15 minutes to deepen the flavor.
Stir in the cooked chicken and your choice of vegetables like carrots and spinach. Simmer for another 5 minutes until everything is heated through and the veggies are just tender.
In a separate pot, boil the ramen noodles according to the package directions (usually 2–3 minutes). Drain and rinse under warm water to remove excess starch.
Divide the cooked noodles among serving bowls. Ladle the hot broth and chicken mixture over the noodles. Top with boiled eggs, green onions, sesame seeds, and any additional garnishes you like.
