Ingredients

For the stir fry:

• 1 pound flank steak or sirloin, thinly sliced against the grain
• 1 large yellow onion, sliced into thin wedges
• 2 cups broccoli florets
• 1 red bell pepper, sliced into strips
• 1 carrot, julienned or thinly sliced
• 2 tablespoons vegetable oil, divided

For the sauce:

• 1/4 cup soy sauce (low-sodium recommended)
• 2 tablespoons oyster sauce
• 1 tablespoon sesame oil
• 2 teaspoons cornstarch
• 1 tablespoon rice vinegar or apple cider vinegar
• 1 tablespoon honey or brown sugar
• 2 cloves garlic, minced
• 1 teaspoon grated fresh ginger

Optional garnishes:

• Sliced green onions
• Sesame seeds

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Begin by slicing the steak thinly against the grain. This technique shortens the muscle fibers and ensures a tender bite. Slice the onion, bell pepper, and carrot, and separate the broccoli into small, bite-sized florets. Set the prepared ingredients aside.

Step 2: Make the Sauce

In a small bowl, whisk together soy sauce, oyster sauce, sesame oil, cornstarch, rice vinegar, honey, garlic, and ginger. This savory and slightly sweet sauce will coat the ingredients in flavorful goodness. Set the sauce aside until ready to use.

Step 3: Sear the Steak

Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Once the oil is shimmering, add the sliced steak in a single layer. Cook for 2–3 minutes on each side, allowing it to develop a golden-brown crust. Remove the steak from the pan and set it aside on a plate.

Step 4: Cook the Vegetables

In the same skillet, add the remaining tablespoon of vegetable oil. Toss in the onions and stir fry for 2 minutes until slightly softened. Add the broccoli, bell peppers, and carrots, and continue to stir fry for an additional 3–4 minutes until the vegetables are crisp-tender.

Step 5: Combine Everything

Return the cooked steak to the skillet along with any juices that have accumulated on the plate. Pour the sauce over the steak and vegetables, tossing to coat everything evenly. Cook for 1–2 minutes, stirring frequently, until the sauce thickens and clings to the ingredients.

Step 6: Serve and Garnish

Transfer the onion steak stir fry to a serving dish or individual plates. Garnish with sliced green onions and sesame seeds for an extra layer of flavor and presentation. Serve immediately with steamed rice or noodles for a complete meal.

Ingredient Background

Flank steak and sirloin are excellent choices for stir frying due to their balance of flavor and tenderness. Both cuts absorb marinades well and cook quickly when sliced thinly against the grain. The onions in this recipe act as the star vegetable, lending sweetness and depth to the dish as they caramelize slightly during cooking.

Oyster sauce adds a rich umami flavor, while soy sauce brings a salty-savory element. The addition of sesame oil, garlic, and ginger ties the sauce together with traditional Asian-inspired flavors. Fresh vegetables like broccoli, bell peppers, and carrots not only add color and crunch but also make the dish nutrient-rich.

Technique Tips

• Slice Steak Properly: Always slice steak thinly against the grain. This ensures a tender, easy-to-chew texture.
• High Heat is Key: Stir frying is all about cooking quickly at high heat. This helps maintain the crisp texture of the vegetables and prevents the meat from becoming tough.
• Don’t Overcrowd the Pan: Cook the steak in batches if necessary to allow it to sear properly rather than steaming.
• Cornstarch Slurry: The cornstarch in the sauce acts as a thickening agent. Be sure to whisk the sauce well before adding it to the skillet to avoid clumps.

Alternative Presentation Ideas

• Lettuce Wraps: Serve the stir fry in crisp lettuce leaves for a low-carb, handheld meal.
• Rice Bowls: Layer the steak and vegetables over a bed of steamed jasmine rice or brown rice.
• Noodle Stir Fry: Toss the stir fry with cooked noodles like lo mein, soba, or rice noodles for a hearty dish.
• Meal Prep Bowls: Divide the stir fry into containers with a side of quinoa or rice for grab-and-go meals throughout the week.

Additional Tips for Success

• Marinate the Steak: For added flavor, marinate the steak in a mixture of soy sauce, garlic, and sesame oil for 30 minutes before cooking.
• Keep it Crisp: Don’t overcook the vegetables—they should still have a bit of crunch when served.
• Double the Sauce: If you like extra sauce for serving over rice or noodles, consider doubling the sauce ingredients.

Recipe Variations

• Spicy Stir Fry: Add a teaspoon of chili garlic sauce or sriracha to the sauce for a spicy kick.
• Teriyaki Style: Replace the oyster sauce with teriyaki sauce and add a splash of pineapple juice for a sweeter flavor.
• Vegetarian Version: Swap the steak with tofu or tempeh, and use mushroom-based oyster sauce for a plant-based alternative.
• Mushroom Lovers: Add sliced mushrooms like shiitake or cremini to the stir fry for an earthy flavor.

Freezing and Storage

• Refrigerator: Store leftover stir fry in an airtight container for up to 3 days. Reheat in a skillet over medium heat or in the microwave.
• Freezer: Freeze portions of the stir fry in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.

Healthier Twist Ideas

• Lean Protein: Use leaner cuts of beef, such as eye of round, or substitute with chicken breast or shrimp for lower fat content.
• Reduce Sodium: Opt for low-sodium soy sauce and oyster sauce to reduce the overall sodium content.
• Add Whole Grains: Serve the stir fry with brown rice, quinoa, or farro for added fiber and nutrients.
• Extra Veggies: Bulk up the dish with additional vegetables like zucchini, snap peas, or spinach.
