Beef and Broccoli with a Glossy Garlic-Ginger Sauce
Not rated yet. Be the first.
Slice the flank steak thin, toss it in baking soda and cornstarch, and in thirty-five minutes the table goes quiet except for forks. Bright broccoli, glossy garlic-ginger sauce, and rice to catch every drop.
The short version
Slice flank steak thin against the grain and toss it with baking soda and cornstarch for 15 minutes. Sear the beef in a hot skillet, stir-fry the broccoli, then bring both together in a quick soy-garlic-ginger sauce. Serve over rice. 35 minutes.
What makes ours better
the tricks Nonna pretends she never taught me
-
Velvet the beef with baking soda and cornstarch. Baking soda raises the surface pH so the proteins don't squeeze tight, and cornstarch gives a silky coating. Cheap flank steak comes out tender.
-
Freeze the steak for 20 minutes before slicing. Firm meat slices thin and even against the grain, which is half of what makes stir-fried beef tender.
-
Sear the beef in a single layer without stirring. Meat that sits on hot metal browns. Meat that is stirred constantly steams and turns gray.
-
Mix the sauce before you start. A stir-fry takes minutes. If the sauce is measured and waiting, nothing overcooks while you search for the soy sauce.

Steps
deep breath. you’ve got this.
-
Marinate the beef
In a bowl, toss the sliced beef with the baking soda, cornstarch, 1 tablespoon soy sauce and 1 teaspoon sesame oil until every slice is coated. Let it sit for 15 minutes. Rinse off the baking soda in a colander under cold water, then drain and pat dry with paper towels.
Don't marinate longer than 30 minutes, or the beef turns mushy.
About 15 min. Cook mode has a timer for this step.
-
Mix the sauce
Whisk the broth, soy sauce, oyster sauce, brown sugar, cornstarch and 1 tablespoon sesame oil in a bowl until the cornstarch dissolves. Stir the garlic, ginger and pepper flakes together in a small dish.
-
Blanch the broccoli
Boil a pot of water and drop in the florets for 45 seconds. Drain and rinse under cold water, then shake off the water well. The broccoli should be bright green and barely tender.
Dry broccoli sears. Wet broccoli steams and spits.
-
Sear the beef
Heat 2 tablespoons oil in a large skillet over high heat until it shimmers. Add the beef in one layer, working in two batches if needed. Cook 1 minute without moving it, flip, and cook another minute until browned. Move to a plate.
About 3 min. Cook mode has a timer for this step.
-
Cook the broccoli and aromatics
Add the last tablespoon of oil, then the broccoli, and stir-fry 2 minutes until it picks up some browned spots. Push it aside, add the garlic and ginger, and cook 20 seconds until fragrant.
-
Bring it together
Stir the sauce once and pour it in. Simmer 1 to 2 minutes until it thickens and coats a spoon. Return the beef and any juices to the pan and toss for 30 seconds. Serve right away over rice.
Good to know
read this before somebody asks for seconds
- Slice against the grain. Flank has long visible lines of muscle fiber, and you want your knife crossing them.
- Sirloin, skirt or ribeye work too. For deeper flavor, use half flank and half ribeye.
- For a vegetable boost, add sliced red pepper or mushrooms with the broccoli.
- Swap the oyster sauce for 1 tablespoon extra soy sauce and 1 teaspoon sugar if you don't have any.
- Storage. Fridge, 3 days in an airtight container. Reheat in a skillet with a splash of water for 2 to 3 minutes. Broccoli softens, so we don't freeze this one.
Questions, answered
the questions my cousins text me
Why is my stir-fried beef tough?
Usually it's sliced with the grain, sliced too thick or cooked too long. Slice thin against the grain, use the baking soda step and sear for no more than 2 minutes total.
What cut of beef is best for beef and broccoli?
Flank steak is the standard, with sirloin and skirt steak close behind. All need to be sliced thin against the grain.
Is the baking soda step necessary?
No, but it is the reason takeout beef is so tender. Skip it and the beef will taste fine, just chewier.
How do I keep the broccoli bright green and crisp?
Blanch it 45 seconds, cool it under cold water and dry it well before stir-frying. It finishes in the pan in a couple of minutes.
Can I use frozen broccoli?
Yes. Skip the blanching, thaw and pat the florets dry, and stir-fry about 3 minutes. It will be softer than fresh.
