Step 1: In a large skillet or pot, cook the ground beef over medium-high heat, breaking it up with a spatula, until it’s browned and cooked through, about 5-7 minutes. Drain any excess fat.

Step 2: Add the beef broth, soy sauce, brown sugar, garlic, ginger, and red pepper flakes (if using) to the skillet. Bring the mixture to a boil.

Step 3: Add the ramen noodles to the skillet and cook for 2-3 minutes, or until the noodles are tender. Stir frequently to prevent sticking.

Step 4: Season with salt and pepper to taste.

Step 5: Serve the ramen and ground beef hot, garnished with chopped green onions if desired.
