I started by slicing the beef into thin 2-inch strips. Then, I heated my wok over medium-high heat and added the vegetable oil. You’ll know it’s ready when the oil shimmers slightly—it’s key for a perfect sear.
Once the pan was hot, I tossed in the beef strips and sprinkled with salt and pepper. They cooked for about 3–4 minutes, just until browned on the outside. Don’t overcrowd the pan—this helps the beef sear properly instead of steaming.
Next, I moved the beef to one side and added the broccoli, bell peppers, and carrots to the same pan. They cooked for around 3 minutes until slightly tender but still crisp. Then, I stirred in the minced garlic and let it sizzle for another 30 seconds.
After that, I poured in the soy sauce and brown sugar mixture, stirring everything together so the beef and vegetables were evenly coated. Once the sauce thickened slightly, I drizzled in the sesame oil and sriracha for that final burst of flavor.
Finally, I sprinkled green onions and toasted sesame seeds over the top, giving it that fresh and nutty finish. I removed the pan from heat right away to keep the veggies crisp and vibrant.
