• ¼ tsp baking soda – Tenderizes the beef (restaurant technique).

For the Stir-Fry Sauce

• ¼ cup oyster sauce – Adds umami richness.
• ¼ cup low sodium soy sauce – Provides salty, savory depth.

Step-by-Step Instructions

Slice and Marinate the Beef
Slice beef thinly against the grain. In a bowl, combine soy sauce, cornstarch, black pepper, and baking soda. Mix thoroughly and let marinate for 10–15 minutes.

Prepare the Sauce
Whisk together oyster sauce, soy sauce, water, cornstarch, brown sugar, and black pepper in a bowl. Set aside.

Sear the Beef
Heat 1–2 tablespoons oil in a large pan over medium-high heat. Spread beef in a single layer and cook 1–2 minutes per side until browned. Remove and set aside.

Blanch the Broccoli
Boil broccoli for exactly 2 minutes, then drain. It should remain slightly firm as it will finish cooking in the sauce.

Sauté the Garlic
Add a small amount of oil to the same pan. Reduce heat to medium and sauté garlic until lightly golden and fragrant.

Thicken the Sauce
Pour prepared sauce into the pan. Stir continuously until it begins to thicken and become glossy.

Combine and Finish
Return beef and broccoli to the pan. Toss thoroughly to coat in sauce. Cook 1–2 minutes until heated through.

Serve immediately over steamed white rice or noodles.

Recipe Notes & Tips

• Slice Against the Grain – Ensures tender beef texture.
• Don’t Overcrowd the Pan – Cook beef in batches if necessary.
• Blanch Broccoli Briefly – Prevents mushy texture.
• Use High Heat for Searing – Locks in flavor and creates caramelization.
• Adjust Sodium if Needed – Use reduced-sodium sauces or dilute with extra water.
• Let Sauce Fully Thicken – Cornstarch needs heat to activate properly.

Storage & Serving Tips

• Store leftovers in an airtight container up to 3 days in the refrigerator.
• Reheat gently in a skillet to maintain texture.
• Add a splash of water when reheating to loosen sauce.
• Avoid freezing as broccoli texture may become soft.

Creative Variations to Try

• Spicy Version – Add red pepper flakes or chili paste.
• Low-Carb Option – Serve over cauliflower rice.
• Veggie Boost – Add snap peas, bell peppers, or carrots.
• Chicken Swap – Substitute thin-sliced chicken breast.

Troubleshooting Common Issues

• Beef Is Tough – Slice thinner and ensure baking soda is included in marinade.
• Sauce Too Thin – Simmer longer or add a small cornstarch slurry.
• Broccoli Too Soft – Reduce blanching time to 1 minute.
• Too Salty – Add extra water and a pinch of sugar to rebalance.

Why This Recipe Works

The baking soda in the marinade raises the pH of the meat’s surface, preventing protein bonds from tightening too quickly and creating tender, restaurant-style beef. Cornstarch locks in moisture and thickens the sauce into a glossy coating. The balance of oyster sauce, soy sauce, and brown sugar creates layered umami depth, while blanching broccoli separately ensures bright color and crisp-tender texture. At just over 300 calories per serving, it’s a protein-rich, satisfying meal without excessive heaviness.

This beef and broccoli stir fry is proof that you don’t need take-out for bold, satisfying flavor. With simple ingredients and smart technique, you can create a healthier, fresher version at home in under 30 minutes. Adjust seasoning to your taste, pair it with your favorite side, and enjoy a dependable dinner that’s both comforting and nutritious.
