To a large pot, add 1 tablespoon of sesame oil and heat over medium high heat. Season the chicken thigh with salt, then add it to the pot. Cook for 5 minutes per side, or until the internal temperature reaches 165℉. Remove the chicken from the pot to a cutting board and allow it to rest.
While the chicken is cooking, bring a medium pot of water to a boil and cook the noodles according to the instructions on the packet. If your noodles came with a seasoning packet, you can discard the packet. Once the noodles are done cooking, drain them and rinse with cool water.
Reduce the heat to medium and add the remaining 1 tablespoon sesame oil, minced garlic and grated ginger to the pot and stir. Cook for 2-3 minutes, or until the garlic becomes fragrant.
Add the sliced mushrooms to the pot and stir. Then, carefully add the broth. Stir to combine.
Bring the broth and veggies to a simmer, then remove from the heat. While the broth is simmering, slice your chicken.
Add your cooked noodles to a bowl, then carefully pour the broth with mushrooms, ginger, and garlic over top. Add your sliced chicken and garnish with green onions, a sprinkle of black sesame seeds, and a soft-boiled egg.
Serve and enjoy!
