This beef teriyaki stir fry is quick, saucy, and packed with vegetables. Tender beef, broccoli, and peppers tossed in teriyaki sauce make an easy skillet dinner that feels like takeout but cooks at home in minutes.
To a large skillet over medium heat, add the broccoli, peppers, onions, and 1 tablespoon (15 ml) of avocado oil. Cook, stirring, for 7–10 minutes until the vegetables are crisp-tender.
4 cups (280 g) broccoli florets, 2 medium red bell peppers, 1 medium onion, 2 tbsps (30 ml) avocado oil
Transfer the vegetables to a platter. Add the steak and the remaining 1 tablespoon (15 ml) of avocado oil to the skillet. Cook for 3–5 minutes, or until the beef is just barely pink.
1-1½ lbs (450-675 g) beef (steak)
Return the vegetables to the skillet and pour in the teriyaki sauce. Stir to combine.
¾ cup (180 ml) teriyaki sauce
In a small bowl, whisk together the water and cornstarch to make a slurry. Add the slurry to the skillet and toss everything together until the vegetables are heated through and the sauce has thickened.
2 tbsps (30 ml) water, 1 tbsps (8 g) cornstarch
Sprinkle with sesame seeds and green onions before serving.
Slice the beef thin so it cooks quickly. Chilling it briefly in the freezer helps with slicing.
Any vegetables can be used, such as carrots, snap peas, zucchini, or mushrooms.
Adjust the slurry to control sauce thickness. Less keeps it lighter, more makes it stickier.
Serve over noodles, rice, or make into lettuce wraps for a lighter option.
