Start by washing and chopping the broccoli into small, bite-sized florets, and slicing the mushrooms evenly. Mince the garlic and ginger finely, ready to be added at the right moment.
Place your seasoned wok or skillet over medium-high heat until it shimmers and emits a gentle sizzling sound. Pour in 1-2 tablespoons of oil, coating the surface evenly.
Add the sliced mushrooms to the hot pan. Cook for 2-3 minutes, stirring occasionally, until they turn golden brown and release a fragrant, earthy aroma. They should be slightly crispy around the edges.
Push the mushrooms to one side of the pan, then add the broccoli to the empty space. Stir frequently, cooking for about 3-4 minutes until the broccoli turns a vibrant green and just begins to crisp around the edges.
Create space in the center of the pan and add the minced garlic and ginger. Cook for 30 seconds, stirring constantly until fragrant—this fills the kitchen with a spicy, aromatic scent.
Pour in the soy sauce and drizzle the sesame oil over the vegetables. Sprinkle in red pepper flakes. Toss everything together quickly, ensuring the sauce coats all ingredients evenly and the vegetables are glossy and fragrant.
Cook for another minute, allowing flavors to meld and vegetables to develop a slight caramelization. The broccoli should be crisp-tender, and the mushrooms deeply fragrant.
Turn off the heat and let the stir fry rest for 30 seconds to settle flavors. Finish by drizzling the sesame oil for a nutty aroma, giving everything a final toss.
Serve immediately in warm bowls, garnished with optional sesame seeds or chopped scallions. Enjoy the hot, smoky aroma and crisp-tender textures with each bite.
