Ingredients You’ll Need
The beauty of this stir fry is that it uses simple, everyday ingredients, but the end result tastes like something you’d order from a high-end Asian restaurant.
- 1 pound flank steak, thinly sliced against the grain – Flank steak is ideal for stir frying because it’s lean, flavorful, and tender when sliced properly.
- 2 tablespoons soy sauce – Adds depth and that classic umami flavor.
- 1 tablespoon cornstarch – Helps tenderize the beef and creates a silky sauce.
- 2 tablespoons vegetable oil – For stir-frying at high heat.
- 1 large onion, sliced – The star vegetable of this dish, sweet and slightly caramelized when cooked.
- 2 cloves garlic, minced – Provides that signature Chinese stir-fry aroma.
- 1 bell pepper, sliced (any color) – Adds crunch, sweetness, and vibrant color.
- 1 teaspoon ginger, minced – A warm, spicy undertone that balances the dish.
- 1/4 cup beef broth – Helps create the sauce base.
- 1 tablespoon oyster sauce – Brings rich, savory-sweet flavor.
- 1 tablespoon sesame oil – Adds nutty fragrance and depth at the end.
- Salt and pepper to taste – For seasoning balance.
- Cooked rice or noodles – The perfect base for serving.
Step-by-Step Instructions
1. Marinate the Beef
Start by combining the sliced flank steak with soy sauce and cornstarch. This step is essential: the soy sauce adds flavor, while the cornstarch coats the beef, keeping it tender and allowing it to develop that glossy stir-fry texture. Let it sit for 15 minutes while you prep the vegetables.
2. Sear the Beef
Heat 1 tablespoon of oil in a wok or large skillet over medium-high heat. Spread the beef in a single layer and let it sear without moving it too much. After 2-3 minutes, flip and finish cooking until browned. Remove the beef from the pan—this keeps it from overcooking.
3. Stir Fry the Vegetables
In the same skillet, add the remaining tablespoon of oil. Toss in the onion and bell pepper, stir-frying until they soften slightly, about 3-4 minutes.
4. Add Aromatics
Add garlic and ginger, stirring quickly for 1 minute until fragrant. This step is what gives the stir fry its iconic depth of flavor.
5. Bring It All Together
Return the beef to the skillet, then pour in the beef broth and oyster sauce. Stir everything together and let the sauce thicken slightly, about 2-3 minutes.
6. Finish with Sesame Oil
Drizzle sesame oil over the stir fry, season with salt and pepper, and toss everything until well coated.
7. Serve and Enjoy
Serve hot over fluffy rice or noodles. Garnish with sesame seeds or chopped green onions for an extra layer of flavor and presentation.

Tips for the Perfect Stir Fry
- Slice Against the Grain: Cutting the beef against the grain ensures tenderness.
- Don’t Overcrowd the Pan: Cook beef in a single layer so it sears instead of steaming.
- High Heat is Key: A hot skillet helps achieve that restaurant-style stir fry texture.
- Adjust Sauce Consistency: If the sauce feels too thick, add a splash more broth. Too thin? Simmer a bit longer or add a touch more cornstarch slurry.
- Prep Everything in Advance: Stir fry moves fast—have all your ingredients ready before you start cooking.
Variations to Try
- Spicy Kick – Add sliced jalapeños, red chili flakes, or a drizzle of chili oil.
- Different Proteins – Swap beef for chicken, shrimp, or tofu.
- Vegetable Boost – Add broccoli, snow peas, or mushrooms for more variety.
- Low-Carb Option – Serve over cauliflower rice or zucchini noodles.
- Gluten-Free Adaptation – Use tamari instead of soy sauce and ensure your oyster sauce is gluten-free.
Serving Suggestions
This stir fry is a star on its own, but pairing it with the right sides can elevate the meal even more:
- Steamed Jasmine Rice – A classic choice that soaks up the flavorful sauce.
- Garlic Fried Rice – For an extra punch of flavor.
- Lo Mein or Rice Noodles – Tossed lightly in soy sauce and sesame oil.
- Asian-Inspired Side Dishes – Try it with egg rolls, dumplings, or a light cucumber salad.
The Story Behind Beef and Onion Stir Fry
Stir frying is one of the most beloved Chinese cooking techniques, dating back thousands of years. It’s all about quick cooking over high heat, preserving both the flavor and nutrition of each ingredient.
Beef and onion stir fry is a classic comfort dish in many Chinese households. The onions become sweet and tender, balancing the savory richness of the beef. This combination has stood the test of time because it’s satisfying, affordable, and versatile. It’s the kind of dish you’d find at a casual dinner table just as easily as at a bustling restaurant.
Making this dish at home allows you to honor that tradition while also making it your own with personal touches.
Common Mistakes to Avoid
- Overcooking the Beef: Since it’s sliced thin, beef cooks quickly. Remove it early to avoid toughness.
- Skipping the Marinade: Cornstarch and soy sauce are essential for flavor and texture—don’t rush this step.
- Using Low Heat: Stir fry needs high heat to properly sear and bring flavors together.
- Overcrowding Vegetables: If your pan is too full, the vegetables steam instead of getting that light char.
Make Ahead and Storage Tips
- Prep Ahead: Slice beef and veggies the night before. Store separately in airtight containers.
- Leftovers: Store cooked stir fry in the fridge for up to 3 days. Reheat quickly in a hot skillet to preserve texture.
- Freezer-Friendly: Marinated raw beef can be frozen for up to 2 months. Thaw overnight before cooking.
Pairing Drinks with Stir Fry
If you want to make your meal feel more like a restaurant experience, try pairing it with a refreshing drink:
- Green Tea: Light and cleansing.
- Citrus Sparkling Water: Refreshes the palate.
- Light Beer or Sake: Complements the umami richness of the dish.
- Homemade Lemon Iced Tea: Sweet and cooling against the savory stir fry.
