Let’s get you started on making this delightful dish. Follow these steps, and you’ll be savoring the flavors in no time.

First up, let’s get that flank steak ready. Slice it against the grain into thin strips. This is crucial for tenderness. Now, in a bowl, combine the beef strips with 2 teaspoons of baking soda, a pinch of salt, and a tablespoon of water (just enough to coat).

Let it sit for about 30 minutes. I promise it’s worth the wait. The baking soda does wonders for the texture.

While the beef is soaking, let’s whip up the sauce. In a small bowl, mix together the oyster sauce, soy sauces, chicken broth, toasted sesame oil, fish sauce, and black vinegar. Stir in the brown sugar and cornstarch until fully blended. You'll want to keep this close at hand, as it will come together quickly once we start cooking.

Heat a large skillet or wok over medium-high heat. Add a tablespoon of your chosen oil (I prefer avocado oil for its high smoke point).

Once the oil is shimmering, add the marinated beef strips in a single layer. Let them cook undisturbed for about two minutes until brown, then stir-fry them for another minute to ensure they are fully cooked.

With the beef cooked, it’s time for the star ingredients. Add the minced garlic to the pan and stir-fry for about 30 seconds.

The garlic will start to infuse the oil with fragrant goodness. Then, toss in the broccoli florets and stir everything well. I love the colors!

Now, pour the prepared sauce over the beef and broccoli mixture. Stir well to coat everything evenly. Bring it to a simmer, and watch the sauce thicken. This usually takes about two to three minutes. The aroma wafting through your kitchen will have everyone asking what’s for dinner!

Once everything is coated beautifully, remove from heat and garnish with sliced green onions. Serve the dish over rice. Trust me, you’ll want to scoop every last bit of that sauce.
