About the Ingredients

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

Use any tender cut like flank or ribeye. For a budget option, try skirt steak.

2 tbsp (30ml) soy sauce

Use low-sodium to control salt. Tamari works for gluten-free.

1 tbsp (15ml) oyster sauce

Adds depth. Sub with hoisin or mushroom stir-fry sauce for vegetarian.

1 tsp (5ml) sesame oil

Toasted sesame oil is best. If you only have regular, add a bit more.

1 tbsp (8g) cornstarch

Helps tenderize beef and thicken sauce. Use potato starch as a sub.

2 tbsp (30ml) vegetable oil, divided

Use high smoke point oil like canola or peanut. Avoid olive oil for searing.

1 red bell pepper, sliced into thin strips

Any color works; red is sweetest. Add a poblano for a mild kick.

1 green bell pepper, sliced into thin strips

Green peppers are slightly bitter. Swap with yellow or orange for sweetness.

1 medium onion, thinly sliced

Yellow or white onion. Red onion adds a milder flavor.

3 cloves garlic, minced

Fresh is best. Use 1 tsp garlic powder if in a pinch.

1 tbsp (15ml) fresh ginger, grated

Use a microplane for easy grating. Ground ginger (1/2 tsp) works but less aromatic.

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

Fresh lo mein is ideal. Spaghetti or udon are great subs. Cook al dente.

2 tbsp (30ml) soy sauce (for sauce)

Use low-sodium to control salt. Tamari works for gluten-free.

1 tbsp (15ml) oyster sauce (for sauce)

Adds depth. Sub with hoisin or mushroom stir-fry sauce for vegetarian.

1 tsp (5g) sugar

Balances saltiness. Use honey or maple syrup for a twist.

1/4 cup (60ml) beef broth (or water)

Adds liquid for sauce. Chicken or vegetable broth also fine.

1 tsp (5ml) chili garlic sauce (optional)

For heat. Use sriracha or red pepper flakes to taste.

2 green onions, sliced for garnish

Adds freshness. Chives work too.

Tips & Tricks

• Slice the beef thinly against the grain for tenderness. Freeze the steak for 20 minutes to make slicing easier.
• Cook the noodles just under al dente so they don't become mushy when stir-fried.
• Have all ingredients prepped and ready before you start cooking; stir-frying goes fast.

Step-by-Step Instructions

1. Marinate the Beef

In a bowl, combine beef, 2 tbsp soy sauce, 1 tbsp oyster sauce, sesame oil, and cornstarch. Mix well and let sit for 10 minutes while you prep veggies.

2. Cook the Noodles

Bring a pot of water to a boil (212°F/100°C). Cook noodles according to package instructions until just al dente. Drain, rinse with cold water, and toss with a little oil to prevent sticking.

3. Make the Sauce

In a small bowl, whisk together 2 tbsp soy sauce, 1 tbsp oyster sauce, sugar, beef broth, and chili garlic sauce if using. Set aside.

4. Sear the Beef

Heat 1 tbsp vegetable oil in a wok or large skillet over high heat (400°F/204°C). Add beef in a single layer and sear for 2-3 minutes until browned on one side but not fully cooked. Remove beef and set aside.

5. Stir-Fry the Vegetables

Add remaining 1 tbsp oil to the pan. Add bell peppers and onion, stir-fry over high heat for 3-4 minutes until crisp-tender and slightly charred at edges. Add garlic and ginger, cook for 30 seconds until fragrant.

6. Combine Everything

Return the beef to the pan, add the cooked noodles, and pour the sauce over. Toss everything together over high heat for 1-2 minutes until the sauce coats everything and is bubbling.

7. Garnish and Serve

Remove from heat, sprinkle with green onions, and serve immediately. Enjoy your delicious pepper steak noodles!

Delicious Variations

Vegetarian

Replace beef with tofu or tempeh, and use mushroom soy sauce instead of oyster sauce.

Spicy

Add more chili garlic sauce or a drizzle of sriracha before serving.

Add Veggies

Throw in broccoli, snap peas, or carrots for extra crunch and color.
