Ingredients You’ll Need

• 1 pound flank steak or sirloin, thinly sliced against the grain (this ensures it stays tender)
• 3 tablespoons cornstarch (for that light, crispy coating on the beef)
• 1/4 cup low-sodium soy sauce or tamari (the base of our savory sauce)
• 3 tablespoons honey (for that perfect sticky sweetness)
• 2 tablespoons rice vinegar (adds a bright, tangy note)
• 1 tablespoon toasted sesame oil (brings that classic, nutty aroma)
• 3 cloves garlic, minced (for a punch of flavor)
• 1 tablespoon fresh ginger, grated (adds a warm, zesty kick)
• 1 large head of broccoli, cut into florets (our fresh, green veggie star)
• 2 tablespoons neutral oil, like avocado or vegetable oil (for high-heat cooking)
• 2 teaspoons sesame seeds, for garnish (a pretty, crunchy finish)
• 2 green onions, sliced, for garnish (adds a fresh pop of color and flavor)

Let’s Get Cooking Step by Step

1. Start by prepping your beef. Slice it thinly against the grain—this is the secret to tender bites! Place the slices in a medium bowl and toss them with the cornstarch until every piece is lightly coated. This little step makes all the difference for a crispy exterior.
2. Now, let’s make that irresistible sauce. In a small bowl or measuring cup, whisk together the soy sauce, honey, rice vinegar, sesame oil, minced garlic, and grated ginger. Set this saucy goodness aside.
3. Heat one tablespoon of your neutral oil in a large skillet or wok over medium-high heat. Once the oil is shimmering, add the broccoli florets. Stir-fry them for about 3-4 minutes until they’re bright green and just starting to get some crispy edges. Add a couple tablespoons of water to the pan, cover it with a lid, and let the broccoli steam for another 2 minutes until it’s tender-crisp. Scoop the broccoli out and onto a clean plate.
4. Add the remaining tablespoon of oil to the hot skillet. Give your cornstarch-dusted beef another toss in the bowl, then add it to the skillet in a single layer. Let it sear for about 1 minute without moving it to get a good crust, then stir and cook for another 2-3 minutes until it’s no longer pink.
5. Pour your prepared sauce right over the beef. It will bubble up and thicken almost immediately—this is the magic happening! Let it cook for another minute, stirring to coat every piece.
6. Add the cooked broccoli back into the skillet and toss everything together until it’s all glazed in that sticky sesame sauce. Give it a taste—this is your moment. Does it need a pinch more salt? A tiny drizzle more honey? Make it yours.
7. Take the skillet off the heat and serve immediately. Garnish with a generous sprinkle of sesame seeds and those sliced green onions.

Shortcut Tips For Busy Weeknights

• Pre-cut is your friend! Many grocery stores sell pre-sliced stir-fry beef and pre-cut broccoli florets. This can shave precious minutes off your prep time.
• Make the sauce ahead. You can whisk the sauce ingredients together up to 3 days in advance and keep it in a jar in the fridge. Just give it a good shake when you’re ready to cook.
• Use a bagged coleslaw mix. Honestly, if you’re really pressed for time, a bag of broccoli slaw or even classic coleslaw mix (just cabbage and carrots) makes a fantastic, quick-cooking addition or substitute.
• Double the batch. This recipe reheats beautifully, so make a double portion of the sauce and beef and you’ve got an easy lunch ready to go for the next day.
• Keep your skillet HOT. A properly hot pan is the key to a successful stir-fry. It sears the meat instead of stewing it, giving you the best texture.

Variations & Substitutions

This recipe is wonderfully flexible. Don’t eat beef? Swap in an equal amount of thinly sliced chicken breast or thighs. For a vegetarian version, extra-firm tofu or even chickpeas work great (just pat the tofu dry and toss it in cornstarch as you would the beef). Not a fan of broccoli? Try sliced bell peppers, snap peas, or shredded carrots instead. If you need a gluten-free option, simply ensure you’re using tamari instead of soy sauce. And if you like a little heat, a teaspoon of sriracha or a pinch of red pepper flakes whisked into the sauce is absolutely delicious.

Serving Ideas & Pairings

This stir fry is a complete meal all on its own, but it’s also fantastic served over a bed of fluffy white rice, brown rice, or cauliflower rice for a lighter option. For a more substantial dinner, quinoa or soba noodles are excellent choices. A simple side of quick-pickled cucumbers or a light green salad with a ginger-sesame dressing would round out the meal perfectly. It’s one of those dinner dishes that feels both special and completely effortless.

Storage & Reheating Instructions

Let any leftovers cool completely before storing them. They’ll keep in an airtight container in the refrigerator for up to 3 days. To reheat, the microwave is actually a good friend here—just place it in a microwave-safe dish, add a tiny splash of water to keep things moist, and heat in 30-second intervals, stirring in between, until hot. You can also reheat it gently in a skillet over medium-low heat, stirring often. I don’t recommend freezing this one, as the broccoli can become mushy upon thawing.

Frequently Asked Questions

• Q: Can I use frozen broccoli? A: You absolutely can! There’s no need to thaw it first. Just add it straight from the freezer to the hot skillet. You may need to add an extra minute or two to the cooking time.
• Q: My sauce didn’t get very thick. What happened? A: This usually means the skillet wasn’t quite hot enough when the sauce was added. Don’t worry! You can mix a teaspoon of cornstarch with a tablespoon of cold water and stir it into the simmering sauce. It should thicken up in just a minute.
• Q: Is this one of those cheap dinners for a family? A: It really is! Flank steak is a relatively affordable cut, especially when you’re slicing it thin and stretching it with lots of healthy veggies. It’s a fantastic way to feed a family without breaking the bank.
• Q: What’s the best way to slice the beef so it’s tender? A: The most important tip is to always slice against the grain. Look for the lines running through the meat and cut perpendicular to them. This shortens the muscle fibers, making each piece much more tender to eat.
