Prep everything first. Stir fries move fast.
Wash, trim, and slice all vegetables. Mix the soy sauce, rice vinegar, oyster sauce (if using), honey, and broth in a small bowl.
Heat your pan properly. Use a wok or large skillet over medium-high heat. When it’s hot, add the neutral oil and swirl to coat.
Start with the hardier vegetables. Add carrots and broccoli.
Stir fry 2–3 minutes until they start to soften but still have bite.
Add quick-cooking vegetables. Toss in asparagus, mushrooms, and bell pepper. Stir fry 2 minutes, keeping everything moving so it cooks evenly.
Layer in aromatics. Add the white parts of the scallions, garlic, and ginger. Stir fry 30–45 seconds until fragrant.
Don’t let the garlic brown.
Finish the veg. Add snap peas and the green parts of the scallions. Stir fry 1–2 minutes. Vegetables should be crisp-tender and bright.
Add the sauce. Pour the sauce mixture into the pan and toss to coat.
Let it bubble for 30 seconds.
Thicken lightly. Stir in the cornstarch slurry. Cook 20–30 seconds more until the sauce turns glossy and clings to the vegetables. Add sesame oil and red pepper flakes or chili oil, if using.
Taste and adjust. Add a splash more soy for salt, a squeeze of lemon for brightness, or a pinch more sweetener if needed.
Serve. Sprinkle with sesame seeds and serve hot over rice or noodles.
