Slice the beef against the grain into 1/4-inch thick slices or 1/2-inch sticks. Place beef in a bowl and add soy sauce, peanut oil, cornstarch, and baking soda if using. Mix by hand to coat evenly. Allow to marinate for 10 minutes while prepping the remaining ingredients.

Pour 1/4 cup water into a large nonstick skillet over medium-high heat. Once boiling, add broccoli florets and cover. Steam for about 1 minute until bright green and just tender. Transfer broccoli to a plate and wipe pan dry if necessary.

Add peanut oil to the hot skillet and swirl to coat. Raise heat to medium-high. Distribute beef slices in a single layer and sear for 30 seconds without disturbing, until browned. Flip briefly to cook the other side. Stir and cook until lightly charred on the exterior but still pink inside.

Add minced garlic and ginger. Stir for several seconds until fragrant.
