Sizzling Beef and Onion Stir-Fry Step-by-step instructions

Before you start

Before turning on the heat, ensure all ingredients are fully prepped, measured, and organized within arm's reach of your stove. Stir-frying happens incredibly fast, leaving absolutely no time for chopping or measuring once the cooking begins.

Slice the beef, cut the vegetables, and have your savory sauce measured out in a small bowl so everything is ready to go into the hot wok immediately.

Instructions

Prep and Assembly

1. 1Prep the Beef and Vegetables
   Slice the beef into thin strips. Slice the onion and red pepper into uniform strips. Keep the sliced beef in the refrigerator until ready to cook.
   Look for The beef and vegetables should be sliced to a uniform thickness.
   Tip Placing the beef in the freezer for fifteen minutes makes slicing thin strips much easier.

The beef is thinly sliced and resting safely in the refrigerator to keep cool. The onions and red peppers are cut into uniform strips, ensuring they cook evenly. The savory sauce is measured and ready in a bowl near the cooking station, showing no preparation delays.

High-Heat Beef Searing

2. 2Sear the Beef
   Heat a wok over high heat until smoking. Add the beef strips in a single layer and sear without moving for one minute, then toss and cook for another minute until the beef reaches an internal temperature of 145°F (63°C). Remove the beef from the wok and let it rest for 3 minutes.
   Look for The beef should have a deep brown sear on the edges.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Do not overcrowd the wok; sear the beef in batches if necessary.

The beef strips are seared quickly in the smoking-hot wok, developing a rich brown crust on the edges.

The meat is removed from the pan at an internal temperature of 145 degrees Fahrenheit, which is 63 degrees Celsius, and is left to rest for three minutes, releasing savory aromas and retaining its natural juices.

Vegetable Stir-Fry and Glazing

3. 3Stir-Fry the Vegetables
   Add the sliced onions and red peppers to the hot wok. Stir-fry constantly over high heat for two to three minutes until the onions are slightly translucent but still crisp.
   Look for The vegetables should be vibrant in color and tender-crisp.
   Tip Keep the vegetables moving constantly to prevent burning in the hot wok.
4. 4Glaze and Serve
   Return the seared beef and any accumulated juices to the wok. Pour the savory sauce over the ingredients. Toss vigorously for one minute until the sauce bubbles, thickens, and glazes the beef and vegetables. Transfer to a hot cast iron platter and serve immediately.
   Look for The sauce should bubble vigorously and coat the beef and vegetables in a glossy glaze.
   Tip Heat the cast iron platter in the oven beforehand to get that signature restaurant sizzle.

The onions and red peppers are tossed vigorously, becoming slightly translucent yet remaining delightfully crisp. The savory sauce is poured in, bubbling instantly and thickening into a glossy, dark glaze that clings perfectly to the tender beef and vegetables, filling the kitchen with a rich, savory fragrance.

Common mistakes

The most common mistake is crowding the pan, which lowers the cooking temperature and causes the beef to steam in its own juices instead of searing.

This results in tough, gray meat rather than caramelized, tender strips. Cook the beef in batches if using a smaller pan, ensuring the surface remains intensely hot throughout the process to get that perfect sear.

How to tell it’s done

The beef is perfectly cooked when it reaches a safe internal temperature of 145 degrees Fahrenheit, which is 63 degrees Celsius, followed by a mandatory three-minute rest.

The vegetables should be tender-crisp, holding their shape and vibrant colors, while the savory sauce should be thick enough to coat the back of a spoon beautifully, creating a glossy glaze over the beef and onions.
