A great stir fry is all about high heat and fast cooking. The beef gets a quick sear while the peppers stay crisp-tender, and a simple sauce ties everything together in minutes.
This is the weeknight dinner you will come back to again and again. Prep everything before you start cooking, because once the wok is hot, things move fast.

Why a wok helps here
High-heat cooking gets easier when the pan can move food quickly without steaming it. That is the real advantage for stir-fries like this one.
This recipe benefits most from faster heat response and more tossing room.
- Keeps vegetables and proteins from steaming
- Makes quick sauce reduction easier
A flat-bottom wok is the most useful upgrade if you cook stir-fries more than once in a while.

Why the sesame oil matters
A small amount of toasted sesame oil changes the aroma fast. It is one of the easiest ways to make a sauce or dressing taste more complete.
This ingredient adds most of its value in aroma and finish.
- Adds nutty depth with very little effort
- Useful in noodles, dressings, and marinades
Toasted sesame oil is a small bottle that tends to have outsized payoff.

- Can I use other vegetables?
- Snow peas, broccoli, zucchini, and snap peas all work well. Cut everything to a similar size.
- Can I use a regular skillet?
- Yes, just make sure it is very hot. A cast iron skillet holds heat well for stir frying.
