Step 1

Whisk soy sauce, sesame oil, brown sugar, rice vinegar, chili garlic sauce, and ginger together in a small bowl. Add peanut butter, whisking until well combined, and set aside.

Step 2

Bring 4 cups of water to a boil in a pot. Discard the flavor packet and add ramen noodles to the boiling water. Cook until noodles are tender, 4 to 5 minutes. Drain noodles, reserving some of the noodle water in case you need to thin out the sauce later.

Step 3

Pour sauce over ramen noodles, tossing until well coated. If sauce is too thick, thin out with a small amount of the reserved noodle water until you reach your desired consistency. Your hot noodles will soak up the sauce. Garnish with peanuts and green onion, and serve.
