It’s the perfect homemade alternative to takeout, offering a satisfying meal that’s easy, customizable, and ready in minutes.

Ingredients

Scale
  • 1 lb flank steak or sirloin, thinly sliced against the grain
  • 1/2 cup low-sodium soy sauce
  • 1/4 cup brown sugar
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1 tablespoon cornstarch
  • 2 tablespoons vegetable oil
  • 8 oz lo mein noodles or spaghetti, cooked and drained
  • 3–4 stalks green onions, sliced
  • 1 teaspoon red pepper flakes (optional)

Instructions

  1. Slice the beef thinly against the grain. Toss with 1 tablespoon cornstarch and let rest for 10 minutes.
  2. Cook the noodles according to package directions until just al dente, then drain and set aside.
  3. In a small bowl, whisk together soy sauce, brown sugar, garlic, ginger, and 1 tablespoon water mixed with a little cornstarch to make a slurry.
  4. Heat oil in a large skillet or wok over medium-high heat. Sear the beef in batches until browned, then remove and set aside.
  5. Pour the sauce mixture into the same pan and simmer for 1–2 minutes until thickened.
  6. Add the cooked noodles and beef to the skillet, tossing to coat evenly in the sauce.
  7. Top with sliced green onions and red pepper flakes, then serve hot.

Notes

  • Slice beef thinly for tenderness and quick cooking.
  • Use tamari or coconut aminos for a gluten-free version.
  • Add vegetables like broccoli, bell peppers, or snap peas for extra crunch and nutrition.
  • Leftovers can be stored in the refrigerator for 3–4 days.
  • Reheat gently on the stovetop with a splash of water to maintain texture.
