1-First, gather and prepare all ingredients, slicing the 1 pound of flank steak thinly and mixing the marinade with 4 tablespoons of Korean chili paste, 2 tablespoons of thinly sliced green onions, 2 tablespoons of soy sauce, 2 tablespoons of rice vinegar, 4 teaspoons of minced garlic, 1 teaspoon of ground ginger, 1 tablespoon of sesame oil, and 4 teaspoons of sugar. Marinate the steak in half this sauce for at least 30 minutes or overnight to let the flavors soak in deeply. This step is crucial for that tender, flavorful result in your “spicy Korean beef ramen recipe”.

2-Second, heat 2 tablespoons of oil in a pan over medium-high heat and sear the marinated steak for 5-8 minutes on each side until it’s nicely browned. Let the steak rest for a few minutes to keep it juicy. Third, in the same pan, cook the thinly sliced half a white onion and ½ cup of sliced mushrooms until they soften, adding aroma and texture.

3-Fourth, add the 2 packages of beef ramen noodles along with their seasoning and 1 ½ cups of water to the pan, then pour in the reserved marinade.

4-Fifth, slice the rested steak thinly across the grain and stir it back into the pan with the sauce for even coating. Finally, garnish with additional green onions and serve immediately for the best taste.
