About the Ingredients

8 oz (225g) flank steak or sirloin, thinly sliced against the grain

Thin slicing ensures tenderness. Substitute with chicken breast or firm tofu for a different protein.

2 tablespoons (30ml) soy sauce (or tamari for gluten-free)

Soy sauce adds saltiness and umami. Tamari is a great gluten-free alternative.

1 tablespoon (15ml) cornstarch

Cornstarch helps tenderize the beef and thickens the sauce. Use potato starch if needed.

1 teaspoon (5ml) sesame oil

Sesame oil adds a nutty aroma. Toasted sesame oil is more intense; use half if you prefer.

2 tablespoons (30ml) vegetable oil, divided

For searing the beef and stir-frying. Use any neutral oil like canola or grapeseed.

1 red bell pepper, thinly sliced

Adds sweetness and color. Use any color you like—orange or yellow work well.

1 green bell pepper, thinly sliced

Green peppers are slightly more bitter, balancing the sweetness. Substitute with poblano for a mild kick.

1 medium onion, thinly sliced

Adds savory depth. Use yellow or sweet onion.

2 cloves garlic, minced

Fresh garlic is best. In a pinch, use 1/2 teaspoon garlic powder.

1 tablespoon (15ml) fresh ginger, grated

Ginger adds warmth and zing. Use 1 teaspoon ground ginger if you don't have fresh.

1/2 cup (120ml) beef broth (or chicken/vegetable broth)

Adds liquid for the sauce. Low-sodium is best to control salt.

2 tablespoons (30ml) oyster sauce (or hoisin for vegetarian)

Oyster sauce gives a rich, savory flavor. Hoisin adds sweetness and works for vegans.

1 teaspoon (5ml) rice vinegar

Adds a tangy brightness. Substitute with apple cider vinegar.

1 teaspoon (5g) brown sugar (optional)

Balances the saltiness. Omit if you prefer less sweet.

8 oz (225g) dried lo mein noodles or spaghetti

Lo mein noodles are ideal, but spaghetti or fettuccine work in a pinch. Cook according to package.

2 green onions, sliced (for garnish)

Adds freshness and color. Optional but recommended.

Tips & Tricks

• Slice the beef thinly against the grain for maximum tenderness. Freeze the steak for 15 minutes to make slicing easier.
• Prep all ingredients before you start cooking—stir-frying goes fast.
• Don't overcrowd the pan when searing the beef; work in batches if needed to get a good sear.
• Taste the sauce before adding the noodles and adjust seasoning—soy sauces vary in saltiness.

Step-by-Step Instructions

1. Marinate the Beef

In a bowl, combine the sliced beef, soy sauce, cornstarch, and sesame oil. Mix well and let sit for 10 minutes while you prep the veggies and noodles.

2. Cook the Noodles

Bring a pot of water to a boil. Cook the noodles according to package instructions until al dente. Drain, rinse with cold water to stop cooking, and set aside.

3. Make the Sauce

In a small bowl, whisk together the beef broth, oyster sauce, rice vinegar, and brown sugar (if using). Set aside.

4. Sear the Beef

Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat (about 400°F/200°C). Add the beef in a single layer and sear for 2-3 minutes per side until browned. Remove and set aside.

5. Stir-Fry the Veggies

Add the remaining 1 tablespoon of oil to the same skillet. Add the bell peppers and onion. Stir-fry over high heat for 4-5 minutes until crisp-tender and slightly charred at the edges. Add the garlic and ginger, and cook for 30 seconds until fragrant.

6. Combine Everything

Return the beef to the skillet. Pour in the sauce and bring to a simmer. Cook for 2-3 minutes until the sauce thickens slightly. Add the cooked noodles and toss to coat everything evenly.

7. Finish and Serve

Cook for another 2 minutes until the noodles are heated through. Garnish with green onions and serve immediately.

Delicious Variations

Chicken Pepper Noodles

Swap the beef for thinly sliced chicken breast and use chicken broth.

Spicy Szechuan Style

Add 1-2 teaspoons of chili garlic sauce or sriracha to the sauce.

Vegetarian Delight

Use tofu or tempeh, replace oyster sauce with hoisin, and use vegetable broth.
