Ingredients for beef and broccoli meal prep
Six ingredients for the beef, five for the sauce—plus one optional veggie swap.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| Broccoli Florets 🥦 | 3 cups | Bright green, trimmed stems |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For high-heat searing |
| Sesame Oil 🫒 | 1 tbsp | Toasted aroma only |
| Low-Sodium Soy Sauce 🥢 | ½ cup | Kikkoman preferred |
| Honey 🍯 | 2 tbsp | Local raw preferred |
| Garlic Cloves 🧄 | 6 cloves | Minced, fresh preferred |
| Fresh Ginger 🌿 | 1 tbsp | Grate finely, no peel |
| Cornstarch 🌾 | 1 tbsp | For sauce thickening |
| Sesame Seeds 🌰 | 1 tbsp | Toasted for garnish |

The flank steak is your secret weapon here. Ask the butcher for pre-sliced strips if you're short on time, but if you're slicing yourself, cut against the grain for that signature tender bite. I always grab mine from Whole Foods or Costco—look for good marbling and bright red color. For the broccoli, freshness matters most: the florets should snap when bent, not feel mushy. Trim the stems but leave them whole for that satisfying crunch. The sauce ingredients are all pantry staples, but Kikkoman soy sauce and local raw honey make the biggest difference in flavor.
No flank steak? Sirloin or ribeye strips work just as well—just slice them thinner. Short on ginger? Substitute 1 tsp ground ginger, but fresh is worth the few extra minutes. The cornstarch is non-negotiable for that perfect sauce consistency, but if you're gluten-free, arrowroot powder at the same amount works beautifully. For extra umami, add 1 tbsp fish sauce to the sauce (skip if vegetarian). The red bell pepper is completely optional but adds color and texture—swap in snap peas or mushrooms if you prefer. Pro tip: Toast your sesame seeds in a dry pan for 30 seconds before using—they'll taste a thousand times better.
This dish reheats like a dream—30 seconds in the microwave or 2 minutes in a skillet brings back that wok-fired crunch. Store in airtight glass containers for up to 5 days in the fridge, or freeze for 3 months. I always double the sauce and make extra beef—leftover sauce is perfect for stir-fries or marinades. The broccoli stays crispest when reheated quickly, so microwave with a damp paper towel for best results. Prep ahead? Store components separately—combine just before eating to keep everything fresh.

Step-by-step instructions for wok-fired beef and broccoli
Here's how to create restaurant-quality beef and broccoli with a meal-prep ready sauce that keeps its texture for days.
Marinate and Slice the Flank Steak
Place the 1.5 lb flank steak between two sheets of plastic wrap and slice it thinly against the grain into ¼-inch strips. This ensures tender bites that cook quickly in the wok. Transfer the sliced steak to a bowl and add 0.5 cup low-sodium soy sauce, 2 tbsp honey, 1 tbsp sesame oil, 1 tbsp minced fresh ginger, and 0.5 tsp ground black pepper. Mix well to coat completely, then refrigerate for at least 30 minutes—this tenderizes the meat and infuses it with flavor.
While the steak marinates, trim the 1 whole red bell pepper (if using) and slice it into thin strips. Set aside with the 3 cups broccoli florets—both will cook quickly in the wok. The red bell pepper adds a nice crunch and vibrant color to balance the broccoli's green.
Prepare the Sauce Base
In a small bowl, whisk together 1 tbsp cornstarch and 2 tbsp honey to create a smooth slurry. This will help thicken the sauce later. In a separate small bowl, combine 0.5 cup low-sodium soy sauce (reserve some for later if needed) and 1 tbsp minced garlic. The garlic should be finely minced—almost paste-like—to distribute evenly in the sauce.
Here's the thing—this sauce needs to coat the beef and broccoli perfectly without being gloppy. The cornstarch slurry is key for achieving that ideal consistency. If you're meal prepping, this sauce will thicken slightly when reheated, so don't over-thicken it now.
Wok-Fire the Beef and Vegetables
Heat a wok or large skillet over high heat until smoking, then add 0.5 cup extra-virgin olive oil. Once the oil shimmers, add the marinated flank steak in a single layer and let it sear undisturbed for 2-3 minutes until deeply browned. This creates that beautiful wok-hei (breath of the wok) flavor. Stir the steak occasionally to prevent sticking, then remove it to a plate and set aside.
In the same wok, add the 3 cups broccoli florets and red bell pepper strips (if using). Stir-fry for 3-4 minutes until the broccoli turns bright green and slightly blistered. The high heat will preserve the broccoli's crunch while developing its sweetness. Be careful not to overcrowd the pan—work in batches if needed.
Combine and Thicken the Sauce
Return the seared beef to the wok and add the garlic-soy sauce mixture. Stir everything together and let it cook for 1-2 minutes until the garlic is fragrant. Here's where it gets good—pour in the cornstarch-honey slurry and stir constantly for 1-2 minutes until the sauce thickens to a glossy, coatable consistency. You want it to cling to the beef and vegetables like silk.
The sauce should coat the back of a spoon but still be pourable. If it thickens too quickly, add 1-2 tablespoons of water to loosen it. Taste and adjust seasoning with a pinch more diamond crystal kosher salt if needed. The sauce should balance sweet, salty, and umami flavors perfectly.
Finish and Prepare for Meal Prep
Remove the wok from heat and stir in 1 tbsp sesame seeds and any remaining red bell pepper strips. The sesame seeds add a nutty crunch that contrasts beautifully with the tender beef. Transfer the beef and broccoli mixture to meal prep containers, dividing it evenly among 6 servings. The sauce should coat everything generously—each container should have a glossy, flavorful layer on top.
Let the meal prep containers cool to room temperature before refrigerating. This dish keeps well for 4-5 days in the fridge, making it perfect for busy weeks. When reheating, use a steamer basket or microwave with a splash of water to maintain the crisp-tender texture of the broccoli and beef.
Pro Tips For Making Beef And Broccoli Meal Prep
- Slice Against the Grain: Flank steak’s tough fibers run parallel to the grain—cutting perpendicular makes each bite tender. Use a sharp knife and slice at a 45-degree angle for cleaner, more uniform pieces (yes, it takes practice, but your future self will notice).
- Blanch Broccoli First: Toss florets in boiling water for 30 seconds, then ice bath. This keeps them bright green and prevents mush when reheating later. I used to skip it, and the broccoli always turned sad and limp by day three.
- Don’t Crowd the Pan: Cook the steak in a single layer over high heat—it needs room to sear, not steam. If you’re prepping for meals, work in batches. I learned this after a batch of gray, undercooked beef that tasted like regret.
- Finish with Sesame Oil: Add a splash of sesame oil after everything’s cooked, not before. It burns easily and needs to perfume the dish, not turn bitter. A teaspoon at the end makes all the difference—trust me, I’ve tried the wrong way.

Frequently asked questions
Can I use frozen broccoli instead of fresh?
Fresh broccoli gives the best texture, but frozen works in a pinch! Just thaw it completely first and pat dry thoroughly to prevent soggy meal prep containers. For extra crunch, stir-fry frozen broccoli for 1-2 minutes longer than fresh—this helps restore some texture after thawing.
How do I prevent the beef from drying out when reheating?
Reheat only what you need using high heat for 2-3 minutes in a skillet with a splash of water or sesame oil. Microwave reheating? Use a damp paper towel over the container to trap moisture. For best results, store beef and veggies separately in containers—combine just before eating to maintain crispness.
What's the best way to store this for meal prep?
Divide into airtight glass containers with tight-fitting lids, storing components separately if prepping ahead. The sauce will thicken slightly when refrigerated—just add 1 tsp water when reheating. Keeps 4-5 days in the fridge or 3 months frozen. Label containers with dates for freshness tracking!
Can I make this dish gluten-free?
Swap the soy sauce for tamari or coconut aminos (both gluten-free) and use arrowroot powder instead of cornstarch for thickening. The flavor profile remains identical—just ensure all other ingredients (like sesame oil) are certified gluten-free.
Why does my sauce get watery when reheated?
This happens when the cornstarch slurry isn't cooked long enough initially. For reheating, simmer the sauce alone for 1-2 minutes first to restore thickness, then toss with the beef and veggies. Pro tip: Make a smaller batch of sauce when reheating—it thickens more than expected after refrigeration.
