How to Slice Beef for Maximum Tenderness
If you’ve ever ended up with chewy, tough beef in your stir-fry, it comes down to how you slice it. You must slice your flank steak against the grain. Look at the direction the muscle fibers are running, and cut perpendicular to them. For even easier slicing, place your steak in the freezer for 15 minutes before cutting—it will firm up just enough to allow for paper-thin slices!
The Perfect Sauce Thickness
The cornstarch slurry is the magic ingredient here. It turns a watery soy sauce mixture into a thick, luxurious glaze. Make sure you mix the cornstarch with cold water before adding it to the hot pan, otherwise it will instantly clump up. Once it hits the bubbling sauce, it will thicken in less than 60 seconds.
Ingredients
Method
- In a small bowl, whisk together the soy sauce, beef broth, brown sugar, sesame oil, and minced garlic.
- Heat 1 tablespoon of cooking oil in a large skillet or wok over high heat. Add the sliced flank steak and sear for 2-3 minutes until browned. Remove the beef and set aside.
- In the same skillet, add the broccoli florets and 2 tablespoons of water. Cover and steam for 3-4 minutes until tender-crisp.
- Return the beef to the skillet. Pour in the sauce mixture and bring to a simmer.
- Stir in the cornstarch slurry and cook for 1-2 minutes until the sauce has beautifully thickened and coated the beef and broccoli. Serve hot over rice.
