Tools You’ll Need

Tongs or spatula
Mixing bowls
Measuring cups and spoons

Step-by-Step Instructions

Step 1: Prep the Beef
In a bowl, combine thinly sliced beef with 1 tbsp soy sauce, 1 tbsp cornstarch, and 1 tsp sesame oil.
Toss until the beef is evenly coated. Let it marinate while you prepare the other ingredients.
This quick marinade adds flavor and helps the beef brown beautifully.

Step 2: Cook the Noodles
Bring a pot of water to a boil. Cook the noodles according to the package instructions.
Drain and rinse with cold water to stop the cooking process.
Set aside while you finish the stir-fry.

Step 3: Make the Sauce
In a small bowl, whisk together soy sauce, hoisin sauce, brown sugar, oyster sauce, grated ginger, garlic, and beef broth.
In a separate cup, mix 1 tsp cornstarch with 1 tbsp water to make a slurry and set aside.
This will thicken the sauce later for a silky texture.

Step 4: Stir-Fry the Beef
Heat 1 tbsp vegetable oil in a large skillet or wok over medium-high heat.
Add the beef and cook for 2-3 minutes, stirring often, until browned and just cooked through.
Remove beef from the pan and set aside.

Step 5: Cook the Vegetables
In the same skillet, add the white parts of the green onions, carrots, bell peppers, and snap peas.
Stir-fry for 3-4 minutes until slightly tender but still crisp.
Add a splash of water if needed to help steam and soften the vegetables.

Step 6: Add Sauce and Beef
Return the cooked beef to the pan with the vegetables.
Pour in the prepared sauce and bring to a simmer.
Add the cornstarch slurry and stir until the sauce thickens, about 1-2 minutes.

Step 7: Toss in the Noodles
Add the cooked noodles to the skillet.
Use tongs to gently toss everything together until the noodles are fully coated in sauce.
Cook for another 1-2 minutes to warm everything through.

Step 8: Garnish and Serve
Top with the green parts of the sliced green onions and a sprinkle of sesame seeds if using.
Serve hot, straight from the skillet, or plate it up for a beautiful presentation.

Tips for Success
Slice Beef Thinly – This ensures quick cooking and tender results.
Use High Heat – A hot skillet gives you the best sear and stir-fry flavor.
Don’t Overcrowd the Pan – Cook the beef in batches if needed to avoid steaming.
Taste & Adjust – Add more soy sauce for saltiness or a splash of rice vinegar for a tangy twist.
Try Different Noodles – Lo mein, udon, rice noodles, or even fettuccine work well.

Serving Suggestions
Pair with a simple cucumber salad or steamed edamame.
Serve with a side of fresh fruit like pineapple or mango to balance the savory flavors.
Enjoy with green tea or a refreshing lemonade.
