Bring a large pot of water to a rolling boil over high heat. Add the instant ramen noodles and cook according to the package instructions for about 3 minutes. Drain and set aside.

In a medium bowl, whisk together ¼ cup of soy sauce, 1 tablespoon of brown sugar, and 2 tablespoons of water until dissolved. Set aside.

Heat 1 tablespoon of olive oil in a pan over medium heat. Add minced garlic and white parts of green onions. Sauté for about 1 minute until fragrant.

Pour the soy sauce mixture into the pan and stir well. Allow it to simmer for about 2 minutes.

Add the drained ramen noodles to the pan and toss gently to coat them in the sauce. Simmer for another 2 minutes.

Remove from heat and transfer ramen to a bowl. Garnish with green onion tops, red chili flakes, and sesame seeds before serving.
