Ingredients:
- lbs Flank Steak or Sirloin, sliced thinly against the grain
- Tbsp Soy Sauce (Low Sodium)
- tsp Sesame Oil
- tsp Cornstarch
- /2 tsp freshly ground Black Pepper
- Tbsp Soy Sauce (or Tamari)
- Tbsp Oyster Sauce (or Vegetarian Mushroom Sauce)
- Tbsp Rice Vinegar
- Tbsp Brown Sugar, packed
- tsp Chili Garlic Sauce (Sriracha or Sambal Oelek)
- tsp finely grated Fresh Ginger
- clove Garlic, minced
- /2 cup Beef Broth or Water
- tsp Cornstarch (for thickening)
- Tbsp High Smoke Point Oil (Canola, Peanut, or Grapeseed Oil), divided
- large Yellow Onion, sliced thickly
- large Bell Peppers (one red, one yellow), sliced into strips
- cup Broccoli florets
- Scallions (Green Onions), sliced, white and green parts separated
- Toasted Sesame Seeds, for garnish
Instructions:
- Marinate the Beef: In a bowl, toss the sliced steak with marinade ingredients (Soy Sauce, Sesame Oil, Cornstarch, Pepper). Set aside for at least 15 minutes.
- Prepare the Sauce: In a small bowl, whisk together all Stir-Fry Sauce ingredients until the sugar is dissolved and the cornstarch is fully incorporated. Set aside.
- Sear the Beef (In Batches!): Heat half the oil in the wok over high heat until shimmering. Add half the steak in a single layer. Cook quickly (1-2 minutes per side) until nicely browned. Remove immediately and set aside. Repeat with remaining oil and steak.
- Sauté Aromatics & Vegetables: Add the white parts of the scallions and the ginger/garlic to the hot wok. Cook for 30 seconds until fragrant. Add the onions and peppers (and broccoli, if using). Stir-fry vigorously for 2–3 minutes until vegetables are crisp-tender.
- Combine and Thicken: Return the seared steak (and any accumulated juices) to the wok. Give the prepared sauce one final quick whisk and pour it over the beef and vegetables.
- Finish: Toss everything continuously for 60–90 seconds until the sauce bubbles vigorously and thickens to coat everything beautifully.
- Serve: Remove from heat. Stir in the green parts of the scallions. Serve immediately over rice, garnished with sesame seeds.
