In small bowl, whisk together chicken broth, fish sauce, sesame oil, sugar, Sriracha and soy sauce.
On a sheet pan, lay out a sheet of foil, about 20 by 15 inches. Break ramen noodles and lay evenly in middle of foil. Top with mushrooms, green onions and shrimp. Slightly lift sides of foil to create a bowl-like shape. Pour liquid all over noodles. Crimp foil together edges to seal. Make sure not to tear and release any liquid. Bake for 15 to 20 minutes.
