For the Sauce:

• ⅓ cup low-sodium soy sauce
• 2 tablespoons oyster sauce (optional, or use hoisin sauce)
• 1 tablespoon brown sugar
• 1 tablespoon cornstarch
• 2 teaspoons sesame oil
• ¼ cup beef broth or water

For the Stir Fry:

• 1 tablespoon grated ginger
• 1 red bell pepper, sliced
• 1 cup shredded carrots
• 2 cups broccoli florets
• 8 ounces lo mein noodles or spaghetti, cooked and drained
• 2 green onions, chopped

Step-by-Step Instructions

1. Prepare the beef: In a small bowl, mix sliced beef with soy sauce, cornstarch, and sesame oil. Let it marinate for 10–15 minutes while preparing other ingredients.
2. Mix the sauce: In another bowl, whisk together soy sauce, oyster sauce, brown sugar, cornstarch, sesame oil, and beef broth until smooth. Set aside.
3. Cook the beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef and stir-fry for 2–3 minutes until browned. Remove from the pan and set aside.
4. Cook the vegetables: In the same pan, add remaining oil, garlic, and ginger. Sauté for 30 seconds. Add bell peppers, carrots, and broccoli. Stir-fry for 3–4 minutes until slightly tender.
5. Combine everything: Return the cooked beef to the pan, add the cooked noodles, and pour in the sauce. Toss everything together until evenly coated and heated through.
6. Serve: Garnish with chopped green onions and a sprinkle of sesame seeds if desired. Serve hot.

Tips & Variations

• Add more veggies: Try snow peas, mushrooms, or cabbage for extra color and crunch.
• Make it spicy: Stir in a teaspoon of chili flakes or sriracha for heat.
• Noodle options: Use ramen, udon, or even rice noodles if you don’t have lo mein.
• Vegetarian version: Substitute beef with tofu or just use vegetables.
• Meal prep tip: Store noodles and sauce separately to keep texture perfect.

Storage & Freezing

• Refrigerate: Store leftovers in an airtight container for up to 4 days.
• Freeze: Freeze for up to 2 months. Thaw in the fridge overnight before reheating.
• Reheat: Reheat gently in a skillet with a splash of water or soy sauce to revive the flavor.

Serving & Pairing Ideas

• Serve with spring rolls or Asian cucumber salad for a balanced meal.
• Pair with a light miso soup or steamed dumplings.
• Garnish with fresh cilantro, lime wedges, or sesame seeds for brightness.
