Ingredients
Method
- Slice the beef thinly. Freeze the steak for 15–20 minutes to firm it up, then slice 1/4-inch strips against the grain. Pat dry and toss with a pinch of salt and pepper.
- Mix the sauce. In a bowl, whisk soy sauce, oyster sauce, rice vinegar, honey, sesame oil, red pepper flakes, and broth. Stir in the cornstarch slurry. Set aside.
- Prep the vegetables. Slice bell pepper and onion, cut broccoli into small florets, and trim snap peas. Mince garlic and ginger. Keep everything within reach.
- Heat the pan. Set a large skillet or wok over high heat. Add 1 tablespoon oil and let it shimmer. Strong heat helps you sear without steaming.
- Sear the beef in batches. Add a single layer of steak. Don’t crowd the pan. Sear 1–2 minutes per side until browned but still tender. Transfer to a plate and repeat with remaining beef, adding oil if needed.
- Stir fry the vegetables. Add a little more oil if the pan looks dry. Toss in onion, broccoli, and snap peas. Cook 2–3 minutes, stirring often. Add bell pepper, garlic, and ginger, and cook 1–2 minutes until fragrant and crisp-tender.
- Combine and sauce. Return beef and any juices to the pan. Give the sauce a quick stir and pour it in. Toss for 1–2 minutes until the sauce thickens and coats everything.
- Taste and adjust. Add a splash more soy sauce for salt, a squeeze of lime for brightness, or a dash of chili for heat. Stir in edamame or a quick scrambled egg now if using.
- Finish and serve. Top with green onions and sesame seeds. Serve immediately over rice, cauliflower rice, or noodles.
What Makes This Special
This stir fry balances lean, high-quality protein with a generous portion of vegetables, so you stay full without feeling heavy. The sauce is simple but punchy—salty, savory, a little sweet, and just enough heat to keep things interesting.
You don’t need a wok to make it work; a big skillet will do the job. And the steps are straightforward: slice, sear, toss, and eat. The best part?
You can adjust the protein, vegetables, and carbs to fit your goals or what you have on hand.

How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Portion into freezer-safe containers for up to 2 months.
Thaw overnight in the fridge for best texture.
- Reheat: Use a hot skillet with a splash of water to loosen the sauce. Heat just until warmed to avoid overcooking the beef. Microwave in short bursts if needed.
- Meal prep tip: Store rice and stir fry separately so nothing gets soggy.
Health Benefits
- High-quality protein: Lean steak provides essential amino acids that support muscle repair, satiety, and metabolism.
- Micronutrient-rich: Bell peppers, broccoli, and snap peas offer vitamin C, vitamin K, folate, potassium, and antioxidants.
- Balanced macros: Protein plus fiber from vegetables helps steady energy and fullness.
Adjust carbs and fats to your goals.
- Lower sodium control: Using low-sodium soy sauce and tasting before salting keeps sodium in check.
- Iron and B vitamins: Beef adds heme iron and B12, which support oxygen transport and energy production.
What Not to Do
- Don’t crowd the pan. Overloading causes steaming instead of searing and leads to tough beef and limp vegetables.
- Don’t skip drying the steak. Moisture prevents browning and dilutes flavor.
- Don’t overcook the beef. Thin slices only need a quick sear. Cook just to medium or medium-rare for tenderness.
- Don’t add the sauce too early. Thicken at the end so veggies stay crisp and beef doesn’t stew.
- Don’t ignore knife direction. Always slice against the grain for a tender bite.
Alternatives
- Protein swaps: Chicken breast or thigh, pork tenderloin, extra-firm tofu, or tempeh. For tofu, press well and pan-fry before saucing.
- Veggie variations: Mushrooms, baby corn, zucchini, bok choy, carrots, or cabbage.
Use what’s fresh and cut to similar sizes.
- Gluten-free: Use tamari or coconut aminos and a gluten-free oyster sauce alternative.
- Lower carb: Serve over cauliflower rice and reduce sweetener to 1 teaspoon.
- Higher heat: Add chili-garlic paste, gochujang, or fresh sliced chiles.
- Sauce tweaks: Swap honey for maple syrup, or use a teaspoon of hoisin for a sweeter, thicker glaze.
FAQ
What cut of steak is best for stir fry?
Flank, sirloin, flat iron, and skirt steak are top picks. They slice thin, cook fast, and stay tender if cut against the grain. Ribeye works too for a richer option, but you can trim excess fat to keep it leaner.
How thin should I slice the beef?

Aim for about 1/4 inch thick.
If you can almost see through it, it’s too thin and may overcook. A short freeze makes clean slicing easier.
Can I make this without a wok?
Yes. A large, heavy skillet or sauté pan works well.
Preheat until very hot and avoid crowding to keep that sear.
How do I keep the vegetables crisp?
Cut them to similar sizes, cook over high heat, and add firmer veggies first. Stop cooking as soon as they’re bright and tender-crisp. The residual heat will finish them off.
What can I use instead of cornstarch?
Arrowroot or potato starch thickens similarly.
Mix either with cold water before adding to the sauce. Avoid flour here—it can taste pasty and won’t get glossy.
How can I add even more protein?
Stir in shelled edamame, toss in a scrambled egg at the end, or serve with a side of quinoa. You can also slightly increase the steak to 1.5 lb, but sear in more batches.
Is this good for meal prep?
Yes.
Portion into containers with rice or veggies and refrigerate up to 4 days. Reheat quickly over high heat to keep texture. Add a splash of water to revive the sauce.
Can I reduce the sugar in the sauce?
Absolutely.
Use 1 teaspoon honey or omit it and add a bit more vinegar for brightness. The dish will be less glossy but still flavorful.
What oil should I use?
Choose a high-smoke-point oil like avocado, canola, peanut, or grapeseed oil. Save extra-virgin olive oil for finishing, not high heat cooking.
How do I avoid tough beef?
Slice against the grain, sear hot and fast, and don’t overcook.
If using a lean cut, consider a quick 15-minute marinade with a splash of soy sauce and a pinch of baking soda for extra tenderness.
