  • 1 Tbsp Fresh Ginger grated
  • 1/2 cup Beef Broth low sodium
  • 1/4 cup Soy Sauce low sodium
  • 2 Tbsp Oyster Sauce or vegetarian alternative
  • 1 Tbsp Brown Sugar
  • 1 tsp Sesame Oil
  • 2 Tbsp Cornstarch for slurry
  • 3 Tbsp Cold Water for slurry
  • 2 Tbsp High smoke point oil Avocado, Peanut, or Canola
  • 1 tsp Toasted Sesame Seeds for garnish

Equipment

  • Wok or large high-sided skillet
  • Cutting board
  • Chef's knife
  • Measuring cups and spoons
  • Two medium mixing bowls
  • Whisk
  • Spatula or stirring utensil

Method
 

  1. Prep and Velvet the Beef: Slice the beef thinly against the grain (about 1/4 inch thick). In a medium bowl, toss the sliced beef with the baking soda, cornstarch, and a pinch of salt and pepper. Let this mixture rest for at least 15 minutes, but no more than 30 minutes, while preparing other ingredients.
  2. Prepare the Sauce and Aromatics: While the beef rests, whisk together all the sauce ingredients: beef broth, soy sauce, oyster sauce, brown sugar, and sesame oil. In a separate small bowl, mix the 2 Tbsp cornstarch with 3 Tbsp cold water to create the slurry. Mince the garlic and grate the ginger.
  3. Cook the Vegetables in Batches: Heat 1 tablespoon of high smoke point oil in your wok or largest skillet over high heat until it just begins to smoke. Add the broccoli and carrots first. Stir fry them for 3 to 4 minutes until they are crisp-tender. Add the bell peppers for the last minute. Remove all the vegetables immediately and set them aside in a separate bowl.
  4. Sear the Velveting Beef: Add the remaining oil to the hot wok. Once shimmering, add the velveted beef in a single layer, ensuring not to overcrowd the pan. Sear the beef for 60 to 90 seconds per side until beautifully browned and caramelized. Remove the beef and add it to the bowl with the cooked vegetables. Repeat if cooking in batches.
  5. Build the Sauce: Reduce the heat slightly to medium-high. Add the minced garlic and grated ginger to the wok and cook for about 30 seconds until fragrant (do not let them burn). Pour in the prepared sauce mixture and bring it to a gentle simmer. Whisk the cornstarch slurry one last time and slowly pour it into the simmering sauce while stirring continuously until the sauce thickens rapidly and becomes glossy.
  6. Finish the Stir Fry: Once the sauce is thick, immediately return the beef and the vegetables to the wok. Toss everything gently but quickly to coat all the ingredients evenly in the rich sauce. Cook for just 30 seconds to 1 minute to warm through. Serve immediately over hot rice, garnished with fresh scallions and toasted sesame seeds.

Notes

Always use high heat and avoid overcrowding the wok; this prevents steaming and ensures a proper sear and crisp texture. For an authentic flavor boost, add a splash of dry sherry or Shaoxing rice wine to the sauce mixture before thickening. If substituting oyster sauce, use a high-quality mushroom sauce or a blend of extra soy sauce and a dash of molasses for depth. Slicing the beef against the grain is mandatory for maximum tenderness.
