Finely chop the garlic, slice the mushrooms, and prepare the green onions so everything is ready before the cooking begins.
Melt butter with sesame oil in a medium saucepan over medium heat, then sauté garlic and mushrooms until fragrant and lightly softened.
Pour in the broth and soy sauce, bringing the mixture to a gentle simmer to keep the flavors smooth and balanced.
Slowly stir in the milk or cream, letting it blend into the broth until the color turns rich and creamy without boiling.
Add the ramen noodles directly into the pot and cook for 2–3 minutes, stirring so they soften evenly and absorb the flavor.
Taste the broth and adjust with a little salt, pepper, or extra soy sauce to create a warm, savory, comforting balance.
Ladle the ramen into a bowl and finish with a soft-boiled egg, green onions, or chili flakes for color and extra flavor.
