Preheat the oven to 180°C (350°F). Place the precooked ramen noodles in the center of a baking dish.
Arrange the carrots, red bell pepper, green bell pepper, red cabbage, and spring onions around the noodles. Sprinkle the garlic and ginger over the vegetables.
Pour the coconut milk and vegetable stock over everything. Bake for 15 to 20 minutes, until the vegetables are tender and the broth is hot.
Remove from the oven and gently stir to combine the noodles with the broth.
Divide into bowls and garnish with sesame seeds, cilantro, and chili oil if using.
