Quick Beef & Broccoli Stir-Fry
This Quick Beef & Broccoli Stir-Fry is a vibrant, healthy, and incredibly fast weeknight meal, featuring tender sirloin strips and crisp vegetables coated in a savory soy-ginger sauce.
For 4 servings
In a medium bowl, toss the thinly sliced beef sirloin with 1 tablespoon of cornstarch until evenly coated. This helps tenderize the beef and create a slight crust.
In a small bowl, whisk together the soy sauce, water (or beef broth), remaining 1 tablespoon of cornstarch, brown sugar, rice vinegar, grated ginger, and minced garlic. Set aside; this is your stir-fry sauce.
Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat until shimmering. Add the beef in a single layer and stir-fry for 2-3 minutes until browned and cooked through. Do not overcrowd the pan; cook in batches if necessary. Remove the beef from the pan and set aside.
Add the remaining 1 tablespoon of vegetable oil to the same wok/skillet. Add the broccoli florets and sliced red bell pepper. Stir-fry for 3-5 minutes, until the vegetables are tender-crisp and bright green.
Return the cooked beef to the wok with the vegetables. Give the prepared stir-fry sauce a quick whisk again (as cornstarch can settle) and pour it over the beef and vegetables.
Stir constantly for 1-2 minutes, allowing the sauce to come to a simmer and thicken, coating all ingredients evenly. The sauce should be glossy and cling to the food.
Remove from heat, drizzle with toasted sesame oil, and toss gently to combine. Serve immediately over hot cooked brown rice.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Slice beef against the grain: This shortens the muscle fibers, resulting in more tender beef that's easier to chew.
- 2Don't overcrowd the pan: Cooking in batches ensures the beef browns nicely instead of steaming, which can make it tough.
- 3Prep everything ahead: Stir-frying is a very fast cooking method, so having all your ingredients chopped, measured, and ready to go (mise en place) is crucial for success.
- 4Adjust sauce consistency: If the sauce is too thick, add a tablespoon of water or broth. If it's too thin, let it simmer for another minute or two, or mix a tiny bit more cornstarch with water and stir it in.
