Easy Pepper Steak Noodles – 30-Minute One-Pan Dinner

When I was a kid, my mom would make pepper steak on nights when we needed something hearty and fast. The smell of soy sauce and garlic sizzling in the pan still takes me back to our tiny kitchen. Now I've turned that classic into a noodle dish that my own family begs for on busy weeknights.

This Pepper Steak Noodles recipe is my weeknight superhero. It's a one-pan wonder that comes together in about 30 minutes, using simple ingredients you probably already have. The beef gets seared until caramelized, the peppers keep a little crunch, and the noodles soak up all that savory sauce. It's comfort food with a kick of freshness from the bell peppers.

I love that this dish is flexible. You can swap the protein, add more veggies, or turn up the heat with extra chili flakes. It's forgiving, fast, and always satisfying. Let's get cooking!

About the Ingredients

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

Slicing against the grain ensures tenderness. If you don't have flank steak, use sirloin or ribeye; freeze for 20 minutes to make slicing easier.

2 tablespoons (30ml) soy sauce, divided

Use low-sodium soy sauce if you prefer less salt. Tamari or coconut aminos work as gluten-free swaps.

1 tablespoon (15ml) cornstarch

This helps tenderize the beef and thicken the sauce. You can use potato starch or arrowroot powder as substitutes.

1 teaspoon (5ml) sesame oil

Adds a nutty aroma. If you don't have it, use a neutral oil and add a few drops of toasted sesame seeds for flavor.

2 tablespoons (30ml) vegetable oil, divided

For searing the beef and stir-frying. Grapeseed or canola oil are great high-heat options.

1 red bell pepper, thinly sliced

Adds sweetness and color. You can use any color bell pepper; for a spicier kick, try a poblano or banana pepper.

1 green bell pepper, thinly sliced

Provides a classic pepper steak flavor. If you're not a fan, use another red or yellow pepper.

1 medium onion, thinly sliced

Yellow or white onion works best. For a milder flavor, use a sweet onion like Vidalia.

3 cloves garlic, minced

Fresh garlic is best. In a pinch, use 1 teaspoon of garlic powder, but the fresh flavor is worth it.

1 tablespoon (15ml) freshly grated ginger

Adds warmth and zing. You can use 1 teaspoon of ground ginger if fresh isn't available, but fresh is better.

1/2 cup (120ml) beef broth

Use low-sodium to control salt. Chicken or vegetable broth also work.

2 tablespoons (30ml) oyster sauce

Gives deep umami. For a vegetarian version, use mushroom oyster sauce or hoisin.

1 tablespoon (15ml) rice vinegar

Adds a subtle tang. Apple cider vinegar can be used as a substitute.

1 teaspoon (5g) brown sugar

Balances the saltiness. Honey or maple syrup are good alternatives.

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

Lo mein noodles are traditional, but spaghetti or linguine work perfectly. Cook according to package directions.

2 green onions, sliced (for garnish)

Adds freshness and color. Chives or cilantro are also nice.

Tips & Tricks

• Slice the beef thinly and against the grain for maximum tenderness. Freezing the steak for 20 minutes makes slicing easier.
• Cook the noodles just shy of al dente, as they will finish cooking in the sauce. Drain and toss with a little oil to prevent sticking.
• Don't overcrowd the pan when searing the beef. Work in batches if needed to get a nice brown crust instead of steaming.

Step-by-Step Instructions

1. Marinate the Beef

In a bowl, combine the sliced beef, 1 tablespoon soy sauce, cornstarch, and sesame oil. Mix well and let sit for 10 minutes while you prep the veggies. This tenderizes the beef and adds flavor.

2. Cook the Noodles

Bring a pot of salted water to a boil. Cook the noodles according to package directions until just al dente (about 4-5 minutes). Drain, rinse with cold water, and toss with a little oil to prevent sticking.

3. Make the Sauce

In a small bowl, whisk together the remaining 1 tablespoon soy sauce, beef broth, oyster sauce, rice vinegar, and brown sugar. Set aside.

4. Sear the Beef

Heat 1 tablespoon vegetable oil in a large skillet or wok over high heat (about 400°F/200°C). Add the beef in a single layer and cook without stirring for 1-2 minutes until browned on one side. Flip and cook for another minute until just cooked through. Transfer to a plate.

5. Stir-Fry the Veggies

In the same skillet, add the remaining 1 tablespoon oil. Add the bell peppers and onion. Stir-fry over high heat for 3-4 minutes until the edges are slightly charred and the veggies are crisp-tender. Add the garlic and ginger, and cook for 30 seconds until fragrant.

6. Combine Everything

Pour the sauce into the skillet. Bring to a simmer and let it bubble for 1-2 minutes until slightly thickened. Add the beef back along with the cooked noodles. Toss everything together to coat evenly, and cook for another 1-2 minutes until heated through.

7. Garnish and Serve

Remove from heat. Sprinkle with sliced green onions and serve hot. Enjoy!

Delicious Variations
