The Protein

• 1 ½ lb flank steak: Thinly sliced against the grain (this is CRUCIAL for tender beef – I’ll show you how in the tips section)

The Veggies

• 3 cups broccoli florets: Cut into bite-sized pieces (pro tip: save the stems for stir-fries or slaws!)
• 1 red bell pepper: Sliced into thin strips (adds gorgeous color)
• 1 orange bell pepper: Also sliced (because why not make it pretty?)

The Aromatics

• 3 cloves garlic: Minced (fresh only – none of that jarred stuff!)
• 1 tablespoon fresh ginger: Minced (peel it with a spoon – game changer)

The Sauce (aka Liquid Gold)

• ¼ cup low-sodium soy sauce: The base of our flavor bomb
• ¼ cup beef broth: Adds depth without watering things down
• 2 tablespoons brown sugar: Just enough sweetness to balance the salt
• 1 tablespoon cornstarch: Our thickening agent (no clumps please!)

The Finishers

• 2 tablespoons vegetable oil: For high-heat cooking (divided use)
• 1 teaspoon sesame oil: Added at the end for that authentic aroma
• 1 tablespoon sesame seeds: Because everything’s better with a little crunch

See? Nothing crazy or hard-to-find here. Just fresh, simple ingredients that come together to make something way better than anything that comes in a cardboard box. Now let’s get cooking!

How to Make Beef and Broccoli Stir Fry

Alright, let’s get cooking! The key to perfect stir fry is having everything prepped and ready to go before you turn on the heat. Trust me, once that skillet gets hot, things move FAST. Here’s exactly how to nail this beef and broccoli stir fry every single time.

Preparing the Sauce

First things first – let’s make that magical sauce. Grab a small bowl and whisk together the soy sauce, beef broth, brown sugar, and cornstarch until it’s completely smooth. No lumps allowed! I like to use a fork for this – it helps break up any cornstarch clumps instantly. The mixture should look like thin caramel when it’s ready. Set this aside near your stove – you’ll thank me later when everything’s sizzling and you don’t have to scramble to find it.

Cooking the Beef

Now, heat 1 tablespoon of vegetable oil in your largest skillet over medium-high heat. You’ll know it’s hot enough when a drop of water sizzles immediately. Add your sliced beef in a single layer – don’t crowd the pan! Let it sear undisturbed for about 1 minute to get that beautiful brown crust, then give it a good stir. Cook for another 2-3 minutes until the beef is just cooked through but still tender. Pro tip: The beef will continue cooking when we add it back later, so don’t overdo it now! Transfer the beef to a clean plate and cover loosely with foil.

Stir-Frying Vegetables

Same pan, add the remaining tablespoon of oil. Toss in your broccoli and bell peppers – you should hear that satisfying sizzle! Stir-fry for about 3 minutes until the veggies are bright green and crisp-tender. Now add the garlic and ginger – this is when your kitchen will smell AMAZING. Cook for just 30 seconds, stirring constantly. Any longer and the garlic might burn, and nobody wants that bitter taste.

Combining Everything

Time for the grand finale! Return the beef to the skillet and pour in that sauce we made earlier. Stir everything together well and let it simmer for about 2 minutes. You’ll see the sauce start to thicken and cling to every piece of beef and veggie. When it coats the back of a spoon nicely, you’re done! Finish with a drizzle of sesame oil and sprinkle of sesame seeds for that authentic touch. Serve immediately – this dish waits for no one!

Tips for the Best Beef and Broccoli Stir Fry

Listen, I’ve burned my fair share of stir fries before getting this recipe just right. Here are my hard-earned secrets for beef and broccoli perfection every single time:

Slice that beef like you mean it

Cutting flank steak against the grain makes all the difference – it’s the difference between tender bites and chewing leather. Look for those long muscle fibers and slice perpendicular to them. And keep those slices thin – about 1/4 inch thick. Pro tip: Pop the meat in the freezer for 15 minutes first – it makes slicing way easier!

Sauce too thin? Too thick? Fix it!

If your sauce isn’t thickening enough, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir it in. Too thick? Splash in a bit more beef broth. Remember, sauces continue thickening as they cool, so err on the slightly thin side.

Don’t drown your veggies

That crisp-tender texture is everything! Cook your broccoli and peppers just until they turn bright green – about 3 minutes max. They’ll keep cooking from residual heat after you take them off the burner. Mushy veggies = sad stir fry.

The garlic-ginger golden rule

Add these aromatic powerhouses last and cook them for just 30 seconds. Any longer and they’ll burn, turning bitter. You want them fragrant but not browned – that’s when they’ll give you maximum flavor without overpowering the dish.

High heat is your friend

Don’t be shy with that burner! Medium-high heat gives you that perfect sear on the beef and keeps your veggies crisp. If your pan isn’t hot enough, everything will steam instead of stir-fry. Listen for that satisfying sizzle when ingredients hit the pan.

Serving Suggestions for Beef and Broccoli Stir Fry

Now for the best part – loading up your plate! This beef and broccoli stir fry is crazy versatile. Here’s how I love to serve it:

Rice is nice

You can’t go wrong with steaming hot jasmine rice – it soaks up that amazing sauce like a dream. Brown rice works great too if you want something heartier. My little trick? I like to sprinkle some chopped green onions over the rice first for extra color and freshness.

Noodle lovers unite

Sometimes I swap the rice for noodles – toss everything with cooked lo mein or udon noodles right in the skillet. The thick noodles grab onto the sauce beautifully. If I’m feeling fancy, I’ll add some shredded carrots and bean sprouts for extra crunch.

Don’t skip the garnishes

That final sprinkle of sesame seeds isn’t just for looks – they add the perfect nutty crunch. Sometimes I’ll throw on some extra chopped cilantro or a squeeze of lime if I want brightness. And if you like heat, a drizzle of sriracha or sprinkle of crushed red pepper flakes takes it next level.

Make it a meal

For a complete dinner, I’ll often add some quick sides – maybe some store-bought potstickers or egg rolls warmed in the toaster oven. A simple cucumber salad with rice vinegar makes a refreshing contrast to the rich stir fry. And don’t forget the fortune cookies for dessert – because why not?

Storing and Reheating Beef and Broccoli Stir Fry

Okay, confession time – I almost never have leftovers of this beef and broccoli stir fry because it’s just that good. But when I do manage to save some (usually by hiding it behind the milk carton), here’s how I keep it tasting fresh and delicious for round two:

Storing it right

First rule – get that stir fry into an airtight container fast. I’m talking within an hour of cooking, especially in summer. Glass containers are my go-to because they don’t absorb smells (we’ve all had that plastic container that permanently smells like garlic, right?). Press plastic wrap directly on the surface before sealing to keep air out. It’ll stay good in the fridge for 3-4 days.

Freezer magic

Yes, you can freeze stir fry! I portion it into individual servings in freezer bags (squeeze out all the air) or small containers. The texture changes a tiny bit, but it’s still crazy good. Just thaw overnight in the fridge when you’re ready. Frozen beef and broccoli keeps its flavor for about 2-3 months.

Reheating like a pro

Microwaving is fine in a pinch, but for best results, I grab my trusty skillet. Medium heat with a splash of water or beef broth brings everything back to life without drying out. Stir constantly – it only takes 3-4 minutes. If using the microwave, cover with a damp paper towel and go 60 seconds at a time, stirring between bursts. That keeps the beef tender instead of rubbery.

Reviving the sauce

Sometimes the sauce thickens too much in the fridge. No worries! Just add a tablespoon of water or broth when reheating and stir well. If it’s separated, a quick whisk brings it back together. And that sesame oil flavor fades, so I always add another tiny drizzle before serving leftovers.

P.S. – The broccoli will lose some crispness after storing, but that’s totally normal. Still tastes amazing over fresh rice though!

Beef and Broccoli Stir Fry Variations

Okay, here’s the fun part – making this beef and broccoli stir fry your own! I love playing with different versions depending on what’s in my fridge or who’s coming for dinner. Here are my favorite twists that still keep the spirit of the original:

Protein swaps

Not feeling beef tonight? No problem! Chicken thighs work beautifully here – just slice them thin and cook a minute longer. For my vegetarian friends, extra-firm tofu (pressed and cubed) or tempeh makes an awesome substitute. And shrimp? Oh yes – just add them at the very end since they cook so fast.

Veggie adventures

Broccoli’s great, but sometimes I mix it up with whatever’s seasonal. Snow peas and mushrooms give a whole new texture. Thinly sliced carrots add sweetness (pro tip: shave them with a peeler for quick cooking). And when I’m feeling fancy, baby corn and water chestnuts bring that authentic takeout crunch.

Heat lovers unite

If you like it spicy like I do, try adding sliced fresh chili peppers with the garlic and ginger. Or stir in a spoonful of chili garlic sauce or sambal oelek when you make the sauce. My husband always drizzles sriracha on his portion – I swear he’d put it on cereal if I let him!

Flavor boosters

For extra umami, I sometimes swap half the soy sauce for oyster sauce or fish sauce (just a little – it’s potent!). A splash of rice wine vinegar at the end brightens everything up. And when I’m feeling extra, I garnish with chopped peanuts instead of sesame seeds for serious crunch.

Diet-friendly tweaks

Gluten-free? Use tamari instead of soy sauce. Watching sugar? Swap the brown sugar for a teaspoon of honey. Low-carb? Serve over cauliflower rice or just enjoy it as-is – it’s plenty flavorful without any grains.

The beauty of stir fry is how adaptable it is – don’t be afraid to experiment! Just keep that high heat and quick cooking time, and you really can’t go wrong.

Nutritional Information

Now, I’m no nutritionist, but I do like having a general idea of what’s going into my meals! Keep in mind these numbers are just estimates—actual values can vary based on the exact ingredients and brands you use (and let’s be real, who actually measures that last drizzle of sesame oil perfectly?).

This beef and broccoli stir fry packs a good protein punch from the flank steak and balances it with plenty of veggie goodness. The homemade sauce keeps things reasonable on the sugar front compared to takeout versions. And that glorious sesame oil? Yeah, it adds some healthy fats that make the flavors pop.

If you’re watching specific macros or have dietary needs, I’d recommend plugging your exact ingredients into one of those handy nutrition calculators. But overall, this is one of those meals that feels indulgent while still being pretty darn wholesome. Now if you’ll excuse me, I’ve got some perfectly balanced beef and broccoli to go devour!

Frequently Asked Questions

Can I use frozen broccoli instead of fresh?

Absolutely! I do this all the time when I’m in a pinch. Just thaw the broccoli first and pat it dry with paper towels—otherwise you’ll end up with a watery stir fry. Frozen florets might get a bit softer than fresh, but the flavor still works great. Pro tip: Add them straight from frozen during the last minute of cooking if you like them crisp.

How can I make this beef and broccoli stir fry spicier?

Oh, I love this question! My favorite way is to add sliced red chili peppers when cooking the garlic and ginger—they infuse the whole dish with heat. If you want more control, serve with sriracha or chili oil on the side. You could also stir in a teaspoon of red pepper flakes when making the sauce. Warning: It might become addictively spicy!

What’s the best cut of beef besides flank steak?

If you can’t find flank steak, skirt steak works beautifully—just slice it extra thin. Sirloin or ribeye are great too if you don’t mind spending a bit more. The key is cutting against the grain no matter what cut you use. I once tried it with chuck roast (on sale!) and it worked surprisingly well after a quick marinade.

Can I make this recipe ahead of time?

You can prep everything in advance—slice the beef, chop the veggies, and mix the sauce separately. But honestly? This dish shines when cooked fresh. If you must make ahead, undercook the veggies slightly and store components separately. The sauce might thicken too much in the fridge—just thin it with a splash of broth when reheating.

Is there a substitute for cornstarch in the sauce?

For sure! Arrowroot powder works exactly the same way—use the same amount. If you’re in a real bind, mix 2 teaspoons of flour with 1 tablespoon cold water as a thickener. Just know it won’t get quite as glossy. I’ve even used potato starch in a pinch—the sauce was a touch cloudier but still delicious.

Alright, enough talk – it’s time to grab that skillet and make some magic happen! This beef and broccoli stir fry is seriously one of those recipes that’ll make you feel like a weeknight kitchen hero.
