How to Make Beef and Onion Stir Fry Recipe
Step 1: Marinate the Beef
Start by mixing the thinly sliced flank steak with soy sauce, oyster sauce, hoisin sauce, and cornstarch in a medium bowl. This combination tenderizes the meat and builds a wonderful savory base flavor. Let the beef marinate for about 15 minutes so all those gorgeous flavors sink in deeply, making every bite more delicious.
Step 2: Cook the Beef
Heat your vegetable oil in a large skillet or wok over medium-high heat — this high temperature is perfect for quick searing. Add the marinated beef in a single layer and stir-fry for 2 to 3 minutes until it’s beautifully browned but still juicy. Remove it from the skillet and set aside to keep the beef tender and prevent overcooking.
Step 3: Sauté the Onions, Garlic, and Ginger
In the same skillet, toss in the thinly sliced onions and stir-fry for about 3 minutes until they soften and start to caramelize just enough to turn sweet and fragrant. Then, add the minced garlic and freshly grated ginger for a minute more — this step ensures their flavors blossom perfectly without burning.
Step 4: Combine and Finish Cooking
Return the cooked beef to the skillet with the onions, garlic, and ginger. Pour in 2 tablespoons of water to loosen the sauce and help everything meld together. Stir and cook everything for an additional 2 to 3 minutes, during which the sauce thickens, the beef finishes cooking, and all the flavors marry into a delightful harmony.
Step 5: Final Touches
Off the heat, drizzle the dish with aromatic sesame oil for that classic nutty finish. Taste and season with salt and black pepper as needed. Garnish with sliced green onions for a fresh, crisp bite and a splash of vibrant green color before serving.
How to Serve Beef and Onion Stir Fry Recipe

Garnishes
The simple addition of sliced green onions brings a beautifully fresh crunch that contrasts the tender beef and softened onions. You can also sprinkle toasted sesame seeds or a few red pepper flakes if you want a little heat and extra texture.
Side Dishes
This Beef and Onion Stir Fry Recipe pairs wonderfully with steamed jasmine rice, which soaks up the flavorful sauce perfectly. For a low-carb option, serve it alongside cauliflower rice or even a bed of sautéed greens like bok choy or spinach for a vibrant, nutritious meal.
Creative Ways to Present
For a fun and casual gathering, serve the stir fry with lettuce leaves for DIY wraps that add crisp contrast. Or, place it on top of cooked noodles for a quick beef noodle bowl that’s both comforting and easy to customize with your favorite toppings.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer the leftover beef and onion stir fry to an airtight container and store in the refrigerator for up to 3 days. The flavors deepen nicely, making it an excellent make-ahead meal for busy weekdays.
Freezing
This Beef and Onion Stir Fry Recipe freezes well in individual portions. Pack leftovers into freezer-safe containers or bags, removing as much air as possible. It can be frozen for up to 2 months without losing flavor or texture.
Reheating
Reheat leftovers in a skillet over medium heat to retain the beef’s tenderness and prevent the onions from losing their texture. Alternatively, microwave on medium power in short intervals, stirring between each, until warmed through.
FAQs
Can I use a different cut of beef for this stir fry?
Absolutely! While flank steak is ideal for its tenderness and quick cooking, you can also use sirloin or skirt steak as long as you slice it thinly against the grain to keep it tender.
Is this recipe spicy, and can I make it spicier?
The base recipe is mild and highlights savory and sweet flavors, but you can easily add crushed red pepper flakes, chili oil, or fresh chili slices during cooking if you want a spicy kick.
Can I add more vegetables to the stir fry?
Definitely! Bell peppers, snap peas, or even shredded carrots make wonderful additions, adding color, crunch, and nutritional value to the dish.
How do I get the beef tender and not chewy?
Marinating the beef with the sauce and cornstarch for 15 minutes helps tenderize it and protects it during cooking. Also, make sure to slice the beef thinly against the grain and cook it quickly over high heat to avoid toughness.
What can I substitute for oyster sauce or hoisin sauce?
If you don’t have oyster or hoisin sauce, you can substitute with a mix of soy sauce and a little honey or brown sugar for sweetness, though the depth of flavor will be slightly different but still delicious.
