In a small mixing bowl, combine the dark soy sauce, oyster sauce, hoisin sauce, mirin, and chili garlic sauce if using. Whisk together until well blended. Set this aside; it’ll be a vital flavor bomb!

Grab a medium skillet and place it on medium-high heat. Add the neutral oil and sesame oil to the pan. Once heated, toss in the sliced onion and minced garlic. Sauté for about 1.5 minutes, stirring frequently until they just start to change color and release their delicious aroma.

Time to add in the ground beef! Increase the heat slightly and add the beef to the pan. Use a spatula to break it apart as it cooks. You'll want to stir until the beef has turned from pink to a light golden brown, which should take about 3-4 minutes.

Now, pour in your sauce mixture. Stir everything together and let it cook for about 2-3 minutes, or until the sauce thickens and coats the beef. This is where the flavor really develops, and it is pure magic.

Create some space in the skillet by pushing the beef mixture to one side. Pour in the water, giving it a quick stir to deglaze the pan. Then, add the ramen noodles to the water and press them down gently to ensure they get submerged.

Let the noodles sit in the water for about 45 seconds, then turn them to cook the other side for another 30 seconds. As you do this, slowly untangle them with your utensils and mix them with the beef mixture. This helps everything meld together beautifully!

Once the noodles are fully cooked, toss in the bean sprouts. Stir for another minute, allowing them to wilt slightly and the sauce to reduce and coat all the ingredients. The goal is perfectly cooked noodles alongside crunchy sprouts and flavorful beef.

Transfer your delicious creation into bowls. Garnish with thinly sliced green onions and sesame seeds. Enjoy hot!
