Preparation Steps

• In a bowl, toss the beef with cornstarch until evenly coated.
• In a separate bowl, whisk together the soy sauce, brown sugar, water, hoisin sauce, ginger, garlic, and red pepper flakes (if using).
• Heat vegetable oil in a large skillet or wok over high heat. Add the beef and cook, stirring constantly, until browned and cooked through, about 2-3 minutes. Remove the beef from the skillet and set aside.
• Pour the sauce into the skillet and bring to a simmer. Cook for 2-3 minutes, or until the sauce has thickened slightly.
• Add the beef back to the skillet and toss to coat. Cook for another minute to heat through.
• Cook the ramen noodles according to package directions. Drain and divide among bowls.
• Top the ramen noodles with the Mongolian beef and sauce. Garnish with sesame seeds and sliced green onions, if desired.
